Description

Technical Field

[0001] The utility model belongs to the technical field of water environment management, and specifically relates to a vegetated concrete river channel slope protection structure. Background Art

[0002] In the context of the continuous development of urbanization, ecological problems have become increasingly prominent, and the situation of river water pollution is severe. Traditional river water treatment technologies have good short-term effects, but they are often only a temporary solution for water self-purification and water ecology. Not only are the treatment costs high, but there is also a high possibility of secondary pollution to the environment.

[0003] As the main protective structure of the river, river slope protection can ensure the safety of the river, protect the river ecology and maintain water resources. Although the traditional river slope protection method is strong, it hinders the material exchange between the water body and the soil, has poor ecological benefits, and can no longer meet the needs of the sustainable development of the current ecological environment. River slope protection should not only be practical, but also aesthetically pleasing and harmonious with the environment. Vegetated concrete slope protection has good anti-scouring and anti-filtration performance, high strength and stable structure. Applying it to river slope protection can not only beautify the environment, but also consolidate soil and retain water, achieving multiple improvements in ecological benefits, economic benefits and safety benefits. However, the conventional vegetated concrete slope protection has limited water purification capacity and cannot achieve the purpose of purifying water. Therefore, there is an urgent need for a vegetated concrete river slope protection that can remove water pollutants. Utility Model Content

[0037] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.
