DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] By Figures 1 to 4The present invention includes a galvanized steel mesh 1, a geogrid 2 fixedly installed on one side of the lower part of the galvanized steel mesh 1, a diagonal brace 3 fixedly installed between the galvanized steel mesh 1 and the geogrid 2, a gravel filling layer 4 filling the space between the galvanized steel mesh 1 and the geogrid 2, a pre-embedded pipe 5 welded to the upper part of the galvanized steel mesh 1, a pre-embedded box 6 fixedly installed at one end of the pre-embedded pipe 5, a shaft 7 provided inside the pre-embedded pipe 5, four bushings 8 rotatably installed on the surface of the shaft 7, and the surfaces of the four bushings 8 being fixedly connected to the inner wall of the pre-embedded pipe 5. Four support sleeves 26 are fixedly installed parallel to each other at equal intervals on the wall. The four support sleeves 26 can effectively support the pre-embedded pipe 5 and prevent the pre-embedded pipe 5 from deforming during construction and covering. One end of the shaft 7 extends to the outside of the pre-embedded pipe 5 and is fixedly installed with a handwheel 25. The other end of the shaft 7 is provided with a transmission component. Two insertion rods 19 are symmetrically arranged inside the pre-embedded box 6. The transmission component is connected to the two insertion rods 19. When the shaft 7 rotates, the power is output to the two insertion rods 19 through the transmission component, so that the two insertion rods 19 are inserted into the soil.

[0019] During construction, the operators connect the galvanized steel mesh 1, geogrid 2, and diagonal brace 3, then weld the pre-embedded pipe 5 to the upper part of the galvanized steel mesh 1. Next, the crushed stone filling layer 4 is filled between the galvanized steel mesh 1 and the geogrid 2. Then, a reverse filter geotextile is laid on the side of the crushed stone filling layer 4 away from the galvanized steel mesh 1, and ecological bags are stacked on the side of the galvanized steel mesh 1 away from the crushed stone filling layer 4. Finally, backfill soil and spread it so that the soil covers the pre-embedded box 6. After the soil is spread, the operator rotates the handwheel 25 to drive the shaft 7 to rotate inside the four bushings 8. When the shaft 7 rotates, it drives the transmission component to operate. When the transmission component operates, it drives the two insertion rods 19 to be inserted into the soil, thereby improving the tie strength of the upper part of the galvanized steel mesh 1. This results in high tie strength at the upper part of the reinforced soil retaining wall, making it less likely to cause damage to the upper part of the support structure.

[0020] The transmission assembly includes a threaded rod 9, which is fixedly installed at the other end of the shaft 7. A threaded sleeve 10 is threadedly connected to the surface of the threaded rod 9. Slider blocks 11 are fixedly installed on both the upper and lower sides of the threaded sleeve 10. Slide grooves 12 are opened on the inner walls of both sides of the upper side of the embedded pipe 5. The two sliders 11 are slidably installed inside the two slide grooves 12. One end of the threaded sleeve 10 extends into the interior of the embedded box 6 and is fixedly installed with a pushing block 13. Arc-shaped grooves 14 are opened on both the upper and lower sides of the pushing block 13. Limiting strips 15 are fixedly installed on both the front and rear sides of the pushing block 13. Limiting grooves 16 are opened on both the front and rear inner walls of the embedded box 6. Strip 15 is slidably installed inside the two limiting grooves 16; one end of the pushing block 13 is tightly attached to two contact blocks 17, and a connecting plate 18 is fixedly installed on the side of the two contact blocks 17 that is far away from each other. A plug rod 19 is fixedly installed on the side of the two connecting plates 18 that is far away from each other. Sliding sleeves 21 are fixedly installed on the front and rear sides of the two connecting plates 18 through connecting strips 20. Sliding rods 22 are inserted into the inside of the sliding sleeves 21. One end of the sliding rods 22 is fixedly connected to the inner wall of the pre-embedded box 6 through a connector 23. Springs 24 are sleeved on the surface of the sliding rods 22. The two ends of the four springs 24 are fixedly connected to the sliding sleeves 21 and the connectors 23 respectively.

[0021] When shaft 7 rotates, it drives threaded rod 9 to rotate. When threaded rod 9 rotates, it drives threaded sleeve 10 to move. When threaded sleeve 10 moves, it drives slider 11 to slide inside slide groove 12, increasing the stability of threaded sleeve 10 during movement. When threaded sleeve 10 moves, it drives pushing block 13 to move. When pushing block 13 moves, it drives limiting strip 15 to slide inside limiting groove 16, increasing the stability of pushing block 13 during movement. When pushing block 13 moves, it pushes two contact blocks 17 to move back to back. When two contact blocks 17 move back to back, they drive two connecting plates 18 to move back to back. When two connecting plates 18 move, they drive sliding sleeve 21 to slide on the surface of sliding rod 22 through connecting strip 20 and simultaneously squeeze two springs 24, thereby improving the stability of the movement of two connecting strips 20 while giving them an elastic reset effect. When two connecting plates 18 move back to back, they drive two insert rods 19 to insert into the soil.
