Riverbank vegetation buffer zone planting structure with embankment strengthening and bank protection performance

Abstract

The invention discloses a riverbank vegetation buffer zone planting structure with embankment strengthening and bank protection performance. The riverbank vegetation buffer zone planting structure relates to the technical field of riverbank vegetation planting, and comprises a buffer zone located on an upslope of a riverbank. According to the riverbank vegetation buffer zone planting structure with the embankment strengthening and bank protection performance, water flow flows through a drainage channel, and when the water flow passes through a filter screen, pollutants are filtered; and when the pollutants are cleaned, an annular plate firstly sleeves a communicating pipe, an annular rod and the filter screen are moved to enable the pollutants to enter a collecting net, then the annular rod and the filter screen are moved reversely, the water flow completely passes through the filter screen again, after the pollutants completely enter the collecting net, the collecting net is taken out, the pollutants in the collecting net are cleaned, it can be guaranteed that the pollutants can be completely cleaned when the pollutants are cleaned, pollution cannot be caused, and the problem thatwhen a filtering device in an existing riverbank vegetation buffer zone structure cleans the pollutants, a small number of pollutants are prone to passing through a drainage channel to cause pollution is solved.

Description

technical field [0001] The invention relates to the technical field of river bank vegetation planting, in particular to a buffer zone planting structure of river bank vegetation with the performance of embankment reinforcement and revetment. Background technique [0002] The vegetation buffer zone is a vegetation area with a gentle slope, which uses vegetation interception and soil infiltration to slow down the surface runoff velocity and remove some pollutants in the runoff. The slope of the vegetation buffer zone is generally 2%-6%, and the width should not be less than 2m. The vegetation buffer zone has the functions of intercepting rainwater, preventing rainwater splash erosion, reducing surface runoff, preventing surface water erosion, preventing trampling, increasing water infiltration, and fixing soil by roots and supporting functions; purify water quality, reduce non-point source pollution; improve biological habitat functions; increase landscape diversity and other ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a planting structure of a river bank vegetation buffer zone with the performance of embankment reinforcement and revetment, which solves the problem that a small amount of pollutants can easily pass through the filter device in the existing river bank vegetation buffer zone structure when cleaning pollutants. Drainage canals cause pollution and the structure of the existing river bank vegetation buffer zone is relatively simple. Generally, plants are directly planted on the river bank, and the use effect is very poor.
