Uniaxial Plastic Geogrid

Uni-axial Geogrid for Road (ground) Base Description：

Unidirectional plastic technical grid is a kind of technical material with high strength that uses high molecular polymer as

main raw material, adds certain ultraviolet proof and aging resistance agent and makes messy chain shape molecules have

directional layout and from linear status by unidirectional extension. Plastic technical grid 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 100-200Mpa, yield elongation rate is only 4-10%, it is near to the level of low carbon steel

and much better than traditional or current reinforcement materials, and is very ideal synthetic material for strengthening and

reinforcement of civil projects.

Feature：

 1. High unidirectional tension resistance, good creep resistance and stable chemical nature.

 2. It has large friction factor with sandy stone.

Application：

 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 technical grid with high-density polyethylene (HDPE) as  raw material shall be used.
