What Is The Underground Water Railroad?

What was the Underground Railroad and how did it work?

• During the era of slavery, the Underground Railroad was a network of routes, places, and people that helped enslaved people in the American South escape to the North. The name “Underground Railroad” was used metaphorically, not literally. It was not an actual railroad, but it served the same purpose—it transported people long distances.

Is there a train that runs under the ocean?

Japanese and French trains run through what are currently the world’s two longest undersea tunnels: the 54km Seikan Tunnel in northern Japan, of which 23km is beneath the sea; and the 50km Channel Tunnel between the United Kingdom and France, 38km of which is under the sea.

Where does the underwater train go?

The Channel Tunnel (also referred to as the Chunnel) is a 50.46-kilometre (31.35 mi) railway tunnel that connects Folkestone (Kent, England, UK) with Coquelles (Hauts-de-France, France) beneath the English Channel at the Strait of Dover.

Is there an underwater train in America?

A 13,000km-long railway line from China to the USA, running partially underwater to cover the Bering Strait. It is not to be confused with the Bering Strait Tunnel, which is only the part crossing the Bering Strait. This has been on the wishlist of engineers for centuries.

Was there really an underground railway?

Nope! Despite its name, the Underground Railroad wasn’t a railroad in the way Amtrak or commuter rail is. It wasn’t even a real railroad. The Underground Railroad of history was simply a loose network of safe houses and top secret routes to states where slavery was banned.

Could a tunnel be built under the Atlantic Ocean?

A transatlantic tunnel is a theoretical tunnel that would span the Atlantic Ocean between North America and Europe possibly for such purposes as mass transit. Some proposals envision technologically advanced trains reaching speeds of 500 to 8,000 kilometres per hour (310 to 4,970 mph).

How deep underwater is the Eurotunnel?

At its deepest, the tunnel is 75 metres (246 feet) below the sea level. That’s the same as 107 baguettes balancing on top of each other.

How long is the underwater train from London to Paris?

The Chunnel tunnel is 31.3 miles (50.56 km) in length and it takes a Eurostar train approximately 35 minutes to travel its full length. In total, the fastest journey time from London St.

Is there a train from Russia to Alaska?

The TKM–World Link (Russian:, English: Transcontinental Railway) also called ICL-World Link (Intercontinental link) is a planned 6,000-kilometer link between Siberia and Alaska providing oil, natural gas, electricity, and rail passengers to the United States from Russia.

Where is Eurotunnel tunnel?

The Channel Tunnel or Chunnel is a 50km-long undersea rail tunnel below the Strait of Dover in the English Channel. It is one of the longest underwater tunnels in the world and connects Folkestone in Kent, UK, with Coquelles in Pas-de-Calais, France.

Does the train from Paris to London go underwater?

Eurostar is the service that allows you to catch a train from London to Paris and beyond. There’s a sea in the way, of course, but Eurostar dives under it, using the 31-mile Channel Tunnel. Work on the tunnel began in 1988, and it was finally opened for business in 1994, costing £4.6 billion.

Is the train from London to Amsterdam underwater?

Yes. Trains from London to Amsterdam do go underwater. In fact, the Channel Tunnel (or “Chunnel” if you prefer its nickname) is just over 31 miles (50 km) in length and is the longest continuous underwater tunnel in the world.

Were quilts used in the Underground Railroad?

Two historians say African American slaves may have used a quilt code to navigate the Underground Railroad. Quilts with patterns named “wagon wheel,” “tumbling blocks,” and “bear’s paw” appear to have contained secret messages that helped direct slaves to freedom, the pair claim.

Who built the Underground Railroad?

In the early 1800s, Quaker abolitionist Isaac T. Hopper set up a network in Philadelphia that helped enslaved people on the run.

How far did the Underground Railroad go?

Because it was dangerous to be in free states like Pennsylvania, New Jersey, Ohio, or even Massachusetts after 1850, most people hoping to escape traveled all the way to Canada. So, you could say that the Underground Railroad went from the American south to Canada.

Underwater Railways – Everything You Need To Know

The Mumbai – Ahmedabad bullet train, which is expected to be operational by 2023, will not only be the country’s first bullet train, but it will also be the country’s first underwater train. Out of the 508 kilometers between Mumbai and Ahmedabad, 21 kilometers will be routed underground and seven kilometers will be routed beneath the seabed. Meanwhile, the city of Kolkata is preparing to build the world’s first underwater metro system, which would run beneath the Hoogly River. What do you know about underwater trains, now that you think about it?

