Foundation pit inclined strut supporting structure and construction method
The invention discloses a foundation pit inclined strut supporting structure and a construction method.The foundation pit inclined strut supporting structure comprises a foundation pit fender post, a counter-force device, an inclined pile composite support and a horizontal bearing force loading device, the foundation pit fender post is arranged in the vertical direction, and the counter-force device is arranged at the top of the foundation pit fender post and connected with one end of the horizontal bearing force loading device; the inclined pile composite support is connected with the other end of the horizontal bearing force loading device and forms a certain included angle with the foundation pit fender post; after the foundation pit is excavated to the bottom elevation and before the inclined pile composite support is dismantled, the horizontal bearing capacity loading device is used for monitoring the horizontal displacement of the top of the inclined pile composite support under the horizontal pressure, the load displacement curve of the inclined pile composite support is obtained, and therefore the horizontal bearing capacity of the inclined pile composite support is determined; and finally, the construction quality of each inclined pile composite support is ensured according to a pile test report. Meanwhile, the horizontal bearing force loading device is flexible to disassemble and can be recycled; the invention further discloses a construction method of the foundation pit inclined strut supporting structure.
本申请公开了一种基坑斜撑支护结构及施工方法，基坑斜撑支护结构包括基坑围护桩、反力装置、斜桩复合支撑及水平承载力加载装置，基坑围护桩沿竖直方向设置，反力装置设置于其顶部并与水平承载力加载装置的一端连接，斜桩复合支撑与水平承载力加载装置的另一端连接并与所述基坑围护桩成一定夹角；本申请在基坑开挖到底部标高后，斜桩复合支撑拆除之前，借助水平承载力加载装置在水平压力下监测斜桩复合支撑顶部的水平位移，得到斜桩复合支撑的荷载位移曲线，从而确定斜桩复合支撑的水平承载力，最终根据试桩报告确保各根斜桩复合支撑的施工质量；同时水平承载力加载装置拆卸灵活，可以回收使用；本申请还公布了上述基坑斜撑支护结构施工方法。
