[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1-Figure 3 As shown, the utility model provides a side wall support structure for a foundation pit of a construction project, comprising: a guard plate 1, which is hinged to a bottom plate 2, and the guard plate 1 supports the side wall of the foundation pit; a support member 4, which is installed between the guard plate 1 and the bottom plate 2, and the support member 4 supports the guard plate 1; a fixing member 5, which is arranged below the bottom plate 2, and the fixing member 5 fixes the bottom plate 2.

[0023] The bottom plate 2 and the guard plate 1 are hinged by a hinge shaft 3. When not in use, the guard plate 1 can be folded with the bottom plate 2. When the bottom plate 2 and the guard plate 1 are in a folded state, the support member 4 between the bottom plate 2 and the guard plate 1 is also in a folded state, which is convenient for the transportation of the support structure.

[0024] The support member 4 includes a first support groove 401, a second support groove 402 and a support plate 403. The first support groove 401 is fixed on the base plate 2, and the second support groove 402 is fixed on the guard plate 1. One end of the first support groove 401 is hinged to one end of the second support groove 402 through a hinge axis, and one end of the support plate 403 is hinged to the second support groove 402 through a hinge axis, and its hinge axis is fixed in the second support groove 402. The other end of the support plate 403 is connected with a sliding column 404, and the sliding column 404 passes through the sliding groove 405. Both ends of the support plate 403 are located outside the first support groove 401, and the sliding column 404 can slide in the first support groove 401. A sliding groove 405 is opened in the first support groove 401, and the sliding groove 405 is adapted to the sliding column 404. The sliding column 404 can slide along the sliding groove 405, driving one end of the support plate 403 to slide in the first support groove 401.

[0025] A limiting groove 406 is provided on one side of the sliding groove 405 close to the second supporting groove 402 . The limiting groove 406 is matched with the sliding column 404 and is used to fix the position of the sliding column 404 .

[0026] When it is necessary to support the side wall of the foundation pit, the guard plate 1 is rotated and unfolded. During the rotation of the guard plate 1, one end of the support plate 403 installed in the second support groove 402 pulls the support plate 403 to unfold. At this time, the slide column 404 slides along the slide groove 405 toward the direction close to the guard plate 1. When the guard plate 1 and the bottom plate 2 are in a vertical state, the slide column 404 slides into the limit groove 406. The limit groove 406 fixes the slide column 404, thereby fixing the support plate 403. The support plate 403, the first support groove 401 and the second support groove 402 form a triangular stable support structure, which supports the guard plate 1.

[0027] When the support work is completed, lift the sliding column 404 upward so that the sliding column 404 disengages from the limiting groove 406 and folds the guard plate 1. At this time, the support plate 403 installed in the second support groove 402 pushes the sliding column 404 to slide away from the guard plate 1, and the second support groove 402 gradually folds with the first support groove 401, and the guard plate 1 gradually folds with the bottom plate 2, completing the disassembly of the guard plate 1, so that it is convenient for use when supporting the side wall of the foundation pit next time.

[0028] A fixing member 5 is fixed at the bottom of the bottom plate 2 . The fixing member 5 includes a bottom cone 501 and barbs 502 . The bottom cone 501 is fixed below the bottom plate 2 , and the barbs 502 are evenly fixed on the surface of the bottom cone 501 .

[0029] During installation, the base plate 2 is transported to the foundation pit, and the bottom cone 501 and the barbs 502 are hammered into the bottom of the foundation pit using a machine or tool to complete the fixation of the base plate 2. The barbs 502 can strengthen the fixation of the base plate 2.

[0030] In this embodiment, the bottom plate 2 and the guard plate 1 are rotatably connected by a hinge shaft, and a support member 4 is installed between the bottom plate 2 and the guard plate 1, the first support groove 401 is fixed to the bottom plate 2, the second support groove 402 is fixed to the guard plate 1, and the first support groove 401 and the second support groove 402 are hinged, the first support groove 401 and the second support groove 402 can rotate with the bottom plate 2 and the guard plate 1, when the guard plate 1 is needed to support the side wall of the foundation pit, the guard plate 1 is rotated so that the guard plate 1 and the bottom plate 2 are in a vertical state, and at the same time, the first support groove 401 and the second support groove 402 are also in a vertical state when they are unfolded. At this time, the sliding column 404 slides to the limit groove 406 and is fixed, so that the support The support plate 403 is fixed between the first support groove 401 and the second support groove 402. The support plate 403, the first support groove 401 and the second support groove 402 form a stable triangular structure, which is convenient for providing stable support for the guard plate 1, so that the guard plate 1 has a better supporting effect on the side wall of the foundation pit. This process is easy to install, saves time and effort, and is easy to disassemble. You only need to lift the sliding column 404 upward to disengage it from the limiting groove 406 and release the limit. The sliding column 404 drives the support plate 403 to slide, so that the second support groove 402 and the first support groove 401 are folded, and the guard plate 1 and the bottom plate 2 are folded, completing the disassembly of the guard plate 1. After folding, it is easy to transport and use next time.