History Of Underwater

Engineering advancements in the construction of tunnels sturdy enough for transportation began in the 19th century with the work of English engineers. The London Subway Network, which was built for the purpose of moving coal, was the first subterranean system suggested. Historical records indicate that the first tunnel was constructed near Kibblesworth in 1855 as a test tunnel before their project in London was completed. The world’s first underwater railway tunnel was 396 meters long and was 23 meters below the surface of the river.

From there, numerous countries began to minimize travel time by constructing railroad tunnels beneath the ocean’s surface.

Will China ever build an underwater train all the way to the US?

Given their troubled history and present, establishing a purpose-built link between the United States and China might be difficult. Large-scale collaboration between the superpower and the would-be-superpower would be required.

Nonetheless, there were various press stories in 2014 claiming that an underwater railway was in the works at the time. It’s possible to score an environmental and diplomatic victory. But, seven years later, there’s still no evidence of anything happening. As a result, we decided to look into it.

From China to the US in just two days

According to reports from 2014, the 8,078-mile-long train voyage would take passengers from China through Russia and then Canada before reaching at its final destination, the United States. It would be underwater throughout this 125-mile portion of the train’s journey across the Bering Strait (a small waterway between the Pacific and Arctic Oceans). Although Chinese officials were still deciding on the path that the train would follow, they maintained that it was doable. According to an article published in the state-run journal China Daily, the government has the technology and resources necessary to achieve a project of this magnitude.

Apparently, Russia has been thinking about this for a long time : “In an interview with theGuardian, Wang Mengshu, a railway expert at the Chinese Academy of Engineering, explained his thoughts.

Travelers would be able to complete the journey from Europe to the United States in just two days.

Will the ambitious project go ahead?

The South China Morning Post was skeptical of the first anticipated expenses of $200 billion (€170 billion), which the paper estimated to be too expensive. As a result, current reports suggest that the project may be put on hold. However, it is worth noting that plans for the Channel Tunnel were delayed for 180 years before the tunnel connecting the United Kingdom and France was finally completed in 1994. The earliest proposal for an underground link between Britain and France came from French engineer Albert Mathieu-Flavier in 1802; however, it wasn’t until 1987 that the British and French parliaments decided to proceed with the project.

The world’s largest high-speed rail network

Ongoing discussion surrounds whether or not the railway will really be constructed. However, considering the fact that China currently has a vast rail network, it is a possibility. A high-speed rail network of more than 23,000 kilometers in length connects the nation to the rest of the world. It also includes the Shanghai maglev, which is the world’s fastest commercial electric train. It is possible to travel by magnetic levitation train between Shanghai Pudong Airport and Longyang Road, which is located in the city’s eastern region.

From the standpoint of the environment, China is increasing its investments in rail travel in order to reduce CO2 emissions from both the automobile and aviation industries.

The China-Russia-Canada-America railway would need a significant financial investment, and many people believe that it would be pointless because ocean transportation routes already exist and should be utilized instead of building a new one.

Some have also questioned whether China and Russia would be likely to collaborate on this project, considering the history and current political tensions between the two countries.

Would the China-US train line be environmentally friendly?

Trains are largely regarded as the most ecologically friendly mode of public transportation available today. For every kilometer traveled by train, the greenhouse effect of gas emissions is 80 percent lower than that of automobiles. Furthermore, a normal railway route can transport up to 50,000 people every hour. A railway ride emits only 14 grams of CO2 per passenger every kilometer traveled, compared to around 285 grams for air travel. Furthermore, high-speed rail lines, which may be utilized for both passenger travel and freight transportation, are extremely efficient modes of transportation.

When it comes to reducing the number of polluting transpacific flights, Earl tells Euronews Green that “the fundamental question we should ask is whether or not this would genuinely lower the number of polluting transpacific flights.” However, he emphasizes that “any new transportation solution must both address growing transportation emissions while also operating on clean, renewable power,” as he concludes.

China Wants To Build An 8,000-Mile Underwater Train Line To The USA

China presently possesses one of the most extensive and remarkable high-speed rail networks on the planet, and it shows no indications of slowing down in the near future. As their network extends to the most remote parts of their country, it is possible that Beijing is turning its attention to what is beyond — far, far beyond. According to reports, China intends to construct a high-speed train that will run from mainland China, up through Siberia in Eastern Russia, under the sea through the Bering Strait into Alaska, across the rocky peaks of Canada’s Yukon and British Columbia, and into the United States, before terminating in Los Angeles.

