The appearance of the surface layer is uneven, and the material is loose and flexible, leaving more than % space that can be filled with soil and sand. Function: Before the turf is formed, when the slope angle is degrees, the soil-fixing blocking rate of the three-dimensional vegetation mesh mat is as high as .%. When the slope angle is degrees, the blocking rate is also as high as %. Even when the slope angle is vertical, The hysteresis rate can still be as high as %. Using polymer materials and carbon black additives, its chemical stability is reliable and its underground life span can be up to 20 years. It can play the role of this composite mechanical interlocking system throughout the design life of transportation and water conservancy projects. Three-dimensional soil-fixing mesh pad Three-dimensional vegetation mesh plastic mesh Three-dimensional vegetation soil-fixing mesh pad is composed of multi-layer plastic concave-convex mesh and two-way stretched plane mesh, which are bonded after hot melting at the intersection points to form a stable three-dimensional mesh structure. The appearance of the surface layer is uneven, and the material is loose and flexible, leaving more than % space that can be filled with soil and sand. The bottom two-way stretch mesh has the characteristics of low elongation and high strength, which plays a role in preventing the slope from sliding down. The roots of plants can pass through the entire vegetation mesh comfortably and evenly deep into the ground up to .-meter deep. In this way, the vegetation, mesh and soil form a strong composite mechanical interlocking system to achieve the purpose of protecting the slope. .
The soil-fixing effect is very obvious. Tests have shown that before the turf is formed, when the slope angle is degrees, the soil-fixing blocking rate of the three-dimensional vegetation mesh mat is as high as . The retardation rate can still be as high as %. That is to say, on vertical slopes where soil should not or cannot be retained, % of the soil can still be retained due to the presence of the mesh mat. Therefore, the three-dimensional vegetation mesh mat has an excellent soil-fixing effect that is far better than the flat mesh. .
. It can protect the slope from wind and rain erosion before the turf grows.
After the grass seeds are sown, the grass seeds can be firmly kept evenly distributed on the slope and protected from being lost by wind and rain.
After the turf is grown, it forms a strong composite mechanical interlocking system with the mesh mat and soil, which can prevent the impact of heavy rain and strong winds, and can withstand the impact of high water levels and large flows, replacing concrete and mortar rubble. etc. as a permanent slope protection layer.
The use of black mesh mats is beneficial to absorbing a large amount of heat energy, increasing ground temperature, promoting seed germination and extending the plant growth period.
Due to the rough and uneven surface, wind and water flow generate countless small eddies on the surface of the mesh pad, which can dissipate energy and promote the deposition of carried objects in the mesh pad.
, using polymer materials and carbon black additives, its chemical stability is reliable and its underground life can be as long as 20 years. It can play the role of this composite mechanical interlocking system throughout the design life of transportation and water conservancy projects (if there are special needs Biodegradable plastic mesh mats can be used that will disappear in the soil after a few years without leaving traces).
Green vegetation can absorb motor vehicle exhaust and can beautify the landscape, protect the environment and green roads and railways.

Three-dimensional network spraying and regreening
1. Introduction
The three-dimensional network spraying and regreening process is a matrix containing plant seeds, adhesives, fertilizers, water-retaining agents, reinforcing fibers, etc. A slope greening method in which viscous mud prepared with water is directly sprayed onto a slope covered with a three-dimensional mesh (filled with organic matter-rich mud or covered with loose organic matter soil).
2. Basic Principles
Three-dimensional vegetation nets are mostly made of polyethylene and polypropylene materials, and are made of high-polymer films through regular punctures, heating, and stretching. The bottom layer of the three-dimensional vegetation net is a high-modulus base layer (biaxially stretched flat net), and its higher-strength surface layer is a multi-layer plastic convex-concave net. The surface layer and the bottom layer are bonded through hot melt points at the intersection points to form a stable three-dimensional network structure. . It is non-corrosive and chemically stable.
The texture of the three-dimensional vegetation net is loose and soft, leaving % space that can be filled with soil. Before the vegetation becomes a flat surface, it can effectively prevent soil erosion and protect the slope from wind, rain and flood erosion. After the grass seeds are planted, it can firmly protect it. Grass seeds are evenly distributed on the slope, allowing the roots of the plants to pass through the convex and concave net bags to grow comfortably, neatly and evenly, and better combined with the slope soil. The surviving turf can make the three-dimensional vegetation net and the turf and all The attached soil forms a strong interlocking system to effectively prevent water and soil erosion, protect the roadbed, form a green composite protective layer on the slope, and at the same time achieve the purpose of improving the ecological environment of the road area.
The three-dimensional vegetation network strengthens the shallow protection of slopes in the following ways: First, within a certain slope thickness range, it prevents the soil on the slope surface from being directly eroded by rainwater and sediment flow through its own dense coverage. The energy during scouring reduces the surface runoff velocity, thereby reducing the loss rate of soil particles. Secondly, due to the existence of the three-dimensional vegetation network, the huge root system of grass and shrubs is connected with the mesh of the three-dimensional network to form a plate structure, thereby increasing the resistance of the protective layer. Tensile strength and shear strength limit the expansion of the gradual failure phenomenon caused by erosion and ultimately limit the occurrence of shallow sliding and uplift on the slope surface. The third is to improve the slope soil structure through the growth of plants and gradually increase the erosion resistance of the slope soil.
The test shows that the three-dimensional vegetation net slope protection technology combines the advantages of geonet and plant slope protection and plays the role of composite slope protection. When the vegetation coverage rate of the slope reaches more than %, it can withstand the erosion of light rain. When the vegetation coverage rate reaches more than %, it can withstand the erosion of heavy rain. At the same time, the three-dimensional vegetation network has a good effect on reducing the evaporation of water in the slope soil and increasing the infiltration amount.
