Spray sowing ecological restoration method for stone side slope of highway

Abstract

The invention discloses a spray sowing ecological restoration method for a stone side slope of a highway, comprising the following restoration steps of: trimming a side slope; hanging a mesh; carrying out primary mixed spraying; carrying out secondary mixed spraying; covering; and maintaining. According to the method, the most space of a rock stratum is filled with the prepared mixed matrix and the shrub grassroots due to the primary mixed spraying, so that the matrix and grass shrub adhering space can be increased for the secondary mixed spraying, the rock stratum can be further stabilized and the vegetation growing space can be increased; by adjusting the proportion of the binder in the mixed matrix, the lubrication action can be played in the mixed pulp, the caking of fiber can be avoided, thereby facilitating the mixed spraying operation and enhancing the adhesive force between the fiber and the soil after spray sowing; and the thickness of the adhesion matrix can be effectively increased due to the secondary mixed spraying, so that the grass shrub vegetation can be planted within the reasonable space of the matrix. According to the two-time mixed spraying technology of the method, the soil erosion and the slope surface collapse can be furthest avoided, the ecological community with biodiversity can be built, and the greening effect and the ecological benefit can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, in particular to an ecological restoration method for rocky slopes of highways by spraying mixed vegetation. technical background [0002] With the promotion and application of slope plant protection technology, various slope plant protection technologies have developed into an important part of the construction of road and railway green passages, but there are still some problems.

The application number is 02115391.4, and the invention patent titled "A kind of raw material for sprayed and mixed planting on rock slope and its preparation and construction method" discloses a raw material for sprayed and mixed planting on rocky slope and its preparation and construction method. Slope spray mixed planting raw material is a composition, which is prepared by uniformly mixing soil, organic matter, compound fertilizer, water retaining agent, cement, pH regulator, plant seeds and water at room temperature. Although it has a certain effect of maintaining water and soil, However, the adhesion of the matrix is ​​still lacking when spraying, and its ecological restoration effect still needs to be improved.
