Technical Field

The invention belongs to the field of vegetation restoration and treatment, and particularly relates to a vegetation restoration process for a high and steep slope.

Background

At present, in order to meet the environmental protection requirement of sustainable development, vegetation damaged in the construction process of a wind power plant is required to be recovered frequently, and natural recovery and foreign soil spray seeding are adopted for recovering the vegetation in the high-mountain wind power plant.

Natural restoration is suitable for soil slopes, but vegetation restoration speed is low, and the vegetation restoration can be realized in three or four years, and the natural restoration is not suitable for rock slopes; the method mainly adopts a mesh anchoring mode, can be used for soil slopes and rock slopes, and can quickly recover the vegetation, but is not suitable for high slopes and rock slopes with the slope larger than 60 degrees, and the soil adheres unstably to a stone wall due to the steep slope, so that the soil dressing falls off.

Disclosure of Invention

Based on the background problem, the invention aims to provide a preparation and recovery process of a high and steep side slope, plant straws and a fixed inserting piece structure are added in a net piece, and the adhesive force is enhanced, so that the defect of unstable adhesion of soil and a stone wall in the prior art is overcome, and the preparation and recovery process can be used for the high and steep side slope; it is another object of the present invention to provide a structure formed by the above vegetation restoration process for a high and steep slope.

A vegetation recovery process for a high and steep slope is characterized in that a plant straw layer is laid on a ribbed mesh arranged on the surface of a slope body, and fixing inserting pieces are inserted into meshes of the ribbed mesh at intervals to increase the adhesive force of foreign soil.

Wherein, spray slurry on the plant straw layer in order to make the rock wall moist, spray growth substrate and plant seed in proper order, cover the non-woven fabrics at last and preserve soil moisture.

In order to achieve the above object, the present invention also provides a vegetation restoration structure for a steep side slope, comprising: the reinforced net sheets are arranged on the surface of the slope body and are fixed; the plant straw layer is formed by winding plant straws on the ribbed net sheet and fully spreading the ribbed net sheet; and the fixed inserting pieces are inserted into the meshes of the reinforced net sheet at intervals.
