[0024] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0025] As Figures 1 to 4 shown, a support structure for foundation pit support with quick assembly provided by an embodiment of the present utility model includes a retaining plate 1, a plurality of first pile columns 2, and a fixing plate 3.

Sliding sleeves 43 are fixedly connected to both the left side and the right side of the support plate 41.

[0030] Adopting the above solution: By arranging the support assembly 4, when it is necessary to support the retaining plate 1, the second pile column 42 is inserted into the ground, and at this time, the support plate 41 can support the retaining plate 1, and the second pile column 42 can prevent the support plate 41 and the retaining plate 1 from moving.

[0032] Adopting the above solution: By arranging the travel rod 8 and the positioning ring 9, when the support plate 41 moves downward, the cooperation between the travel rod 8 and the sliding sleeve 43 can control the moving position of the support plate 41, and the positioning ring 9 can control the moving position of the sliding sleeve 43.

[0033] Refer to Figure 3 , the extrusion assembly 5 includes a rotating plate 51, a mounting plate 52 is fixedly connected to the top of the support plate 41, a square groove 53 is formed in the inner cavity of the rotating plate 51, a rotating rod 54 is movably connected to the inner cavity of the square groove 53, a square ring 55 is fixedly connected to the surface of the rotating rod 54, and the rear side of the rotating rod 54 penetrates through the rotating plate 51 and the fixing plate 3 and extends into the inner cavity of the accommodation groove 6.

[0034] Adopting the above solution: By setting the extrusion assembly 5, when it is necessary to conveniently apply force to insert the second pile 42 into the ground, rotating the rotating rod 54 will drive the rotating plate 51 to rotate. The rotation of the rotating plate 51 will drive the extrusion wheel 11 to extrude the inner wall in the extrusion hole 10 on the front side of the mounting plate 52. At this time, the downward movement of the mounting plate 52 will drive the support plate 41 to descend, and the descent of the support plate 41 will drive multiple second piles 42 to be inserted into the soil.

[0035] Reference Figure 3 , an extrusion hole 10 is opened on the front side of the mounting plate 52. The inner cavity of the extrusion hole 10 is movably connected with an extrusion wheel 11, and the front side of the extrusion wheel 11 is fixedly connected to the rotating plate 51.

[0036] Adopting the above solution: By setting the extrusion hole 10 and the extrusion wheel 11, when the rotating plate 51 rotates, it will drive the extrusion wheel 11 to extrude the inner wall in the extrusion hole 10, and the friction between the extrusion wheel 11 and the extrusion hole 10 is relatively small. In this way, the downward movement of the mounting plate 52 can be driven by rotating the rotating rod 54, and the downward movement of the mounting plate 52 can drive the support plate 41 to descend.

[0037] Reference Figure 4 , the rebounding assembly 7 includes an extrusion plate 71. The front side of the extrusion plate 71 is fixedly connected to the rotating rod 54. A circular plate 72 is movably connected to the inner cavity of the receiving groove 6. A guide rod 73 is fixedly connected to the front side of the circular plate 72. A spring 74 is sleeved on the surface of the guide rod 73. The front side of the guide rod 73 penetrates through the extrusion plate 71 and contacts the inner wall of the receiving groove 6.

[0038] Adopting the above solution: By setting the rebounding assembly 7, when the fixed block 12 fixed on the extrusion plate 71 driven by the rotating rod 54 disengages from the fixing hole 13, the spring 74 will undergo elastic deformation to drive the extrusion plate 71 and the rotating rod 54 back to their original positions. At this time, the extrusion plate 71 can drive the fixed block 12 to be inserted into the fixing hole 13.

[0039] Reference Figure 4 , a fixed block 12 is fixedly connected to the front side of the extrusion plate 71. A fixing hole 13 matching the fixed block 12 is opened on the front side of the receiving groove 6.

[0041] The working principle of the present utility model:

[0042] During use, first install multiple retaining plates 1. When installing, the first pile 2 will be inserted into the soil. Then, hold the rotating rod 54 tightly and push it backward. The movement of the rotating rod 54 will drive the square ring 55 to move within the square groove 53. The movement of the rotating rod 54 will drive the pressing plate 71 to compress the spring 74 within the receiving groove 6. At this time, the guiding rod 73 can control the stroke of the pressing plate 71. After the pressing plate 71 drives the fixing block 12 to disengage from the fixing hole 13, rotating the rotating rod 54 will drive the rotating plate 51 to rotate. The rotation of the rotating plate 51 will drive the pressing wheel 11 to press against the inner wall within the pressing hole 10 on the front side of the mounting plate 52. At this time, the downward movement of the mounting plate 52 will drive the support plate 41 to descend. The descent of the support plate 41 will drive multiple second piles 42 to be inserted into the soil. Subsequently, the rotating rod 54 can be released. The elastic deformation of the spring 74 will drive the pressing plate 71 back to its original position. The movement of the pressing plate 71 will drive the fixing block 12 to be inserted into the fixing hole 13 at a suitable position. At this time, the position of the support plate 41 can be fixed.

[0043] In summary, for the support structure for foundation pit support with rapid assembly, through the combined use of the support assembly 4, the extrusion assembly 5, the receiving groove 6, and the resilience assembly 7, the rotation of the rotating plate 51 will drive the pressing wheel 11 to press against the inner wall within the pressing hole 10 on the front side of the mounting plate 52. At this time, the downward movement of the mounting plate 52 will drive the support plate 41 to descend. The descent of the support plate 41 will drive multiple second piles 42 to be inserted into the soil, solving the problem that the support structure is composed of multiple piles and inclined plates, and when workers first insert multiple piles into the ground and then connect them to the inclined plates through bolts, it takes time to build the structure when multiple retaining plates need to be supported.
