This will accumulate experience for the construction and design of domestic large tunnels in the future.
1.3.2 Overall construction program
This section has steep and complicated terrain, and the distance between the exit of Nanliang Tunnel and the inlet of Taihangshan Tunnel is 184m, with Lushan Bridge in the middle, which connects the bridge and tunnel. And Taihangshan Tunnel inlet end of the site is narrow, production, living facilities layout difficulties, the tunnel out of the ballast through the existing highway, the highway is currently being rebuilt, the construction period is longer, construction interference, is the section of the schedule of the controlling project, the construction of the Taihangshan Tunnel inlet area as the focus and the difficulty of the construction of the specialized construction according to the requirements of the organization of the large-scale mechanized operations.
The whole section will be divided into two operation sections and three project teams will be arranged for construction. After entering the site, to the Taihangshan Tunnel inlet area as the focus, in the construction preparation period to focus on priority to complete the construction of its approach road, bridge construction work, for the tunnel inlet end as soon as possible to form the construction site and construction site construction to create the conditions. The construction takes the method of building points and construction, and strives to create conditions for the early entry of Taihangshan Tunnel inlet end. At the same time, accelerate the reconstruction of the existing road and the construction of temporary roads in the Lushan inclined shaft area, in order to create conditions for the organization of large-scale construction equipment to enter the site quickly.
Lone mountain bridge due to terrain conditions, construction, the plan is set up between the Taihangshan Tunnel inlet and Nanliang Tunnel exit cable cranes, for the construction of the Lone mountain bridge materials, templates, etc. to create conditions for the transportation of the bridge. After the construction of Lushan inclined shaft, the first arrangement of the inclined shaft and Nanliang Tunnel main hole junction to the mouth of the section of the construction, Nanliang Tunnel exit through, the fan from the inclined shaft inlet to the mouth of the end of the solution to the construction of the main hole ventilation problems, and then the organization of the inclined shaft and the main hole junction to the construction of the section of the demarcation of the mileage. Lone Mountain Bridge 0 # platform to be Nanliang Tunnel exit after the passage of construction, 3 # platform in the Taihangshan Tunnel inlet hole after the completion of the construction of earth and stone immediately after the organization of the construction, while in the left and right lines of the bridge platform in the middle of the masonry retaining wall, backfill compaction of ballast in the hole on which the air compressor room, ventilator, etc., in order to solve the Taihangshan Tunnel inlet construction site is narrow, part of the production facilities is difficult to arrange the problem. And due to the Taihangshan Tunnel inlet and Lushan Bridge 3 # platform connection, the hole site is narrow, the construction of the road layout is difficult, so the tunnel left and right line inlet hole buffer structure arrangements in the tunnel excavation is completed before the construction, in order to solve the bridge and tunnel are connected to the hole construction of the road is difficult to lay out the problem.
