The invention relates to a foundation pit support structure firmly connected with the side wall of the foundation pit, which includes a plurality of bottom plates and a plurality of guard plates, and the two ends of the top of each bottom plate are respectively vertically fixed with connection plates, and the two The opposite inner side of the connecting plate is provided with a first slot respectively, the two ends of the guard plate are fixedly connected with a plug-in board respectively, and the two plug-in boards are plugged into the two first slots respectively; the connecting board and A lead screw is screwed on the guard plate, one end of each lead screw is affixed with a drill bit, and the other end is affixed with a rotating part; each end of the lead screw away from the drill bit is provided with a mounting groove, and the mounting groove Through holes are respectively opened on both sides of the installation groove, and a limit device is installed in the installation groove. A drive mechanism that moves blocks toward or away from each other. The invention can make the support structure more firmly connected with the side wall of the foundation pit.
Description
technical field [0001] The invention relates to the technical field of foundation pit support, in particular to a foundation pit support structure firmly connected with the side wall of the foundation pit. Background technique [0002] During the excavation of the foundation pit, the surrounding soil will inevitably be deformed, which will affect the underground pipelines of the surrounding buildings, and seriously endanger the normal use and safety of the underground pipelines. In order to avoid this situation, a foundation pit support structure will be set up in the foundation pit design and excavation construction to stabilize the safety of the foundation pit. [0003] The prior art can refer to the Chinese invention patent application document with publication number CN108166506A, which discloses a foundation pit support structure, including a plurality of support components arranged along the side walls of the foundation pit, and the support components include The base...
