History of Qinghai-Tibet Railway Construction

1. History and Construction of Qinghai-Tibet Railway May 7, 2007: Construction of Qinghai-Tibet Plateau Railway. Brief introduction of Qinghai-Tibet Railway started at 1958. In April of that year, the section from Hekou to Xining of Lanqing Railway started construction from Hekou in western Lanzhou and Xining in Qinghai at the same time.

Get More Achievements The Qinghai-Tibet Railway runs from Xining City in Qinghai Province to * * City in * * Autonomous Region, with a total length of 1.956 km, of which the section from Xining to Golmud is 8 1.4 km, 1.984. The newly-built Golmud-* * section starts from Golmud City, Qinghai Province along the Qinghai-Tibet Railway. Qinghai-Tibet Plateau in China is one of the highest plateaus in the world, known as the roof of the world, with complex geological structure, unstable strata and many geological activities. Under such conditions, it is difficult to build a railway.

2. Construction materials or pictures of Qinghai-Tibet Railway The Qinghai-Tibet Railway has a total length of 1956 km, with an altitude of more than 4,000 meters and 960 km, of which 550 km passes through the plateau permafrost region.

Its highest point is located at Tanggula Pass, with an altitude of 5072 meters, and it is covered with snow all year round. It is known as "the closest railway to the sky" and "the highest railway in the world". Building the Qinghai-Tibet Railway is an important strategic decision made by the CPC Central Committee and the State Council at the beginning of the new century. It is one of the four landmark projects in the Tenth Five-Year Plan and the first key project in the western development.

The Qinghai-Tibet Railway starts from Xining City in Qinghai Province in the north and ends in * * * City in * * Autonomous Region in the south, with a total length of about 1956 km, of which about 846 km from Xining to Golmud was completed in 1984. The Golmud-* * section of the Qinghai-Tibet Railway, which is about to start construction, leads from Golmud Railway Station, an important town in the west of Qinghai Province, passes through Nanshankou, goes to the hinterland of the Qinghai-Tibet Plateau, passes through Nachitai, Wudaoliang, Tuotuo and Yanshiping, crosses Tanggula Mountain, enters the * * * autonomous region, and then passes through Amdo, Naqu, Dangxiong and Yangbajing, and reaches the capital of the * * * * autonomous region.

The route is basically parallel to the Qinghai-Tibet Highway. The Qinghai-Tibet Railway passes through nature reserves such as Hoh Xil, Sanjiangyuan and Qiangtang. Because of its unique environmental protection design and construction, it is also called the first "environmental protection railway" in China.

Qinghai-Tibet Railway is the highest and longest plateau railway in the world today. The area above 4000 meters above sea level is 960 kilometers, and the highest point crossing Tanggula Mountain is 5072 meters. After years of continuous frozen soil section of 550 kilometers, it passes through the 9-degree earthquake intensity zone of 2 16 kilometers.

Along the line, it is cold and anoxic, with fragile ecological environment and active crustal movement. Building a railway in such an area is very exploratory and scientific, and the construction task is arduous.

The Fenghuoshan Tunnel is the highest railway tunnel in the world. Kunlun Mountain Tunnel is located at an altitude of 4,767 meters, with a total length of 1686 meters, making it the longest frozen soil tunnel in the world. The construction of the Qinghai-Tibet Railway will end the history that the * * * autonomous region is closed to railways, further improve the traffic conditions and investment environment of the Qinghai-Tibet Plateau, and promote the development of resources and rapid economic development.

It will play an important role in strengthening the ties between the mainland and * * *, promoting cultural exchanges between Tibetans and ethnic groups, enhancing national unity and benefiting people along the route. The Qinghai-Tibet Railway starts from Xining, Qinghai in the east and reaches * * * in the west. It is the plateau railway with the highest altitude and the longest route in the world. After four years of construction, it was put into trial operation in July 2006.

It will become the most famous plateau gold tourist route in the world. There are 9 world-class tourism resources and 23 national tourism resources, including 6 national nature reserves and scenic spots such as Ta 'er Temple, Treasure Beach atomic city, Chaerhan Salt Lake, Mount Everest, * * * Ancient City and Barkhor Street, and 193 ordinary tourism resources.

