[0020] The utility model provides a slope retaining structure for a slope opening, such as Figure 1-4 As shown, it includes a cave arch body 1, and the outer walls on both sides of the cave arch body 1 constitute the boundaries of the slope land 2; a retaining assembly arranged on the outside of the slope land 2; the retaining assembly includes: a number of steel pipe columns 301 arranged in parallel; the outer walls on both sides of the steel pipe columns 301 are installed with a number of vertically arranged connecting sleeves 302 by welding, and the upper end surfaces of the connecting sleeves 302 are all open; a number of parallel pressure beam tubes 303 are arranged between every two adjacent steel pipe columns 301; connecting blocks 304 are installed on both sides of the bottom of the pressure beam tube 303 by welding, and the outer diameter size of the connecting block 304 is adapted to the inner diameter size of the connecting sleeve 302.

[0021] It should be noted that the traditional support structure usually adopts an integral bracket or steel frame for support; the integral bracket or steel frame requires a large space for transportation and storage, and is difficult to install and disassemble, requiring professional technicians and equipment. In addition, if a local bracket or steel frame needs to be repaired or replaced, the entire support structure needs to be dismantled, which will waste a lot of time and cost. The present solution facilitates transportation and storage by setting up arbitrarily detachable steel pipe columns 301 and pressure beam tubes 303, which can save space and reduce costs; during the on-site construction process, this design is also convenient for installation and adjustment, which can improve construction efficiency and reduce costs; when the local steel pipe columns 301 or pressure beam tubes 303 need to be repaired or replaced, they can be easily disassembled and repaired or replaced, which can reduce the time and cost required for repair and replacement, and improve the reliability and service life of the device in supporting the slope land 2.

[0022] Specifically, in this embodiment, this scheme mainly includes a cave arch body 1, and the outer walls on both sides of the cave arch body 1 constitute the boundaries of the slope land 2; a retaining assembly arranged on the outside of the slope land 2; the retaining assembly includes: a number of steel pipe columns 301 arranged in parallel; the outer walls on both sides of the steel pipe columns 301 are installed with a number of vertically arranged connecting sleeves 302 by welding, and the upper end surfaces of the connecting sleeves 302 are all open; a number of parallel pressure beam tubes 303 are arranged between every two adjacent steel pipe columns 301; connecting blocks 304 are installed on both sides of the bottom of the pressure beam tube 303 by welding, and the outer diameter of the connecting block 304 is adapted to the inner diameter of the connecting sleeve 302; the connecting block 304 is plugged into the connecting sleeve 302, so that the steel pipe column 301 and the pressure beam tube 303 are connected. When subjected to external force, the steel pipe column 301 and the pressure beam tube 303 will jointly bear the pressure and tension, and transmit the force to the outer walls of both sides of the cave arch body 1 through the connecting sleeve 302 and the connecting block 304, thereby enhancing the stability of the slope land 2; at the same time, since the outer diameter of the connecting block 304 is compatible with the inner diameter of the connecting sleeve 302, the stable installation of the steel pipe column 301 and the pressure beam tube 303 can be guaranteed, and the disaster resistance of the structure is further improved; in addition, since the steel pipe column 301 and the pressure beam tube 303 are arranged in a parallel state, the shape and quality of the slope land 2 can be better controlled, and the bearing capacity and disaster resistance of the land can be improved; the steel pipe column 301 and the pressure beam tube 303 that can be disassembled and assembled at will are convenient for transportation and storage, which can save space and reduce costs; during on-site construction, this design is also convenient for installation and adjustment, which can improve construction efficiency and reduce costs.

[0023] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the retaining assembly also includes: a plurality of casting holes 305 arranged at the bottom side of the slope land 2; a positioning steel hoop 306 is arranged in each of the casting holes 305, and the positioning steel hoop 306 is connected to the bottom side of the steel pipe column 301.

[0024] In this embodiment, first, the positioning steel hoop 306 is connected to the bottom side of the steel pipe column 301 to ensure that the steel pipe column 301 maintains the correct position during the pouring process; the positioning steel hoop 306 can prevent concrete and other materials from being lost or displaced during the pouring process, thereby ensuring the stability and reliability of the retaining assembly.

