Technology Puzzle
Nanshuang Railway over the mountain Yue Ring, crossing Jiangyue River, the total line bridge tunnel is 312.8 kilometers, accounting for 54.2% of the total line 469 bridges a total of 180.1 kilometers, accounting for 31.2% of the total length of the line; 135.7 kilometers of the tunnel, accounting for 23.0% of the total length of the line. The construction of Nanchuang Railway needs a bad environment such as vacuum area, geological crushing, rock is rich in water, rock, hard rock, shallow bias.
Key Projects
● Yujiang Special Bridge
Guiping Yujiang Double Line Bridge is one of the controlled projects of Nanchuang Railway, for Asian's first waist triangle Structural bridge, full length is 11.326 kilometers; the main bridge is (36 + 96 + 228 + 96 + 36) m-double tower double roped steel trophic gap, and a semi-floating system. The bridge is located on the Guitang section of Guijiang to Guiping, the bridge is in the II level channel, and reserves the design requirements of the I-level channel design of 3,000-ton ship; the bridge is designed to design the highest navigation water level of 42.670, the minimum navigation water level is 28.768 The navigation clearance height is not less than 13 meters; the navigation clearance width single hole double direction is not less than 150 meters.
● Xijiang Special Bridge
Nanguang Railway Xijiang Shi Bridge is one of the controlled projects of the whole line, which is the largest bridge in the world's similar railway bridges in the 2010. 618.3 meters; wherein the main bridge is a centralized steel box tap arch bridge, a spray of 450 meters; the arch rib is a high degree of steel box structure, and each segment is designed according to the principle of "with a discount", and its gyroscope section is at the time. Raising the world; the bridge surface adopts the binding beam system of steel longitudinally beam and reinforced concrete bridge panel. The location where the bridge is located is complex, the water is surprising, the venue is narrow, and the construction is difficult.
● Beiling Mountain Tunnel
Beiling Mountain Tunnel is located in Zhaoqing, Guangdong Province, one of the land controlled projects of Nanchong Railway, 12.438 kilometers, the largest deep Buried 568 meters, a total of 3 causations were designed. The tunnel hole crossing the area of the area, the hucosa-changing layer, and the large Xiangkou is three-stage bad geological band. The rock resist is mainly based on quartz sandstone, surrounding rock fertility, crack development, rock mass break, crack water development, tunnel import Segment shallow burying development. The phenomenon of spring water repeats, construction difficulties and risk are large during the tunnel construction period. The construction unit adopts super-level geological forecasting means such as advanced horizontal diamond, infrared water, TSP, mainly using the laminated grouting and water sections to carry out advanced support, overcome the difficult factors of construction.
● Hua Riling Tunnel
Pope Tunnel is one of the four major controlled projects of Nanchuang Railway, and the west end is located in Dadun Village, Dadu Town, Cangwu County, Guangxi Zhuang Autonomous Region. The east end is located in Guilong Village, Baolong Village, Yuan County, Guangdong Province, with a total length of 5,918 meters, and has "a hole in two wide".scientific research results
Nan Guang Railway Xijiang Shi Bridge won the 2016 China Steel Structure Engineering Award.
Construction plan
June 29, 2016, China State Council principles passed the "medium and long-term railway network plan", Nan Guangshi Railway included China "eight-year" high-speed railway Guangkun Channel line.
Value meaning
Nanguang Railway is an important part of China's "medium and long railway network planning", which is also a key project in China's central and western railways. After this railway passes through the car, it will further improve the Structure of the Central and Western Railway Network, which greatly reduces the time and space between the cities, not only will change in the southeast of Guangxi, especially the population-intensive Fuji County, Guiping, Pingnan, Cangwu, etc. There is no railway history, and these areas further integrate into China's fast railway network, and accelerate the modernization process.
