Gully ecological slope protection structure and construction method thereof

Abstract

The invention discloses a gully ecological slope protection structure and a construction method thereof. The slope protection structure comprises first protection components laid on the slope surface of a gully, second protection components laid on the sloe toe, and third protection components laid at the bottom of the gully. At the junction of the slope surface and the slope toe, the first protection components and the second protection components are laid in an embedding manner. Main body edges of every two adjacent first protection components are in close contact, and a groove structure is formed between two upper bosses of the first protection components. The slope surface protection components, the slope toe protection components and the protection components in the gully bottom direction are arranged, and therefore the problems that in measures in the prior art, the slope protection stability is poor, water permeability is poor, the construction is complex, cost is high, and the vegetation recovery effect is poor are solved.

Description

technical field [0001] The invention relates to the technical field of ecological slope protection, in particular to an ecological slope protection structure and a construction method for large and medium-sized cutting ditches in the black soil region of Northeast China. Background technique [0002] The gully is a downcut channel formed by the concentrated erosion of surface runoff during the rainstorm or meltwater period. Its depth is more than several meters. According to survey statistics, the width of the gully in the black soil area of ​​Northeast China ranges from a few meters to tens of meters, the length of the ditch ranges from a dozen meters to hundreds of meters, some can reach hundreds of meters, and the depth of the ditch ranges from tens of centimeters to several meters. There are 296,000 erosion ditches, of which nearly 90,000 are more than 1,000 meters long. Cutting trenches increases soil erosion, can easily cause storm and flood disasters, have a destruct...

AI Technical Summary

Problems solved by technology

[0005] Based on the above problems, the present invention provides a ditch-cut ecological slope protection structure and its construction method. By laying slope protection components, slope toe protection components and protection components along the direction of the ditch bottom, the existing technical measures for slope protection have poor stability and water permeability. Poor performance, complex construction and high cost, poor vegetation restoration effect, etc.
