Soil surface erosion prevention

Before the grass grows, it can protect the embankment from wind and rain erosion.. Grass seeds can be evenly distributed on the slope to prevent dissipation due to wind and rain Heat absorption and constant temperature

Mesh mats can absorb heat energy, enhance ground temperature, and prolong the growth period of plants by allowing grass seeds to germinate 

Anti erosion

The composite protective layer formed by the growth of plants can withstand high water levels and high flow rates of water erosion 

It can replace other materials with low cost

It can replace slope materials such as concrete and asphalt blocks, mainly used for slope protection on highways, railways, rivers, embankments, etc 

It is both environmentally friendly and convenient for construction

It can create a green slope ecological environment and absorb noise. Construction is simple, and after leveling the surface, construction can begin

1. The purpose of root reinforcement and erosion prevention of stems and leaves can be achieved through plant growth activities. Through ecological slope protection technology, lush vegetation coverage can be formed on the slope surface, and complex roots can be formed in the topsoil layer, effectively preventing the corrosion of rainstorm runoff on the slope, increasing the compressive strength of the soil, reducing the pore water pressure and soil self gravity, and improving the stability and erosion resistance of the slope.

2. When the vegetation coverage rate of the slope reaches more than 30%, it can withstand the scouring of light rain, and when the coverage rate reaches more than 80%, it can withstand the scouring of rainstorm. When the plants grow vigorously, the runoff flow rate that can resist erosion can reach 6m/s, which is more than twice that of ordinary grass.

3. The filling material of the mesh bag can be well fixed, and the root system of the growing grass is connected to the mesh reinforcement of the three-dimensional mesh, forming a plate structure, which is equivalent to adding reinforcement to the surface soil of the slope, making the slope soil layer, three-dimensional mesh, and lawn jointly form a slope protection system

Protect the slope surfaces of highways and railway embankments to address common rainwater erosion issues. Widely used in various slope protection projects such as embankments, cuttings, borrow areas, spoil piles, community greening, and ditch erosion.

1. Preparation before construction: Slope treatment

Clean up the miscellaneous stones and debris on the slope, backfill and compact the low-lying areas to ensure a smooth slope surface.

2. Laying a three-dimensional network

(1) Pave the three-dimensional vegetation network along the slope surface from top to bottom, and maintain a smooth connection between the network and the slope surface.

When pre embedding the three-dimensional mesh on the top of the slope, it needs to be extended by 40-80cm, buried in the soil and compacted.

(3) Anchor the three-dimensional network from bottom to top ф The three-dimensional mesh is fixed with U-shaped steel bars of 6mm or more, with a length of about 15-30cm and a width of about 8mm. The spacing between U-shaped steel bars is about 1.5-2.5m, and 8 # U-shaped iron nails or bamboo nails are used as auxiliary fixation in the middle.

After the laying of the three-dimensional vegetation network with soil covering, evenly cover the soil on the three-dimensional vegetation network, cover the network until there are no empty packages, and ensure that the soil thickness on the three-dimensional vegetation network is not less than 12mm. Then mix the fertilizer, auxin, and binder in a certain proportion evenly and sprinkle them on the surface.

3. Spray sowing

After the backfilling of the soil is completed, hydraulic spraying is carried out, which involves mixing and stirring the grass seeds and the adhesion agents, wood fibers, fertilizers, auxin, moisturizing agents, and water that promote their growth in a certain proportion to form a uniform mixture. The mixture is then evenly sprayed on the slope through a hydraulic spraying machine.

4. Coverage

After the completion of spraying and grass planting construction, cover the surface of the slope with non-woven fabric to maintain moisture on the slope surface and reduce the erosion of seeds by rainfall, promoting seed growth. If the temperature is too high, there is no need to cover it to prevent the occurrence of diseases and pests.

5. Maintenance management

After the completion of grass spraying construction, it is necessary to regularly maintain the lawn until it is flat. When the lawn grows to about 5cm, the non-woven fabric can be removed.
