Description

Technical Field

[0001] The utility model relates to the technical field of retaining walls, in particular to a dry-build vegetation retaining wall. Background Art

[0002] The principle of ecological revetment is to ensure the basic functions of the water system, restore and maintain the natural landscape of the water system and the surrounding environment, improve the ecological environment of the water system, and enhance hydrophilicity. Based on the premise of protecting and creating a good living environment and natural landscape for organisms, a levee project with a set flood resistance strength is built, which is conducive to the improvement of the function and quality of the water system. The ecological revetment communicates the connection between the water system and the environment, making the function of the water ecosystem more perfect.

[0003] Most of the existing vegetation retaining walls usually only have a layer of sloped retaining walls near the river. Although this construction method is efficient and convenient, when there is heavy rainfall, mud, sand and gravel on the upper layer of the slope protection will inevitably be washed away by rainwater and flow from the outer surface of the retaining wall to the inside of the river. Some stones will even remain directly in the holes of the retaining blocks, which will not only block the normal drainage holes, but also hinder the growth of vegetation inside.

[0004] Therefore, it is necessary to provide a dry-build vegetation retaining wall to solve the above technical problems. Utility Model Content
