Telescopic deep foundation pit supporting structure
The telescopic deep foundation pit supporting structure comprises a foundation pit and supporting plates, the supporting plates are arranged on the inner side wall of the foundation pit, a waterproof curtain is arranged in a soil body on the outer side of the foundation pit, and pre-stressed anchor rods are obliquely arranged along the edges of the supporting plates; the supporting plate comprises a transverse supporting panel used for being inserted into the pit wall and a vertical supporting panel used for being tightly attached to the pit wall, and the transverse supporting panel and the vertical supporting panel share the same edge. The transverse supporting panel is composed of at least two layers of movable panels which are sequentially nested, and every two adjacent layers of movable panels are connected in a sliding mode. And small holes for water permeation and stress concentration reduction are formed in the vertical supporting panel. According to the device, the collapse resistance of the side wall of the foundation pit is improved by utilizing the gravity of a soil body and using the telescopic supporting plate, and the supporting effect on the foundation pit is achieved. The supporting plates are connected into a whole through bolts, and the integrity and stability of the mechanism are improved. The detachable supporting structure reduces the influence of construction on the environment and the construction cost of a project.
本发明公开了一种伸缩式深基坑支护结构，包括基坑和支护板，基坑的内侧壁设置若干支护板，基坑的外侧土体中设置止水帷幕，沿所述支护板的边缘斜向设置预应力锚杆；所述支护板包括用于插入坑壁的横向支撑面板和用于贴紧坑壁的竖向支撑面板，横向支撑面板和竖向支撑面板存在一共边；所述横向支撑面板由至少两层依次嵌套的移动面板组成，相邻两层移动面板可滑动连接。竖向支撑面板上设有用于透水和减少应力集中的小孔。本装置利用土体自身重力，通过使用可伸缩的支护板，提高基坑侧壁的抗坍塌能力，实现对基坑的支护效果。支护板之间通过螺栓连接成整体，机构的整体性和稳定性提高。可拆卸式的支护结构降低了施工对环境的影响和工程的造价成本。
