Geomat is one triplanar netting structure used for soil fixing and grass planting. The structure leaves 90% of space to be filled with soil, gravel and small stones, help plant roots go through it, the soil surface and plant could be firmly bound together. Usually the plant roots can reach as deep as 30-40cm below the surface, so the binding forms a solid green composite protective layer, this layer can withstand high-level, high-velocity water erosion.
Geotechnical mesh mat slope protection technology can effectively solve the protection problems of rock slope and high and steep slope by combining the advantages of geotechnical mesh and vegetation slope protection. The application example shows that the slope protection of three-dimensional vegetation net is very beneficial to the stability of slope, and the protection effect is very good.
Geotechnical mat slope protection is a new technology that uses active plants and engineering materials such as geosynthetic materials to build a protection system with its own growth ability on the slope and strengthen the slope through the growth of plants. According to the characteristics of slope topography, soil quality and regional climate, the slope surface is covered with a layer of geosynthetic materials and a variety of plants are planted according to a certain combination and spacing. The purpose of root reinforcement and anti-erosion of stems and leaves can be achieved through plant growth activities.
After ecological slope protection technology treatment, dense vegetation cover can be formed on the slope surface, and intertwined roots can be formed in the topsoil layer, which can effectively inhibit the erosion of slope by storm runoff, increase the shear strength of soil, and reduce the pore water pressure and soil self-gravity.Thus, the stability and anti-erosion ability of the slope can be greatly improved.
Three-dimensional vegetation network slope protection technology not only significantly improves the overall and local stability of slope, but also facilitates the growth of slope vegetation. At the same time, the project cost is also low, which is in line with the development direction of slope engineering, and has great application value in soil and water conservation in China.

The anti-erosion effect of vegetation is realized through its three main components:
First, the growth layer of plants (including perianth, leaf sheath, leaf and stem) prevents the surface soil of slope from being directly eroded by rain through its own dense coverage, and reduces the erosion capacity and surface runoff speed of storm runoff, thereby reducing soil loss;
Second, the detritus layer (including the interface between leaf litter and rhizomes) provides a protective layer for the surface soil of the slope.
The third is the root layer, which reinforces and anchors the surface soil on the slope to provide mechanical stability.
Under normal circumstances, in the early stage of plant growth, because the roots formed by a single plant are only loosely tangled together, there is no long lying root system, easy to separate from the soil layer, and can not play a protective role.
The application of three-dimensional network is to enhance the effect of the above three aspects to achieve a more thorough shallow protection.One is to increase its protection performance and mechanical stability within a certain thickness range;Second, due to the existence of three-dimensional mesh, the huge root system of the plant is connected with the mesh of three-dimensional mesh, forming a plate structure (equivalent to the reinforcement of the surface soil of the slope), thereby increasing the tensile and shear strength of the protective layer, limiting the "gradual failure" caused by erosion (erosion causes direct damage to individual plants over time).
The expansion of the phenomenon will eventually limit the occurrence of shallow surface slide and uplift of the slope.
Geotechnical mesh mat slope protection technology synthesizes the advantages of geotechnical mesh and plant slope protection, and plays the role of composite slope protection. When the vegetation coverage rate of the slope reaches more than 30%, it can withstand the erosion of light rain, and when the coverage rate reaches more than 80%, it can withstand the erosion of heavy rain. When the plants grow lush, the runoff flow rate that can resist erosion reaches 6m/s, more than twice that of the general turf. The existence of geotechnical mesh has a good effect on reducing water evaporation of slope soil and increasing infiltration. At the same time, because the geomesh material is black polyethylene, it has the effect of heat absorption and heat preservation, which can promote seed germination and is conducive to plant growth.
Rapid protection measure
(1) When there is a contradiction between the construction period and the vegetation cultivation period, when the project enters the rainstorm season just after completion, it is necessary to adopt "reinforced turf" for rapid protection of the project, so that comprehensive coverage of anti-erosion vegetation can be obtained after completion. "Reinforced turf" adopts three-dimensional vegetation nets to pre-plant the turf in the lawn planting field or the open space near the construction site, and can be rolled up in whole or in pieces after forming the flat, and then laid on the slope to be protected.
(2) In the arid areas that are difficult to control, soil coagulants can be used to select suitable grass seeds, after special treatment, and mix with soil coagulants to spray (you can also sow grass seeds first, and then apply soil coagulants). After soil coagulant treatment, grass seeds and soil will not be lost due to wind and rain. At the same time, coagulant reduces the evaporation of water in the soil, which ensures the water supply of grass seeds to a certain extent and greatly improves the survival rate of grass seeds.
An alternative to concrete, asphalt, stone and other slope materials, mainly used for road, railway, channel, dam and other slope protection project.
1. Slope Treatment
Clean up the gravels and debris on the slope, fill the pot holes, compact and flatten the surface to ensure the slope surface is flat and smooth.
2. 3D Geomat Pavement
1) Unroll the 3D geomat along the slope from top to bottom and make sure the geomat perfectly fit to the slope.
2) An extra 40-80 cm geomat is required when burying 3D geomat on the top of the slope, bury it in soil and compact it.
3) Secure the 3D geomat with fastening nails or U staples.
4) When the 3D geomat pavement is finished, spread the soil evenly on the 3D geomat and ensure the soil thickness is not less than 12 mm. Mix the fertilizer, auxin and cement evenly by a certain proportion and then sprinkle on the surface
3. Spray- Seeding
When the soil backfill is completed, perform hydraulic spray seeding. Mix and stir the grass seeds and the adhesive, fertilizer, auxin, moisture agent and water that promote its growth evenly by a certain proportion, and spray the mixture evenly on the slope by hydraulic spray machine.