• What is the cost of such an outrageous proposal?
• Even billionaires like Jeff Bezos are unlikely to be able to afford such a hefty price tag.
• Several news sites reported the story.
• It would need an undersea tunnel four times the size of the Channel Tunnel, and it would be significantly more high-tech as well.
• Engineers from China said at the time that they were already in discussions with Russian officials about constructing the line, which they were certain would be achievable with present technology.
• As of 2018, China has granted approval for the construction of the world’s first underwater bullet train, which would run from Ningbo, a port city near Shanghai, to Zhoushan, an archipelago of islands off the country’s eastern coast.
• It will be a Maglev train, which will levitate above a magnetic track while being propelled along at tremendous speeds, and building on the mammoth project is well advanced.
• However, despite the fact that nothing is known about the progress of the China-Russia-Canada-America line, some have speculated that the Ningbo-Zhoushan line may serve as a type of trial run for a much larger project.
• They might be a little more behind than expected.
• The line, which cost $22 billion, was a significant step forward for the United States’ railway network, which had previously lagged behind other countries.
• In spite of how magnificent a line connecting the countries of China, Russia, Canada and the United States would be, it appears to have been placed on hold for the time being.

While it is possible that they are correct, the tensions between the world’s superpowers imply that such an alliance, which would represent the world’s most expensive megaproject in history, might be little more than a pipe dream in the near future.

Underwater train in Kolkata: India’s first underwater train to be launched in Kolkata soon

The first underwater train in India is expected to arrive in Kolkata in the near future, according to the Union Railways Minister, who said that the majority of the work on the train project has been done and that metro train services would begin shortly. “The first underwater railway in India, which will run beneath the river Hubli, will begin operations in Kolkata soon. This train, which has superb engineering, serves as a testament to the advances made by Indian Railways. The people of Kolkata will benefit from this railway, and the people of India will be proud of their accomplishment.” Piyush Goyal, the rail minister, made the announcement on Twitter yesterday.

1. In the words of Piyush Goyal (@PiyushGoyal), 1565254929000 is a good number.
2. The metro line is comprised of twin tunnels of 520 metres in length and 30 metres below the riverbed.
3. When the train goes through the tunnel at an average speed of 80 kilometers per hour, the segment between Howrah and Mahakaran metro stations will remain under the river for for approximately a minute.
4. Approximately one million people per day are expected to be transported by the project by 2035, according to Railways estimates.

Seikan Tunnel, Japan

Tunnel under the railroad

Estimated Investment

The Japan Railway Construction, Transport, and Technology Agency is responsible for the construction, transportation, and technology of railroads in Japan. The Seikan tunnel connects Japan’s Honshu and Hokkaido islands, and it is the world’s longest tunnel. The tunnel has a total length of 23.3 kilometers of submerged route. Rugby471 provided the image used in this post. The Honshu side of the Seikan tunnel has its own entrance. LERK provided the image for this post. The platform for the Yoshioka-Kaitei Station is located within the Seikan tunnel.

1. Aomori Prefecture on Honshu Island is connected to Hokkaido Island by the 53.85-kilometer-long Seikan railway tunnel, which runs through the Tsugaru Strait and passes beneath the Tsugaru Strait.
2. It is also the world’s deepest and longest railway tunnel.
3. The Seikan tunnel’s conceptual design was developed over the years 1939 to 1940.
4. The Japan Railway Construction, Transport, and Technology Agency conceived and built the $3.6 billion project, which is operated by JR Hokkaido Railway.

Locomotives of the ED79 and EH500 classes transport freight and provide nightly sleeping car services through the tunnel. Commenced in March 1988, both the freight and passenger services were operational. In March 2018, the Tunnel celebrated the 30th anniversary of its inauguration.

Seikan tunnel project details

The track at the Seikan tunnel is a triple slab track that is capable of supporting Shinkansen bullet trains. Among the tunnel’s many features are two railway stations: the Tappi Kaitei on Honshu Island and the Yoshioka Kaitei on Hokkaido Island, which are the world’s first railway stations to be built beneath the sea and which also serve as emergency escape routes in the case of a calamity. In order to ensure passenger safety, the stations are fitted with exhaust fans to exhaust smoke, infrared fire warning systems, and water spray nozzles to increase passenger safety.

Unlike the main tunnel, which is connected to the service shaft, the pilot shaft acts as the service tunnel for the middle 5km section of the tunnel.

Throughout the year, an underground temperature of 20 degrees Celsius and a relative humidity of 80 to 90 percent are maintained.

