【摘要】：我国城市轨道交通建设正处于快速发展阶段,如何实现城市核心区隧道施工机械化,减少施工对城市的干扰已成为一个关键性问题。文章结合具体工程实例,通过对沿线施工条件的分析,提出了符合城市核心区实际情况的隧道工筹方案;并对复合式TBM井下整体始发、过站转场、洞内调头、平移吊出及相应临时工程改造等关键技术进行了详细阐述,得出了可靠的结论。研究结果表明,以上关键技术的实施避免了房屋拆迁,减少了对城市交通的干扰,解决了施工场地难题,实现了复合式TBM连续、快速掘进,确保了车站及区间的总工期,减少了工程浪费,节约了工程投资;结论对重庆及其它地区类似工程具有一定的借鉴意义。
[Abstract]:The construction of urban rail transit in our country is in the rapid development stage. How to realize the mechanization of tunnel construction in the urban core area and reduce the interference of construction to the city has become a key problem. Based on the analysis of the construction conditions along the line, the tunnel construction plan which accords with the actual situation of the urban core area is put forward. The key technologies such as the whole origin of compound TBM downhole, the turning field of the passing station, the turn in the tunnel, the displacement and hoisting and the corresponding temporary engineering renovation are elaborated in detail, and the reliable conclusions are obtained. The implementation of the above key technology avoids the house demolition, reduces the interference to the urban traffic, solves the construction site problem, realizes the compound TBM continuous, fast tunneling, and ensures the total construction period of the station and section. The waste of the project is reduced and the investment of the project is saved. Conclusion it is useful for similar projects in Chongqing and other regions.
