When the seawater is high tide, the side of the blade 24 with the protrusion 25 will be impacted head-on, and the blade 24 will rotate inside the groove 23. Then the mud and sand carried by the high tide will fall into the riprap layer 12 through the groove 23.

[0033] In one embodiment provided by the present invention, Figure 4 As shown, a slope protection cushion layer 18 is provided on one side of the top of the concrete layer 14, a sea-facing slope protection 19 is provided on one side of the top of the concrete layer 14, and a grass layer 20 is planted on the top of the sea-facing slope protection 19.

The vegetation coverage rate should be above 40%, and the plants planted in the structure composed of the riprap layer 12 and the grid plate 13 are selected to be waterlogged and salt-tolerant plants, and the vegetation coverage rate should be above 30%. The sea-facing slope of the seawall at this location does not directly face the open sea, and is suitable for planting herbaceous plants with underdeveloped roots and stems. In the seawall that allows over-the-wave, reinforcement or blocks can be used to strengthen its protection. The top of the bottom plate 9 A sub-dike 21 is cast on the outer wall of one side, and the sub-dike 21 is in contact with the concrete layer 14 and the seaward side slope protection 19. The riprap layer 12 adopts one or more of natural stones and artificial blocks. The artificial blocks mainly include: fence panels, four-legged cones, four-legged hollow squares, twisted I-shaped blocks, and twisted W-shaped blocks. The foot protection 11 adopts prefabricated concrete blocks. The seaward side slope protection 19 adopts one of conventional hollow hexagonal nut blocks and frames. The concrete layer 14 is composed of a mixture of fill, crushed stone and concrete. The wave-breaking wall 16 is composed of concrete, reinforced concrete, prefabricated reinforced concrete columns plus prefabricated concrete slabs and mortar-laid block stone structures. The core-coated cement fiberboard 22 is made of cement and plastic.

[0034] In another embodiment provided by the present invention, Figure 3 As shown, the reinforcement component 2 includes a pad 4, and a plurality of anchor rods 5 are arranged at the bottom of the pad 4. The anchor rods 5 can be made by grouting or directly adopt prefabricated socket rods. The anchor rods 5 penetrate into the embankment 1, which can improve the connection strength between the slope protection component 3 and the embankment 1, so that the firmness of the slope protection component 3 on the embankment 1 is improved, and the probability of the seawall being eroded and displaced is reduced. A permeable plate 6 is arranged on the outer wall of one side of the top of the pad 4. The permeable plate 6 is made of permeable concrete and has strong water permeability. The embankment 1 is filled with a plurality of drainage pipes 8, and the permeable plate 6 is arranged at one end of the plurality of drainage pipes 8. A plurality of limit grooves 7 are provided on the outer wall of one side of the top, a plurality of limit blocks 10 are provided on the outer wall of the bottom of the bottom plate 9, and the limit blocks 10 are clamped in the limit grooves 7. A plurality of water collecting tanks 26 are provided inside the embankment 1. When it rains, water on the top 17 of the embankment will penetrate into the concrete layer 14 and the bottom plate 9, and then penetrate into the permeable board 6. The permeable board 6 will intercept the mud and sand. At the same time, due to the impermeability of the pad 4, the infiltrated water will flow into the water collecting tank 26, and then be discharged from the seawall through the drain pipe 8. One side of the bottom of the permeable board 6 is located above the water collecting tank 26, and the drain pipe 8 is plugged into one side of the inner wall of the water collecting tank 26.

[0035] Working principle: When constructing a seawall, multiple anchor rods 5 can be inserted into the embankment 1 first, and then the prefabricated pad 4 can be placed on the embankment 1, so that the embankment 1 and the anchor rods 5 are combined together. Subsequently, workers pour concrete according to construction requirements to form structures such as the concrete layer 14, the foot guard 11, and the bottom plate 9. Then, the prepared riprap layer 12 material is poured on the bottom plate 9 to form the riprap layer 12. Subsequently, the prepared grating plates 13 are sequentially spliced ​​on the riprap layer 12, and the prepared plants are planted on the riprap layer. On the structure composed of the stone layer 12 and the grid plate 13, the prepared back-to-sea slope 19 is subsequently arranged on the concrete layer 14, and then the grass layer 20 is planted in the back-to-sea slope 19, and then repaired to complete the construction of the seawall. When the seawater rises and falls and impacts the seawall, the side of the blade 24 with the protrusion 25 will be impacted positively during the process of high tide, and the blade 24 will rotate inside the groove 23, and then the silt carried by the high tide will fall into the inside of the riprap layer 12 through the groove 23, and then the low tide When the tide is low, the seawater will fall and exert force on the other side of the blade 24, so that the structure composed of the blade 24 and the protrusion 25 is stuck in the groove 23, so as to prevent a large amount of mud and sand in the riprap layer 12 from flowing with the seawater when the tide is low, thereby reducing the speed of soil erosion on the sea side of the seawall, reducing the number of times workers replenish sand, and greatly reducing the cost of seawall maintenance. In addition, the design of the anchor rod 5 can improve the connection strength between the slope protection component 3, the reinforcement component 2 and the embankment 1, so that the firmness of the slope protection component 3 on the embankment 1 is improved, and the seawall is reduced from being washed away. The probability of displacement is reduced, and when it rains, the water on the top 17 of the embankment will penetrate into the concrete layer 14 and the bottom plate 9, and then penetrate into the permeable board 6. The permeable board 6 will intercept the mud and sand in this process, so that only water can penetrate into the permeable board 6. At the same time, due to the impermeability of the pad 4, the infiltrated water will flow into the sump 26, and then the water inside the sump 26 will be discharged from the seawall through the drain pipe 8. One side of the bottom of the permeable board 6 is located above the sump 26, and a drain pipe 8 is inserted on one side of the inner wall of the sump 26. The drain pipe 8 is made of cement pipe or plastic pipe.
