Problems solved by technology

Traditional soil stabilizers (curing agents) can directly cement the surface of soil particles or react with clay minerals to form gelled substances, thereby increasing the viscosity of the sprayed matrix, increasing the strength and stability of the matrix, and forming effective water resistance. It is beneficial to solve the problem of instability or shedding of the soil layer after spraying, but too much dosage will make the soil easy to harden, which will affect the growth of plants

Abstract

The invention relates to a soil structure stabilizer and a preparation method thereof, and belongs to the technical field of soil conditioning. The soil structure stabilizer comprises the following components in percentage by weight: 30%-50% of an adhesive, 30%-50% of a curing agent and 5%-30% of an ion exchanger. The soil structure stabilizer provided by the invention can change the soil structure of an earth-rock slope, improves the properties of soil mechanical strength, water stability, scouring resistance, wind erosion resistance and the like, and has little influence on the growth of vegetation.

Description

technical field [0001] The invention relates to a soil structure stabilizer and a preparation method thereof, belonging to the technical field of soil conditioning. Background technique [0002] The foreign soil spraying technology is a slope regreening technology that has emerged in recent years. The spraying machine sprays various substrates and plant seeds onto the slope to form a vegetation layer, which can effectively protect the stability of the slope. So as to achieve the purpose of quickly rebuilding the vegetation ecosystem and biological slope protection. However, the alien soil spraying technology has high requirements on the slope slope. For slopes with a slope greater than 45°, the alien soil layer will fall off seriously after construction, and it is difficult to exist stably on the slope surface for a long time. In order to make the spraying matrix stick well on the slope, soil stabilizers (curing agents) have been widely used as soil stabilizing materials in...
