[0003] In the prior art, the ecological river embankment structure is usually in the form of fixed foot and slope planting grass to prevent the phenomenon of soil erosion caused by the impact of river flow on the soil on both sides of the river bank. However, the existing ecological river embankment structure still has the following defects: 1. The typical bank slope protection structure lacks the conditions for fish and amphibian habitat and reproduction. 2. A large amount of excavation of earth and stone is required to ensure the stability of the foundation and prevent erosion, which is high in investment. 3. Before the grass seeds grow, rainwater erosion and flood period will cause soil erosion. SUMMARY
[0004] The utility model aims to provide an ecological river embankment structure. The structure not only has the functions of flood control and drainage of traditional river embankments, but also integrates the concept of ecological protection. Through the construction and management of the river embankment, the restoration and protection of the river ecosystem are promoted.
[0005] The technical scheme of the utility model is an ecological river embankment structure, which comprises a backwater side pile body arranged at the slope toe and vertically inserted into the river channel, a water side pile vertically inserted into the river channel outside the backwater side pile body, a hydrophilic platform supported by the top of the backwater side pile body and the water side pile, a fish breeding place formed in the river channel between the backwater side pile body and the water side pile, and aquatic plants planted in the river channel where the fish breeding place is located.
[0006] In the aforementioned ecological river embankment structure, the backwater side pile body comprises backwater side long piles and backwater side short piles arranged in close proximity.
[0007] In the aforementioned ecological river embankment structure, the interval between two adjacent water side piles forms a fish passage, the top of the plurality of water side piles supports a connecting crossbar, and the hydrophilic platform is supported on the connecting crossbar.
[0008] In the aforementioned ecological river embankment structure, the slope between the slope toe and the embankment top is covered with cultivated soil, a coconut fiber carpet is laid on the surface of the cultivated soil, nutrient soil is covered on the coconut fiber carpet, and vegetation is planted in the nutrient soil.
[0009] In the aforementioned ecological river embankment structure, the coconut fiber carpet is fixed on the surface of the cultivated soil by U-shaped nails.
[0010] The ecological river embankment structure has the advantages that compared with the prior art, the ecological river embankment structure has high adaptability, can be implemented in various geological conditions, saves the excavation amount, and thus reduces the engineering investment cost.

DETAILED DESCRIPTION
[0014] The utility model is further described below in combination with the drawings and examples, but is not taken as the basis for limiting the utility model.
[0015] The embodiment of the utility model: a kind of ecological river embankment structure, including being set in slope toe, vertical insertion backwater side pile body in river channel, water side pile 2 is vertically inserted in the river channel outside the backwater side pile body, backwater side pile body and water side pile 2 top are supported with hydrophilic platform 3, the river channel between backwater side pile body and water side pile 2 forms fish breeding place 13, aquatic plant 14 is planted in the river channel where fish breeding place 13 is located.
[0016] The hydrophilic platform 3 is 0.2-0.4m higher than the perennial water level 1, the design not only satisfies the demand of people on beauty in visual, auditory and tactile aspects, but also enables people to better feel the charm of water and increases the interaction between people and water. By planting suitable aquatic plants 14, the water self-purification ability is enhanced, and a good living and breeding environment is provided for the organisms. The fish breeding place 13 is set to simulate the natural environment and provide suitable habitat for fish and amphibians. The breeding place is helpful to protect and increase the resources of fish and amphibians. The backwater side pile body is provided, the backwater side pile body is designed in the form of pile type fixed foot to reduce the excavation amount, is suitable for silt, soil layer, gravel, rock foundation and various geological conditions, and has wide adaptability.
[0017] The backwater side pile body comprises the backwater side long pile 4 and the backwater side short pile 5 arranged in alternation, the backwater side long pile 4 is mainly used to satisfy the slope stability, and the backwater side short pile 5 is mainly used to block soil. The backwater side long pile 4 and the backwater side short pile 5 are arranged in parallel connection and jointly guarantee the stability of the hydrophilic platform 3 together with the water side pile 2.
