Uniaxial plastic geogrid refers to high-density polyethylene (HDPE) as raw material, plasticized extruded sheet, punched, heated, stretched, extruded and pressed, thin plate re-punched regular hole net, then longitudinal Stretched geogrid. Generally used for laying in the soil, through the meshing and interlocking between the geogrid mesh and the soil, constitutes an efficient stress transmission mechanism, so that the local load can be quickly and effectively diffused into the large area of the soil. In order to reduce the local damage stress and improve the service life of the project.
Geogrid can be used to enhancement of permanent bearable soft including highway and railways embankment, slopes, tunnel, airport, parking lots, loaded pier and ground and their main usage are as follows:
1. Geogrid Enhance the bearing capacity fo road foundation and extend the duration of highway.
2. Geogrid Prevent highway surface from collapse, crack and being dirty.
3. Geogrid Be convenient for construction timesaving and cut down the cost of maintenance.
4. Geogrid Prevent tunel from crack occuring
5. Geogrid Further solidity slopes to proof water and soil from losses
6. Geogrid Reduce the surface thickness of the ground.
7. Geogrid Consolidate the net for growing grass on the slopes so as to stabilization surrounding virescence.
8. Geogrid Be used for artificial top net of mines instead of metal ones. It is of flame retardant and antistatics.
4. It is a kind of high strength geomaterial which has been applied in highway, railway, building area, etc, it has the characteristics as following:
1.Enlarge road loading; lasting the life of road;.
2.Bear the greatest loading change;
3.Prevent the road from cracks and deformation;
4.Reduce the protection fares;
5.Convenient construction, low costs.
