Sichuan Tibet railway is the most valued and evaluated railway in China! Another quick report

On November 2, Bayu tunnel of Lhasa Linzhi section of Sichuan Tibet railway was successfully completed. In the process of construction, the highest record of 7015 meters of single head driving of plateau railway tunnel was set. Bayu tunnel is the largest plateau railway tunnel in the world with the strongest rock burst, the longest single head driving distance and the largest buried depth in China. It is called "the tunnel with stones flying like shells" by the builders. The builders have overcome thousands of rock burst threats and have safely run through the whole tunnel

if a worker wants to do a good job, he must first sharpen his tools. Sichuan Tibet railway is known as another "Heaven Road" after Qinghai Tibet railway, and it is recognized as the most difficult railway to build. In the face of various "difficult and miscellaneous diseases", the emergence of high-tech equipment has become an inevitable trend. It is reported that the total length of the main tunnel of Bayu tunnel is 13073 meters, the total length of the horizontal guide is 9481 meters, and the highest temperature is about 47 degrees Celsius. 94% of them are located in the rockburst area. The intensity and frequency of rockburst are high. Generally, the duration of rockburst reaches 2 to 6 hours, lasting for more than a week at most, and even there will be two rockbursts a few months later. This is very rare in the world tunnel construction history. In addition, limited by special geographical conditions, the tunnel can not be set with auxiliary tunnels, only from the two ends of the entrance and exit stubborn. We are not afraid of obstacles, overcome difficulties and move forward step by step to success A 6031 a 6031 foreigners call us "infrastructure maniacs", which make things impossible for foreigners to accomplish possible again and again. Similarly, China's railway constantly creates miracles and writes brilliance. As an important throat of the Lalin railway, Bayu tunnel takes only 15 minutes for the train to pass through. It is estimated that after the 200 km / h Sichuan Tibet railway is opened to traffic, the train time from Chengdu to Lhasa will be reduced from the original 43 hours to about 13 hours, and the traffic time will be reduced by about one third. The convenient Sichuan Tibet railway will connect Tibet with the Yangtze River Economic Belt, and then it will become a convenient land passage from China to South Asia The construction of the Sichuan Tibet Railway in

is more necessary to promote national unity, maintain national unity and consolidate the stability of the border areas. With the further development of the "belt and road" construction, the western region has become the forefront of China's opening up, and its vitality will be further revitalized. The relationship between the western region and the world economy will be closer and closer, and the road of opening up will be wider and wider. The plan and construction of Sichuan Tibet railway was launched in an all-round way, making Tibet a hot spot in China's economic map, showing a brighter development prospect. After the completion of the Sichuan Tibet railway, it will become another major artery from the roof of the world to the mainland after the Qinghai Tibet railway, which is of great significance to the development and construction of Sichuan and Tibet, as well as to the ecological protection, especially to the maintenance of the stability of the border areas and national security
