The steel concrete revetment is generally an L-shaped cantilever structure, with both the wall and the bottom plate made of steel concrete. Its towering bank slope breaks the ecological connection between the river channel and the land behind, blocks the survival channel of aquatic animals and amphibians, destroys the natural water ecology, and reduces biodiversity.

[0020] By adopting the above technical solution, the beneficial effects of the utility model include:
[0021] 1. Protecting biodiversity
[0022] Natural river channels and their banks are often excellent habitats for diverse organisms. However, with the intervention of urbanization and human construction activities, the vertical hard revetments built on both sides have greatly changed the original appearance and ecology, severed the ecological connection between the river channel and the land behind it, blocked the survival and migration channels of animals, greatly reduced biodiversity, and made the coastal waters no longer suitable for amphibians, birds and other organisms to inhabit, breaking the ecological balance. The ecological revetment created by the above-mentioned multi-level composite section type creates a suitable living environment for different organisms, meets the habitat needs of diverse organisms, and protects biodiversity while improving the river landscape.
[0023] 2. Improve water environment and ensure navigation safety
[0024] Traditional inland river revetments are mostly upright hard structures, with basically no water exchange channels between the river and the land behind, resulting in poor water ecological effects. After setting up the ecological revetment structure, the elevations of the front and rear walls of the ecological water tank are controlled to 50% cumulative frequency water level and 85% cumulative frequency water level, respectively, and water exchange holes are separated in the wall body. On the one hand, water exchange is enhanced to improve the water environment, and on the other hand, the water level is controlled to be suitable for biological survival. In addition, through natural techniques such as landscape stones and plants, the navigation boundaries of ships are marked, creating an ecological and safe navigation environment.

[0033] The aquatic habitat 1 is located on the water side and includes an ecological water tank structure 11. A pile foundation is arranged at the bottom of the ecological water tank structure. The pile foundation may include sheet piles 12 and square piles 13, wherein the square piles 13 are arranged at a position relatively closer to the river bank.
[0034] Landscape stones 14 are built in the front of the ecological water tank structure 11, and the front refers to the position relatively farther from the river bank. The landscape stones 14 have the functions of warning the navigation boundary for navigable ships, eliminating the energy of ship waves, and reducing the impact of water flow on the rear organisms. Ecological fish nests 15 and submerged plants 16 are set in the rear of the ecological water tank structure 11 for aquatic animals such as fish and shrimp to live.
[0035] The top elevation of the front wall of the ecological water tank structure 11 is controlled to be the 50% cumulative frequency water level; the top elevation of the rear wall of the ecological water tank structure 11 is controlled to be the 85% cumulative frequency water level, and the front water exchange hole 17 is separated in the front wall body, and the rear water exchange hole 18 is separated in the rear wall body, which can enhance water exchange and improve the water environment on the one hand, and control the water level to be suitable for biological survival on the other hand. The front wall refers to the wall of the ecological water tank structure 11 that is relatively farther away from the river bank. The rear wall refers to the wall of the ecological water tank structure 11 that is relatively closer to the river bank.
[0036] The lower layer of the front end of the amphibian and bird habitat 2 is paved with a vegetation net 21, the upper layer is covered with planting soil 22, and emergent plants 23 are planted, and blocks 24 are scattered; the rear end of the amphibian and bird habitat 2 is set with a sloped bank, and the sloped bank is sequentially provided with nut block slope protection 25, backfill soil 26, bagged gravel 27, and geotextile 28 from top to bottom. The amphibian and bird habitat 2 can provide habitats for amphibians such as frogs, salamanders, lizards, and birds. The top elevation of the amphibian and bird habitat 2 is controlled to be the 95% cumulative frequency water level; a pressure top 29 is set between the sloped bank and the terrestrial organism buffer zone 3.
[0037] The terrestrial biological buffer zone 3 is provided with grass 31, shrubs 32 and trees 33 arranged in a scattered manner for the terrestrial organisms to live in. The top elevation of the terrestrial biological buffer zone 3 is controlled as the flood control elevation.
[0038] In the utility model, the horizontal and vertical dimensions of the aquatic habitat zone 1, the amphibian and bird habitat zone 2, and the terrestrial buffer zone 3 can be set according to specific circumstances; in view of the fact that the amphibian and bird habitat zone is located between the aquatic habitat zone and the terrestrial buffer zone, it plays a connecting and transitional function, and generally its horizontal width is larger; in one embodiment, the horizontal width ratio of the aquatic habitat zone 1, the amphibian and bird habitat zone 2, and the terrestrial buffer zone 3 can be set as 1:2:1.
[0039] The utility model sets up ecological revetments in inland rivers, and successively sets up aquatic habitat zones, amphibian and bird habitat zones, and terrestrial buffer zones from water to shore, thereby providing habitat and living space for a variety of organisms, improving water ecology, and increasing biodiversity. At the same time, it also marks the navigation boundaries of ships and ensures navigation safety.
