Riverway ecological embankment and construction method thereof

Abstract

The invention relates to the technical field of environment protection, and discloses a riverway ecological embankment and a construction method thereof. The riverway ecological embankment comprises atreatment area, a drainage assembly and a transition area. The treatment area comprises a first slope, a groove and a first barricade, all of which are sequentially arranged along a riverway side slope. A first containing area is formed among the first slope, the groove and the first barricade. A first anti-seepage layer, a first adsorption filter layer, a first water-permeable layer and an antiskid layer are sequentially laid at the bottom of the first containing area from bottom to top. One end of the drainage assembly is located in the first adsorption filter layer, and the other end of the drainage assembly is located in the first containing area. A second adsorption filter layer and a second water-permeable layer are sequentially laid on the side, close to the first containing area,of the first barricade. The first containing area is filled with a bottom mud layer. The riverway ecological embankment has the beneficial effects that dredging bottom mud is used for riverway embankment materials after being treated on the spot and meanwhile serves as a plant and microorganism growth matrix, and resource utilization of the dredging bottom mud is achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a river ecological revetment and a construction method thereof. Background technique [0002] With the continuous development of industry, a large amount of industrial wastewater is secretly discharged, leaked and substandard discharge, and domestic sewage is discharged directly, resulting in serious black and smelly river water, which seriously affects the utilization of water resources and human life and health. [0003] The bottom mud of rivers and lakes contains a large amount of cohesive soil, organic matter, nutrient salts and refractory substances, etc. These pollutants deposited in the bottom mud will release pollutants to the water body under the complex actions of physics, chemistry and biology, and destroy aquatic life. ecosystem. For the removal of polluted river and lake sediments, at present, mechanical excavation is mainly used, and then transport...

AI Technical Summary

Problems solved by technology

However, the cost of dredging sediment transportation is high, and it is easy to cause secondary pollution. At the same time, it is a waste of land resources due to the large amount of dredged sediment, difficulty in drying, difficult treatment and disposal, large land occupation, and long time consumption.
