Side slope protection and vegetation restoration method

Abstract

The invention provides a side slope protection and vegetation restoration method. A two-layer fiber structure, namely a bottom layer and a surface layer, is adopted, the bottom layer comprises heat treatment wood fibers and a biological adhesive; and the surface layer comprises heat treatment wood fibers and man-made interlocking fibers. The thickness ratio of the bottom layer to the surface layeris 1:1-2. The thickness of the bottom layer is 3-4mm; the thickness of the surface layer is 4-6mm. By the adoption of the method, after construction is conducted for two hours, a slope surface can resist scouring of heavy rain from middle rain to heavy rain. By means of the method, the slope can be effectively protected, and vegetation restoration is guaranteed.

Description

technical field [0001] The invention relates to a slope protection method, and relates to a steep slope protection and vegetation restoration method in a soil environment where plants are difficult to grow and rainy areas, and specifically relates to a soil environment such as a slag storage yard, a crushed stone storage yard, and a soil borrowing site for road construction, which are frequently subjected to heavy rain. The scoured slope protection and vegetation restoration method, especially the slope protection in remote areas with harsh natural conditions, belongs to the technical field of environmental protection. Background technique [0002] Early slope protection methods generally include the following methods: one method is to directly sow plant seeds on the slope. This method is generally suitable for slope protection with relatively gentle slopes, relatively good soil conditions, and relatively good natural conditions. Another method is to cover the slope with a ...

AI Technical Summary

Problems solved by technology

But, the use environment of above-mentioned technology is still limited, it is still difficult to overcome the protection of the harsh environment and barren soil condition slope applied by the technical solution of the present invention

The following problems cannot be solved: lack of soil in remote areas, high transportation costs; extremely poor slope conditions, including a large amount of gravel, etc., the cost of transforming the original soil layer is too high; Retention, water and soil loss is relatively large; the cost of the large thickness of the soil improvement layer is relatively large, and the soil improvement layer is very easy to be washed out during the construction process. Frequent washing during the plant growth period after construction is difficult to ensure the growth of the root system of the plant seeds and the overall The problem of low coverage and survival rate of

[0010] The soil improvement layer of the method in the prior art needs to be constructed for a long time before it has a certain anti-scouring ability. During this period, heavy rainfall will wash away most of the seeds, guest soil, etc.; from seeds to growing plants, and then to It takes a long time to grow to form a certain scale; during this period, the seeds left on the slope are subjected to frequent rainfall erosion, and the root system of the plant grows slowly, making it difficult to take root and grow on the slope with poor soil quality, and it is even more difficult to form a vegetation scale , the coverage of vegetation is difficult to meet the needs of slope protection; with the existing technology, due to the poor soil quality of the slope, the porosity, moisture content, and nutrient components are all seriously low, and the plant roots cannot take root and grow. Therefore, the plant roots only It can grow in the improved guest soil layer; the improved soil and the original soil of the slope cannot be integrated into one, forming a "two-layer skin" phenomenon, and the two cannot be integrated; it cannot maintain the protection of the slope for a long time

To sum up, the existing technology cannot fundamentally solve the problem of slope improvement and greening with severe degradation such as slag storage yards, gravel storage yards, and borrow pits for road construction in remote and rainy areas.
