[0002] Currently, foundation pit slope support is an engineering measure used during excavation to prevent slope collapse and protect surrounding structures. Its primary purpose is to ensure the stability of the foundation pit slope, thereby preventing earthwork collapse and potential accidents. Related technologies typically use methods such as earthwork side push, steel support, soil nailing walls, geogrids, and anchor support to prevent soil instability.
[0003] In existing foundation pit slope support technologies, commonly used support structures often suffer from low transportation and installation efficiency. Specifically, traditional support device components are mostly monolithic or fragmented. Monolithic structures are bulky and heavy, taking up a lot of space during transportation and making loading and unloading inconvenient. Fragmented components require on-site assembly one by one, and the connections between components are poorly compatible, making the adjustment process cumbersome. For example, the steel bar support method requires the sequential installation and bundling of several steel bars, which is slow, resulting in a long installation and construction time, seriously affecting construction efficiency.

[0029] The two ends of the protective frame 2 are respectively provided with a second rotating connection end, and the two adjacent protective frames 2 are rotatably connected by inserting an axis rod into the second rotating connection end; through this connection method, several layers of protective frames 2 can be quickly installed to meet the needs of foundation pit slope support at different heights;
[0030] During installation, a number of retaining members 6 are installed between two adjacent protective frames 2 at the same horizontal height; the retaining members 6 are used to quickly fix the protective frames 2 at the same height relative to each other.
[0031] The support frame 1 includes a square outer frame 11, a reinforcement frame 12 is fixedly connected to the square outer frame 11, a plurality of connecting rod groups 13 are fixedly connected between the reinforcement frame 12 and the square outer frame 11, the connecting rod group 13 is fixedly connected to the positioning ring 100, and a plurality of connecting rod groups 15 are fixedly connected to the outside of the square outer frame 11, and the outer end of the connecting rod group 15 is fixedly connected to the positioning ring 100, and the fixing rod 4 is inserted into the positioning ring 100;
[0032] The protective frame 2 includes a rectangular outer frame 21 , a plurality of inner frames 22 are fixedly connected to the rectangular outer frame 21 , a plurality of connecting rod groups 23 are fixedly connected between the inner frames 22 and the rectangular outer frame 21 , and the connecting rod group 23 is fixedly connected to the positioning ring 100 .
[0033] The surface of the mounting seat 3 is provided with a plurality of positioning holes 30, the spacing of the positioning holes 30 matches the spacing of the positioning rings 100 provided in the support frame 1, and a support frame 31 is fixedly connected to the mounting seat 3, and the top of the support frame 31 is rotated by a rotating shaft to install the rotating connection end 2 of the protective frame 2.
[0034] The fixing rod 4 is provided with a limit end 40 on the outside; the upper end of the fixing rod 4 is provided with a hanging hole for connecting a hook for quick pulling out and disassembly.
[0035] When the device is in use, according to the construction requirements, a suitable number of support device components are selected for transportation to the construction site, and several support frames 1 are flipped over and unfolded and placed in the support construction area (the root of the foundation pit slope). When it is necessary to install at the corner of the foundation pit, the rotating connector 5 between two adjacent support frames 1 can be removed to release the restraint, and then installed in the corner area; a hole is drilled at the position of the positioning ring 100 of the support frame 1. The diameter of the hole can be slightly smaller than the diameter of the fixing rod 4. The soil generated by the drilling can bury the device.

According to the basic slope conditions required for support, several layers of protective frames 2 can be installed on the upper part of the protective frame 2, but the upper limit of the number of installation layers of the protective frame 2 needs to be set according to the slope angle to ensure safety. After the foundation pit slope support device is installed according to the above steps, the foundation pit slope can be effectively supported to ensure construction safety. This device is particularly suitable for foundation pit slope support scenarios that require rapid construction and installation. The disassembly process is the opposite of the installation process, and the disassembly process is also simple and fast.
