Foundation pit horizontal support and vertical inclined support combined supporting structure and construction method
The invention discloses a foundation pit horizontal support and vertical inclined support combined supporting structure and a construction method. The construction method comprises the steps that 1, a vertical inclined support is obliquely driven into a second supporting position in a soil body through a pile feeder; 2, grouting to form a fixed pile structure, and pulling out a grouting pipe; 3, pulling out the pile feeder, and backfilling the flow-state solidified soil; 4, constructing an enclosure structure; 5, constructing a horizontal support at the position of the first support; 6, excavating earth below the horizontal support; 7, excavating to the position of a second support, constructing a waist beam at the position of the second support, and connecting the waist beam with the head of the vertical inclined strut and the enclosure structure; 8, continuously excavating, and constructing a bottom plate; 9, the vertical inclined struts above the bottom plate are cut off, and the underground structure continues to be constructed; and 10, the horizontal support is dismantled, and construction of the underground structure is completed. The invention relates to the technical field of building foundation pit construction, and can solve the problems that in the prior art, when a second steel pipe inclined throwing support is constructed, procedures are complex, cross operation is much, and earth excavation is difficult.
本发明公开了一种基坑水平撑与竖向斜撑的组合支护结构及施工方法，该施工方法包括步骤：1、将竖向斜撑通过送桩器斜向打入土体内的第二道支撑位置处；2、注浆形成固定桩结构，拔出注浆管；3、拔出送桩器，回填流态固化土；4、施工围护结构；5、在第一道支撑位置处施工水平撑；6、水平撑下方的土方开挖；7、开挖至第二道支撑位置处，施工第二道支撑位置处的腰梁并与竖向斜撑的头部和围护结构连接；8、继续开挖，施工底板；9、割除底板上方的竖向斜撑，继续施工地下结构；10、拆除水平撑，完成地下结构的施工。本发明涉及建筑基坑施工技术领域，能解决现有技术中第二道钢管斜抛撑施工时工序复杂、交叉作业多、土方开挖困难的问题。
