Description

Technical Field

[0001] The utility model relates to the technical field of slope retaining walls, in particular to a retaining wall applicable to high and steep slopes in narrow sites. Background Technique

[0002] The slope is washed by rainwater. The soil body absorbs water and will expand and deform, and even landslides may occur, which has great potential hazards. The slope retaining wall is an important part of the slope protection project and is mainly used to support natural slopes, cut slopes or artificial fill slopes to maintain the stability of the soil body. The slope retaining wall refers to a structure that supports the subgrade filling or hillside soil body and prevents the filling or soil body from deforming and becoming unstable.

[0003] Common retaining walls for maintaining slopes need to pour concrete on site. The pouring of concrete takes a long time and consumes a lot of labor, resulting in a long construction time and low efficiency of the retaining wall, increasing the construction cost of the retaining wall.

The first retaining plate and the second retaining plate are fixedly connected to the frame plate through bolts, and mounting holes adapted to the bolts are provided on the sides of the first retaining plate, the second retaining plate and the frame plate. By providing bolts and mounting holes, it is convenient to quickly install and fix the first retaining plate and the second retaining plate to the frame plate respectively. By providing the frame plate, it is convenient to position and support the first retaining plate and the second retaining plate.

[0020] The upper surface of the bottom plate 1 is fixedly connected with a connecting plate 4. The front and back of the surface of the connecting plate 4 are fixedly connected with frame plates 5. The side of the frame plate 5 is fixedly connected with a first retaining plate 6. The top surface of the first retaining plate 6 is fixedly connected with a convex block 7. The top surface of the first retaining plate 6 is inserted with a second retaining plate 8. The side of the frame plate 5 is fixedly connected with a support rod 9. The bottom end of the support rod 9 is fixedly connected with a slope soil body 10. The surface of the bottom plate 1 is provided with backfill soil 11.

[0021] The surfaces of the first retaining plate 6 and the second retaining plate 8 are both provided with anchor bolts 20, and the anchor bolts 20 are inserted into the interior of the backfill soil 11. The frame plate 5, the first retaining plate 6 and the second retaining plate 8 are all placed obliquely, and the frame plate 5 is L-shaped. By setting the frame plate 5 to be L-shaped and placing the frame plate 5 obliquely, it is convenient to quickly position and install the first retaining plate 6 and the second retaining plate 8.

[0022] The bottom surface of the second retaining plate 8 is provided with a socket groove 12 adapted to the convex block 7. The side of the second retaining plate 8 is provided with a grouting hole 13, and the grouting hole 13 communicates with the socket groove 12.

[0023] The sides of the first retaining plate 6 and the second retaining plate 8 are both provided with bolts 14. The first retaining plate 6 and the second retaining plate 8 are both fixedly connected with the frame plate 5 through the bolts 14, and the sides of the first retaining plate 6, the second retaining plate 8 and the frame plate 5 are all provided with mounting holes adapted to the bolts 14.

[0026] Working principle: The backfill soil 11 buries the retaining wall bottom plate 1, increasing the stability of the retaining wall. The upper part of the retaining wall has a tendency to tilt towards the slope soil mass 10 under the influence of gravity, and can resist the earth pressure of the slope soil mass 10 deforming outwards. The anchor rod 20 is squeezed by the backfill soil 11, making the connection between the retaining wall and the backfill soil 11 tight. When the backfill soil deforms outwards, the friction force generated between the anchor rod 20 and the backfill soil 11 can offset part of the earth pressure. Thus, this retaining wall has a good effect on maintaining the slope.

[0027] First, dig a foundation pit on the ground, then place the bottom plate 1 and the connecting plate 4 as a whole in the foundation pit. Then fix the frame plate 5 on the surface of the connecting plate 4 through screws. The support rod 9 inserted into the slope soil mass 10 supports the frame plate 5 to prevent the frame plate 5 from toppling. Then use a crane to place the first retaining plate 6 closely on the side of the frame plate. Subsequently, fix the first retaining plate 6 to the frame plate 5 with bolts 14. Then place the stabilizing block 16. Subsequently, hoist the second retaining plate 8 and insert the convex block 7 into the socket 12 at the bottom of the second retaining plate 8. Pour concrete into the grouting hole 13. Then install the support plate 9 and the inclined rod 19. Then put the backfill soil 11 on the surface of the bottom plate 1. Finally, insert the anchor rod 20 into the backfill soil 11. This section of the retaining wall is completed. Thus, compared with the cast-in-place retaining wall on-site, this retaining wall applicable to high and steep slopes in narrow sites can be assembled, further improving the construction efficiency of the retaining wall.
