Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support structures, in particular to a support structure for foundation pit support that can be recycled. Background Technique

[0002] The type and selection of foundation pit support structures are important contents in geotechnical engineering, which are directly related to the safety, economy and environmental impact of the project. In response to the requirement that the foundation pit support structure can be recycled, in order to effectively control the deformation of the foundation pit and protect the surrounding environment, the construction and support of the foundation pit project are the key links to ensure the safety and stability of the building. The commonly used temporary retaining, reinforcement, protection and groundwater control measures for the in - support foundation pit can effectively reinforce the side wall during the foundation pit excavation and protect the safety of the underground main structure construction and the surrounding environment of the foundation pit. The foundation pit support structure is mainly used for temporary support of the foundation pit, which means that during the earth excavation process, in order to ensure the safety and stability of surrounding buildings, roads and underground pipelines, various support forms are used to reinforce and support the pit wall.

[0003] In the existing situation, rainwater infiltration during rainy weather will cause an increase in the saturation of the soil around the foundation pit. When the soil changes from an unsaturated state to a saturated state, its internal friction force decreases and its cohesion weakens, thus greatly reducing the overall shear strength of the soil. Therefore, a support structure that can improve the stability of the support structure is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a support structure for foundation pit support that can be recycled, so as to solve the problem proposed in the above - mentioned background technique that rainwater infiltration during rainy weather will cause an increase in the saturation of the soil around the foundation pit. When the soil changes from an unsaturated state to a saturated state, its internal friction force decreases and its cohesion weakens, thus greatly reducing the overall shear strength of the soil.

[0034] To make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0035] Please refer to Figures 1 - 5 As shown, this embodiment is a support structure for foundation pit support that can be recycled, including:

[0036] A guard plate 11;

[0037] A support assembly, which includes a mounting frame 21, a chassis 22, a first electric push rod 23, a connecting plate 24, and a support block 241;

[0038] The mounting frame 21 is installed at the center inside the guard plate 11. The chassis 22 is fixedly connected to the middle part of the lower surface of the mounting frame 21. The first electric push rod 23 is installed on one side inside the mounting frame 21. The connecting plate 24 is connected to the output end of the first electric push rod 23. The support block 241 is fixedly connected to the middle part of the outer surface of the connecting plate 24;

[0039] The mounting frame 21 provides a physical connection point for the first electric push rod 23 and other components, and also ensures the symmetry and central balance of the entire support system, thereby ensuring the stability and effective operation of the entire assembly. The connecting plate 24 is connected to the output end of the first electric push rod 23, and its main function is to transmit the power of the push rod to the support block 241. The support block 241 is fixed in the middle of the outer surface of the connecting plate 24, improving the support stability of the guard plate 11 and ensuring that the pressure can be evenly distributed when force is applied, avoiding damage caused by excessive local stress;

[0040] A fixing tube 25 penetrates through the lower end of the outer surface of the guard plate 11. A circular hole 26 is opened at one end of the outer surface of the fixing tube 25. A clamping column 27 penetrates through the circular hole 26. A movable column 28 penetrates through the fixing tube 25. A second electric push rod 29 is installed on one side inside the chassis 22;

[0041] The fixed tube 25 provides a physical channel and positioning guarantee for the clamping post 27 and the movable post 28. This design of the fixed tube 25 ensures that the clamping post 27 and the movable post 28 can move within a stable and preset path;

[0042] The second electric push rod 29 provides additional power support and fine control ability, pushing the movable post 28 to move inside the fixed tube 25, extending the clamping post 27 out of the fixed tube 25 and clamping it into the soil;

[0043] Working principle:

[0044] When the foundation pit is being supported;

[0045] First, the staff first installs the guard plate 11 on the four walls of the foundation pit. Then, the installation frame 21 is installed in the middle of one side inside the foundation pit. Through the external controller, the controller controls the first electric push rod 23 to extend;

[0046] At this time, the first electric push rod 23 drives the connecting plate 24 to move to both sides, making the support block 241 contact the inside of the guard plate 11. And the connecting plate 24 synchronously drives the fixed tube 25 to move outward, penetrate the guard plate 11, and the fixed tube 25 is embedded inside the soil;

[0047] Then, through the external controller again, the controller controls the second electric push rod 29 to extend. The second electric push rod 29 extends and contacts the movable post 28, pushing the movable post 28 outward. The outer end of the movable post 28 is sloped. When the movable post 28 contacts the clamping post 27, the clamping post 27 is pushed outwards from the circular hole 26 and clamped into the soil inside;

[0048] Further improve the supporting force of the guard plate 11;

[0049] This step has strong adaptability. The designs of the support block 241 and the clamping post 27 ensure that stable support can be provided even in complex soil conditions.

[0050] Please refer to Figure 6 As shown, based on the above-mentioned Embodiment 1, this embodiment further includes:

[0051] Fixing components;

[0052] The fixing components include a limiting rod 31, a limiting groove 32, a fixing hole 33 and a threaded rod 34;

[0053] The limiting rod 31 is fixed at the center of one side of the outer surface of the guard plate 11. The limiting groove 32 is opened in the middle of one side of the outer surface of the installation frame 21. The fixing hole 33 is opened at the center of the other side of the outer surface of the installation frame 21. The threaded rod 34 penetrates inside the fixing hole 33;

[0054] The limiting rod 31 provides physical restraint to prevent the mounting frame 21 from shifting or rotating during use, enhancing the structural stability of the entire support assembly. The threaded rod 34 provides reliable mechanical locking, thus tightly connecting the guard plate 11 and the mounting frame 21. By rotating the threaded rod 34, precise tension adjustment can be achieved through the cooperation between its thread and the internal threaded hole. This not only facilitates the operator to adjust the tightness of the connection as needed but also ensures reliability and safety during long-term use.

[0055] Working principle:

[0056] When fixing the mounting frame 21;

[0057] First, the staff only needs to align the limiting groove 32 with the limiting rod 31 and snap it onto the outer surface of the limiting rod 31;

[0058] Then, screw the threaded rod 34 into the fixing hole 33. The threaded rod 34 passes through the fixing hole 33, the limiting groove 32 and the limiting rod 31 to fix the position of the mounting frame 21;

[0059] It is convenient for disassembly and reuse. The design of the threaded rod 34 and the limiting groove 32 is not only convenient for initial installation but also for subsequent disassembly;

[0060] This step can be reused among multiple projects, reducing long-term costs and construction waste.
