Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support, in particular to a deep foundation pit support structure. Background Technique

[0002] Deep foundation pit support refers to a deep foundation pit with a certain depth of the construction building. To prevent the collapse of the pit wall and soil settlement, support measures need to be taken to ensure construction safety and building stability. The design of the deep foundation pit retaining structure includes determining the shape, depth and required bearing capacity of the foundation pit, and designing a reliable and effective retaining structure. This process needs to consider multiple factors such as soil, water level, environment, etc. to ensure that the retaining structure can safely withstand the required external and internal forces.

[0003] After retrieval, the Chinese patent publication number: CN217204129U, discloses a deep foundation pit support structure including a support plate and an inclined support column. The inclined support column is fixedly installed on one side of the support plate. A rotating shaft is fixedly installed inside the inclined support column. One side of the rotating shaft is hinged with a pressing block. One side of the pressing block is welded with a movable column. One side of the movable column is fixedly connected with a movable block. There is a movable plate on one side of the movable block. A through groove is opened inside the movable plate, and the movable block is slidably connected inside the through groove of the movable plate. A limiting block is inserted at the bottom of the movable plate. There is a soil-breaking head on one side of the limiting block. A movable rod is fixedly installed on the side of the limiting block away from the soil-breaking head. Although this patented technology solves the problem that the traditional support structure cannot support and protect the foundation pit during landslide collapse by setting a pressing block and a movable block, when the foundation pit collapses, the support plate drives the inclined support column to move, and finally the limiting block is inserted into the soil to increase the support area.

[0004] However, when supporting the foundation pit, support plates of different lengths need to be used for foundation pits of different depths, which has low flexibility, poor applicability, and poor support strength, and is likely to cause the collapse of the foundation pit edge, posing a safety hazard. Therefore, those skilled in the art provide a deep foundation pit support structure to solve the problems raised in the above background technique. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a deep foundation pit support structure, aiming to improve the problems in the prior art that support plates of different lengths need to be used for foundation pits of different depths, with low flexibility, poor applicability, poor support strength, and easy collapse of the foundation pit edge, posing a safety hazard.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] A deep foundation pit support structure includes a support plate. On both the front and rear sides of the left side inside the support plate, moving grooves are provided.

Inside the first rotating seat, a support component is rotatably connected.

[0012] Through the above technical solution, pulling the pulling block drives the connecting rod to move the plug, squeezes the second spring and moves it into the connecting cylinder to separate from the cross-shaped block. By pushing the first rotating seat up or down, it moves inside the cross-shaped groove, so that the telescopic rod rotates inside the first rotating seat and the second rotating seat, adjusts the position of the first rotating seat, and improves the support strength of the support plate.

[0013] Further, the support component includes a telescopic rod. The telescopic rod is rotatably connected inside the first rotating seat. On the outer side of one end of the telescopic rod, a second rotating seat is rotatably connected. At the bottom of the second rotating seat, a bottom plate is fixedly connected.

[0014] Through the above technical solutions, the support strength of the support plate is ensured.

[0015] Further, uniformly distributed jacks are provided on the front and rear sides of the support plate, and the connecting cylinder is slidably connected inside the jacks.
