Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ecological retaining walls, in particular to an ecological vegetation concrete retaining wall. Background Art
[0002] In recent years, retaining walls, as a kind of building used to support steep slopes to maintain soil stability, have been effectively and widely used in engineering construction fields such as road engineering and railway engineering. As the requirements for sustainable development in urban construction are improved and upgraded, retaining walls have also had higher requirements in terms of environmental protection and ecological beautification. After the construction of existing concrete retaining walls is completed, the hardened and solid concrete surface is directly exposed to the outside, which makes it difficult to grow green plants and has poor ecological improvement effects. In order to achieve the requirements of ecological landscape, the existing technology only uses external planting troughs, planting bags, etc., which is not only complicated to construct, but also often has problems such as poor installation, easy damage by external environmental forces, and difficulty in later maintenance. Therefore, the development of an ecological vegetation concrete retaining wall that is simple to construct, stable in quality, and reasonable and effective, which not only realizes the protective function but also improves the ecological environment, is a problem that needs to be urgently solved by technical personnel in this field. Utility Model Content
[0003] To achieve the above-mentioned purpose, the utility model provides an ecological vegetated concrete retaining wall, characterized in that the structure includes a filter layer, a retaining wall structure, a steel mesh, a vegetated concrete layer, and a grass layer, wherein the retaining wall structure includes reserved steel bars and reserved intermittent maintenance pipes.
[0004] Furthermore, an anti-filter layer is arranged behind the retaining wall structure.
[0005] Furthermore, intermittent maintenance pipes are reserved in the retaining wall structure.
[0006] Furthermore, steel bars are reserved for the retaining wall structure.
[0007] Furthermore, the outside of the reserved steel bars of the retaining wall structure is welded to the steel mesh.
[0008] Further, vegetated concrete is provided.
[0009] Furthermore, the green concrete is sprayed onto the wall surface of the retaining wall structure to form a green concrete layer.
[0010] Furthermore, grass seeds are sown on the vegetation concrete layer to form a grass planting layer.
[0011] The beneficial effects of the utility model are:
[0012] The anti-filtration layer can allow the water in the soil behind the wall to be discharged smoothly into the intermittent curing pipe, and can protect the soil from flowing into the intermittent curing pipe along with the water.
[0013] The reserved intermittent maintenance pipe can lead the accumulated water behind the wall and the water in the soil to the front of the wall, which can not only play a role in daily maintenance of the wall vegetation of the retaining wall structure, but also can intermittently stimulate the water-stimulated nitrogen, phosphorus and potassium compound fertilizer in the vegetation concrete to extend the growth period of vegetation. In addition, the intermittent maintenance pipe can also serve as a drainage hole of the retaining wall.
[0014] The reserved steel bars are welded and fixed to the steel mesh, so that the steel mesh and the retaining wall structure can be more stably connected.
[0015] The steel mesh can well fix the vegetation concrete layer, and effectively prevent the concrete from falling off, breaking, etc. during and after spraying.
[0016] The vegetation concrete layer has the characteristics of water permeability and the ability to provide nutrients for vegetation, so that grass seeds can be quickly planted in a large area through spraying and grow effectively, thereby achieving full coverage of vegetation on the wall surface.
[0017] The grass planting layer can not only effectively improve the ecological landscape of the retaining wall and beautify the environment, but also effectively reduce the scouring of the retaining wall structure by a large amount of rainwater during the rainy season, and reduce the impact on the retaining wall, side ditch and other structures.
