Foundation pit supporting structure capable of avoiding relocation and reformation of existing pipeline and construction method of foundation pit supporting structure
The invention discloses a foundation pit supporting structure capable of avoiding existing pipeline relocation and transformation and a construction method of the foundation pit supporting structure, and relates to the technical field of foundation pit excavation pipeline in-situ protection. The foundation pit supporting structure capable of avoiding relocation and reformation of the existing pipeline comprises a foundation pit enclosure structure, a top beam and a reverse wall structure, the foundation pit enclosure structure comprises two first underground diaphragm wall sections extending in the transverse direction, two second underground diaphragm wall sections extending in the transverse direction are arranged at the opposite ends of the two first underground diaphragm wall sections correspondingly, and the two second underground diaphragm wall sections are arranged on the two sides of the pipeline in the transverse direction at intervals; a receding opening is formed; the top beam is arranged at the upper end of the receding opening, the reverse wall structure is correspondingly arranged at the lower end of the top beam, the two transverse sides of the reverse wall structure are fixedly connected with the H-shaped steel joints of the two second underground diaphragm wall sections correspondingly, and the reverse wall is provided with a line passing opening penetrating in the longitudinal direction corresponding to the pipeline. The structural strength of the top beam is improved by arranging the second underground continuous wall section, the reverse wall structure is arranged below the top beam for layer-by-layer excavation, construction is simple, and existing pipelines cannot be damaged.
本发明公开一种可避免既有管线迁改的基坑支护结构及其施工方法，涉及基坑开挖管线原位保护的技术领域。可避免既有管线迁改的基坑支护结构包括基坑围挡结构、冠梁和逆做墙结构，基坑围挡结构包括沿横向延伸的两个第一地下连续墙段，其相对的一端分别设置有两个沿横向延伸的第二地下连续墙段，沿横向间隔设置于管线的两侧，以形成避让口；冠梁设于避让口的上端，逆做墙结构对应设置于冠梁的下端，逆做墙结构横向的两侧分别与两个第二地下连续墙段的H型钢接头固定连接，逆做墙对应管线设有沿纵向贯穿的过线口。通过设置第二地下连续墙段提高冠梁的结构强度，在冠梁下设置逆做墙结构逐层开挖，施工简单且不会损伤既有管线。
