Subway tunnel construction technology
The invention discloses a subway tunnel construction process. The construction operation of a first supporting structure is carried out by combining a cast-in-situ bored pile with a steel pipe inner support supporting system at an open excavation section; excavation operation is conducted in the open excavation section in a running water construction mode; underground excavation operation is conducted on the underground excavation section through a step ascending and descending method; excavation operation is conducted on the vertical shaft and an over-crossing electric power square ditch section; earthwork backfilling operation is conducted on the ground of the open excavation section, the underground excavation section, the vertical shaft and the over-crossing electric power square ditch section; according to the construction method, the subway tunnel is divided into the three construction sections, and the open excavation mode and the underground excavation mode are adopted for construction according to the specific construction state of each construction section, so that the advantages of the open excavation method and the underground excavation method are considered, and efficient and safe construction is achieved.
本申请公开了一种地铁隧道施工工艺，通过在明挖段采用钻孔灌注桩结合钢管内支撑支护体系进行第一支护结构的施工操作；在明挖段采用流水施工方式进行挖掘操作；在暗挖段采用上下台阶法进行暗挖操作；在竖井及上跨电力方沟段进行挖掘操作；以及在明挖段、暗挖段、竖井及上跨电力方沟段的地面进行回填土方操作；即将地铁隧道拆分为三个施工段，并且根据各个施工段的具体施工状态分别采用明挖和暗挖的方式施工，从而兼顾了明挖法和暗挖法的优势，实现了高效、安全施工。
