[0009] Further, the plants in the grass seed area are arranged corresponding to the water level zoning to form a plant growth surface of the revetment structure. The grass seed area is filled with grass seed soil, and the clay area is filled with clay.

[0010] Further, the first end of the tie bar bypasses the corresponding drainage blind pipe unit to form a wrapped shape and is connected by a connecting rod, and the backfill soil is laid above the second end.

[0011] Further, a plurality of floating anti-collision structures are provided on the side of the wall panel away from the backfill soil, and the plurality of floating anti-collision structures are arranged at intervals along the length direction of the wall panel.

[0012] Further, the floating anti-collision structure includes:

[0014] A guide rail provided on the connecting plate and located on the side away from the wall panel;

[0015] A floating anti-collision pad, the upper and lower ends of which are slidably connected to the guide rail through buckle chains.

[0016] Further, the tie bars are unidirectional geogrids.

[0017] Advantages of the present utility model:
