Detailed Description

Features: 1) Can replace concrete, asphalt, stone and other slope protection material 2) Mainly applied to slope of road, railway and river lane, dams and dikes, and mountain slope 2) Can prevent land soil from water and rain erosion before grass covering grows 3) Can bear sourcing of high water space and high-speed water after grass covering grows 4) It can reduce cost of construction by width margin and the cost is only 1/7 concrete, 1/8 stone 5) It adopts macromolecule material and anti-UV rays stability, and its chemical character is very stable, and there is no pollution to environment 6) Easy construction after surface of land is smooth 7) A kind of three dimensional structure new-type geosynthetical materials suitable for protecting water and land soil 8) Can effectively prevent water and land soil from flowing away, increase green land and improve living environment Operation: 1) Can use bamboo pole or wood stick pass the whole roll net mat during construction, then pull net mat along slope, use wooden nail or plastic nail to fix four circle of net mat, distance between nails is 30cm, one square meter has 10 nails 2) Length of nail from land surface is usually 15cm, add nails on loose land, length of nail on up slope is longer than on down slope when construction on high slope 3) Pay attention to keep netting mat smoothly and add nails on sudden change place topography 4) Check carefully connecting. Length of connecting is 2cm, nail must be fixed in connecting place, nails density is added 100%, there is no internal and keepnet 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 5) Depth of sowing takes actions that suit local circumstance, chose long root and suitable for local climate of grass seeds 6) Grass seeds sows in net mat, so can improve result of complex protect coating 7) After sowing, land soil must cover the netting mat. 8) After sowing, 40-50% water proportion in land soil is reasonable, and adding pressure on surface of land, so benefit for grass seed's growing 9) Longitude of connecting should have 60-degree angle, netting mat must be buried into land soil 30cm when laying on up slope. Bottom of slope should higher than level land. Also, open a ditch 20cm from up slope, so can easily irrigate 10) Lying time is earlier 3-4 months than rain season Note: 1) Don't apply to surface of gravel 2) Please choose to use less than 45-degree angle slope 3) Don't apply to against-sea situation 4) Only apply to planting seeds for protecting slope, no making deepen tendon-added material 5) Lying time is earlier 3 months than rain season when use in against-river situation, which can guarantee the grass cover firmly form in or above normal water degree Geonet Item Unit CE111 CE121 CE131 CE131B CE151 Width m 2.5 2.5 2.5 2.5 2.5 Tensile strength kN/m 2.0 7.68 5.80 6.40 1.82 Elongation at max strain % 41.0 20.2 16.5 18.6 23.2 Tensile strength at 10% strain kN/m 1.32 6.80 5.20 5.74 3.83 Notes: Application for special stipulated in contract will be available Geomat Item Unit EM3 EM3 EM4 EM5 Thickness mm 10 12 14 16 Longitudinal tensile strength kN/m 0.8 1.6 2.0 3.2 Transversal tensile strength kN/m 0.8 1.6 2.0 3.2
