Description

Technical Field

[0001] The present application relates to the field of civil engineering technology, and more specifically, to a foundation pit slope protection support device. Background Art

[0002] With the development of society, engineering structures are becoming larger and more complex. Super high-rise buildings, extra-large bridges, giant dams, and complex subway systems continue to emerge to meet people's living needs. At the same time, they have also evolved into a symbol of social strength. In civil engineering construction, foundation pits need to be protected. 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] The document with the prior art publication number CN113266018B provides a foundation pit slope reinforcement device for civil engineering. The device drives the first threaded column to rotate by rotating the motor inside the support column. When the first threaded column rotates, it will drive the first threaded block to move. When the first threaded block moves, it will drive the first connecting column to change the angle between it and the support column. In this way, the first connecting column will drive the rotating column to move through the pin block and the sliding block when it moves, and the rotating column will rotate around the first fixed column when it rotates until the rotating column can be connected to the limiting ring block, so that the first reinforcement plate and the second reinforcement plate can achieve the effect of reinforcing the slope.

[0004] Although the above-mentioned prior art solutions can achieve the relevant beneficial effects through the structure of the prior art, the above-mentioned reinforcement device is affected by the size of the reinforcement plate. When the foundation pit slope protection is long, it is necessary to set up multiple sets of the above-mentioned reinforcement devices for continuous support, resulting in high support costs and difficulty in support installation. In view of this, we propose a foundation pit slope protection support device. Utility Model Content
