Hot wire! Nanning Metro Line 5 first shield double section through!
Recently, the shield between Nahong interchange station and Jinkai Road Station of Civil Engineering Section 2 of Nanning Metro Line 5 Bid 01 has been successfully connected!!! It marks the completion of the shield section contracted by the civil engineering 2 work area, becoming the first work area where the shield double sections of the whole line are all connected, which is completed 5 days in advance, providing a strong guarantee for the completion of the whole line of Metro Line 5.
Two shield sections from Nahong interchange station to Jinkai Road station to Jinkai Road station to Jiangnan Park Station contracted by civil engineering zone 2, with a total length of 3.36km. The geology of the section is mainly mudstone, in which the first 100m of the starting section of Najin section is the mudstone at the lower part of the upper round gravel layer, which is soft on the upper part and hard on the lower part, making the construction difficult; the section is located under Zhuangjin Avenue, which needs to pass through Zhuangjin overpass, two pedestrian overpasses, style rainforest community, rainwater and sewage pipes, gas pipes, with high construction risk.
Nanning Metro Line 5
Nanning Metro Line 5 phase I project starts from Nahong in the South and ends at Jinqiao passenger station in the north, with a total length of 20.21km, all underground lines and 17 stations. Among them, Nahong interchange station, Guangxi University Station, Mingxiu Road station and xiaojicun station are transfer stations. Open cut construction is adopted for all stations, and shield method is mainly adopted for construction of section tunnel.
As an important part of the second round of construction planning of Nanning rail transit, line 5 (Nahong Jinqiao passenger station), line 2 East extension (Yudong tanxing Village), line 3 (Keyuan Avenue Pingle Avenue), line 4 (Nanning South Station Xincun) and other lines together constitute the second round of construction planning of Nanning rail transit (the planning was approved by the State Council on January 21, 2015 and approved by the State Council Approved by the national development and Reform Commission). After the completion of the second round of construction plan in 2021, it will form a rail transit operation network of about 128.2km.
Transfer with line 1 to line 4 from southwest to Northeast
It can be seen from the schematic diagram of Nanning Metro Line 5 phase I project that, as an auxiliary line connecting the southwest and northeast of Nanning, line 5 passes through Jiangnan group, Chengxi group and Chengbei group from the south to the north, breaking the barrier of Yongjiang to the north and south of the city. The line connects Jiangnan area, Jiangbei area, Jinqiao passenger station and other major areas. It also connects the major external transport hubs through the subway network through the transfer with metro lines 1, 2, 3 and 4, forming a fast channel between the hubs and strengthening the hub advantage of Nanning in the regional transport network.
