Three-dimensional vegetation network is a new type of civil engineering material, which belongs to the reinforcing material in the field of new material technology in the national high-tech product catalogue.
Characteristic:
It is a kind of three-dimensional mesh mat with loosely textured and flexible structure for grass planting and soil consolidation. It has 90% space to fill soil, gravel and fine gravel. Root system of plant can grow comfortably, neatly and evenly through it. After growing, the surface of mesh mat, turf and soil can be firmly combined. Because the root system of plant can penetrate 30-30 below the surface. 40 cm, forming a solid green composite protective layer.
Functions:
1. Before the turf grows, it can protect the surface of the land from wind and rain.
2. It can firmly keep the grass seeds evenly distributed on the slope, so as to avoid being washed away by wind and rain.
3. Black mat can absorb a lot of heat energy, increase soil moisture, promote seed germination and prolong plant growth.
4. Because of the rough surface, wind and water produce numerous eddies on the surface of the mattress, which can dissipate energy and promote the sediment of its carriers in the mattress.
5. The composite protective layer formed by plants can withstand the erosion of high water level and high current velocity (3-4 m/s in two days and 5-6 m/s in four-5 hours).
6. It can replace permanent slope protection materials such as concrete, asphalt, block stone and so on. It can be used for slope protection of roads, railways, rivers, dams, hillsides and so on.
7. It can greatly reduce the cost of construction, which is 1/7 of the cost of C15 concrete and dry block stone slope protection and 1/8 of the cost of mortar block stone.
8. After laying the sand surface, the movement of sand dunes can be prevented, the surface roughness can be greatly improved, the surface sediments can be increased, the physical and chemical properties of the surface can be changed, and the local ecological environment can be improved.
