Problems solved by technology

However, there are the following problems: on the one hand, this kind of protective surface cannot grow plants, cannot restore regional ecology, and has poor visual senses; on the other hand, the cost of protective materials and construction is high, and the durability of the materials used is poor. In the later period, the slope surface will be weathered, the strength will be reduced, and the situation will be damaged again. The protection life is not long and the maintenance cost is high.
The raw material components used in the existing guest soil spraying substrate mixture are varied, and there are many problems, such as: some use peat soil (or peat soil) as organic matter, although it can provide rich nutrients needed for plant growth, but peat soil It is a precious natural resource that is difficult to regenerate, and it needs to be transported long-distance from the place of origin to the construction site. The cost is high and it is not suitable for large-scale use; some use a large amount of fly ash, slag or iron tailings as admixtures, although It can consume solid waste from some industrial and mining enterprises, but these inorganic solid waste are difficult to be used by plants for slope protection, and will also increase the pH value of the base material mixture, resulting in burning seedlings and soil deterioration; Use cement or high molecular polymer as the binder to change the pH value and physical and chemical properties of the base material mixture. It is necessary to add additional pH regulators, soil improvers, aggregate agents, etc., and many chemical substances are used, which cannot be destroyed in nature. Decomposition will increase the environmental burden in the residual soil, and the cost is high, and the long-term ecological protection effect is average, so it is not suitable for large-scale promotion and use

Abstract

The invention relates to a road slope ecological protection soil spraying base material mixture and a preparation method thereof. According to the road slope ecological protection soil spraying base material mixture, a bottom base material mixture is composed of water, planting soil, steam exploded stalk fiber, crushed raw stalk, decomposed microbial bran and compound fertilizer, a surface base material mixture is composed of water, plant seeds, planting soil, steam exploded stalk fiber, decomposed microbial bran and compound fertilizer, wherein the steam exploded stalk fiber is prepared by cutting off and soaking dried wheat stalk in water and then performing dewatering extrusion and steam explosion. The road slope ecological protection soil spraying base material mixture is obtained fromlocal materials and fully recycles and utilizes agricultural waste, thereby being low in cost; biomass-based adhesive materials produced by the steam exploded stalk fiber help save cement and other chemical adhesives; the decomposed microbial bran can serve as biological organic fertilizer for synergizing with the stalk fiber to save additional chemical agents such as water-retaining agent and soil conditioning agent. The road slope ecological protection soil spraying base material mixture can promote slope plant turf covering within a relatively short time to restore slope ecosystem, avoid water and soil loss and achieve good slope ecological protecting effects.

Description

technical field [0001] The invention belongs to the technical field of road slope ecological protection, and in particular relates to a soil spraying base material mixture for road slope ecological protection, and also relates to a preparation method of the soil spraying base material mixture. Background technique [0002] With the rapid development of my country's economy, the demand for passenger and cargo transportation has increased sharply. In order to alleviate the transportation pressure and promote regional exchanges and integration construction, the construction of road and railway networks has been accelerated, and more and more hills and mountains have been penetrated. When building roads and railways in mountainous and hilly areas, it is necessary to excavate rock and soil, resulting in a large number of exposed slopes, which not only destroys the original landform, blocks the continuity of regional hydrology, and affects the local ecosystem, but also easily Caus...