Behind these unparalleled natural landscapes, Tibetan culture accumulated for thousands of years is also reflected. ?????????????????????????????976/p & gt； Tibet Train Plateau Tibet Train is the most advanced train carriage in China at present, with two sets of oxygen supply systems. In order to resist the harsh natural environment such as strong winds, dust and strong ultraviolet rays on the Qinghai-Tibet Plateau, the trains entering Tibet are fully enclosed; The toilet uses a vacuum toilet collector, and the waste water is recycled by special equipment; The joint between carriages adopts a fitted coupler, so there will be no air leakage.

In order to cope with the anoxic environment in the Qinghai-Tibet Plateau, the oxygen concentration, temperature and pressure in the train compartment can be kept in balance. The configuration of each train is almost the same as that of an airplane. There are two sets of oxygen supply systems: one is "distributed" oxygen supply, which keeps the oxygen content of each carriage at 23% through the air in the hybrid air conditioning system, so that passengers can feel like entering the "oxygen bar"; The other is an independent oxygen inhalation interface. If passengers need more oxygen, they can wear a mask to breathe at any time to avoid altitude sickness.

If the train walks at an altitude of more than 4000 meters, you will feel as if it is more than 3000 meters. The actual altitude can be reduced by 1000 meters, which can alleviate the discomfort caused by altitude hypoxia. In addition, the interior decoration of the train entering Tibet is luxurious and modern, which fully shows the ethnic customs of the Qinghai-Tibet region, and a comfortable restaurant and bathroom will be set up.

In addition to oxygen supply equipment, medical staff, instruments and medicines are also prepared, and a tourist life support system is established to help guests adapt to the plateau climate smoothly and reduce plateau reflection. Driving time The whole running time of the Shanghai-Tibet line train is estimated to be about 52 hours.

It is estimated that it will take 45 hours from Chengdu to * * *. Xining to * * * is expected to take 22 hours.

Golmud to * * * Estimated 12 hour. Qinghai-Tibet Railway is the highest plateau railway in the world: the railway crosses 960 kilometers above 4000 meters above sea level, and the highest point is 5072 meters above sea level.

The longest plateau railway in the world: Golmud-* * section of Qinghai-Tibet Railway, with a total mileage of 1 142 km. The longest plateau railway crossing frozen soil in the world: the railway has a mileage of 550 kilometers crossing permafrost for many years.

The Tanggula Mountain Railway Station at an altitude of 5068 meters is the highest railway station in the world. The wind-volcano tunnel at an altitude of 4905 meters is the highest frozen soil tunnel in the world.

The total length of Kunlun Mountain Tunnel is1686m, which is the longest plateau frozen soil tunnel in the world. Anduo Pujia base, at an altitude of 4,704 meters, is the highest Pujia base in the world.

Qingshui river bridge, with a total length of 1 1.7 km, is the longest railway bridge on plateau and frozen soil in the world. After the completion, the speed of Qinghai-Tibet Railway will reach 100 km in frozen soil section and 120 km in non-frozen soil section, which is the highest speed of railway trains in plateau frozen soil in the world at present.

Hello, LZ in the construction of Qinghai-Tibet Railway.

The Qinghai-Tibet Railway was built in three stages.

Xige section (Xining-Golmud) is the earliest section. 1958 started construction, 1979 formally laid track, 1984 operated. The capacity expansion and transformation of this section of railway was studied by 1999, which was implemented in coordination with the development of the western region. Dual-track construction began in 2007 (due to

Golmud-* * * section started on June 29th, 2006, and was completed on June 30th, 2005. It was officially opened to traffic on July 30, 2006, and it was seamlessly replaced and rebuilt from June 29 to June 20, 2006543812.

La Ri section (* * *-Shigatse) started on September 26th, 20 10, and was opened on August 6th, 20 14.

