[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5A foundation pit support structure for cement-soil mixing walls includes several support rods 1. L-shaped mounting plates 2 are fixedly connected to the surface of each support rod 1. A fixing frame 3 is bolted between adjacent mounting plates 2. During use, the support rods 1 are fixed to the fixing frames 3 via the mounting plates 2, thus fixing the fixing frames 3 onto the support rods 1. This improves the stability of the support structure by connecting multiple supports through the fixing frames 3, enabling more stable support. An inclined plate 4 is fixedly connected to the surface of the fixing frame 3. The inclined plate 4 has several mounting grooves 5. During use, abutment rods 8 can be inserted through the mounting grooves 5 on the inclined plate 4, allowing the abutment rods 8 to provide stable support for the support rods 1, ensuring stability. Furthermore, during the support process, the abutment rods 8 can be... Several mounting slots 5 facilitate adjustment, allowing the abutment rod 8 to be used more effectively. During use, the tilting plate 4 can determine the support angle of the abutment rod 8, eliminating the need for angle adjustment and saving installation time. A stabilizing block 6 is fixedly connected inside the mounting slot 5. The surface of the stabilizing block 6 is equipped with the abutment rod 8 via the mounting mechanism 7. When the abutment rod 8 is needed, it can be inserted into the stabilizing block 6 and then passed through the fixing frame 3. During this process, the abutment rod 8 can be fixed inside the stabilizing block 6 by the mounting mechanism 7, enabling the abutment rod 8 to support and stabilize the fixing frame 3, thereby ensuring the stable use of the support rod 1. The abutment rod 8 passes between two adjacent support rods 1. When the abutment rod 8 is installed in different mounting slots 5, it must pass between two support rods 1.

[0024] Furthermore, the installation mechanism 7 includes an anti-movement rod 701 that passes through the surface of the stabilizing block 6. The anti-movement rod 701 passes through the surface of the abutment rod 8. When it is necessary to fix the abutment rod 8 to the stabilizing block 6, the abutment rod 8 can be passed through the installation groove 5 first, and then the anti-movement rod 701 can be moved so that the anti-movement rod 701 can enter the interior of the abutment rod 8 and restrict the abutment rod 8 to the surface of the stabilizing block 6. When it is not needed, the anti-movement rod 701 can be moved to pull out the abutment rod 8 so that the abutment rod 8 is not restricted by the stabilizing block 6, thereby pulling out the abutment rod 8 for disassembly.

[0025] Furthermore, an anti-movement plate 702 is fixedly connected to the surface of the stabilizing block 6, and a screw 703 is threadedly connected to the surface of the anti-movement plate 702. One end of the screw 703 passes through the surface of the anti-movement rod 701. Before the abutment rod 8 is inserted into the stabilizing block 6, the screw 703 on the anti-movement plate 702 needs to be rotated so that the screw 703 can disengage from the anti-movement rod 701. Then, the anti-movement rod 701 is pulled away from the stabilizing block 6, and the abutment rod 8 is inserted into the mounting groove 5. This process requires passing through the stabilizing block 6. After the abutment rod 8 is inserted, the anti-movement rod 701 is moved, and the anti-movement rod 701 passes through the abutment rod 8. Then, the screw 703 is rotated so that it can enter the interior of the anti-movement rod 701, thereby fixing the position of the anti-movement rod 701. This allows the anti-movement rod 701 to stably restrict the abutment rod 8, ensuring the normal use of the abutment rod 8.

[0026] Furthermore, auxiliary plates 9 are fixedly connected to both sides of the fixed frame 3, and adjacent auxiliary plates 9 are fixedly connected by bolts. Several insertion tubes 10 are fixedly connected inside the fixed frame 3, and the abutting rod 8 is located inside the adjacent insertion tube 10. When using the fixed frame 3 to stabilize the abutting rod 8, several fixed frames 3 can be interconnected through the auxiliary plates 9, so that the stability between several support rods 1 is improved. During use, the support rod 1 can cooperate with several mutually fixed fixed frames 3 to obtain stronger stability. The insertion tubes 10 can increase the stability of the abutting rod 8 and prevent the abutting rod 8 from shaking.

[0027] Furthermore, a ground spike 14 is fixedly connected to one end of the abutment rod 8, and two grips 15 are fixedly connected to the surface of the abutment rod 8. The ground spike 14 can easily insert the abutment rod 8 into the ground for stability, and the grips 15 can easily apply force to the abutment rod 8 for use.

[0028] Furthermore, the support rod 1 has an H-shaped cross-section, and several H-shaped reinforcing plates 11 are slidably connected between two support rods 1. Two L-shaped auxiliary rods 12 are fixedly connected to the surface of the support rod 1, and an H-shaped support rod 13 is slidably connected after the two auxiliary rods 12. When using the support rod 1 for support, the reinforcing plates 11 can increase the strength between the support rods 1, which can better support and protect them. Moreover, the cooperation between the auxiliary rods 12 and the support rods 13 can improve the support effect of the support rod 1, reduce the need for special equipment and connections, and better support can be provided.

[0029] In summary:

[0030] When supporting a foundation pit for a cement-soil mixing wall, the support rods 1 are first placed, and then several reinforcing plates 11 are placed between two adjacent support rods 1. During this process, support rods 13 are placed between auxiliary rods 12 to improve the support effect of the support rods 1. Then, the fixing frame 3 is fixed to the mounting plate 2 on the support rod 1. Adjacent fixing frames 3 can be connected to each other by auxiliary plates 9 and bolts to improve the stability of the support rods 1. In use, the abutment rod 8 is inserted into the stabilizing block 6 inside the mounting groove 5. The abutment rod 8 is angled with the inclined plate 4 through the insertion tube 10 to facilitate the support of the support rod 1. Before the abutment rod 8 is inserted into the stabilizing block 6, the screw 703 needs to be rotated to pull the anti-movement rod 701 away from the stabilizing block 6. After the abutment rod 8 is inserted into the stabilizing block 6, it can be moved. The anti-movement rod 701 allows it to enter the interior of the abutment rod 8, thereby restricting the position of the abutment rod 8. Then, the screw 703 on the anti-movement plate 702 is rotated to enter the anti-movement rod 701, further restricting its position. This fixes the position of the abutment rod 8, facilitating stable use. During use, the abutment rod 8 can be easily inserted into the ground using the ground spike 14, and the handle allows for easy gripping. With this structure, when foundation pit support is required, stability can be increased by using several support rods 1 in conjunction with the fixing frame 3, and the abutment rod 8 can also ensure the stability of the support. During use, it can reduce assembly time while ensuring the support effect, reducing the need for special equipment and connections, making foundation pit support more convenient.
