Filling device and method for ecological slope protection

Abstract

The invention relates to a filling device and method for ecological slope protection. The filling device comprises a supporting rod, a protective net and geotechnical cloth, wherein one end of the supporting rod is a fastening end used for being fixed to a slope surface, and the other end of the supporting rod is a connecting end; the connecting end is sequentially connected with the protective net and the geotechnical cloth in the direction close to the slope surface; an elastic rope is jointly connected between the geotechnical cloth and the protective net; the supporting rod is further provided with a staged opening assembly; and the staged opening assembly is used for driving the geotechnical cloth to move in a staged mode in the direction close to the slope surface. According to the filling device and method for ecological slope protection, by arranging the geotechnical cloth and the staged opening assembly capable of changing the distance between the geotechnical cloth and the protective net, a first spray-seeding covering layer and a second spray-seeding covering layer can be well attached and stabilized, the sunken position of the slope surface is filled, and water and soil loss of the spray-seeding covering layers at the sunken position is reduced, so that the vegetation slope protection function of ecological slope protection is ensured.

Description

technical field [0001] The present application relates to the field of construction devices for ecological slope protection, in particular to a filling device and method for ecological slope protection. Background technique [0002] Large-scale infrastructure projects such as highways often carry out a large number of filling, excavation and mountain cutting works on the occupied area according to the requirements of alignment, elevation and space, thus forming different types of exposed slopes, which make the original vegetation It has completely disappeared and caused serious damage to the surrounding ecological environment. Therefore, it is necessary to rebuild the soil and restore the vegetation on the bare slope through manual intervention, that is, to build an ecological slope protection. [0003] At present, the vegetation restoration project on slopes, especially high and steep slopes, mainly adopts the hanging net spraying technology, which is to mix planting soil, ...

AI Technical Summary

Problems solved by technology

[0004] Regarding the related technologies mentioned above, the inventor believes that this general technology is only effective when the slope quality is moderate and the slope surface is flat, but when the slope site conditions are hard rock slopes and there are many rough and uneven slopes In the case of local micro-topography with vertical and horizontal ravines and variable slopes, it is difficult for the metal mesh hanging on the slope to cover the slope closely, so that the spraying matrix is ​​seriously lost due to the suspension of the metal mesh, and it cannot form a firm attachment on the slope. The vegetation spray layer will become the intrusion site of water and soil loss and damage the overall vegetation slope protection function.
