A kind of three dimensional structure new-type geosynthetical material suitable for protecting water and land soil, can effectively water and land soil flowing away, increase greenland of measure of area, improve living environment.

Usage:

Can instead of conctete, asphalt, stone and other slope protection material, mainly apply to slope of road, railway and river lane.Dams and dikes, mountain slope, ete .
Can prevent land soil from water and rain erosion before grass covering grows.
Can bear sourcing of high water space and high-speed water after grass covering grows.
Can reduce cost of construction by a width margin, cost is only / concrete, / stone.
Adopt mactomolecule material and anti-uv rays stability, its chemical chatacter is very stable, no pollution to environment.
Easy construction after surface of land is smooth.

Operation:

Can use bamboo pole or wood stick pass the whole roll net mat when construction, then pull net mat along slope, use wooden nail or plastic nail to fix four circle of net mat, distance between nails is cm, one square meter has nails.
Length of nail from land surface is usually cm, add nails on loose land, length of nail on up slope is longer than on down slope when construction on high slope.
Pay attention to keep netting mat smoothly and add nails on sudden change place topography.
Check carefully conneeting .Length of conneeting is cm, nail must be fixed in connecting place, nails, density is added %, there is no internal and keep net mat closely on up net mat, width of bore diameter on up nail is two times of netting mat hole, so can suppress on vertical direction.
Depth of sowing takes actions that suit local circumstance, chose long root and suitable for local climate of grass seeds.
