Anchoring structure for supporting deep foundation pit and construction method of anchoring structure
The invention relates to an anchoring structure for supporting a deep foundation pit and a construction method of the anchoring structure. The anchoring structure comprises a supporting pile, a waist beam, an anchor cable body and a vacuum assembly. The anchor cable body penetrates through a soil body on the side wall of the foundation pit; the vacuum assembly is arranged in a foundation pit side wall soil body and comprises a plurality of exhaust pipes, a horizontal pipe network and a sealing film. The exhaust pipe is inserted into the foundation pit side wall soil body, the horizontal pipe network is arranged on the surface of the foundation pit side wall soil body, the drainage pipe is communicated with the horizontal pipe network, the sealing film is laid on the horizontal pipe network, and the horizontal pipe network is communicated with the vacuum system. According to the method, a worker carries out air extraction operation on the foundation pit side wall soil body through an external vacuum system and a vacuum assembly, so that the air pressure in the foundation pit side wall soil body is lower than the atmospheric pressure; and the atmospheric pressure acting force can be used for resisting the lateral pressure effect of a soil body on the side wall of the foundation pit, so that the design number of anchor cable bodies is reduced, and the construction period of a project is shortened.
本申请涉及一种深基坑支护用的锚固结构及其施工方法，包括支护桩、腰梁、锚索体和真空组件；锚索体穿设于基坑侧壁土体；真空组件设置于基坑侧壁土体中，真空组件包括若干根排气管、水平管网和密封膜；排气管插接于基坑侧壁土体中，水平管网设置于基坑侧壁土体表面，排水管与水平管网相连通，密封膜铺设于水平管网上，且水平管网与真空系统相连通。在本申请中，工作人员通过外部的真空系统与真空组件对基坑侧壁土体进行抽气操作，以使基坑侧壁土体内的气压低于大气压；从而使基坑侧壁受到大气压力差的作用，上述的大气压作用力可用于抵挡基坑侧壁土体的侧压力作用，从而减少锚索体的设计数量，缩短了项目的建设周期。
