Description

Technical Field

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

[0002] The foundation pit refers to a deep pit or a large hole dug before construction to build the foundation of a building. The foundation pit support is a series of measures taken during the excavation of the foundation pit to prevent the collapse of the foundation pit slope and loose soil, and to ensure safety and stability during the construction process. When carrying out foundation pit support, the drainage structure is a very important part, which aims to effectively remove the accumulated water in the foundation pit, keep the foundation pit dry, and ensure the smooth progress of the construction.

[0003] After searching, the utility model with the publication number of "CN219157688U" provides "a drainage structure for foundation pit support, including a main body, the main body is inserted into the bottom surface of the foundation pit, and the upper surface of the main body is flush with the bottom surface of the foundation pit, the outer wall of the main body is fixedly equipped with a support ring, the outer wall of the circular frame is fitted with the inner wall of the main body, the circular frame is connected to the support ring through an adjustment structure, and the side wall of the main body is penetrated and connected with a drainage pipe, through the action of the filter screen, it is convenient to separate the water and the soil in the foundation pit to ensure the drainage effect, and at the same time fundamentally solve the problem of the drainage pipe being blocked by the suction of mud. The adjustment structure can adjust the circular frame to drive the filter screen and the sleeve to move longitudinally to avoid the mud soil and other covering the surface of the main body, and can drive the mud soil to move downward to form a slope, and through the seepage effect, filter the water into the main body for pumping, which is highly practical." However, in the actual drainage process, the mud in the water will adhere to the surface of the filter. When the adjustment structure drives the filter to move longitudinally, it is unable to effectively clean the mud attached to the surface of the filter. Long-term accumulation of mud will cause the filter to be completely blocked, and drainage work will be unable to continue.

[0004] Therefore, we provide a drainage structure for foundation pit support. Utility Model Content
