Structure applied to soft backfill soil tunnel exit and construction method
The invention provides a structure and a construction method applied to a soft backfill soil tunnel to go out of a hole, and relates to the field of tunnel engineering. According to the structure applied to the soft backfill soil tunnel out-of-hole and the construction method, soft backfill soil is included, a reinforced concrete lattice frame is arranged on the upper surface of the soft backfill soil, a primary support is arranged on the reinforced concrete lattice frame, a plurality of drill holes are formed in the reinforced concrete lattice frame, and the drill holes are formed in the upper surface of the soft backfill soil. A micro steel pipe pile is arranged in each brick hole, a profile steel arch frame is installed in the soft backfill soil, a welding assembly is arranged on the frame face of each steel arch frame, each profile steel arch frame and the corresponding micro steel pipe pile are welded through the corresponding welding assembly, and twisted steel is arranged in each micro steel pipe pile. The twisted steel is used for placing the reinforcement cage, and the problem that safe and efficient construction supporting cannot be conducted on a tunnel when the tunnel faces extremely soft surrounding rock is solved.
本发明提供一种应用于软弱回填土隧道出洞的结构及施工方法，涉及隧道工程领域。该应用于软弱回填土隧道出洞的结构及施工方法，包括软弱回填土，所述软弱回填土上表面设有钢筋混凝土格构框架，所述钢筋混凝土格构框架上设有初期支护，所述钢筋混凝土格构框架上开设有若干个钻孔，每个所述砖孔内均设有微型钢管桩，所述软弱回填土内安装有型钢拱架，所述钢拱架架面设有焊接组件，每个所述型钢拱架与所述微型钢管桩之间通过焊接组件焊接，每个所述微型钢管桩内部均设有螺纹钢筋，所述螺纹钢筋用于钢筋笼的安放解决了在面对极其软弱的围岩时，隧道不能够进行安全高效的施工支护的问题。
