External water interception and purification type urban river multi-element ecological embankment physical structural system

Abstract

The invention discloses an external water interception and purification type urban river multi-element ecological embankment physical structural system. The urban river multi-element ecological embankment physical structural system comprises a first-class platform ecological embankment physical structural system, a second-class platform ecological embankment physical structural system and a slope ecological embankment physical structural system which are organically combined on a river bank slope, wherein the first-class platform ecological embankment physical structural system is provided with an urban surface source sewage runoff collecting groove, a groove type ecological concrete building block, a vertical first-class retaining wall and the like; the second-class platform ecological embankment physical structural system is provided with a sedimentation and purification tank, a current restriction baffle and the like; and the slope ecological embankment physical structural system is provided with a bedding, iconological concrete, a plant growth pad and the like. The urban river multi-element ecological embankment physical structural system effectively integrates water treatment functions such as rainfall surface source collection and purification, discharge port sewage interception and purification, physical absorption and filtration and plant absorption and purification on the premise that the stability and safety of bank slopes are maintained, ecological environments and landscapes of urban riparian zones are improved, and the self cleaning capacity of rivers is well played.

Description

technical field [0001] The invention belongs to the technical field of revetment design and construction of landscape water bodies such as urban rivers and lakes, and specifically relates to a multi-elemental ecological revetment that has the function of collecting urban rainfall runoff non-point source polluted water bodies and has the function of intercepting and purifying water bodies of river bank slopes and sewage outlets physical structure system. Background technique [0002] While the economy has achieved rapid development, the pollution of rivers in some cities in my country has become increasingly serious, and unpleasant feelings such as stench have seriously affected the lives of surrounding residents. In order to improve the living environment of urban residents and the appearance of the city, many environmental protection departments and institutions across the country have proposed corresponding urban river water environment improvement plans, which generally i...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the shortcomings of the existing urban river channel vertical and slope combined revetment structures such as single function and weak ability to collect and treat exogenous water bodies, and construct a multi-elemental ecological bank revetment physical structure system, so that it can not only meet the function of river revetment, but also It also has the functions of collecting and purifying urban rainfall runoff non-point source polluted water bodies, intercepting and purifying water bodies at river bank slopes and sewage outlets, and restoring the riparian zone ecosystem