Seikan tunnel construction

Construction began in September 1971 and was completed in 1972. The tunnel’s cross section is intended to make it easier for Shinkansen trains to pass through. The first point of interaction between the two sides occurred in 1983. The building of the tunnel involves drilling and blasting through an earthquake-prone area of the ground. There were approximately 2,900 tons of explosives and 168,000 tons of steel utilized in the tunnel building process. Construction on the main tunnel’s entry portion began in August 1982 and was completed in December 1982.

The building of the undersea segment was finished in March 1985, according to official records.

The tunnel was originally built with a single gauge rail, but it was later upgraded to a double gauge track and linked to the Shinkansen network as part of the Hokkaido Shinkansen project in 2005.

There were three bores constructed for the purpose of constructing the tunnel’s undersea section, which included an initial pilot tunnel, a service tunnel, and the main tunnel.

Future developments for the Seikan rail tunnel

To replace the ED79 and ED500 classes of electric locomotives, Toshiba’s EH800 Bo-Bo+Bo-Bo Series electric locomotives began running through the tunnel in 2014. The new electric locomotives will be 25 meters long and have a power rating of 4 megawatts, with a top speed of 110 kilometers per hour. The tunnel will also enable the passage of the Shinkansen bullet train, which will begin operating there in 2016. The tunnel’s present electric system will be updated from 20kV to 25kV in order to accommodate the Shinkansen trains, which will run at a higher voltage.

After the first two years of operation, train speeds will be limited to 140km/h in order to eliminate the possibility of narrow gauge freight trains traveling in the other direction being derailed by shockwaves of air. The following are the topics covered in this article:

China green lights first underwater high-speed railway

(CNN) – The U.S. Department of Agriculture (USDA) is urging farmers to plant more crops in the coming year. China’s high-speed rail ambitions will not be slowed down any time soon. Beijing has just given the green light to a project to construct China’s first underwater bullet train track. There will be a direct connection between Ningbo, a port city south of Shanghai, and Zhoushan, an archipelago off China’s east coast. The proposed underwater tunnel will be a part of the 77-kilometer Yong-Zhou Railway plan (Yong is Ningbo’s nickname), which aims to enhance tourism and establish a commuting zone inside Zhejiang Province that takes no more than two hours to complete.

A total of 70.92 kilometers (47.8 miles) of new railway tracks will be constructed along the 77 kilometers (47.8 miles) long line, which will include a 16.2 kilometers (miles) submerged segment.

Line to significantly shorten journey

If the Yong-Zhou Railway is finished, high-speed trains will run between Ningbo East Station and Zhoushan (Baiquan) Station at a maximum speed of 250 kilometers per hour, connecting the two major cities in China. The new line, which will connect to the huge high-speed rail network that already exists in China, would take travelers from Hangzhou – the main city of Zhejiang – to Zhoushan in only 80 minutes. The current trip time by bus is around 4.5 hours, or a 2.5-hour drive by personal automobile.

Additionally, a road-rail bridge will be constructed to connect different portions of the archipelago, in addition to the underwater tunnel.

Easy access to Boeing’s new China factory

When it comes to foreign travelers, Zhoushan, located about three hours south of Shanghai, is still a relatively unknown destination. However, in terms of business, it is one of the most notable new state-level regions (also known as special economic-development zones) in China, having been declared by the Beijing government. The Ningbo-Zhoushan Port is the busiest port in the world in terms of cargo throughput, and it is located in China. Zhoushan is also the site of Boeing’s first overseas facility, which is expected to commence operations in December 2018.

What, on the other hand, is there for ordinary tourists?

The Underground Railroad Route

Students will learn how to distinguish between slave states and free states during the time of the Underground Railroad, as well as the difficulties of escaping and choosing the path they would have chosen. Geography, Human Geography, and Physical Geography are the subjects covered. Students should be able to distinguish between slave and free states throughout the time of the Underground Railroad. Each pupil should be given a copy of the map titled “Routes to Freedom.” Inform pupils that the Underground Railroad aided enslaved individuals as they traveled from the South to the North during the American Civil War.

Students should be instructed on how to use the map key. Afterwards, instruct pupils to locate each slave state on the map as you pronounce its name:

• Alabama
• sArkansas
• sDelaware
• sFlorida
• sGeorgia
• sKentucky
• sLouisiana
• sMaryland
• sMississippi
• sMissouri
• sMontana This state does not display on the map since it is not included in the list. Make use of a wall map of the United States to instruct children on where Montana is located.) North Carolina, South Carolina, Tennessee, Texas, and Virginia are among the states represented.

