Description

Technical Field

[0001] The utility model relates to the technical field of foundation pits, in particular to a foundation pit safety protection device. Background Technique

[0002] A foundation pit is an earth pit excavated at the designed position of the foundation according to the base elevation and the foundation plane size. Before excavation, the excavation plan should be determined based on geological and hydrographic data, combined with the situation of nearby buildings on site, and waterproof and drainage work should be done well. For those with shallow excavation, the method of sloping the side can be used to stabilize the soil slope, and the slope size is determined according to relevant construction regulations. For those with deeper excavation and adjacent buildings, methods such as foundation pit wall support, shotcrete retaining wall method, and even methods such as diaphragm wall and column - type bored cast - in - place pile interlocking can be used for large - scale foundation pits to prevent the outer soil layer from collapsing; for those with no impact on nearby buildings, the well point method can be used to lower the groundwater level and open excavation with slope can be adopted; in cold regions, the natural cold air freezing method can be used for excavation, etc.

[0003] During the excavation and construction process of the foundation pit, protection will be carried out on the surrounding area. The existing foundation pit protection device is fixed by screws during the installation and disassembly process, resulting in very inconvenient installation and disassembly of the protection device. Moreover, the foundation pit protection device is a repeatedly used device. Therefore, when the foundation pit protection device is frequently used, the screws for installing and using the foundation pit protection device are prone to thread slipping problems, so that the foundation pit protection device cannot be used continuously.

[0004] A foundation pit safety protection device proposed according to the publication number: CN220686935U includes symmetrically arranged vertical rod 1 and vertical rod 2. Between the vertical rod 1 and the vertical rod 2, symmetrically arranged cross - bars are provided. Between the two groups of cross - bars, a number of uniformly distributed railings are provided. At the bottom ends of the vertical rod 1 and the vertical rod 2, bases are provided. Symmetrically arranged through - holes 1 are opened on the bases. Anchor rods matching the through - holes 1 are arranged in the through - holes 1. Three groups of uniformly distributed limiting plates are arranged around the outer wall of the anchor rods. The limiting plates are connected to the anchor rods through expansion components. Beneficial effects: Through the combined design of the cross - bars and the railings, a protection effect is formed. And through the combined design of the expansion components with the anchor rods and the limiting plates, after the anchor rods are inserted into the soil, the limiting plates are driven by the operation of the expansion components to move outward from the inside of the anchor rods, so that the limiting plates extrude the soil and increase the anchoring effect of the anchor rods, achieving the effect that the guardrail will not be easily knocked down.

[0005] According to the above introduction, the safety protection device used for the foundation pit cannot achieve the effect of quick installation and disassembly, and the problem of thread slipping occurs in the foundation pit safety protection device fixed by screws after a long time, so that the foundation pit safety protection device cannot be used continuously. To solve the above - mentioned problems, an improved foundation pit safety protection device is proposed. Content of the Utility Model
