A kind of vegetation concrete and preparation method thereof

Abstract

The invention discloses a vegetation concrete, comprising the following components in parts by weight: 50-100 parts of soil, 10-50 parts of organic nutrient soil, 1-10 parts of cement, 1-10 parts of gypsum, and 0.1-5 parts of organic binder parts, 1-10 parts of plant fibers, 0.1-5 parts of water retention agent, 3-7 parts of plant growth regulators, 0.1-1 parts of attapulgite, 0.05-0.5 parts of plant seeds, and 30-90 parts of water. It has strong adhesion and erosion resistance, is rich in nutrients, and is loose and porous, which can restore the ecological environment and create a plant landscape, which is conducive to the long-term and stable growth of vegetation concrete, and has excellent frost resistance and cold resistance, suitable for cold areas and Vegetation concrete works construction in autumn and winter. The invention also discloses a preparation method of the above-mentioned vegetation concrete. The preparation method is easy to operate, and the preparation conditions are easy to control. The prepared vegetation concrete is suitable for plant growth and beneficial to the restoration of ecological environment.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a vegetation concrete and a preparation method thereof. Background technique [0002] In recent years, in the construction of water conservancy, electric power, highway, railway and other infrastructure projects, a large number of slopes are often excavated. The development of the slope has destroyed the original vegetation cover, resulting in a large number of rocks and land being exposed, resulting in a series of ecological environment imbalance problems, such as soil erosion, landslides, debris flows, deterioration of local microclimates and destruction of biological chains, etc. . The exposed slopes caused by these projects often take a long time to restore the ecological balance if only relying on the forces of nature. Soil slopes can achieve ecological restoration in a relatively short time through artificial protection and greening, but it is difficult for...

AI Technical Summary

Problems solved by technology

[0005] (1) Ordinary concrete is used as the base material for spraying. When the amount of cement is small, the bonding ability and anti-scouring ability of vegetation concrete are weak, and the effect of slope protection cannot be achieved; when the amount of cement is large, the alkalinity of concrete Stronger, resulting in poor soil structure, easy to harden, and there is no environment suitable for plant growth such as air and water in the spray substrate, and it is also not conducive to the degradation of organic matter and the formation of a micro-environment for microorganisms, resulting in low germination and survival rates of vegetation seeds. Using plants to restore ecology;

[0006] (2) Using pure soil as the spray base material is suitable for plant growth, but the firmness between the spray base material and the slope is limited to a certain extent, and the strength and durability of the vegetation concrete layer cannot meet the requirements

[0007] (3) Many vegetation concrete greening projects have good ecological restoration effect in the first one or two years, and then the problems of vegetation death and soil loss begin to appear, and the long-term stability and sustainable development of vegetation concrete have not been realized.

[0008] (4) The existing vegetation concrete has poor frost resistance and cold resistance, and basically cannot be used normally in cold regions and autumn and winter when the temperature is low