Explain to pupils that enslaved individuals did not have access to maps, compasses, or GPS systems throughout their time in slavery. The majority of enslaved individuals were never permitted to get an education, and as a result, they were unable to read or write. Consider the following question: How do you suppose enslaved people knew they were heading in the correct direction? Students should be informed that enslaved individuals resorted to guides on the Underground Railroad, as well as memory, visuals, and spoken communication to survive.

• Talk about the difficulties you’ve encountered on your path.
• Instruct pupils to examine the map and make note of any physical characteristics of the region that made the voyage challenging.
• In order to demonstrate proper shading techniques, students should go to Alabama, then northeast via Maine and into Canada to see how the Applachian Mountains are shaded.
• Ask:Can you think of anything else that made the travel difficult?

• In the winter, being cold and outdoors
• Not having enough food
• Being exhausted yet unable to relax
• Having to swim or traverse bodies of water
• Having to travel great distances
• Evading or avoiding people or animals

3. Ask pupils to identify the route they would have chosen if they were in their shoes. Students should be divided into small groups. Ask each group to look at the map and choose the route they would have gone to freedom if they had been able to do so. Students should choose their selections based on the states, rivers, and mountain ranges that they would have to cover on their journey. Ask each group to describe the path they would have followed and why they would have done so.

Informal Assessment

Students should discuss what they believe to be the most difficult obstacles to fleeing enslaved people, such as distance, weather, mountains, wildlife, bodies of water, or densely inhabited places, among other things. Inquire as to how their chosen method might have assisted enslaved individuals in avoiding the difficulties they were faced with.

Learning Objectives

Students will be able to:

• The student will be able to identify slave states and free states during the time period when the Underground Railroad was active
• Describe the difficulties encountered throughout the voyage
• Indicate the path they would have followed, and explain their reasons.

Teaching Approach

• Common Core Standard 1: How to interpret and share information via the use of maps and other geographic representations, geospatial technology, and spatial thinking
• Standard 17: How to use geography to understand and interpret the past.

What You’ll Need

• Highlighters, paper, pencils, and pens, as well as a wall map of the United States

Chunnel, Channel tunnel and Eurotunnel

An underground passageway between southern England and northern France, known as the Channel Tunnel (or simply the “Chunnel”), was completed in 1937. Besides operating a train shuttle (Le Shuttle) between Folkestone and Calais, Getlink also operates a car, van, and other vehicle transportation service between the two cities. European high-speed passenger services through the Channel Tunnel connect London with a number of major European cities on the continent, including Paris, Brussels, Lille, Lyon, Avignon, and Marseille.

Eurostar is a completely independent company and Getlink’s largest customer. The Chunnel is really made up of three tunnels: two rail tunnels, which are used for both freight and passenger trains, and a service tunnel. The rail tunnels are connected by a bridge.

How long is the Chunnel?

The Chunnel is 31.5 miles (50.45 kilometers) long. That’s the equivalent of stacking 169 Eiffel Towers on top of each other in a single building. It is the longest undersea tunnel in the world at 23.5 miles (37.9 kilometers), with a length of 23.5 miles (37.9 kilometers) under the English Channel.

When was the Chunnel built?

The concept of building a tunnel across the English Channel was initially mentioned in 1802; however, work did not begin until 1988. It was finished in 1993, and Eurostar services began operating there in November of that year.

Where is the Chunnel?

The Chunnel is a tunnel that connects the ports of Folkestone in south Kent with Calais in northern France. In Folkestone, the vehicle traffic for Le Shuttle arrives, and it departs in Calais. In terms of distance from London, Folkestone is around an hour and a half away, and Calais is roughly three hours away from Paris. Eurostar trains, which are exclusively for passengers, depart from London’s St Pancras International station (some services additionally stop at Ebbsfleet and Ashford in Kent) and go directly to the heart of Paris and the other Eurostar destinations around Europe.

How deep is the Chunnel?

The tunnel reaches a depth of 75 meters (246 feet) below sea level at its deepest point. That’s the same as stacking 107 baguettes on top of each other and counting them.

How was the Chunnel built?

The Channel Tunnel is comprised of three different tunnels that run parallel to one another in the same direction. There are three train tunnels: one going south (from the United Kingdom to France), one running north (from France to the United Kingdom), and one service tunnel. All three tunnels were dug beneath the seabed and connect the towns of Folkestone in Kent with Coquelles in Pas-de-Calais, France. However, the concept of building a tunnel connecting the United Kingdom and France is more older than most people realize – it dates back to the early 1800s, when advocates included Napoleon Bonaparte.

In addition to hand tools, a cutting-edge boring machine was employed to complete the project.

Who can travel through the Chunnel?