[0025] In a further preferred embodiment of the present invention, Figure 1-2 As shown, cement mortar is poured into the pouring hole 305 .

[0026] In this embodiment, the positioning steel hoop 306 and the steel pipe column 301 are fixed together by cement mortar material to form a more stable and reliable supporting structure.

[0027] In a further preferred embodiment of the present invention, Figure 1-3 As shown, it also includes a fixed ground nail 4; an assembly hole 5 is opened through the middle position of the pressure beam tube 303, and the fixed ground nail 4 penetrates the assembly hole 5 from the outside to the inside and is connected to the slope land 2.

[0028] In this embodiment, the retaining assembly can be more firmly fixed on the slope land 2, thereby improving the supporting capacity and stability. The design of the assembly hole 5 allows the fixed ground nails 4 to be easily installed and disassembled, which can be adjusted and optimized according to actual needs. For example, fixed ground nails 4 of different lengths and diameters can be selected according to the characteristics and requirements of the slope land 2 to adapt to different terrains and land conditions.

[0029] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the top of the fixed ground nail 4 is set in a cone shape, and a ground spike 6 is welded to the outer position of the top of the fixed ground nail 4, and the ground spike 6 is set in a ring shape.

[0030] In this embodiment, the top of the fixed ground nail 4 is set in a conical shape, which makes it easier for the fixed ground nail 4 to be inserted into the slope land 2 and can be more firmly fixed in the land. At the same time, the outer position of the top of the fixed ground nail 4 is welded with a ground spike 6, which can further enhance the connection strength and stability between the fixed ground nail 4 and the slope land 2 and prevent the land from slipping or collapsing.

[0031] In a further preferred embodiment of the present invention, Figure 3 As shown, the steel pipe column 301 and the compression beam tube 303 are both provided with reinforcing ribs 7, and the reinforcing ribs 7 are arranged in either a tic-tac-toe shape or a cross shape.

[0033] Working principle: First, the positioning steel hoop 306 is connected to the bottom side of the steel pipe column 301 to ensure that the steel pipe column 301 maintains the correct position during the pouring process; the positioning steel hoop 306 can prevent the loss or displacement of materials such as concrete during the pouring process, thereby ensuring the stability and reliability of the retaining assembly;

[0034] Secondly, the connecting block 304 is plugged into the connecting sleeve 302 to connect the steel pipe column 301 and the pressure beam tube 303. When the slope land 2 is subjected to external force, the steel pipe column 301 and the pressure beam tube 303 will jointly bear the pressure and tension, and transmit the force to the outer walls of both sides of the cave arch body 1 through the connecting sleeve 302 and the connecting block 304, thereby enhancing the stability of the slope land 2. At the same time, since the outer diameter of the connecting block 304 is compatible with the inner diameter of the connecting sleeve 302, it can ensure that the steel pipe column 301 is stable. The stable installation of the steel pipe column 301 and the pressure beam tube 303 further improves the disaster resistance of the structure; in addition, since the steel pipe column 301 and the pressure beam tube 303 are arranged in parallel, the shape and quality of the slope land 2 can be better controlled, and the bearing capacity and disaster resistance of the land can be improved; the steel pipe column 301 and the pressure beam tube 303 that can be disassembled and assembled at will are convenient for transportation and storage, which can save space and reduce costs; during the on-site construction process, this design is also convenient for installation and adjustment, which can improve construction efficiency and reduce costs;

[0035] Finally, the fixed ground nails 4 are passed through the assembly holes 5 from the outside to the inside to connect with the slope land 2 to improve the supporting capacity and stability. The design of the assembly holes 5 allows the fixed ground nails 4 to be easily installed and disassembled, which can be adjusted and optimized according to actual needs. For example, fixed ground nails 4 of different lengths and diameters can be selected according to the characteristics and requirements of the slope land 2 to adapt to different terrains and land conditions.
