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 present invention belongs to the design and construction technology field of landscape water body protection shores such as urban rivers, lakes, etc., which involves a diversified ecological protection shore that has a multi -ecological protection shore that has a collection function of the urban rainfall peculiar polluting water.Physical structure system. Background technique [0002] While the economy has achieved rapid development, some rivers in some cities in my country have become increasingly serious, and the unhappiness such as bad smell has a serious impact on 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 the corresponding urban river water environment improvement plan, which includes two aspects of rectification content: water quality improvement and river protection shor...

AI Technical Summary

Problems solved by technology

[0006] 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 external water bodies, and construct a multi-element 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
