The embankments in cities and towns mostly use concrete or mortar-masonry retaining walls, which cannot grow plants, have a gray-black appearance, and lack ecological characteristics. The smooth surface of the retaining wall reduces the roughness of the river course and increases the water flow speed, which has a greater impact on the survival and reproduction of aquatic organisms. The invention solves the problems of unecological problems of the built retaining wall. The invention includes a concrete or mortar-masonry retaining wall and a crescent-shaped ecological trough. The water-facing surface of the retaining wall is a steep elevation. The ecological troughs are anchored on the water-facing surface of the retaining wall. . The ecological trough includes short piles, troughs for planting plants and for hands and feet. The short pile includes an inserting part inserted into the retaining wall and a butting part protruding from the retaining wall. The groove body is fixedly connected to the butting part, the lower part of the groove body is provided with drainage holes, and the outer surface of the inserting part is provided with an anticorrosive layer. An irrigation pipe is set in the ecological tank and landscape plants are planted. Engineering examples show that the present invention has a large application market and has significant economic, social and ecological benefits.
This invention was selected and participated in the 2019 China Innovation and Entrepreneurship Achievements Fair, was written into the "Guangdong Province 2020 Water Conservancy Science and Technology Promotion Guide", and was funded by the Guangdong Provincial Water Conservancy Science and Technology Innovation Project.
