PP Unidirectional geogrid
Product introduction
Uni-direction plastic geogrid is a kind of geotechnical material with high strength that made by high molecule polymer as main material, adding certain ultraviolet proof and aging resistance agent. It makes directional tension under certain temperature condition according to physical features of high molecule polymer,so its strength is very high in tension direction ,tension resistance reaches 100-200 mpa ,yield elogation rate is only 4-10 percent , it is near to the level of low steel and much better than traditional or current reinforcement materials ,and is very ideal synthetic material for strengthening and reinforcement of civil projects
Product features
high unidirectional tension resistance ,gogod creep resistance and stable chemical nature
it has large friction factor with sandy stone .
it is mainly used in retaining wall ,bridge abutment ,sleep slope project and so on
retaining wall and bridge abutment belong to force bearing structures and bear all external loads such as active soil pressure ,support of structure upper part and temperature stress ,under the function of large tension and repeated function of dynamic load ,molecule structure of reinforcement material occurs fatigue,its performance occurs attenuation and aging of grid quickens. In order to avoid large deformation of structure caused creep of reinforcement material ,undirectional geotechnical grid with high destity HDPE as raw material shall be used
