Shuibai Railway (also known as Shuibai Railway) is a single-track first-class electrified railway with a total design length of118,651km (main line). Its designed annual transportation capacity is100000 tons in the near future and180000 tons in the long term, which is the first one invested and constructed by the Ministry of Railways in Guizhou Province. Among them, the loan from China Development Bank is 600 million yuan, and the loan from Asian Development Bank is 65.438+0.05 billion US dollars. The line starts from Liupanshui City, Guizhou Province in the north, connects with Zhuzhou-Liuzhou double-track line, Guiyang-Kunming line, and then connects with Neijiang-Kunming line. South to Baiguo Town, Panxian County, Guizhou Province, and connected with the South (Ning)-Kunming (Ming) line. It is not only an important branch line of the Kunming Railway, but also a networking line of the two trunk lines of Nankun and Neikun. Its completion and opening to traffic not only enhanced the flexibility of the southwest road network and improved its layout, but also opened up a convenient sea passage for Sichuan, Chongqing, Guizhou and other provinces and cities. After the Shuibai Line was opened to traffic, the transportation distance from Chengdu to Guangxi via Neikun Line was shortened by more than 360 kilometers. 1 997 65438+February1Construction started, 2006 5438+0 65438+February 1 6 Shuibai Railway was completed.
Wumeng Mountain in Guizhou, where Shuibai Railway passes, has steep terrain and complicated ups and downs. The plateau here is anoxic, dry and desolate. There are many unfavorable geological phenomena such as coal seam gas, soft soil, landslide, debris flow, karst cave and water gushing. Almost all lines are connected by bridges and tunnels, and some stations are built on bridges and tunnels. From Maocaoping to Sanjiazhai Station, it is from the foot of the mountain to the top of the mountain. The railway has to detour four times on the mountain to reach Sanjiazhai Station. The minimum curve radius of the line is 450, the restricted slope 12, and the afterburner slope is 23.5%. There are 0/00 large and medium-sized bridges/kloc and 56 tunnels, and the total length of bridges and tunnels accounts for 63% of the national railway lines. Among them, Beipanjiang Bridge has a main span of 236 meters and a height difference of 280 meters from the deck to the bottom of the river bed. It is the longest bridge of its kind in the world and the highest railway bridge in China. Hejiazhai Tunnel, with a total length of 2,335 meters, is known as "the first hole in Asia". The longest tunnel is Songhe Tunnel, with a total length of 6,905 meters.
The mountainous area where Shuibai Railway passes is one of the poorest contiguous destitute areas in Guizhou, but it is also a resource-rich area dominated by high-quality coal. The whole line passes through three coalfields, with total reserves exceeding 5 billion tons. Therefore, after the opening of this railway, it can not only divert the freight volume of Guizhou-Kunming and Sichuan-Guizhou railways, but also alleviate the shortage of railway transportation in southwest China, and it is also of great significance to accelerate the development of local resources and the people's poverty alleviation.
If it refers to the highest railway bridge: Yarlung Zangbo River Bridge on Qinghai-Tibet Railway.
Qinghai-Tibet Railway is the plateau railway with the highest altitude and the longest route in the world. The highest point is at Tanggula Pass, which is 5072 meters above sea level. It is said to be the closest railway to heaven.
The highest railway station in the world-Tanggula Pass Station, with an altitude of 5068.63 meters.
Wind-volcano tunnel, the highest frozen soil tunnel in the world, is 4909 meters above sea level and has a total length of 1338 meters.
Kunlun Mountain Tunnel, the longest plateau frozen soil tunnel in the world, is 4648 meters above sea level and has a total length of 1686 meters.
Qingshui river bridge, the longest railway bridge built on frozen soil in the world, is 1 1.7 km long.
