Abstract

The invention discloses an adding soil spraying base material used for greening a rock steep slope. The base material is obtained by mixing and evenly stirring matrix soil, a solidifying agent, a soilreinforcement body and water, wherein the matrix soil includes red clay, ceramsite and humus soil, the solidifying agent includes cement, fly ash and gypsum, and the soil reinforcement body refers torice straw or wheat straw. The base material is light and can be rapidly solidified, and the problems are solved that a base material of adding soil of a steep slope is poor in stability and cannot be rapidly formed on the surface of the steep slope. Meanwhile, a porous soil structure is conducive to water and fertilizer conservation and the development of a plant root system, and the survival rate of vegetation is ensured. Local materials can be easily obtained and are convenient to use, construction is simple, the technical treatment cost is low, and the base materials have huge economic benefits.

Description

technical field [0001] The invention relates to a guest soil spraying base material for greening steep slopes of rocks, in particular to a guest soil spraying base material suitable for steep slope greening in Southwest China, which belongs to mine restoration, municipal and road slope engineering regreening technology field. Background technique [0002] Most of the southwestern regions of my country are steep mountains, and it is inevitable to carry out excavation and filling construction during production and construction, involving many fields such as mines, water conservancy, electric power, municipal engineering, and roads. If the exposed bedrock surface after excavation is not treated, it will easily lead to water and soil erosion, which will lead to ecological damage and affect the regional environment. It is very effective to use spraying equipment to spray foreign soil on the exposed rock and soil surface to realize the regreening of the mountain. [0003] Most o...
