A number of anchor rods are pre-embedded and installed in the upper half of the permeable concrete layer. The anchor rods pass through the backfill soil layer and are inserted into corresponding positioning holes opened on the grass planting bricks. Grass plants are planted in the holes in the middle of the grass planting bricks. A concrete retaining wall is arranged at the bottom of the permeable concrete layer. Drainage channels are opened on the concrete retaining wall, and one-way valves are installed in the drainage channels.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] The grass-planting bricks of the utility model can be connected with the permeable concrete layer through anchor bolts, which can improve the laying firmness of the grass-planting bricks, reduce the probability of the grass-planting bricks being washed into the river during use, and further better protect the safety of the plants in the grass-planting bricks and improve the stability of the bank protection structure.
[0013] 2. By setting the water-blocking layer, drain pipe and drainage channel, the water-blocking layer is a geomembrane, which can block the water body seeping into the plain soil layer and discharge it to the concrete retaining wall through the drain pipe, and then discharge it to the river through the drainage channel. In this way, the anti-seepage ability of the bank protection can be improved, and the safety of the bank protection can be further improved. Description of the drawings

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1 , Figure 2 and Figure 4 In the embodiment of the utility model, a permeable vegetation concrete bank protection structure includes a plain soil layer 1, a water retaining layer 2 and a permeable concrete layer 4. The surface of the plain soil layer 1 is compacted into a stepped shape. The stepped shape can use the weight of the crushed stone layer 3 to firmly press the water retaining layer 2 on the plain soil layer 1. The bottom edge of the water retaining layer 2 is embedded between the permeable concrete layer 4 and the concrete retaining wall 6. In this way, the water retaining surface of the water retaining layer 2 can be larger, and the water accumulated at the bottom of the crushed stone layer 3 can be blocked. The plain soil layer 1 is provided with a water retaining layer 2, the water retaining layer 2 is provided with a crushed stone layer 3, the crushed stone layer 3 is provided with a permeable concrete layer 4, the permeable concrete layer 4 is provided with a backfill soil layer 5, and the backfill soil layer 5 is provided with grass-planting bricks 7. A plurality of anchor rods 8 are pre-buried in the upper half of the permeable concrete layer 4, and the anchor rods 8 pass through the backfill soil layer 5 and are plugged into the corresponding positioning holes 13 on the grass-planting bricks 7. After the permeable concrete layer 4 is poured and before the permeable concrete layer 4 is solidified, a plurality of anchor rods 8 are inserted into the permeable concrete layer 4. The length of the anchor rods 8 extending out of the permeable concrete layer 4 is 30-35 cm, and the length of the anchor rods 8 extending into the permeable concrete layer 4 is 3-5 cm. When laying the grass-planting bricks 7, the positioning holes 13 on the grass-planting bricks 7 are aligned with the anchor rods 8 for installation. Grass plants 9 are planted in the middle holes of the grass-planting bricks 7. A concrete retaining wall 6 is provided at the bottom of the permeable concrete layer 4, and the concrete retaining wall 6 is ordinary concrete.
[0021] When in use, the plain soil layer 1 is first processed into a stepped shape by engineering machinery and then compacted. After compaction, at least two layers of water retaining layers 2 with a single layer thickness of not less than 0.5 cm are laid thereon, and then a crushed stone layer 3 is laid on the water retaining layer 2, and a permeable concrete layer 4 with a thickness of 30-50 cm is laid on the crushed stone layer 3. The bottom of the permeable concrete layer 4 is formed into a concrete retaining wall 6 by casting concrete through formwork, and then a 25-30 cm thick backfill soil layer 5 is set on the permeable concrete layer 4, grass bricks 7 are laid on the backfill soil layer 5, and grass plants 9 are planted in the middle of the grass bricks 7.
[0022] See also Figures 1-3, a drainage channel 11 is provided on the concrete retaining wall 6, and a check valve 12 is installed in the drainage channel 11. The check valve 12 can prevent the water in the river from flowing back into the concrete retaining wall 6 through the drainage channel 11. A drain pipe 10 is installed at the bottom of the permeable concrete layer 4. One end of the drain pipe 10 extends into the gravel layer 3, and the other end passes through the backfill soil layer 5 and is arranged on the concrete retaining wall 6;
[0023] The drainage channel 11 is inclined, and the lower end of the drainage channel 11 is located on the water-facing side of the concrete retaining wall 6. This design can quickly discharge the water on the concrete retaining wall 6 into the river.
[0024] When it rains, the excess rainwater on the bank will successively pass through the backfill soil layer 5, the permeable concrete layer 4 and the gravel layer 3 to reach the water retaining layer 2. After the water retaining layer 2 blocks the water, it is discharged to the concrete retaining wall 6 through the drain pipe 10, and then discharged into the river through the drainage channel 11.
