TECHNICAL FIELD

[0001] The application relates to the technical field of foundation pit support, in particular to a support structure for foundation pit stability. BACKGROUND

[0002] Foundation pit support is a support, reinforcement and protection measure for the side wall and surrounding environment to ensure the safety of underground structure construction and the surrounding environment. With the rapid development of urban high-rise buildings, foundation pit support plays an important role in the construction of high-rise buildings, subway stations and other underground projects. Foundation pit support engineering usually involves complex surrounding environment, such as traffic arteries, existing buildings or pipelines, and therefore special attention should be paid to its safety and stability.

[0003] Since the support pile is placed, a support layer needs to be built between the support piles, and the support layers in the prior art are not connected but only supported by the support piles, and the stress effect is poor. Therefore, the application provides a support structure for foundation pit stability. CONTENT OF THE UTILITY MODEL

[0004] In view of the deficiencies of the prior art, the application aims to provide a support structure for foundation pit stability to solve the above technical problems.

[0005] The above-mentioned purpose of the application is achieved by the following technical scheme: a support structure for foundation pit stability, comprising a plurality of support layers, a connecting flange is fixed on one side of the support layer, a connecting groove matched with the connecting flange is formed on the other side of the support layer, a connecting piece is fixed on the support layer, a reinforcing piece is arranged close to the support layers, and the reinforcing piece is installed in the connecting piece.

[0006] By adopting the above technical scheme, when the support layer is installed, one support layer is attached to the side wall of the foundation pit, then the connecting flange on the second support layer is aligned with the connecting groove on the first support layer, so that the support layer and the support layer are abutted together, and then the reinforcing piece is installed in the connecting piece on the support layer, so that the support layer and the reinforcing piece present a triangular shape.

[0007] Further, connecting grooves are formed on both sides of the connecting piece, the reinforcing piece comprises a reinforcing layer plate, and the reinforcing layer plate is inserted into the connecting grooves on both sides.

[0008] By adopting the above technical scheme, when the reinforcing layer plate is installed, the reinforcing layer plate is inserted into the connecting pieces on both support layers by using a crane, so that the installation is completed.

[0009] Further, a flexible layer is arranged in the connecting groove and fixed on the support layer.

[0010] By adopting the technical scheme, the flexible layer is arranged in the connecting groove, so that the friction between the connecting flange and the connecting groove can be reduced when the supporting layers are built.

[0011] Further, the flexible layer is made of flexible rubber.

[0012] By adopting the technical scheme, the flexible rubber has low cost and good buffering effect, and is very suitable as a buffering material.

[0013] Further, the upper end of the supporting layer and the reinforcing layer plate is provided with a suspension device.

[0014] Further, the suspension device comprises a through hole formed in the upper end of the supporting layer and the reinforcing layer plate, a threaded cylinder fixedly arranged in the through hole, a threaded rod threadedly arranged in the threaded cylinder, and a lifting ring rotatably arranged at the upper end of the threaded rod.

[0015] By adopting the technical scheme, when the suspension is performed, the threaded rod is installed in the threaded cylinder, and then the lifting ring is buckled by a crane, so that the suspension is performed, the splicing construction is performed, and the construction can be completed and then the suspension device can be disassembled and recycled.

[0016] Further, the bottom of the supporting layer is fixedly provided with a support layer extending inward.

[0017] By adopting the technical scheme, the support layer is provided, and an additional support stress point is provided.

[0018] Further, the support layer is provided with a plug-in groove for plugging with the reinforcing layer plate.

[0019] By adopting the technical scheme, when the reinforcing layer plate is installed, the reinforcing layer plate can be directly plugged into the plug-in groove of the support layer, and the integration of the support layer and the reinforcing layer plate is improved.

[0020] In summary, the present application has the following beneficial technical effects:

[0021] Through the superposition and connection of multiple supporting layers, a whole stable supporting system is formed. The close connection between the supporting layers and the installation of the reinforcing members enable the whole supporting structure to effectively resist the deformation and displacement of the side wall of the foundation pit, thereby significantly improving the stability of the foundation pit.

[0022] The design of the supporting layer adopts the matching mode of the connecting flange and the connecting groove, so that the installation between the supporting layers becomes simple and fast. The construction personnel only need to align the connecting flange of one supporting layer with the connecting groove of another supporting layer, and then install the reinforcing member, which greatly reduces the installation time and labor cost.

[0023] The installation of the reinforcing member forms a stable triangular structure between the supporting layers and between the reinforcing members. The triangle is stable in mechanics, and therefore this design makes the supporting structure have stronger anti-deformation and load-bearing capacity. BRIEF DESCRIPTION OF DRAWINGS

[0026] The application will be further described in detail below with reference to the accompanying drawings.

