Problems solved by technology

[0004] At present, the commonly used agglomerate is polyacrylamide. This kind of agglomerate is suitable for spraying greening on traditional high and steep slopes. It can achieve ideal greening effects when the slope is less than 60 degrees, and the slope is greater than 60 degrees. Especially When the slope is greater than 70 degrees, because the sprayed matrix is ​​difficult to resist the erosion of rainwater, the vegetation is difficult to grow, and due to the weight of the matrix, the matrix layer at the lower part of the slope is often thicker, the matrix layer at the top of the slope is thinner, and the vegetation covers the upper and lower sides of the slope. uneven

Abstract

The invention provides an agglomerate agent for spraying on high and steep slopes, which is composed of the following raw materials in parts by mass: 2-4 parts of modified polyacrylamide, 0.5-1 part of carrageenan, 0.5-0.8 parts of sodium alginate, Carboxymethyl starch 1~2 parts, ferric chloride 1~1.5 parts, calcium chloride 0.5~0.8 parts. The invention adopts the compounding method of organic and inorganic granulation agents, and modifies the organic granulation agent polyacrylamide, which improves its ability to granulate soil, and combines the characteristics of sodium alginate with calcium ion quick-setting, and compounded at the same time Carrageenan realizes the rapid formation of capillary aggregate structure of soil particles in the spraying matrix, making the matrix rapidly aggregated and avoiding the slipping of the matrix. It can be used for spraying slopes with a slope of more than 70 degrees. In addition, through the addition of carboxymethyl starch and ferric chloride The complex effect improves the long-term stability of the matrix aggregate structure, keeps the soil transparent, and resists rain erosion.

Description

technical field [0001] The invention relates to the technical field of slope restoration, in particular to a granule agent for spraying on high and steep slopes and an application method thereof. Background technique [0002] On the one hand, the mining of mineral resources provides the necessary resources for the society, on the other hand, it also causes damage to the ecological environment to varying degrees. The mine pits seriously damaged the original landform structure, resulting in land desertification, soil erosion, and greatly affected the natural ecology. . [0003] The traditional greening of high and steep slopes is mainly to spray soil with hanging nets, and spray the mud consisting of planting soil, fertilizers, water-retaining agents, adhesives, seeds, polymer aggregates, stabilizers, etc. to rocks or The guest soil layer is formed on the soil slope, and plants germinate and grow in it, forming vegetation covering the slope to achieve the greening effect. ...
