A kind of slope ecological restoration method

Abstract

The invention provides an ecological restoration method of a slope. The ecological restoration method of the slope comprises the steps of smoothing the slope surface, paving geotechnical cloth on the smoothed slope surface and fixing the geotechnical cloth by use of an anchor rod, paving a honeycomb restraint system on the geotechnical cloth and fixing the honeycomb restraint system by use of an anchor rod, filling a plant growth substrate, paving a lawn nursery strip on the honeycomb restraint system, and nursing plants after paving is completed, wherein the honeycomb restraint system is composed of cells and reinforced belts passing through the cells; the lawn nursery strip comprises a geonet, setting paper, grass seeds, a slow release fertilizer and the setting paper, all of which are orderly paved from top to bottom; the ecological restoration method of the slope has the advantages that as the honeycomb restraint system is paved on the slope, the service life of the work can be greatly increased, the maintenance cost is reduced and the construction period is shortened, and the honeycomb restraint system is good in water permeability and moisture retention property, and capable of protecting soil from erosion by rainwater, and conserving and retaining soil; the method is short in construction period, convenient for maintenance, low in cost, capable of reinforcing the slope while restoring the ecology of the slope, and suitable for the soft foundation slopes of various gradients.

Description

technical field [0001] The invention relates to a slope ecological restoration method, in particular to a joint construction method of a honeycomb restraint system and a vegetation belt, and belongs to the technical field of ecological restoration. Background technique [0002] The structural stability and ecological restoration of slopes are involved in the construction of high-speed railways, expressways and river management. These slopes are an important part of high-speed railways, highways and rivers. If they are not handled properly, they will fall, collapse, slide and even landslide, which will seriously affect the beauty of the environment, lead to soil erosion, and even cause traffic interruption, river silting, and accidents. Cause huge economic losses and personal safety. [0003] Slope stabilization and ecological restoration have become an important part of road, railway, and river slope management. How to adapt measures to local conditions and slopes according...

Problems solved by technology

[0004] At present, the commonly used methods for slope stabilization and ecological restoration are ecological concrete, mortar masonry or dry stone blocks, cast-in-place concrete, prefabricated concrete blocks, gabion nets, ecological bags, ecological blankets, guest soil spraying and other methods. The slope protection method or engineering cost is high or the construction and maintenance work is difficult, and some methods only start from the stability of the slope and the safety of the flood discharge of the river, without considering the impact on the environment and ecology, and few can combine safety and stability with the ecology. The method of perfect combination of benefits, for slopes with a slope ≥ 60°, due to the large slope, landslides and even landslides are prone to occur, making the ecological restoration of steep slopes more difficult
