Construction method of subway station composite structure
The invention relates to a construction method of a subway station composite structure, which is applied to a subway station. Comprising the following steps: closing a road of a second structural area, and constructing a supporting structure below the road; the first structural area is constructed through an open excavation method, and after the first structural area is subjected to open excavation to the preset elevation, a small pilot tunnel is constructed in the underground excavation area; the second structural area is constructed through a PBA construction method, and after the small pilot tunnels are communicated, middle piles and steel pipe columns of the subway station are constructed in the small pilot tunnels; lower-layer earthwork of the second structural area and the third structural area is excavated synchronously, and main body structure bottom plates, longitudinal beams, cross beams and side walls corresponding to the earthwork are constructed; and the common underground diaphragm wall and the construction platform plate of the second structural area and the third structural area are dismantled, and the first structural area is excavated in an open-cut mode to sequentially and upwards construct the structure. The technical problem that in the prior art, construction of a subway station matched with a high-speed rail station is interfered by construction of other matched facilities is solved.
本发明涉及一种地铁车站组合结构的施工方法，应用于地铁车站；包括：封闭第二结构区的道路，并施作道路下方支护结构；对第一结构区采用明挖法进行施工，在对第一结构区进行明挖至预设标高后，向暗挖区施工小导洞；对第二结构区采用PBA施工法进行施工，小导洞贯通后在小导洞内施作地铁车站的中桩和钢管柱；同步开挖第二结构区和第三结构区的下层土方，并施作对应土方的主体结构底板、纵梁、横梁和侧墙；拆除第二结构区和第三结构区的共用地连墙和施工站台板，明挖第一结构区依次向上施作结构。本发明缓解了现有技术中存在的与高铁车站配套的地铁车站的施工会受到其他配套设施施工的相互干扰的技术问题。
