Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit protection, in particular to a foundation pit protection component. Background Art

[0002] The foundation pit is a pit dug at the design location of the foundation according to the base elevation and the plane size of the foundation. Before excavation, the excavation plan should be determined based on the geological and hydrological data and the situation of nearby buildings on site, and waterproofing and drainage should be done. If the excavation is not deep, the slope can be used to stabilize the slope, and the slope size is determined according to the relevant construction project regulations. For deep excavations and nearby buildings, the foundation pit wall support method and shotcrete wall protection method can be used. Large foundation pits can even use underground continuous walls and column-type bored pile interlocking methods to prevent the outer soil layer from collapsing; if there is no impact on nearby buildings, the well point method can be used to lower the groundwater level and use slope open excavation; in cold areas, natural cold air freezing method can be used for excavation, etc.

[0003] After searching, a patent with publication number CN220225333U discloses a foundation pit protection component, including a baffle, a fixing ring is fixed on the front surface of the baffle, a fixing rod is inserted inside the fixing ring, storage grooves are provided at both ends of the fixing rod, and the internal movable part of the storage groove is connected to the pin, and two movable openings are provided on the outer wall of the fixing rod, and the pin, baffle, fixing rod, external threaded tube, internal threaded tube, round rod and fixing ring are provided. The fixing rod is inserted into the fixing ring, and then the round rod is knocked with a hammer to insert the pin into the inner wall of the foundation pit. In this way, the baffle can be fixed to the inner wall of the foundation pit to protect the foundation pit. If the foundation pit is large, the rotating drum is rotated to rotate with the external threaded tube to connect the external threaded tube with the internal threaded tube on another fixing rod. In this way, multiple baffles can be connected together to protect the foundation pit.

[0004] The existing equipment is plugged into the inner wall of the foundation pit, but there is no force to reinforce and press down, which will cause the equipment to be loosely fixed, fall off, or be misplaced. Therefore, we propose a foundation pit protection component to solve the above problems. Utility Model Content
