Geo-Grid-

IntroductionGeo-grid is a high-strength structural material which contains macromolecule polymer as main raw materials with addition of some anti-ultraviolet and anti-aging auxiliary agents and provides molecular structure realigned in vertical and horizontal direction by means of the workmanship control in the process of fabrication, including stretched single geo-grid (TGDG series) and stretched bidirectional geo-grid (TGSG series).Stretched single geo-grid is a synthetic material used for strengthening and reinforcement of civil works, in which macromolecule polymer is adopted as main raw materials, some anti-ultraviolet and anti-aging auxiliary agents are added and orientation is made through deeply stretching, being characterized by high strength and low extension.Stretched bidirectional geo-grid is a high-strength structural material, in which molecular structure is realigned in vertical and horizontal direction with high tensile strength in the process of fabrication. Performances Provide the integrative structure and high strength for nodeProvide high tensile yield strength and low elastic strain to ensure geo-grid has high tensile strength in the low elastic strain;Ensure no deformation with good creep resistance under the continuous load for long time;Provide high friction coefficient (approximately 0.8) and strong acting force for mud and sand, stone and concrete to prevent slippage;Provide stable chemical property, corrosion resistance against such organic solvents as acid, alkali, salt solution or gasoline and diesel fuel;Geo-grid can not be dissolved by water, free of cracking caused by environmental stress and damage from micro-organismLight, convenient for transportation and construction, low maintenance fee;Provide anti-aging and above 120 years service life under load. Application: Reinforcement for subgrade of road and railway, protection for dome, prevention against soil and water loss, repair for collapse and landslide of slope, treatment for soft foundation of road, reinforcement for embankment foundation, reinforcement for retaining wall and abutment, works of landfill site and laying of pipeline.Model and technical parameters Stretchedsinglegeo-grid: Item TGDG25 TGDG35 TGDG50 TGDG80 TGDG110 Massinunitareag/m 2 370±50 450±50 550±50 700±50 1100±50 Widthm 1.0or2.0 Stretchedbidirectionalgeo-grid: Item TGSG15-15 TGSG20-20 TGSG30-30 TGSG40-40 TGSG45-45 Massinunitareag/m 2 300±30 330±30 400±40 500±50 550±50 Widthm 4.0 Notes: As generally KAILE geo-grid is long 50m/piece, or customized. HDPE (high density polyethylene)geo-grid is characterized by favorable anti-low temperature and widely used for high and cold zone. PP (polypropylene) geo-grid is characterized by favorable anti-cracking caused by environmental stress and used at -23 70.
