Uniaxial geogrid introduction
1,High unidirection tension resistance, good creep resistance and
stable chemical nature.
2,It has large friction factor with sandy stone.
1,It is mainly used in retaining wall, bridge abutment, steep slope
project and so on.
2,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
by creep of reinforcement material, unidirectional geotechnical
grid with high-density polyethlene(HDPE) as raw material shall be