[0027] Embodiment, refer to Figure 1 A supporting structure for the stability of a foundation pit comprises a plurality of groups of supporting layers 1, the supporting layers 1 are fixedly provided with connecting flanges 11 on one side, and connecting grooves 10 matching the connecting flanges 11 are formed on the other side, the supporting layers 1 are fixedly provided with connecting members 12, reinforcing members are arranged close to the supporting layers 1, and the reinforcing members are installed in the connecting members 12. When the supporting layers 1 are installed, a supporting layer 1 is attached to the side wall of the foundation pit, then the connecting flange 11 on the second supporting layer 1 is aligned with the connecting groove 10 on the first supporting layer 1, so that the supporting layer 1 and the supporting layer 1 are abutted together, then the reinforcing member is installed in the connecting member 12 on the supporting layer 1, so that the supporting layers 1 and the reinforcing members present a triangular shape.

[0028] In the embodiment, connecting grooves are formed on both sides of the connecting member 12, and the reinforcing member comprises a reinforcing layer plate 13, the reinforcing layer plate 13 is inserted into the connecting grooves on both sides. When the reinforcing layer plate 13 is installed, a crane is used to insert the reinforcing layer plate 13 into the connecting members 12 on the two supporting layers 1 at both ends, so as to complete the installation.

[0029] In the embodiment, the connecting groove 10 is internally provided with a flexible layer 101 fixedly connected to the supporting layer 1. By arranging the flexible layer 101 in the connecting groove 10, the friction between the connecting flange 11 and the connecting groove 10 can be reduced when the supporting layers 1 are built up.

[0030] In the embodiment, the flexible layer 101 is made of flexible rubber. The flexible rubber has low cost and good buffering effect, and is very suitable as a buffering material.

[0031] In this embodiment, the supporting layer 1 and the reinforcing layer plate 13 are provided with suspension devices at the upper ends. The suspension device includes a through hole opened at the upper end of the supporting layer 1 and the reinforcing layer plate 13, and a threaded cylinder 3 fixedly arranged in the through hole. A threaded rod 31 is threadedly arranged in the threaded cylinder 3, and a lifting ring 32 is rotatably arranged at the upper end of the threaded rod 31. When suspending, the threaded rod 31 is installed in the threaded cylinder 3, and then the lifting ring 32 is buckled by a crane, so that the supporting layer 1 and the reinforcing layer plate 13 are suspended and spliced.

[0032] In this embodiment, the supporting layer 1 is fixedly arranged with a support layer 2 extending inward at the bottom. The arrangement of the support layer 2 provides an additional support stress point.

[0033] In this embodiment, the support layer 2 is provided with a plug-in groove 21 for plugging with the reinforcing layer plate 13. When installing the reinforcing layer plate 13, it can be directly plugged into the plug-in groove 21 on the support layer 2, improving the integrity of the support layer 2 and the reinforcing layer plate 13.

[0034] Specific implementation process: First, the supporting structure adopts the design of multiple supporting layers 1, which are tightly connected through the matching of the connecting flanges 11 and the connecting grooves 10. This design not only improves the overall stability of the supporting structure, but also helps to reduce the deformation and displacement of the side wall of the foundation pit. At the same time, the matching mode of the connecting flanges 11 and the connecting grooves 10 makes the installation and disassembly of the supporting layer 1 more convenient and fast.

[0035] Secondly, the introduction of the reinforcing member further enhances the strength and stability of the supporting structure. The reinforcing member is installed in the connecting groove in the connecting member 12, forming a stable triangular structure with the supporting layer 1. This structure is very stable in mechanics and can effectively resist external pressure and deformation. In addition, the design of the reinforcing layer plate 13 inserted into the connecting groove on both sides makes the installation and disassembly of the reinforcing member more convenient.

[0036] Furthermore, the flexible layer 101 arranged inside the connecting groove 10 plays a good buffering role. The flexible layer 101 is made of flexible rubber, which has the advantages of low cost and good buffering effect. It can reduce the friction between the connecting flanges 11 and the connecting grooves 10 when the supporting layers 1 are built, protect the supporting layers 1 from damage, and improve the overall stability and durability of the supporting structure.

[0037] In addition, the suspension devices arranged at the upper ends of the supporting layer 1 and the reinforcing layer plate 13 also bring convenience to the construction. Through the suspension device, the supporting layer 1 and the reinforcing layer plate 13 can be conveniently suspended and spliced by the crane, greatly improving the construction efficiency and quality. At the same time, the design of the suspension device makes the supporting structure more safe and reliable during installation and disassembly.

[0038] Finally, the support layer 2 fixedly arranged at the bottom of the supporting layer 1 inwardly provides an additional support stress point for the supporting structure. The insertion slots 21 arranged on the support layer 2 can also be inserted with the reinforcing layer plates 13, further improving the integrity of the support layer 2 and the reinforcing layer plates 13. This design not only enhances the overall stability of the supporting structure, but also helps to improve the load-bearing capacity of the side wall of the foundation pit.

[0039] The embodiments of the present specific implementation are the preferred embodiments of the present application, and are not intended to limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
