Multi-stage purification landscape structure along river slope and construction method

Abstract

The invention belongs to the technical field of environmental engineering, and discloses a multi-stage purification landscape structure along a river slope and a construction method. The multi-stage purification landscape structure along the river slope is provided with a first-stage filtration layer, a second-stage filtration layer and a third-stage filtration layer; the inner side of the first-stage filtration layer is filled with a gravel layer, a permeable brick layer is laid at the upper side of the gravel layer, the second-stage filtration layer is located at the downstream of the first-stage filtration layer, a greening groove is built in the surface of the second-stage filtration layer, and a main sculpture is built at the side face of the greening groove; the third-stage filtration layer is located at the downstream of the second-stage filtration layer, and plants having higher absorption capacity for nitrogen and phosphorus are planted on the surface of the third-stage filtration layer. The multi-stage purification landscape structure along the river slope has the advantages that the gravel layer of the first-stage filtration layer can filter and block polluted particlesin the water flow, so that the influence on the filtration effect of the filtration layers at the downstream is avoided; the multi-stage slope filters the water flow of the river way, so that the pollution source of the slope can be sufficiently purified, the pollutants in the rainwater are removed, and unpurified water is prevented from entering the river way.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to a multi-stage purification landscape structure and construction method for slope land along a river. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: a river may be a symbol of a city. In the growing urban development, there are more high-rise buildings and less birds and flowers. A river carries the regional culture, politics, and economy. The memory of development, while the urban space transformation must not only reflect the development process and functional organization process of the space, but also show specific humanistic feelings and cultural heritage; the current landscape along the slopes along the river has no layers and single functions, so it cannot be a place for people's leisure and entertainment. The place cannot better reflect the cultural characteristics of a city, and ...

AI Technical Summary

Problems solved by technology

[0004] (1) At present, the landscape along the slopes along the river has no layers and single functions, so it cannot become a place for people's leisure and entertainment, and cannot better reflect the cultural characteristics of a city

[0005] (2) At present, the sloping land along the river does not have the purification function, and it is easy to cause the pollutants in the water to flow into the river water body, causing pollution to the river water body
