Construction method of underground structure in foundation pit
The invention belongs to the technical field of foundation pit engineering construction, and discloses a construction method of an underground structure in a foundation pit, which comprises the following steps: firstly, assembling connecting pieces, and mounting the connecting pieces at two ends of each supporting piece; the two ends of the supporting piece are installed on the inner wall of the continuous wall through the connecting pieces, so that the continuous wall is stably supported, and deformation of the foundation pit is avoided. The bottom plate of the underground structure is poured at the bottom of the foundation pit, the lower-layer structure is poured to the designed elevation from the bottom plate at a time, the connecting piece is poured into the lining wall, by arranging the connecting piece, space is reserved for pouring of the lining wall, an operator can achieve pouring of the lower-layer structure without dismantling a supporting piece, the supporting changing step of a conventional technology is reduced, and the construction efficiency is improved. The side wall and the top plate of the lower-layer structure can be cast at a time, the construction period is shortened, the connecting pieces are reserved in the lining wall, and the strength of the wall body is further improved. And after the lower-layer structure reaches the design strength, the supporting pieces are dismantled, and therefore construction operation of the underground structure is completed in an ordered layering mode.
本发明属于基坑工程施工技术领域，公开了一种基坑内地下结构的施工方法，首先组装连接件，并在每个支撑件的两端安装连接件。支撑件的两端通过连接件安装于连续墙的内壁上，从而对连续墙进行稳定支撑，避免基坑变形。在基坑的底部浇筑地下结构的底板，自底板一次性浇筑下层结构至设计标高，并将连接件浇筑至内衬墙中，通过设置连接件，为内衬墙的浇筑预留了空间，使得作业人员无需拆除支撑件即可实现下层结构的浇筑，减少了常规工艺换撑步骤，可一次性浇筑完成下层结构侧墙及顶板，缩短施工周期，而且，连接件留存于内衬墙中，进一步提高了墙体强度。待下层结构达到设计强度后，拆除支撑件，从而有序分层完成地下结构的施工作业。
