Method for ecologically softening hard revetments

Abstract

The invention particularly relates to a method for ecologically softening hard revetments, including hardened revetments and unhardened revetments which need ecological restoration. According to the method, on the premise that the structure of an original revetment is not damaged, the unit layers of the original revetment are backfilled with lumps and plain soil one by one from the lowest one, tamping is carried out, and stiffening nets and stiffening ribs are laid on the unit layers; seepage water pipes can also be laid on the unit layers in a pre-buried mode. When backfilling is carried out on the highest layer of the original revetment, the highest layer can be backfilled with sandy soil instead of lumps and plain soil so that a sandy soil layer can be formed. After backfilling is finished, a layer of air-permeable and water-permeable geotextile is laid on the slope of a plain soil layer, then, gabions are installed layer by layer along the slope from the bottommost part, the gabions can be installed at a time when construction conditions allow, and adaptable plants are fixedly planted in the gaps between the gabions or in the gabions. According to the method, hardened revetments can be ecologically softened, and the unhardened revetments which need restoration can be restored; the revetments can be more stable, and construction waste, building material waste and living and production waste residues can be recycled after being effectively treated.

Description

technical field

[0001] The invention relates to the technical field of slope protection ecological comprehensive management, in particular to a method for ecological softening of hard slope protection (including hardened slope protection and unhardened slope protection requiring ecological restoration). Background technique

[0002] According to the "China's Ecological Restoration Industry Market Prospect and Investment Strategic Planning Analysis Report Prospect", the deterioration of the ecological environment is manifested in the destruction of vegetation, soil erosion, desertification and other aspects. According to the second national land erosion remote sensing survey, the area of ​​soil erosion in my country is 3.56 million square kilometers, and the desertified land is 1.74 million square kilometers. 1.349 million hectares, 2.383 million hectares of land occupied or destroyed by mining activities, with serious vegetation damage. In recent years, the adverse effects o...
