The key points of its technical solution include being arranged on the side wall of the foundation pit, including a plurality of assembled support plates covering the side wall of the foundation pit and overlapping each other, and a sleeve inserted into the aperture of the side wall of the foundation pit from the outside of the assembled support plate, and a steel bar body inserted in the sleeve and detachably connected to the sleeve, wherein the steel bar body includes a plurality of steel bar support rods detachably connected end to end in sequence. Through the above technical solution, the soil nail support structure can be conveniently recycled.

[0003] The above device can facilitate the recycling of the soil nail support structure, but in actual use, since multiple sets of overlapped assembled support plates are installed on the side walls of the foundation pit, it is troublesome to install and disassemble the multiple sets of support plates, resulting in a longer construction time. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present application provides an assembled soil nail wall support structure, which overcomes the shortcomings of the prior art and aims to solve the problem that since multiple groups of assembled support plates overlapping each other are installed on the side walls of the foundation pit, it is troublesome to install and disassemble the multiple groups of support plates, resulting in a long construction time.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an assembled soil nail wall support structure, comprising a foundation pit body, the slope surface of the foundation pit body is paved with a flexible layer, a plurality of groups of support installation cavities are arranged inside the flexible layer, support installation cavities are fixedly installed inside the support installation cavities, support panels are fixedly installed at the plurality of support installation cavities inside the flexible layer, a through hole is opened in the middle of the support panel, and corresponding sockets are opened on both side walls of the flexible layer located on both sides of the through hole, and a detachable steel bar structure is inserted at the through hole inside the flexible layer.

[0006] By adopting the above technical scheme, by fixing multiple groups of support panels inside the flexible layer, by laying the flexible layer on the slope of the foundation pit body, and then driving the detachable steel structure into the inside of the foundation pit body through the perforation, the support panels can be fixed, so that the support panels can support the foundation pit body. The same is true when the support panels are disassembled. After removing the detachable steel structure, the flexible layer is separated from the foundation pit body, and the support panels are separated from the foundation pit body at the same time. By installing several groups of support panels inside the flexible layer, it is convenient to install and disassemble several groups of support panels as a whole, which is conducive to convenient and fast construction. At the same time, the material of the flexible layer is civil cloth, which is convenient to roll up after disassembly and transport to the next location for recycling, which greatly saves the use of materials.

[0007] As a preferred technical solution of the present application, a sleeve is sleeved on the outer surface of the detachable steel structure, and the bottom of the detachable steel structure is threadedly connected to the inside of the sleeve, and the sleeve is inserted into the inside of the foundation pit body.

[0008] By adopting the above technical solution, holes are drilled on the side of the foundation pit body in advance, a sleeve is put on the detachable steel structure, inserted into the reserved holes, and grouting is performed on the outside of the sleeve, so that the detachable steel structure can be recycled conveniently.

[0009] As a preferred technical solution of the present application, the detachable steel bar structure includes four groups of steel bar support rods, which are inserted into the interior of the sleeve, one end of the steel bar support rod is fixedly installed with a thread block, and the end of the steel bar support rod away from the thread block is provided with a thread groove, and two adjacent groups of the steel bar support rods are detachably connected through the thread block and the thread groove.

[0010] By adopting the above technical solution, the two adjacent groups of steel bar support rods are detachably connected through the threaded blocks and the threaded grooves, which makes it easy to decompose the detachable steel bar structure into multiple groups of shorter steel bar support rods, so that the detachable steel bar structure can be easily transported to the next location when it is recycled.

[0011] As a preferred technical solution of the present application, two groups of pointed plugs are fixedly installed in the three groups of support installation cavities arranged in the same longitudinal direction inside the flexible layer, and the three groups of support panels arranged in the same longitudinal direction are located between the two groups of pointed plugs.

[0012] By adopting the above technical scheme, the slope of the foundation pit body is supported by the pointed plug blocks to assist the support panel. At the same time, when the flexible layer needs to be rolled up, multiple groups of pointed plug blocks are installed according to the rolling direction of the flexible layer, which will not affect the rolling up of the flexible layer while improving the support effect on the foundation pit body.

[0013] As a preferred technical solution of the present application, an anti-slip layer is fixedly installed on a side of the flexible layer close to the foundation pit body.

[0014] By adopting the above technical solution, the fixing effect of the support panel when it contacts the slope of the foundation pit body is improved through the anti-slip layer.

[0015] As a preferred technical solution of the present application, a pointed plug is fixedly installed at one end of the sleeve.

The same is true when the support panels are disassembled. After removing the detachable steel structure, the flexible layer is separated from the foundation pit body, and the support panels are separated from the foundation pit body at the same time. By installing several groups of support panels inside the flexible layer, it is convenient to install and disassemble several groups of support panels as a whole, which is conducive to convenient and fast construction. At the same time, the material of the flexible layer is civil cloth, which is convenient to roll up after disassembly and transport to the next location for recycling, which greatly saves the use of materials.
