What difficulties did you encounter in the construction of the Qinghai-Tibet Railway and how did you solve them?

One is the lack of oxygen in the mountains?

The second is the frozen soil problem?

The third is environmental protection?

Fourth, it does not affect animal migration?

Fifth, the terrain is complex?

One: In order to solve the problem that the lack of oxygen affects the work of the staff and makes the progress of the project slow, the engineers took the large oxygen generator to the plateau to provide sufficient oxygen for the engineers who built the tunnel. At that time, the oxygen content in the tunnel was only about 1000 meters above sea level, which greatly accelerated the progress of the project.

2. Frozen soil is the largest frozen soil research base in China and even the world. Since the construction of Qinghai-Tibet Railway started, the Ministry of Railways has attached great importance to the frozen soil research of Qinghai-Tibet Railway, and has arranged hundreds of millions of yuan for frozen soil research, organized experts from several scientific research institutions to conduct scientific research on five frozen soil engineering test sections of Qinghai-Tibet Railway, and obtained a lot of scientific research data and achievements. The frozen soil research of Qinghai-Tibet Railway draws lessons from the frozen soil construction experience of large-scale projects such as Qinghai-Tibet Highway, Qinghai-Tibet Oil Pipeline and Lanssila Optical Cable, and discusses and draws lessons from the frozen soil research achievements of Russian, Canadian and Nordic countries. At present, Chinese scientists have taken measures such as replacing roads with bridges, flaky ventilation subgrade, ventilation tube subgrade, gravel and flaky slope protection, hot rods, insulation boards and comprehensive waterproof and drainage systems. Great progress has been made in solving the problem of frozen soil. The Qinghai-Tibet Railway has become the largest frozen soil research base in China and even in the world. Engineers have driven thousands of cement piles into the plateau and buried them underground, which has provided sufficient support for the railway operation.

Three: In order to protect the rare wild animals in the blue sky, blue lake and plateau, the Qinghai-Tibet Railway has invested more than 2 billion yuan in environmental protection alone, accounting for 8% of the total project investment. At present, it is the largest railway construction project invested by China government in environmental protection, and it has introduced environmental protection supervision for the first time in national project construction, and signed environmental protection responsibility letters with local environmental protection departments for the first time.

Four: the staff opened the wildlife migration channel for the first time. Qingshui river bridge, located in the Hoh Xil National Nature Reserve, was specially built by the Qinghai-Tibet Railway for the migration of wild animals such as Tibetan antelopes. ?

In order to solve the terrain problem, engineers built Tanggula Station, the highest railway station in the world, which is also the highest railway station in the world at present.

The First Gao Qiao of Qinghai-Tibet Railway-Sanchahe Bridge?

Kunlun Mountain Tunnel, the longest plateau frozen soil tunnel in the world?

Wind-volcano tunnel, the highest plateau permafrost tunnel in the world?

China's largest plateau railway bridge base-Nanshankou Bridge Base of Qinghai-Tibet Railway?

The longest project of "replacing roads with bridges" on Qinghai-Tibet Railway-qingshui river bridge?

Known as "Tianlu", the Qinghai-Tibet Railway starts from Xining City, Qinghai Province, passes through Golmud City, Kunlun Mountain Pass and Tuotuo River, crosses Tanggula Mountain Pass, and enters Amdo, Naqu, Dangxiong, Yangbajing and Lhasa in Xizang Autonomous Region. The Qinghai-Tibet Railway, with a total length of 1956 km, is an important route into Tibet, known as the Heavenly Road, the highest plateau railway in the world and the longest railway on frozen soil. It is one of the four major projects in China in the new century. In September, 2065, it was selected as "Global Centennial Project", 438+03, which is a monument in the history of world railway construction.

Matters needing attention in Qinghai's visit to Tibet;

Pay attention to your health: most travel books suggest that it is best to start from the Qinghai-Tibet Highway when you go to the plateau for the first time. Because of the high altitude, almost everyone will have mild or severe altitude sickness. It is usually recommended to fly to Lhasa first, and get off the Qinghai-Tibet Highway when you get used to it.

Keep warm: May to 65438+ 10 is the best tourist season every year. It's too cold in winter and there are few tourists. Even if you take the Qinghai-Tibet Highway in midsummer, you'd better prepare winter clothes such as sweaters and down vests. Rain and snow are common, and the temperature may drop below 0 degrees Celsius.

Pay attention to diet: There are two kinds of diets on the Qinghai-Tibet Highway: most ordinary restaurants are "Sichuan cuisine", and Muslim restaurants are mainly pasta and mutton. Drivers running the Qinghai-Tibet line all know which food is delicious. Travelers can bring some fruits, dried fruits and chocolates.

Attention to self-drivers: For self-driving travelers, it is not recommended to pass through high-altitude areas as soon as possible. The relatively difficult section from Golmud to Lhasa is 1 100 km, which usually takes two days and more rest. Travel is not recommended. Accommodation can be in Naqu, Amdo or Dangxiong, with better conditions. (Information from Baidu Encyclopedia)
