Detachable assembly type foundation pit temporary supporting device, supporting structure and construction method
The invention discloses a detachable assembly type foundation pit temporary supporting device, a supporting structure and a construction method, and relates to the technical field of building construction. The supporting device comprises an upper guide cross beam and a lower guide cross beam which are arranged from top to bottom, a plurality of reinforcing piles are arranged at the corresponding positions of the upper guide cross beam and the lower guide cross beam in a penetrating mode respectively, inclined strut supports are arranged on the adjacent reinforcing piles, and dense-mesh steel meshes are arranged for soil blocking, so that rapid mounting and dismounting can be achieved, rigid protection and flexible protection are both considered, and the supporting effect is good. The soil slope is allowed to have certain deformation, and the stress of the supporting structure is more comprehensive and reasonable. The device is simple and practical in structure, can quickly perform safety protection on small and medium-sized foundation pits in a construction site, can be disassembled and recycled, meets quick turnover of the construction site, accelerates the field supporting operation efficiency and protection speed, reduces foundation pit collapse safety accidents and reduces temporary operation protection cost, and has certain economic benefits.
本发明公开了一种可拆卸装配式基坑临时支护装置、支护结构及施工方法，涉及建筑施工技术领域。本支护装置包括由上而下设置的上导向横梁和下导向横梁，所述上导向横梁和下导向横梁相对应位置分别穿设有若干加强桩柱，通过在相邻加强桩柱上设置斜撑支架且布设密目钢网挡土，可实现快速安装及拆卸，兼顾刚性和柔性防护，允许土坡有一定变形量，支护结构受力也更为综合合理。本发明装置结构简单实用，可针对施工现场中小型基坑快速进行安全防护，并且可以进行拆卸重复周转利用，满足施工现场的快速周转，加快现场支护作业效率和防护速度，减少基坑坍塌安全事故，降低临时作业防护成本，具有一定经济效益。