The Eurostar service connects our UK stations (London St Pancras International, Ebbsfleet International in north Kent, and Ashford International in south Kent) with our continental stations. People who want to travel by car or bus between Folkestone and Calais can take use of the Eurotunnel Le Shuttle service. Before traveling by Eurostar or Eurotunnel, you will be required to pass through security, customs, and ticket checks. This is also true before traveling through the Tunnel.

How much did it cost to build the Chunnel?

The construction of the Channel Tunnel took little under six years and 13,000 men to complete. According to official figures, the overall cost rose to a staggering £4.65 billion, which would be the equivalent of £12 billion in today’s money.

5 crazy ways to cross the Channel

• Captain Matthew Webb made history on August 25, 1874, when he became the first person to swim across the English Channel from England to France. He tried the voyage for the first time on August 12, 1874, but was forced to abandon it owing to heavy winds and severe waves. He was not deterred, and he attempted a second time 12 days later. With the assistance of three boats and a layer of porpoise oil on his skin, he made it to Calais in 21 hours 45 minutes despite difficult tides and a jellyfish bite. Sarah Thomas, an American swimmer, broke a world record in September 2019 when she became the first person to swim across the English Channel four times non-stop, breaking the previous mark of three. After a remarkable swim of 54 hours and 10 minutes, she finished her epic journey.

2. In a wingsuit

• A carbon wing was used by Felix Baumgartner on July 31, 2003, when he leapt out of an aircraft 30,000 feet (9,100 meters) above Dover and soared for 22 miles (35.5 kilometers) at a high speed of 220 miles per hour (350 km). Six minutes later, he touched down in France, making him the first person to do it in a wing suit over the English Channel. His first words to the media after landing were, “For the final 2,000 meters, I could see the other side and realized that I was going to make it”
• He added, “I knew I was going to make it.”

3. By bathtub

• On May 17, 2007, the comedian Tim Fitz Higham made history by being the first person to row across the English Channel in a bathtub. Tim tried this remarkable endeavor for the first time in 2004, but was forced to abandon it after becoming trapped in a storm with force 6 winds. Tim had to learn to row before attempting the crossing, and he did so with the British Olympic rowing squad throughout his preparation. Tim was able to complete the exhausting trek in nine hours and six minutes. On his arrival, he spoke to press about his plans “Rowing is something that can’t be faked
• You either have the ability or you don’t. It’s a draining experience. Because you’re using so much energy and exerting effort in every part of your body, your heart and lungs are working overtime to keep up with you “in addition to this, if you have any questions, please don’t hesitate to contact me at [email protected]

4. By waterski

• Water skiing across the English Channel was accomplished by Christine Bleakley, host of The One Show, on March 12, 2010, covering the 21-mile (34-kilometer) distance in in 100 minutes. In spite of the fact that she was scared of water and admitted that she was not a great swimmer, she became the first person to water-ski across the world’s busiest shipping lane. She donated thousands of pounds for Sport Relief as a result of her efforts, and after completing the challenge, she expressed her gratitude “It’s hard for me to believe I’ve actually accomplished this. It was quite difficult “in addition to this, if you have any questions, please don’t hesitate to contact me at [email protected]

5. By balloon

• Jonathan Trappe crossed the English Channel on May 28th, 2010, while attached to 54 industrial strength helium balloons. Jonathan began his extraordinary voyage in a field near Ashford and went on to become the first cluster-balloonist to cross the English Channel in his category. The 36-year-old explorer drifted in the air for four hours before landing in a cabbage patch in France, narrowly missing death after evading a power line that he had avoided. Following his arrival, Mr Trappe stated: “Although the flight was excellent, the landing was quite difficult. I’m quite pleased with myself. I think it’s an excellent thing that you’ve done “in addition to this, if you have any questions, please don’t hesitate to contact me at [email protected]

6. By hovercraft

• On August 4, 2019, Franky Zapata, a Frenchman, became the first person to cross the English Channel using a jet-powered hoverboard. In the wee hours of the morning, he took off from Sangatte, at the Pas de Calais area of France, and landed in St Margaret’s Bay, just beyond the white cliffs of Dover, to thunderous cheers from well-wishers. Franky was able to complete his trip in only 22 minutes, traveling at speeds of up to 110 mph (177 km/h) between 15 and 20 meters above the surface of the ocean. It was his second attempt at the expedition
• His previous effort ended in disaster when he crashed into the sea while attempting to land on a vessel to refuel in the middle of the route. Despite the fact that he had lost two fingers during his hoverboard’s first flight in his garage, Franky felt unafraid to continue with his odd endeavor.

