Through the knowledge collation of architectural knowledge column of this website, Zhong Da Consulting has the following basic information about Qinling Tunnel:
Basic survey of Qinling Tunnel:
Qinling Tunnel: At present, China Railway Highway has crossed the Qinling Mountains seven times: the first time was in the 1950s when baoji-chengdu railway Panshan crossed the Qinling Mountains; The second time is to build the Qinling tunnel of Xikang Railway; The third time is Xi 'an Nanjing Railway East Qinling Tunnel; The fourth time is Zhongnanshan Tunnel of Baomao Expressway (xikang high-speed), the fifth time is Qinling Tunnel Group of Xihan Expressway (Jingkun Expressway), the sixth time is West Qinling Tunnel of Lanzhou-Chongqing Railway, and the seventh time is Qinling Tunnel Group of Xicheng High-speed Railway under construction.
In order to help the construction enterprise personnel further understand the Qinling Tunnel Group in expressway in the Western Han Dynasty, Zhong Da consulted and compiled relevant information, and the basic situation is as follows:
General situation of expressway Qinling Tunnel Group in Western Han Dynasty;
Expressway in the Western Han Dynasty is a section of the National expressway Network G5- Jingkun expressway Shaanxi, and it is an important part of the main skeleton of the "Mi"-shaped highway in Shaanxi Province. The highway starts from Laomeiyukou, Huxian County in the north, passes through ningshan county, connects with the completed Xi 'an to expressway, Mianxian County in the south, and connects with Mianxian County to Ningqiang expressway under construction. The main line of the route is 258.65km long, and the whole line is built according to the standard of two-way four-lane expressway. According to the terrain conditions, the driving speed is 60- 100km/h, the subgrade width is 20-26m, and it is fully enclosed and interconnected.
Expressway Qinling Tunnel Group Project Planning in Western Han Dynasty;
Huxian to Mianxian expressway pass through the main mountain range of Qinling Mountains, with deep ravines, complex terrain conditions, many bridges and tunnels, high engineering and technical requirements, and extremely difficult construction. The main engineering quantity of the whole line design is: subgrade earthwork is 30.899 million cubic meters, including excavation14.086 million cubic meters, filling16813,000 cubic meters, and bridge 147264.785 linear meters /723. Among them, bridge 53289. 1 linear meter /66 medium bridge1164.28 linear meter/164, small bridge 2637.7 linear meter/133; The total length of a single tunnel is 974 13.5 linear meters/1, including 48554 linear meters/10 for extra-long tunnel, 4982 linear meters/10 for medium-long tunnel and 23847 linear meters /63 for medium-long tunnel. Interchange 15, 28 separated interchanges; There are 653 culverts and 236 passages; The pavement is 4.355 million square meters. There are 1 management office, 4 management offices, 15 toll station, 5 service areas and 4 maintenance work areas.
