Technical Field

[0001] The present application relates to the technical field of foundation pit construction, and in particular to a foundation pit support system. Background Art

[0002] Foundation pit construction is an important part of civil engineering construction. When the foundation pit is excavated, the stability of the soil around the foundation pit is directly related to the safety of the foundation pit construction and the surrounding environment. Therefore, a support system must be set up around the foundation pit to withstand the pressure of the soil around the foundation pit and limit the displacement of the soil.

[0003] Generally speaking, due to the differences in size or environment of each construction site, different forms of foundation pit support structures are set up. At present, the commonly used foundation pit support structure is generally a foundation pit support system combining retaining walls and internal supports. That is, before the foundation pit is excavated, concrete is poured around the foundation pit to form a continuous closed reinforcement wall, and a support structure is constructed in the foundation pit to support the reinforcement wall, thereby achieving the support function of the foundation pit.

[0004] However, as a temporary construction structure, the supporting structure adopts cast-in-place reinforced concrete structure, which makes the supporting structure unable to be reused, further reducing the economic efficiency of the foundation pit project. Utility Model Content

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] An embodiment of the present application discloses a foundation pit support system.

[0021] Reference Figure 1 and Figure 2The foundation pit support system includes a plurality of support plates 1 abutting against the inner wall of the foundation pit, and a connecting piece 2 is detachably connected between two adjacent support plates 1, and a plurality of support plates 1 are spliced ​​and arranged mutually through the connecting piece 2. A plurality of first conical fixing nails 11 are welded to the lower end of the support plate 1, and a plurality of second conical fixing nails 12 are welded to the side of the support plate 1 facing the inner wall of the foundation pit. A support rod 3 is arranged on the side of the support plate 1 facing away from the foundation pit wall, and a through groove 13 is longitudinally provided on the side of the support plate 1 facing away from the foundation pit wall, and an adjusting mechanism 4 for adjusting the angle of the support rod 3 is arranged in the through groove 13, and the adjusting mechanism 4 is connected to the upper end of the support rod 3, and the lower end of the support rod 3 is inserted into the ground.

[0022] Reference Figure 1 The connecting piece 2 includes a connecting block 21 that is detachably connected to the sides of two adjacent supporting plates 1. Limiting edges 22 with arc-shaped cross-sections are extended and welded on both sides of the sides of the supporting plates 1. The connecting block 21 is provided with limiting grooves 23 for the limiting edges 22 to be engaged along the longitudinal direction. The lower end of the connecting block 21 is open, so that the connecting block 21 can be connected and sleeved on the sides of the two adjacent supporting plates 1, and then the two adjacent supporting plates 1 can be spliced.

[0023] Reference Figure 1 The adjusting mechanism 4 includes a threaded rod 41 rotatably connected to the through slot 13 through a bearing, and a rectangular moving block 42 is threadedly sleeved on the threaded rod 41, and both side walls of the moving block 42 are slidably connected to the inner walls of both sides of the through slot 13. The upper end of the support rod 3 is hinged to the outer wall of the moving block 42, and a driving assembly 43 for driving the threaded rod 41 to rotate is provided on the inner side of the support plate 1. The driving assembly 43 includes a worm wheel 431 coaxially fixed to the threaded rod 41, and the support plate 1 is rotatably connected to a worm 432 meshing with the worm wheel 431 through a bearing, and a hand wheel 433 is fixed to the end of the worm 432.

[0024] After several support plates 1 are spliced ​​together and rest against the inner wall of the foundation pit, in order to support the support plates 1, the lower end of the support rod 3 can be inserted into the soil first, and then the hand wheel 433 is turned to drive the worm 432 to rotate, so that the worm wheel 431 drives the threaded rod 41 to rotate, and then drives the moving block 42 to move downward, so that the moving block 42 applies a downward force to the support rod 3, so that the lower end of the support rod 3 can be inserted into a deeper position.

[0025] Reference Figure 1 and Figure 3In order to further reinforce the support rod 3, the support rod 3 is provided with a mounting block 5 along its length direction. The mounting block 5 can slide to any position of the support rod 3 and be positioned by bolts. The side walls of the mounting block 5 are respectively connected with rotating blocks 51, and the rotating blocks 51 are slidably penetrated with a reinforcing rod 52 for inserting into the ground. The lower end of the reinforcing rod 52 is set in a cone shape, and the reinforcing rod 52 of a suitable length can be selected according to the actual situation. Therefore, after the lower end of the support rod 3 is inserted into the ground, the mounting block 5 can be moved to a suitable position and fixed by bolts, and then the lower end of the reinforcing rod 52 is inserted into the ground, so that the support rod 3 can support the support plate 1 more stably.

[0026] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
