Bi-direction plastic geogrid,made of high molecular polymer,is formed through extrusion into sheet,punching,and vertical and horizonal stretching.It has great tensile strength in both vertical and horizonal directions.As its structure can also provide an ideal chain system of more effective force bearing and spreading for the soil,it is applicable to the reinforcemant of permanent load-carrying foundation of large areas.
Applications
Bi-direction plastic geogrid is applied for the fake ceiling and wall supporting in coal mine& underground supporting project,the side slope protection,enhancement of embankments and subgrades,wall reinforcement,as well as the reinforcement of permanent load-carrying foundation of airports,parking lots,and wharf freight yards.
Advantage
High-strength:The tensile strength is higher than that of the diamand mesh,and it can replace the diamand mesh.
Innovation:Weave the high-strength material by the plastic and mesh joint is firm
Low extension:Low unit extension,average stress,and avoid the apprearance of the tuck net effictively.
Light:Weigh about 1kg/m².Reduce the labor intensity,improve the working efficiency,and simple to install and use.
Safety:Static resistant,inflaming retarding,avoid the appearance of the electric sparkle effectively.
Erosion resistance:Its plastic surface ensure long service life and no invalidation caused by the ecrosion.
