[0002] When constructing a building, a foundation pit will be dug as needed. Once the excavation is completed and the depth is relatively deep, a support device is needed to support the pit wall to prevent the pit from collapsing due to moisture in the soil.

[0003] Most of the existing foundation pit support and reinforcement devices are fixed structures, which are not convenient to install and disassemble, and are therefore inconvenient to carry and transport. In addition, the length of the support beams of the foundation pit support and reinforcement devices generally cannot just meet the width of the foundation pit, resulting in the foundation pit support and reinforcement devices being too wide to be lowered into the foundation pit, or the foundation pit support and reinforcement devices being too narrow to leave support gaps. In response to the above problems, the inventors have proposed a detachable deep foundation pit support device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0021] like Figure 1-4 As shown, the utility model provides a detachable deep foundation pit support device, including a base plate 1, a convex plate 3 is fixedly connected to the middle of the top surface of the base plate 1, and vertical plates 5 are slidably arranged above the base plate 1 and on both sides of the convex plate 3, and a cross beam 19 is fixedly connected to the side of the vertical plate 5 facing the convex plate 3, and a slot 4 is penetrated through the side wall of the convex plate 3, and the cross beam 19 corresponds to the slot 4 and is slidably inserted, and the side wall of the vertical plate 5 is fixedly connected to the vertical plate 10, and the side wall of the vertical plate 10 is detachably provided with a concave plate 14, and the concave plate 14 is hinged to a support rod 16 on the side facing away from the vertical plate 10.

[0022] The top surface of the base plate 1 and both sides of the protruding plate 3 are fixedly connected to the slide rail 2. The bottom surface of the vertical plate 5 is fixedly connected to the slider 6, which slides in cooperation with the slide rail 2. By adopting the above technical solution, the slider 6 can move on the slide rail 2 via the slide groove 7, thereby adjusting the position of the vertical plate 5 and the support distance to improve the applicability. The slider 6 can also be removed from the slide rail 2 to disassemble the device for portability.

[0023] The side of the slider 6 facing away from the vertical plate 5 is provided with a slide groove 7, which is slidably connected to the slide rail 2. A protrusion 8 is fixedly connected to the side wall of the slider 6, and a first ground spike 9 is inserted into the top surface of the protrusion 8. By adopting the above technical solution, after the slider 6 moves to the desired position on the slide rail 2 through the slide groove 7, the first ground spike 9 is embedded in the ground. The first ground spike 9 can limit the slider 6 to prevent further movement of the slider 6 after adjustment.

[0024] The concave opening of the concave plate 14 matches the thickness of the vertical plate 10. A second opening 15 is provided through the side wall of the concave plate 14, and a first opening 11 is provided through the side wall of the vertical plate 10. The diameter of the first opening 11 is the same as that of the second opening 15. Multiple first openings 11 are distributed at vertical intervals along the vertical plate 10, and also include a double-headed screw 12. The double-headed screw 12 passes through the second opening 15 and the first opening 11, and the two ends of the double-headed screw 12 are connected to nuts 13.

[0025] By adopting the above technical solution, the nut 13 is unscrewed to separate the nut 13 from the double-headed screw 12, and the double-headed screw 12 can be pulled to withdraw the double-headed screw 12 from the first opening 11 and the second opening 15, so that the concave plate 14 can be removed from the vertical plate 10 for carrying. When installation is required, the concave opening of the concave plate 14 is matched with the vertical plate 10, and the second opening 15 is made to correspond to the corresponding first opening 11. The double-headed screw 12 is inserted into the first opening 11 and the second opening 15, and the nut 13 is tightened to adjust the position of the support rod 16. The support rod 16 can be limited and fixed by the second ground nail 18. The support rod 16 can improve the stability of the device and avoid bending and deformation when it is under greater pressure.

[0026] The end of the support rod 16 away from the concave plate 14 is hinged to a limit plate 17, and a second ground spike 18 is inserted into the top surface of the limit plate 17. By adopting the above technical solution, after adjusting the position of the support rod 16, the second ground spike 18 is embedded in the ground to limit and fix the support rod 16.

[0027] Working principle: When the present invention is in use, the slide block 6 can be moved on the slide rail 2 through the slide groove 7, so that the position of the vertical plate 5 can be adjusted, and then the support distance can be adjusted to improve applicability. The slide block 6 can be pulled out from the slide rail 2 to disassemble the device for portability. When the vertical plate 5 is moved to the desired position, the first ground nail 9 is embedded in the ground. The first ground nail 9 can limit the position of the slide block 6, and then the position of the vertical plate 5 can be limited.

[0028] When the concave plate 14 needs to be installed, the concave opening of the concave plate 14 is matched with the vertical plate 10, and the second opening 15 is made to correspond to the corresponding first opening 11. The double-headed screw 12 is inserted into the first opening 11 and the second opening 15, and the nut 13 is tightened to adjust the position of the support rod 16. The support rod 16 can be limited and fixed by the second ground nail 18. The support rod 16 can improve the stability of the device and avoid bending deformation when subjected to large pressure;

[0029] When the concave plate 14 needs to be disassembled, the nut 13 is unscrewed to separate the nut 13 from the double-headed screw 12, and the double-headed screw 12 can be pulled out from the first opening 11 and the second opening 15, so that the concave plate 14 can be removed from the vertical plate 10 for carrying.
