It is a kind of new 3D structural geotechnical synthetic material, which is applied to keep the water and land

It is a king of new 3D structural geotechnical synthetic material, which is applied to keep the water and land, increase the greening area, and improve the environment.(1)Replace the concrete, asphalt, and block, using in the slope surface protection of roadway, railway, river-way, dyke, and the hillside, etc.(2)Before the greensward grows, it prevents the surface of the land from the erosion of the wind and rain (3)Form compound protection layer with the vegetable, standing the wash-out of the high water level and large speed current.(4)Decrease the engineering cost greatly; its cost is 1/7 of that of the concrete and stone pitching slope protection, and 1/8 of that of the wet masonry rock block slope protection. (5)Adopt polymer material and the ultravioresistant stabilizer, higher chemical stability, no pollution to the environment. (The degrading net pad has no any track in the earth for 2 years)(6)Simple to construct: after leveling off the earths surface, and then construct. (1)start construction can wear with the small bamboo pole or small wood rods in in the whole net mat, follow the land to pull up the net mat, on all sides nail with the bamboo, the nog or plasticses nail, nail be apart from the 30 cms,10 per square meter nail.(2)the nail length generally for 15 cms( the distance ground), the sparse and loose earth's surface then should lengthen the nail length, at the high land build, the nail length of the up slope usage should be longer than under the length of the nail of the land. (3)complicated place of the geography mutation place or geographies, should note to protect Hold the net mat neat, and to increase the nail density.(4)notice to take to connect.Take to connect the length 2 cms, take to connectA nail should comply with the surrounding to nail to go into, the nail density adds to increase 100%,Take to connect an upper level  net mat to want to depend tightly, don't stay the cleft. (5)the shape of the nail, the nail top end width is should be big in the net mat  bore path 200%, in order to rise the perpendicular suppression function at the same time.(6)the grass seed sow seeds depth should according to the soil éê feeling, settle because the ground system is proper, the grass grows and should choose in keeping with local weather condition, root the department is long, and the flourishing grass grow, have a department of many year living the small bush to grow better.(7)the grass grow to sow seeds the depth and should can strengthen compound result of the protection layer thus and more in the net mat.(8)after the grass seed sow the , the topsoil overlay depth should take covering up the net mat as the lord.Doing not make the net mat expose in the sun, use the time limit forthe convenience of the extension.But must notice the germination and the growth of be advantageous to the grass seed.(9)after the grass seed sow seeds, the soil layer contain the amount of water and should take 40-50% as proper, and add to press in the soil surface layer, to be advantageous to the grass seed germination.(10)the net mat at the protection top build, the net mat link the place and should have lengthways 60.Clip the Cape, cover up to bury the medium 30 cms.The up slope bottom should have the 50 cms the above horizontal plane.Because engineering in the faces the top end to contain the amount of water to want to be lower than bottom layer and have to have another, disadvantage in the grass seed germination, should at leave up slope crest of the net mat 20 cms the agreeable mat open a retain water ditch, in order to in infuse the water.(11)build the opportune moment, is the whole key( at protect up slope up usage) of engineering, should choose generally at raining season ex-3-4 months carry on, let sod have living certainly long time.
