Dismantling construction method for shared enclosure structure of subway station
The invention discloses a dismantling construction method for a shared enclosure structure of a subway station, and relates to the technical field of municipal engineering enclosure construction. According to the construction method, the whole foundation pit is divided into a plurality of areas according to the construction surface, then the areas are divided into a plurality of unit blocks, and the whole fender post structure needing to be dismantled is dismantled into blocks for construction; the dismantling method comprises the following steps: pouring a bottom plate I and arranging a temporary support; in the unit blocks without the temporary supports, the pile supports are dismantled, and a third bottom plate is arranged; and the pile supports of the other unit blocks are dismantled, a fourth bottom plate is arranged, all the temporary supports are dismantled, a fifth bottom plate is arranged, and then side walls and a top plate are constructed. According to the dismantling method, the temporary supports are arranged firstly, then the pile supports are dismantled in a segmented mode, and after the bottom plate is constructed, the side walls and the top plate are constructed. According to the dismantling method, firstly, the safety risk of the foundation pit is reduced; secondly, a dismantled object is convenient to hoist; and thirdly, the leakage risk caused by reverse construction of the structure is prevented.
本发明公开了一种地铁车站共用围护结构的拆除施工方法，涉及市政工程围护施工技术领域。本发明将整个基坑按照施工面划分为若干个区域，再将区域内划分为若干单元块，将整个需要拆除的围护桩结构，拆分为块再进行施工；拆除步骤为：浇筑底板一，设置临时支撑；在未设置有临时支撑的单元块中，拆除桩支撑，设置底板三；拆除其余单元块的桩支撑，设置底板四，并拆除所有临时支撑，设置底板五，再进行侧墙以及顶板的施工。此种拆除方法，为先设置临时支撑，再分段拆除桩支撑，底板施工后，再施工侧墙、顶板。这种拆除方法，一是降低了基坑的安全风险；二是便于吊运拆除物；三是防止了结构逆做的渗漏风险。
