Embodiment 1
[0050] Example 1 Ecological Softening of Hard Embankment Slope Protection
[0051]Before construction, clean up the construction site, manually or mechanically eradicate the weeds in the construction site, protect the accumulated water in the construction site, mechanically excavate trenches, carry out natural drainage to low-lying rivers, and transport the cleared topsoil to the roadbed The external spoil ground shall not affect the smooth flow of the road. Existing houses, roads, ditches, communications, power facilities, water and sewage, tombs and other buildings within the scope of construction shall be demolished or rebuilt in advance with the assistance of relevant departments; Dangerous buildings nearby should be appropriately reinforced; cultural relics and historic sites should be properly protected.
[0052] Then follow the steps below for construction:
[0053] (1) Outside the original slope protection, backfill the block layer and the plain soil layer for plant g...

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...
