[0002] The foundation pit slope is a very important aspect of the foundation pit project. Its design and construction are directly related to the safety and stability of the project. In order to ensure the stability of the foundation pit during excavation and prevent slope collapse or landslide, a support device needs to be set on the foundation pit slope. Usually, the foundation pit slope support mainly uses a gravity retaining wall, and the reinforced concrete structure resists a large earth pressure. However, there is a certain difficulty in recycling the concrete retaining wall. Secondly, the inclination angles of different foundation pit slopes are different, and the flexibility of the traditional foundation pit slope support is relatively low, lacking the adjustment ability. In view of the above problems, the inventor proposes a reusable foundation pit slope support mechanism to solve the above problems. Content of the Utility Model

[0023] By adopting the above technical solution, the protective wall panel 31 is slidably installed in the flipping frame 2, and the protective wall panel 31 is limited by the bolt 33 to prevent the protective wall panel 31 from moving.

[0024] The support angle adjustment assembly 4 includes a threaded rod 41 and two symmetrically distributed sliding plates 42. The threaded rod 41 is rotatably installed in the middle of the base 1. The two sliding plates 42 are respectively slidably installed in the base 1. A connecting rod 44 is sleeved on the outer wall of the threaded rod 41, and both ends of the connecting rod 44 are respectively slidably connected to the corresponding sliding plate 42. Adjusting rods 43 are rotatably provided at the tops of the two sliding plates 42, and the tops of the adjusting rods 43 are rotatably connected to the flipping frame 2.

[0025] By adopting the above technical solution, the flipping frame 2 drives the protective wall panel 31 to rotate and adjust synchronously, and the inclination angle of the protective wall panel 31 is adjusted according to the protection needs.

[0026] An inclined groove 38 is formed in the middle of the protective wall panel 31, and a soil nail 39 is inserted through the inclined groove 38.

[0027] By adopting the above technical solution, the soil nail 39 is obliquely inserted into the foundation pit soil through the inclined groove 38, effectively enhancing the stability of the slope.

[0028] A sliding groove 37 for cooperating with the protective wall panel 31 is formed in the flipping frame 2, and the protective wall panel 31 is slidably installed in the flipping frame 2 through the sliding groove 37.

[0029] By adopting the above technical solution, the protective wall panel 31 is slidably installed in the flipping frame 2 through the sliding groove 37.

[0030] Two symmetrically distributed guide grooves 46 are formed in the base 1, and the two sliding plates 42 slide in the corresponding guide grooves 46 respectively.

[0031] By adopting the above technical solution, the sliding plate 42 slides under the guidance of the guide groove 46.

[0032] Four symmetrically distributed fixing seats 21 are fixedly provided on one side of the top of the base 1, and a fixing shaft 22 is fixedly provided between two adjacent fixing seats 21. The flipping frame 2 is rotatably sleeved on the outer wall of the fixing shaft 22.

[0033] By adopting the above technical solution, the flipping frame 2 rotates and adjusts with the fixing shaft 22 as the axis.

[0034] Four symmetrically distributed ground holes 51 are formed on the side of the base 1 away from the flipping frame 2, and ground nails 5 are inserted into the ground holes 51.

[0036] A handle 45 is fixedly provided at the end of the threaded rod 41.

[0037] By adopting the above technical solution, the rotation of the handle 45 drives the synchronous rotation of the threaded rod 41.

[0038] Working principle: First, place the base 1 at the corresponding position at the bottom of the foundation pit. Fix the base 1 by inserting the ground nail 5 through the ground hole 51 into the soil at the bottom of the foundation pit. Then, manually pull the corresponding two bolts 33 to separate the bolts 33 from the flipping frame 2. Then, install the protective wall panel 31 along the sliding groove 37 into the flipping frame 2 so that the limiting holes 36 are aligned with the bolts 33. Then, release the bolts 33. Under the action of the spring 35 and the round plate 34, the bolts 33 are pushed to be inserted into the limiting holes 36 to limit the protective wall panel 31. According to the above same steps, install the base 1 at equal intervals according to the needs of the foundation pit. The distance between two adjacent bases 1 is the distance of one protective wall panel 31. Adjust the angle of the flipping frame 2 according to the inclination angle of the foundation pit. Manually rotate the handle 45 clockwise. The rotation of the handle 45 drives the rotation of the threaded rod 41. The threaded rod 41 drives the two sliding plates 42 to slide towards the flipping frame 2 under the guidance of the guiding groove 46 through the connecting rod 44. During the sliding process of the sliding plates 42, the flipping frame 2 is pushed to flip around the fixed shaft 22 through the adjusting rod 43. If reset is needed, just rotate the handle 45 counterclockwise in the reverse direction. After the adjustment of the flipping frame 2 is completed, install the protective wall panel 31 in the sliding groove 37 between two adjacent flipping frames 2 according to the above same steps. When the support is no longer needed and needs to be disassembled for secondary use, just disassemble it in the reverse order of the above installation steps.
