Description

Technical Field

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

[0002] Foundation pit refers to the space below the ground excavated for the construction of underground structures during the construction process. In order to prevent the soil around the foundation pit from shifting and collapsing due to unbalanced force and to ensure the safety of the underground structure and the surrounding environment, support devices are often installed inside the foundation pit to ensure safety and stability during the excavation process.

[0003] Most of the existing support devices are continuous support plates fixedly installed around the foundation pit. They bear the lateral pressure from the pit wall soil, forming a stable three-dimensional force system to support and block the soil, prevent the soil from falling and collapsing, and ensure the safe and smooth progress of the project.

[0004] In actual use of the prior art, the soil in the foundation pit after excavation will slide downward, resulting in a certain slope around the foundation pit. When the support plate is fixedly installed, there will be a certain angle gap between it and the edge of the foundation pit, which weakens the effective effect of the support structure and cannot effectively disperse and transfer the pressure of the soil. Therefore, a foundation pit support device is proposed. Utility Model Content

[0029] Example 2

[0030] Reference Figure 1 , Figure 2 and Figure 3 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment, and a support mechanism 3 is provided on one side of the support plate 101;

[0031] The supporting mechanism 3 comprises a connecting plate 301 fixedly connected to one side of the supporting plate 101, a mounting rod 303 is inserted into the inner cavity of the connecting plate 301, a round handle 2 304 is fixedly connected to one end of the mounting rod 303, a connecting block 302 is sleeved on the outer surface of the mounting rod 303, a spring 2 305 is sleeved on the outer surface of the mounting rod 303, a sleeve rod 2 306 is fixedly connected to one side of the connecting block 302, an adjusting rod 2 307 is movably connected to the inner cavity of the sleeve rod 2 306, a socket 2 308 is provided on the outer surface of the adjusting rod 2 307, a fixing frame 2 309 is fixedly connected to the outer surface of the sleeve rod 2 306, a plug rod 2 310 is inserted into the inner cavity of the fixing frame 2 309, and a spring 312 is sleeved on the outer surface of the plug rod 2 310;
