Slope-type ecological embankment

Abstract

The invention discloses a slope-type ecological embankment. The slope-type ecological embankment is formed by arranging a geotextile inverted layer (3), a porous concrete revetment, a plant planting tank foot protection and a hygrophyte in sequence on the basis of the original stable structure slope surface (5), wherein the stable structure slope surface (5) is of undisturbed soil with a stable structure; the geotextile inverted layer (3) is a layer of water permeability non-woven geotextile; the porous concrete revetment is paved by a single layer globular complex made of porous concrete materials; the plant planting tank foot protection is set at the position where a slope toe is connected with a river bottom; the hygrophyte is a plant planted in the porous concrete revetment and the plant planting tank. The slope-type ecological embankment is stable and safe in structure, and simultaneously has functions of purifying water quality of river and constructing a river wall ecosystem.

Description

(1) Technical field: [0001] The invention relates to a river environment treatment technology, more specifically a slope type ecological embankment. (two) background technology: [0002] The embankment of a river is a transition zone where land and water intersect, and has a significant edge effect. The embankment in the natural state is often rich in species, high in productivity, and has active material, nutrient and energy flows. In terms of river governance, from the perspective of safety, the functions of flood discharge, drainage, and navigation are emphasized. The river channel is often dug deep, widened, straightened, and the embankment is hardened, but this will lead to deep grooves, shoals, sandbars and The disappearance of the river floodplain destroys the hydrological and ecological connection between the river bank and the river bed. Vegetation does not grow on the river bank and the river bottom. The function of the river bank to filter the surface runoff of t...
