Geogrid press product stress pattern is divided into two-way geogrid and unidirectional grille and press product of material composition is divided into glass fiber geogrid, synthetic fiber geogrid, poly propylene ethylene geogrid steel-plastic compound earthwork. In recent years poly propylene ethylene one-way geogrid in old road embankment are widely used in construction, it can effectively prevent and treat roadbed uneven settlement and longitudinal cracks and old pavement crack reflection.
PE/PP geogrids is made by the high polymer extrusion, two-way stretch and become, tensile strength, suitable for various kinds of soil, and its various performance indicators are better than the geotextile tensile of without nets, it is the most ideal reinforcement reinforcement material one. The grille can be widely used in highway, municipal roads, railways, runways) strengthen roadbed, highway, railway and rivers the coasts of retaining wall reinforcement engineering; Rivers and sea dike DAMS increase, Mine reinforcement and orchards, vegetable field, livestock, site fences, etc, with the TongJia machinery with global first coal production enterprise shenhua group successful cooperation of such products in the application of mine reinforcement got strong promotion .
