[0002] A deep foundation pit refers to an excavation depth of more than 5 meters (including 5 meters) or more than three basement floors (including three floors), or a project with a depth of less than 5 meters but particularly complex geological conditions, surrounding environment and underground pipelines. Therefore, foundation pit support is a support, reinforcement and protection measure for the side walls of the foundation pit and the surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit.

[0003] Chinese patent number CN202321745911.8 discloses a deep foundation pit support device, including fixed columns, protective plates, anchor cables and reinforcement mechanisms. The left part of the protective plate is connected to multiple fixed columns, the upper and lower parts of the protective plate are clamped with multiple anchor cables, and the right side of the protective plate is provided with a reinforcement mechanism for increasing the protective performance of the protective plate.

[0004] From the above, it can be seen that by installing the protective plate through fixed columns and anchor cables, and then installing and connecting the concrete wall through plug plates and adjusting connecting rods, it is possible to achieve the effect of quickly supporting the deep foundation pit and recycling it. However, this case still has the following shortcomings: when using the support device for the deep foundation pit, the support cannot be moved during the support work. When adjustment and movement are required, the overall fixation needs to be dismantled and then re-fixed, resulting in low efficiency when adjustment is required and increased labor intensity of personnel.

[0005] Therefore, a deep foundation pit supporting device is proposed to solve the above problems. Utility Model Content