tunnels and underground excavations

Tunnels and subterranean excavations are horizontal underground passageways created by excavation or, on rare occasions, by nature’s action in dissolving a soluble rock, such as limestone, in a controlled environment. A shaft is a term used to describe a vertical hole. Underground passages serve a variety of purposes, including mining, transportation (including roads, railroads, subways, and canals), and the conveyance of water and waste. Subterranean chambers, which are frequently linked together by a network of connecting tunnels and shafts, are increasingly being used for a variety of purposes, including underground hydroelectric power plants, ore processing plants, pumping stations, vehicle parking, oil and water storage, water-treatment plants, warehouses, and light manufacturing; in addition, command centers and other special military requirements are being accommodated.

Authentic tunnels and chambers are excavated entirely from the inside out, with the above material left in place, and then lined as necessary to provide support for the neighboring ground.

A hillside tunnel entrance is known as aportal.

Tunnels beneath the sea are currently typically constructed employing an immersed tube system: long, prefabricated tube sections are floated to the site, buried in a trench, and then filled with backfill to complete the construction.

History

It is likely that the first tunneling was carried out by prehistoric humans who were attempting to expand their cave systems. Tunneling techniques were established by all of the great ancient civilizations. InBabylonia, tunnels were extensively utilized for irrigation, and a brick-lined pedestrian route of 3,000 feet (900 metres) in length was erected under the Euphrates River between 2180 and 2160 BC to connect the royal palace with the temple, according to archaeological evidence. During the dry season, a diversion of the river was necessary to complete the construction.

• For example, the Abu SimbelTemple on the Nile, which was constructed in sandstone about 1250 BC for Ramses II (and which was torn up and transported to higher land in the 1960s to prevent flooding from the Aswan High Dam), was built in sandstone around 1250 BC for Ramses II.
• Aqueducts, such as the 6th-century-bc Greek water tunnel on the island ofSamos, which was driven through limestone and had a cross section about 6 feet square, were built by both the Greeks and the Romans to recover marshes via drainage and to transport water.
• By that time, surveying procedures (most typically using a string line and plumb bobs) had been developed, and tunnels were constructed by advancing them from a series of closely spaced shafts to enable ventilation.
• This eliminated the need for a lining.
• In AD41, the Romans expended over 30,000 men over a ten-year period to push a 3.5-mile (6-kilometer) tunnel to drain the Lacus Fucinus river.

When miners were freemen, much more attention was paid to ventilation and safety precautions, as evidenced by archaeological excavations at Hallstatt, Austria, where salt-mine tunnels have been dug since 2500bc and have been discovered.

From the Middle Ages to the present

Because the minimal tunneling that existed throughout the Middle Ages was primarily for mining and military engineering purposes, the next significant advancement came in the 17th century to address the rising transportation demands of Europe. The Canal du Midi (also known as Languedoc) tunnel in France, constructed in 1666–81 by Pierre Riquetas part of the first canal between the Atlantic and the Mediterranean, was the first of several majorcanaltunnels to be built throughout history. Gunpowder was deposited in holes drilled by handled iron drills to create a tunnel with a length of 515 feet and a cross section of 22 by 27 feet.

1. The Bridgewater CanalTunnel, constructed in 1761 by James Brindley to transport coal from the Worsley mine to Manchester, is one of the most prominent canal tunnels in the United Kingdom.
2. Despite the fact that canals were phased out with the arrival of railroads around 1830, the new mode of transportation resulted in a significant surge in tunneling, which persisted for over a century as railroads extended around the world.
3. Tunneling on the Manchester-Sheffield Railroad’s Woodhead Tunnel (1839–45) began with five shafts that reached a depth of 600 feet and ran for 3.5 miles.
4. A mix of canal and train systems, it was constructed in 1831–33 to transport canal boats through a mountain pass.
5. Initial projections predicted completion in three years; in reality, it took 21 years, in part because the rock proved to be too difficult for either manual drilling or a crude power saw to cut through.

Despite its difficulties, the Hoosac Tunnel made significant contributions to tunneling technology, including one of the earliest uses of dynamite, the first use of electric firing of explosives, and the introduction of powerdrills, initially powered by steam and later by air, which eventually led to the development of the compressed-air industry today.

1. The construction of the first of them, the Mont Cenis Tunnel (also known as the Fréjus Tunnel), took 14 years (1857–71) to finish its length of 8.5 miles.
2. On top of that, Sommeiller designed an air drill that allowed the tunnel to be moved forward at a rate of 15 feet per day.
3. In order to complete this lengthy tunnel, surveying techniques had to be developed because it was driven from two heads separated by 7.5 miles of steep terrain.
4. Other notable Alpine railroad tunnels were built soon after, including the 9-mileSt.

