[0019] like Figure 1-3 As shown, a foundation pit support device for building protection includes a horizontal support rod 1 and a vertical support rod 2, wherein the horizontal support rod 1 and the vertical support rod 2 are arranged at right angles and fixedly connected.

[0020] The end of the horizontal support rod 1 away from the vertical support rod 2 is connected to a first gripping component via a first mounting and fixing component.

[0021] The first mounting and fixing assembly includes a first sliding telescopic rod 5 and a first fastening bolt 8. A horizontally arranged first sliding groove 3 is provided on the end of the horizontal support rod 1 away from the vertical support rod 2. A first adjusting groove 7 communicating with the first sliding groove 3 is provided on the top surface of the horizontal support rod 1. One end of the first sliding telescopic rod 5 is inserted into the first sliding groove 3. The first fastening bolt 8 is threadedly connected to one end of the first sliding telescopic rod 5 inserted into the first sliding groove 3. The screw head of the first fastening bolt 8 is pressed against the top surface of the horizontal support rod 1. The end of the first sliding telescopic rod 5 away from the first fastening bolt 8 is connected to the first gripping assembly.

[0022] The first gripping assembly includes a first mounting plate 25, a first fixing cylinder 11, and a first gripping spike 12. The first mounting plate 25 is connected to the end of the first sliding telescopic rod 5. The first fixing cylinder 11 is embedded in the first mounting plate 25, and the first gripping spike 12 is slidably connected in the first fixing cylinder 11.

[0023] The first installation and fixing assembly first adjusts the relative distance between the first ground-gripping nail 12 and the horizontal support rod 1 through the sliding connection between the first sliding telescopic rod 5 and the first sliding groove 3. While the first sliding telescopic rod 5 is extending and retracting, it drives the first fastening bolt 8 to slide and adjust in the first adjustment groove 7. After the adjustment is completed, the first fastening bolt 8 is tightened, thereby fixing the first sliding telescopic rod 5 and the horizontal support rod 1 relative to each other. Then, the first ground-gripping nail 12 can be driven into the ground around the pit, thereby fixing the horizontal support rod 1 to the ground around the pit.

[0024] The end of the vertical support rod 2 away from the horizontal support rod 1 is connected to a second gripping component via a second mounting and fixing component.

[0025] The second mounting and fixing assembly includes a second sliding telescopic rod 6 and a second fastening bolt 10. A vertically arranged second sliding groove 4 is provided on the end of the vertical support rod 2 away from the horizontal support rod 1. A second adjusting groove 9 communicating with the second sliding groove 4 is provided on the outer wall of the vertical support rod 2. One end of the second sliding telescopic rod 6 is inserted into the second sliding groove 4. The second fastening bolt 10 is threadedly connected to one end of the second sliding telescopic rod 6 inserted into the second sliding groove 4. The thread head of the second fastening bolt 10 is pressed against the outer wall of the vertical support rod 2. The end of the second sliding telescopic rod 6 away from the second fastening bolt 10 is connected to the second gripping assembly.

[0026] The second gripping assembly includes a second mounting plate 26, a second fixing cylinder 13, and a second gripping spike 24. The second mounting plate 26 is connected to the end of the second sliding telescopic rod 6. The second fixing cylinder 13 is embedded in the second mounting plate 26, and the second gripping spike 24 is slidably connected in the second fixing cylinder 13.

[0027] The second installation and fixing assembly first adjusts the relative height between the second ground anchor 24 and the vertical support rod 2 through the sliding connection between the second sliding telescopic rod 6 and the second sliding groove 4. While the second sliding telescopic rod 6 is extending and retracting, it drives the second fastening bolt 10 to slide and adjust within the second adjustment groove 9. After the adjustment is completed, the second fastening bolt 10 is tightened, thereby fixing the second sliding telescopic rod 6 and the vertical support rod 2 relative to each other. Then, the second ground anchor 24 can be driven into the inner wall of the pit, thereby fixing the vertical support rod 2 to the inner wall of the pit.

[0028] A compression assembly is installed on the vertical support rod 2. The compression assembly includes fixed rods 14 fixedly connected to both sides of the vertical support rod 2 via connecting plates. A lifting frame 15 is slidably connected to the body of the fixed rod 14. A mounting frame 16 is connected to the end of the lifting frame 15 away from the fixed rod 14. A third fixed cylinder 17 is connected to both ends of the mounting frame 16. A sliding rod 18 is slidably connected inside the third fixed cylinder 17. A compression block 19 is connected between the ends of the two sliding rods 18 near the inner wall of the pit. The other ends of the two sliding rods 18 are connected to a drive frame 20. A threaded cylinder 21 is embedded in the middle of the drive frame 20. A screw 22 is threadedly connected inside the threaded cylinder 21. One end of the screw 22 is rotatably connected to the mounting frame 16, and the other end of the screw 22 is connected to a knob 23. The compression assembly pushes and compresses the inner wall of the pit, thereby preventing deformation and collapse of the inner wall of the pit.

[0029] The operation process of this utility model is as follows:

[0030] In use, the horizontal support rod 1 is first fixedly installed on the ground outside the pit using the first installation component, and the vertical support rod 2 is fixedly installed on the inner wall of the pit using the second installation component. Then, the relative height of the extrusion block 19 is adjusted by the sliding connection between the fixed rod 14 and the sliding lifting frame 15. After adjustment, the knob 23 is turned to rotate the screw 22, thereby moving the drive frame 20. The drive frame 20 drives the slide rod 18 to slide in the third fixed cylinder 17, thereby moving the extrusion block 19 towards the inner wall of the pit. The extrusion block 19 then pushes and compresses the inner wall of the pit, thereby preventing deformation and collapse of the inner wall of the pit.

[0031] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
