High and steep rock slope greening device and method based on cement blanket

Abstract

The invention provides a high and steep rock slope greening device and method based on a cement blanket. The device comprises a plurality of cement blanket planting grooves with upward openings; the cement blanket planting groove is fixed to the rock slope, and a self-adjusting vegetation layer structure is arranged in the cement blanket planting groove. The self-adjusting vegetation layer structure is a structure formed by horizontally laying a gauze layer, a coarse sand layer, a lower planting soil layer, a water storage plate layer, a geotechnical cloth layer, an upper planting soil layer and a ceramsite layer in sequence from bottom to top; and a water conveying channel is vertically arranged in the self-adjusting vegetation layer structure. The device has the advantages of being low in manufacturing cost, stable in structure and high in landscape plasticity. The greening method has the advantages of being easy to operate and low in engineering cost.

Description

technical field [0001] The invention relates to the technical field of slope ecological restoration, in particular to a greening device and method for high and steep rocky slopes based on cement blankets. Background technique [0002] High and steep rocky slopes are a type of extreme habitat, due to their steep slope (≥45°), high slope (≥20m), unstable mechanical properties of the slope surface, large diurnal temperature variation of the slope surface, and the same side Slope aspects and slope shapes are not the same, and there is no soil moisture on the slope surface, making it difficult for plants to grow. Therefore, the ecological restoration of high and steep rocky slopes is one of the focus issues studied by many scholars. [0003] The existing common methods for ecological restoration of high and steep rocky slopes include: hanging net spraying technology, ecological bag greening technology and V-shaped planting groove greening technology, etc., but there are also the ...

AI Technical Summary

Problems solved by technology

[0003] The existing common methods for ecological restoration of high and steep rocky slopes include: hanging net spraying technology, ecological bag greening technology and V-shaped planting groove greening technology, etc., but there are also the following deficiencies: 1. Spraying in the spraying technology The base material is thin, the water retention performance is poor, the long-term stability of the base material is insufficient, the water and soil loss is serious during the rainfall period, the vegetation survival rate is low, and the practical value is relatively low; The high scaffolding platform has complex construction procedures, great safety hazards, long construction period, and high cost; 3. The high and steep slopes require a lot of cleaning due to the changeable slope direction, slope change, and micro-topography of the slope surface. In order to create a construction work surface, the existing technology has problems such as poor terrain adaptability and small space for landscape plasticity.
