A greening device and method for high and steep rock slopes based on cement blankets

Abstract

The invention provides a greening device and method for high and steep rock slopes based on cement blankets. The device comprises a plurality of cement blanket planting troughs with upward openings; the cement blanket planting trough is fixed on a rocky slope, and a self-adjusting planting layer structure is arranged inside the cement blanket planting trough. The structure of the self-adjusting vegetation layer is a structure in which the gauze layer, the coarse sand layer, the lower planting soil layer, the water storage board layer, the geotextile layer, the upper planting soil layer and the ceramsite layer are laid horizontally from bottom to top. A water transport channel is vertically arranged inside the vegetation layer structure. The device has the advantages of low cost, stable structure and strong landscape plasticity. The greening method provided by the invention has the advantages of simple operation and low 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 rock slopes based on cement blankets. Background technique [0002] High and steep rocky slopes are a kind of extreme habitats, due to their steep slope (≥45°), high slope (≥20m), unstable slope mechanical properties, large temperature difference between day and night, and the same slope. The slope aspect and slope shape are not the same. There is no soil moisture on the slope, and it is difficult for plants to grow. Therefore, the ecological restoration of high and steep rock slopes is one of the focus issues of many scholars. [0003] The existing common methods for ecological restoration of high and steep rock slopes include: hanging net spraying technology, ecological bag greening technology and V-shaped planting trough greening technology, etc., but there are also the following shortcomings: 1. Spray seedin...

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.
