Nutrient medium for rock slope regreening and construction process thereof

Abstract

The invention discloses a nutrient medium for rock slope regreening and a construction process thereof. The construction process includes the steps of arranging a slope, distributing slope rainwater collecting and slow releasing devices, hanging a net on the slope, constructing anchor rods, spraying and spreading the nutrient medium, arranging a slope drainage system and performing later-period curing, wherein the nutrient medium to be sprayed and spread is mainly divided into three layers: the super-adhering nutrient medium, the super-bonding nutrient medium and the anti-scouring nutrient medium. By means of the construction process on the basis of a traditional process, the slope stability evaluation is increased; a rainwater collecting and slow releasing system is adopted for an improved mesh mode, and the curing time and curing cost are effectively reduced on the basis of ensuring the slope stability and good vegetable growth.

Description

technical field [0001] The invention relates to the field of ecological slopes, in particular to a nutrient matrix for regreening rock slopes and a construction process thereof. Background technique [0002] In the past, slope protection often pursued strength and efficacy too much, and most of them used simple engineering protection. These engineering measures not only destroyed the stability and aesthetics of the original natural environment, but also encountered exposed stone slopes, due to the stone slope Due to the lack of vegetation growth conditions, large slopes, and harsh natural conditions on the slope surface, simple engineering protection can no longer solve the problem of safety protection. Since the 1990s, my country has gradually changed from the use of simple concrete protection technology, such as mortar block stone, dry rubble, shotcrete, etc., to the use of vegetation reconstruction technology for slope ecological protection. That is, through the self-org...

AI Technical Summary

Problems solved by technology

[0003] But looking at the prior art, there are three prominent problems, 1, the maintenance time is long, need more than one year maintenance time; Once the maintenance is stopped, the vegetation degrades seriously

2. Most of the binders in the prior art are water-soluble compounds, which will be lost quickly under the action of curing and rainwater, and the bonding performance with the rock surface will be reduced

3. The anti-scouring ability is weak. It is necessary to sow a large amount of pioneer grass to fix the soil in the early stage, otherwise the "soil" sprayed on the rock surface will be lost quickly.