Simplon, nearly 7,000 feet below the mountain crest, encountered major problems from highly stressed rock flying off the walls in rock bursts; high pressure in weak schists and gypsum, necessitating the construction of 10-foot-thick masonrylining to resist swelling tendencies in local areas; and high-temperature water (130° F), which was partially treated by spraying from cold springs to reduce swelling tendencies in local areas.

1. Driving Simplon as two parallel tunnels with many crosscut connections greatly assisted ventilation and drainage in a significant manner.
2. In the middle of a tunneling project under the Kander River valley, an unanticipated flood of water, gravel, and shattered rock filled the tunnel for a total length of 4,300 feet, burying the whole workforce of 25 men.
3. At 590 feet, the tunnel tapped the Kander River, allowing the river and soil from the valley fill to pour into the tunnel, resulting in a massive depression, or sink, at the surface.
4. The majority of long-distance rock tunnels have had difficulties with water inputs.
5. A lengthy series of unusually big inflows forced the engineers and workers to adapt, the first of which killed 16 men and buried 17 others until they were recovered after seven days of burrowing under the wreckage.
6. After much deliberation, Japanese engineers came up with the solution of creating a parallel drainage tunnel that would run the whole length of the main tunnel.

Aside from that, they used compressed-air tunneling with shield and air lock, which is a technology that is virtually unheard of in mountain digging.

Subaqueous tunnels

It was thought that tunneling beneath rivers was impossible until Marc Brunel, a French émigré engineer, created a protective barrier in England. The first time the shield was used was in 1825, when Brunel and his son Isambard were building the Wapping-Rotherhithe Tunnel through clay beneath the Thames River. The tunnel was a horseshoe portion 221 / 4by 371 / 2feet in length, with a brick liner on the inside. In 1841, the Brunels succeeded in completing the world’s first true subaqueous tunnel, a 1,200-foot-long tunnel that took essentially nine years of work.

• When Peter W.
• It was in 1874 that Greathead made the subaqueous technology truly viable through modifications and automation of the Brunel-Barlow shield, as well as by adding compressed air pressure within the tunnel to keep back the water pressure from the outside.
• Compressed air was utilized to keep the water at bay in this first attempt.
• Greathead spent so much time and effort perfecting his process that it was effectively utilized for the following 75 years without any substantial changes.
• Once subaqueous tunneling became economically feasible, the Greathead shield was used to create many railroad and subway crossings, and the method eventually proved to be suitable for the much bigger tunnels necessary for vehicles.
• Holland and his chief engineer, Ole Singstad, solved the ventilation problem by installing huge-capacity fans in ventilating buildings at each end of the bridge, forcing air through a supply duct below the roadway and an exhaust duct above the ceiling.
• Such ventilation requirements resulted in a huge increase in tunnel size, with a two-lane vehicle tunnel requiring a diameter of around 30 feet.
• Since 1950, however, the immersed-tubemethod has been the technique of choice for most subaqueous tunnelers.
• This fundamental process was first used in its current form on the Detroit River Railroad Tunnel between Detroit and Windsor, Ontario, which was constructed between 1906 and 1910.

The ability to avoid the high costs and dangers associated with operating a shield at high air pressure is a significant benefit, as work inside the buried tube is done at atmospheric pressure (free air).

Machine-mined tunnels

The Oahe Dam on the Missouri River, in Pierre, South Dakota, was the site of the culmination of sporadic attempts to actualize the tunnel engineer’s ambition of a mechanicalrotaryexcavator in 1954. Despite favorable ground conditions (a readily cuttable clay-shale), success was achieved by a collaborative effort with Jerome O. Ackerman as principal engineer, F.K. Mittry as original contractor, and James S. Robbins as builder of the first machine—the “Mittry Mole”—and other individuals. Later contracts resulted in the development of three additional Oahe-type moles, resulting in the machine mining of all of the numerous tunnels here, which totaled eight miles of 25- to 30-foot diameter.

An air-powered rotary cutting arm, theBeaumont borer, had been constructed for a pilot tunnel in chalk that had been started under the English Channel, and this was a major inspiration for the development of theOahe mole.

In 1962, the American improvement of the mechanical raise borer, which benefited from prior testing in Germany, made a breakthrough in the more difficult excavation of vertical shafts, which was equivalent to the breakthrough made in the previous year in Germany.
