[0002] At present, river ecological restoration refers to the use of ecosystem principles and various methods to repair the biological communities and structures of damaged water ecosystems, rebuild healthy aquatic ecosystems, repair and strengthen the main functions of water ecosystems, and enable the ecosystem to achieve a virtuous cycle of overall coordination, self-sustaining and self-succession.

[0003] Existing ditch slope protection structures are mostly made of concrete. In order to prevent the plants attached to the surface of the slope protection structure from falling off, planting platforms are often set on the inner surface to ensure the good growth of the plants. At the same time, in order to prevent the ditch slope from becoming flat and damaged, metal mesh is often laid on the inner surface for reinforcement. However, the following problems exist:

[0004] In actual application, the existing river ecological ditch structure is unable to effectively filter and purify water quality. Secondly, after the plants are planted on the planting platform, the water flows there and flushes them, which cannot effectively ensure the growth stability of the plants. In addition, the metal mesh used to reinforce the ditch is difficult to ensure its own stability when it is washed by water in actual situations, and the actual reinforcement effect needs to be improved.

[0005] Therefore, the utility model proposes an ecological ditch structure for river channel restoration. Utility Model Content
