The line leads from jinji village Station of Gui Xiang Railway, goes west along Youjiang Valley, passes through Jiangxi Village, Wang Bu, Na Tong, Long 'an, Pingguo, He Na, Tiandong Northeast, Tian Yang and Baise, then enters Guizhou in Ba Du, then passes through Yang Xu and Pei 'ai, and then divides into two ways: all the way west into Yunnan, passing through Funing, Bailazhai, Guangnan, Zhulin and Puzhehei.
This section basically belongs to the line along the river in hilly areas, and the project is concentrated in the section from Lucheng to Ba Du. Mihualing Tunnel is a full-line control project. There are altogether 85 bridges 185 (including 73 large bridges and extra large bridges), 64 culverts 1 164 tunnels. * * * There are 39 stations.
20 14 12.23, the second line project of Nanning-Baise section of Nanning-Kunming Railway started construction. The second double line of Nanning-Baise section of Nanning-Kunming Railway is located in Guangxi Zhuang Autonomous Region, passing through Nanning, Long 'an, Pingguo, Tiandong, Tian Yang and Baise, with a total length of 276 kilometers.
Nanning-Kunming Railway1990 officially started construction in February,1997 was laid in March and put into operation in February. It is a national Class I electrified railway trunk line with an annual transportation capacity of 6.5438+million tons and a long-term capacity expansion of 30 million tons. The line leads from Jiangxi Village Station of Gui Xiang Railway, along the west of Youjiang Valley, passes through Long 'an, Pingguo, Tiandong, Tian Yang, Baise and Tianlin, enters Guizhou Province in Ba Du, passes through Ceheng, Anlong and Xingyi to Weishe, and then divides into two roads: all the way west into Yunnan Province, and passes through Fuyuan, Luoping, Shizong, Luliang, Shilin, Yiliang and Chenggong County to Kunming. The Journey to the West entered Panxian County, Guizhou Province, and took over Guo Hong Station of West Railway. Among them, the Nankun Line is 828 kilometers long and the Weihe Red Line is 68 kilometers long.
The new construction project of Nanning-Kunming Railway includes the main line with a building length of 863438+0km and its supporting projects; Introduction project of Nanning and Kunming hubs and electrification project of the whole line.
The Nanning-Kunming Railway is a long trunk line built in a dangerous mountainous area. It is rare for the railway to climb the Yunnan-Guizhou Plateau from the Beibu Gulf seaside, with a relative height difference of 20 10 meter. Among them, there are eight ups and downs due to river crossing. There are 447 bridges and 258 tunnels, and the project is arduous and complicated. Among them, some projects will create many records of railway construction in China. For example, qingshui river bridge, with a bridge height of183m, is the highest railway bridge in China. Banqi Second Bridge became the first curved railway beam bridge in China. Ba Du Nanpanjiang Bridge 100-meter-high pier has rewritten the 70-meter-high record of existing bridges in China, and the V-shaped bearing on the pier is the first time on China Railway Bridge. Mihualing Tunnel, with a total length of 9392 meters, is the longest single-track tunnel in China. The railway crosses expansive soil (rock), karst, soft soil area, debris flow, landslide prone area and octave earthquake area, which urges the foundation treatment and new retaining structure to adopt various high-level technical countermeasures. The long tunnel excavation of Jiazhuqing Tunnel in high gas stratum and high stress area has greatly improved the advanced geophysical prediction and disaster prevention technology of tunnels in China. Through scientific research and practice, these new technologies have raised the road construction technology in China to a new level.
The east section of Nanning-Kunming Railway started on February 24th 1990, and the west section started on February 24th 199 1 19. 1April 993 18, Guizhou section started. Guizhou, Yunnan and Guangxi "go hand in hand", and/kloc-0 was completed and put into operation at the end of 997.
