Slope protection device and method

Abstract

The invention discloses a slope protection device and method. The slope protection device is laid on slopes of a naked mountain, a dike and the like and comprises protection base plates, non-woven fabrics and fastening nails. Each protection base plate is bent, forms an upward arc-shaped protrusion and is provided with a plurality of holes. The non-woven fabrics cover the surfaces of the protection base plates. The protection base plates covered with the non-woven fabrics are fixed to a slope through the fastening nails. A hollow space is formed in the face, making contact with the slope, of each protection base plate and is filled with fillers. The fillers are composed of a mixture of plant seeds, plant growth matrixes and fertilizers. The multiple protection base plates are laid adjacently and are integrally connected to cover the whole slope. According to the slope protection device and method, the protection base plates and grown plants are combined, slope water and soil erosion and rock weathering and corrosion can be prevented; and the slope protection device is simple in structure, low in cost, safe, environmentally friendly and good in protection effect.

Description

technical field [0001] The invention relates to a slope protection device and protection method, in particular to a protection device and a protection device for planting plants on a slope and preventing soil erosion of the slope and weathering and corrosion of rocks through the combination of the plants and the protection substrate. method. Background technique [0002] In recent years, with large-scale engineering construction and mining, a large number of exposed slopes have been formed on the mountain, resulting in a large number of rock and soil slopes that cannot recover vegetation. It is almost impossible to restore vegetation coverage naturally on the surface in a short period of time. Most of the reinforcement measures for slope engineering pursue strength and efficiency, and most of them use gray protection such as stone masonry and shotcrete, which destroys the harmony of natural ecology. [0003] As we all know, the traditional forms of slope protection for rive...

AI Technical Summary

Problems solved by technology

[0004] (1) Lack of ecology, it is not easy to plant grass and green on the slope, and destroy the original ecological environment of the river;

[0005] (2) Poor durability, poor adaptability to local deformation of the slope, and poor soil environment, prone to subsidence, embankment collapse, icing uplift, resulting in local damage or structural instability;

[0006] (3) Limited stone materials make the cost of traditional slope protection continuously increase;

[0007] (4) Once the rigid slope protection surface is partially damaged, it is prone to large-scale damage, the repair cost is high and the construction is inconvenient

[0008] Under the dams of rivers, lakes, etc. and on mountain slopes, large areas of water and soil erosion are often caused by rainwater erosion. Due to the special slope structure in these places, the soil matrix is ​​easily damaged by erosion when it rains heavily. After the heavy rain, it will quickly Drying is not conducive to the growth and retention of vegetation. In severe cases, it will cause debris flow disasters on the mountain and the breach of dams, which poses a great safety hazard
