Subway station foundation pit temporary component full-recovery supporting system and construction method
The invention discloses a subway station foundation pit temporary component full-recovery supporting system and a construction method, and belongs to the technical field of subway station foundation pit construction.The technical scheme is that the subway station foundation pit temporary component full-recovery supporting system comprises surrounding purlins and combined piles, the combined piles comprise steel pipe piles and steel sheet piles which are arranged in a staggered mode, and the steel sheet piles make contact with one side of a connecting component; and the other side of the connecting component is detachably connected with the enclosing purlin. The combined pile structure convenient to disassemble is adopted, and full recovery of temporary components can be achieved; and on the basis of the idea of deformation compensation, excavation deformation is predicted, combined pile small-angle construction is conducted, excavation deformation is compensated, investment is reduced, the construction period is shortened, and construction safety is improved.
本发明公开了一种地铁车站基坑临时构件全回收支护体系及施工方法，属于地铁车站基坑施工技术领域，其技术方案为：包括围檩、组合桩，所述组合桩包括交错布置的钢管桩和钢板桩，所述钢板桩与连接构件一侧相接触，连接构件另一侧与围檩可拆卸连接。本发明采用方便拆卸的组合桩结构，能够实现临时构件的全回收；且基于变形补偿的理念，预测开挖变形，组合桩小角度施工，补偿开挖变形，减少投资，节约工期，提高施工安全性。