In addition to the above-mentioned three-phase projects that have been in normal operation, the railway branches of Lalin (* * *-Linzhi) and Riya (Xigaze-Yadong) will be built before 2020.

4. Building the roof of the information world of Qinghai-Tibet Railway, which is a "forbidden area of human life". Biologists assert that the Qinghai-Tibet Plateau.

From the mainland to * * *, it was once difficult to go to the sky. Princess Wencheng has been to Tibet for more than two years. Now from Xining to * * *, the bus can run in two days. Drivers can let their "iron horses" gallop freely on the Qinghai-Tibet Highway. Drivers who drive at a low speed are often ridiculed by their peers as "old cows slow horses".

Wencheng should be safe and sound, and it will surprise the world-heaven and earth seem to shorten the distance between time and space because of the road! 1954, the Qinghai-Tibet highway with a total length of 1948 km was completed and opened to traffic. This road starts from Xining and passes through Golmud to * * *, which is the main national defense and economic road leading to the southwest frontier of the motherland. After several large-scale renovations and renovations, today's Qinghai-Tibet Highway is a highway that can enter and exit * * * all the year round, bearing 85% of the passenger traffic and 90% of the freight traffic in the whole region, and is known as the "lifeline" of * * *.

But how many people know how bad the road conditions on the Qinghai-Tibet Plateau are? How many people know what efforts and sacrifices highway engineers and technicians have made before knocking on the door of the "forbidden zone" and building this "road to heaven"?

Worldwide problems

Ice peaks, snow-capped mountains, storms, intense ultraviolet rays and severe hypoxia are natural signs of the Qinghai-Tibet Highway. In particular, the section from Golmud to * * *, with an altitude of 4000m to 523 1m, should cross Kunlun Mountain, Fenghuo Mountain, Nyainqentanglha Mountain, and cross the plateau frozen soil area with harsh ecological environment and complicated geological conditions for more than 630 kilometers. A large area of continuous, island-like permafrost and seasonal permafrost, coupled with underground ice, ice piles, ice mounds, hot melt lakes and ponds and other adverse geological conditions, have formed the unique geology and landforms of the Qinghai-Tibet Plateau.

When the Qinghai-Tibet Railway was built, the story was 1. In March, Qingdao Morning Post reported that a girl 16 years old in Qinghai-Tibet suffered from a strange disease, and her height was only about 1 meter. Her mother sought medical treatment everywhere and finally found a hospital that could treat her children, but the cost was too high.

In order to save her daughter, the mother decided to sell her kidneys to raise money. 2. China Railway 11th Bureau is responsible for track-laying and bridge prefabrication of Amdo-* * section of Qinghai-Tibet Railway, and has completed the power engineering tasks of 443km track-laying on the main line, nearly 80km track-laying on the station line, 899 holes of beam erection and 42 1 km from Thawing Spring to Tanggula Mountain.

The low temperature of MINUS 40 degrees, strong altitude sickness, hard living conditions and bad working environment have not stopped the builders from advancing. They wrote their own life answers on the snowy plateau. 3. In the 6,543,800+construction army of Qinghai-Tibet Railway, there is an active "red female soldier", which is a track-laying production team composed of 26 female employees of China Railway 11th Bureau, and is known as "Snow Lotus who has entered the forbidden zone of life".

This group of girls from "Land of Fish and Rice" laughed and said that they were "half asleep and half awake, and they were not hungry when eating, and they didn't know whether it was a man or a woman", but they set a world record for the daily output of plateau track arrangement and won many honors such as "National May 1 Labor Award" and "National May 1 Women's Award". "Couples communicate by SMS, and arrogant children are called aunts when they meet."

The touching scene details moved the audience. Participating in the construction of the Qinghai-Tibet Railway is the purification and sublimation of the soul.

Guang Jun ended his report with an adapted military song "For Who": "For Who, for the soaring of the west, for the beauty of the motherland. Hand in hand with the silver line to * * *, ushered in the whistle of the snowy plateau and the soaring of the iron dragon.

Although bitter and tired, I have no regrets about dedicating my youth to the motherland and the people! "。
