Ecological slope protection structure of river course

Technical Field

The utility model relates to a river channel ecological slope protection structure. Is applicable to the technical field of urban river side slope protection.

Background

At present, the slope of the side slope of a plurality of urban river channels in China is large, and the phenomenon of water and soil loss is easy to occur. In order to prevent and treat water and soil loss, a common measure is to adopt a hard slope protection. The hard revetment can play a role in water and soil conservation and flood control, but lacks green vegetation to enhance ecology of the river. The grass planting slope protection is a good transition area, and is combined with a hydrophilic pavement arranged in a river channel, so that a good place for rest, entertainment and body building is created for citizens, the comprehensive service function of the urban river channel is improved, and a happy river at the entrance of the citizen is created. Meanwhile, the existing river channel revetment is easy to cause soil loss of grass planting, revetment planting and soil erosion of the river channel due to on-shore rain wash, and even the whole revetment collapses. Meanwhile, due to long-term erosion of water flow in the river channel, vegetation and soil planted on the protection slope can be taken away.
