Technical Field
[0001] This utility model relates to the field of water conservancy and embankment technology, specifically a embankment slope protection structure. Background Technology
[0002] In the process of river embankment management, retaining walls are generally used for embankments with steep slopes. These retaining walls are typically made of rigid masonry structures such as concrete or masonry. However, these structures are prone to cracking and fracture due to uneven geological settlement. River water seeps into the soil behind the wall through these cracks, and due to issues such as undercurrent and contact erosion, the soil behind the wall is often eroded, leading to safety problems such as embankment crest subsidence and landslides. Furthermore, rigid structures such as concrete or masonry are not easily greened, resulting in poor ecological performance.
[0003] Therefore, in view of the above situation, there is an urgent need to provide a dike slope protection structure to overcome the shortcomings in current practical applications. Utility Model Content

[0034] like Figures 1-4 As shown, the riverbank protection slope structure of this utility model, for the self-embedded retaining wall 1, firstly, a foundation 3 is constructed, and then self-anchoring bricks 4 are interlocked and laid. Crushed stone 5 and geotextile 6 are placed behind the self-anchoring bricks 4 as a filter layer. Multiple layers of geogrid 2 are installed in the soil behind the self-embedded retaining wall 1, and the geogrid 2 is connected to the self-anchoring bricks 4 to prevent the retaining wall from overturning and to increase the anti-sliding performance of the embankment slope soil 7. The embankment protection slope adopts a multi-stage stepped self-embedded retaining wall 1 structure. The gaps between the self-anchoring bricks 4 are filled with planting soil 8 containing grass seeds, and ecological vegetation is planted on the platforms between the multi-stage stepped self-embedded retaining walls.
[0035] In a preferred embodiment, the self-embedded retaining wall 1 has a wall height H1 of 2-3m and a platform width B1 of 5-10m. In practical applications, the number of steps in the self-embedded retaining wall 1 can be determined according to the height of the embankment; in a preferred embodiment, 2-5 steps are used.
[0036] The foundation 3 is a concrete structure in the shape of an "L". In the preferred embodiment, the height H2 is not less than 0.4m and the width B2 is not less than 0.6m.
[0037] The self-anchoring brick 4 is made of concrete. In a preferred embodiment, its length A is 0.6m, width B is 0.4m, and height C is 0.3m. The top surface of the self-anchoring brick 4 has a groove with a depth H3 of 0.1m and a width B3 of 0.15m. The groove is located 0.1m from the edge L1. The bottom surface of the self-anchoring brick 4 has two protruding teeth. The first protruding tooth is 0.05m from the edge L2, with a height H4 of 0.1m and a width B4 of 0.15m. The second protruding tooth is 0.1m from the first protruding tooth L3, with a height H4 of 0.1m and a width B5 of 0.1m.
[0038] In the preferred embodiment, the self-anchored bricks 4 are interlocked between the upper and lower layers, and a 50mm wide gap B6 is left between the left and right sides, which is filled with planting soil 8 containing grass seeds.
[0039] In a preferred embodiment, the crushed stone 5 has a particle size distribution of D = 50-200 mm.

After every 1-2 layers, the gravel behind the wall is filled, the geotextile is laid, and the soil behind the wall is filled and compacted. Finally, a layer of geogrid is laid on top, and the geogrid is connected to the self-anchored bricks. The layering is carried out in a cyclical manner until the construction of the retaining wall at that level is completed. According to the height of the embankment, a multi-level stepped retaining wall is implemented. Finally, the entire embankment slope protection structure is completed.
