Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a temporary reinforcement device for building foundation pit, including a base plate 1, a rotatable support and reinforcement plate 2 at the top of the base plate 1, a support and reinforcement mechanism on the surface of the support and reinforcement plate 2 and the base plate 1, and an assembly docking mechanism on both sides of the support and reinforcement plate 2. The support and reinforcement mechanism includes: an insertion support component and an auxiliary pull-out component.

[0022] In this embodiment, preferably, the insertion support assembly includes an insertion hole 100 symmetrically opened through the surface of the support and reinforcement plate 2 and an insertion rod 101 disposed inside the insertion hole 100. An operating block 102 is fixed to the end of the insertion rod 101. A support groove 103 is symmetrically opened through the top of the bottom plate 1. A support rod 104 is disposed inside the support groove 103 to facilitate the positioning of the bottom plate 1 and the support and reinforcement plate 2.

[0023] In this embodiment, preferably, the auxiliary pull-out component includes a built-in groove 200 formed on the surface of the operating block 102 and an operating handle 201 disposed inside the built-in groove 200. A connecting shaft 202 is connected between the operating handle 201 and the built-in groove 200, which can pull the insertion rod 101 to retract into the insertion groove 100.

[0024] In this embodiment, preferably, a guide groove 300 is provided on one side of the support rod 104, and a guide block 301 is fixed on one side of the inner wall of the support groove 103, and the guide block 301 is slidably connected to the guide groove 300.

[0025] In this embodiment, preferably, the top of the base plate 1 is provided with a step groove 400, and the top of the base plate 1 is provided with a connecting groove 401 at both ends, which are respectively connected to the step groove 400 and the support groove 103. A pry bar 402 is provided inside the connecting groove 401, and a pry groove 403 is provided at equal intervals on the other side of the support rod 104. The end of the pry bar 402 is engaged with the pry groove 403 to facilitate prying the support rod 104.

[0026] In this embodiment, preferably, sliding grooves 500 are symmetrically provided on both sides of the inner wall of the connecting groove 401, and sliders 501 are symmetrically provided on both sides of the prying rod 402. The sliders 501 are slidably connected to the sliding grooves 500, allowing the prying rod 402 to slide inside the connecting groove 401. A rotating groove 502 is provided at the end of the slider 501, and rotating blocks 503 are symmetrically fixed on both sides of the prying rod 402. The rotating blocks 503 are rotatably connected to the rotating grooves 502, which can drive the prying rod 402 to rotate and lift the support rod 104.

The docking grooves 600 are fixed with docking blocks 601, which can allow other reinforcement structures to connect with the support and reinforcement plate 2 and play a docking guiding role.

[0028] The working principle and usage process of this utility model are as follows: When temporary reinforcement of the inner wall of a foundation pit is required, first place the base plate 1 inside the foundation pit, then rotate the support reinforcement plate 2 to fit against the side wall of the foundation pit, then press the operating block 102 to move the insertion rod 101 out of the insertion hole 100 and insert it into the soil of the side wall of the foundation pit, thus supporting and limiting the support reinforcement plate 2. Next, press the support rod 104 downward to move it out from the inside of the support groove 103 and insert it into the bottom of the foundation pit, thus positioning the base plate 1 for temporary reinforcement. When temporary reinforcement is no longer needed, the operating handle 201 on the surface of the operating block 102 can be turned out through the connecting shaft 202 from the inside of the internal groove 200, allowing the insertion rod to be pulled. The insertion rod 101 is moved out from the side wall of the pit and retracted into the insertion hole 100 to release the positioning of the support reinforcement plate 2. Then, the pry bar 402 is pushed to move inside the connecting groove 401 and drive the slider 501 to slide inside the sliding groove 500 and insert into the pry groove 403. Then, the pry bar 402 inside the foot groove 400 is pressed by stepping on it, so that it rotates inside the rotating groove 502 through the rotating block 503. This prying rod 104 is moved out from the bottom of the pit and retracted into the support groove 103, thus releasing the positioning of the bottom plate 1 and facilitating the release of the temporary reinforcement work. When it is necessary to connect other reinforcement plates with the support reinforcement plate 2, the docking groove 600 and the docking block 601 can be used to assemble and connect them.
