PP (Polypropylene) Biaxial Geogrid
Description
Two-way stretch plastic geogrid appearance approximate square network-like structure, which is made of polypropylene as the main raw material, by extrusion, and then vertical and horizontal stretching a high strength geotextile material. The material in the vertical and horizontal have great tensile strength, is widely used in soft foundation reinforcement treatment.
Specification
1. Strength : 15/15KN/M -- 50/50KN/M
2. Width: from 2m - 6m
3. Length: as request
4. Package: paper core, black waterproof membrane
5. Loading: 20ft container, 40ft high container
Applications
1, all kinds of roads, railways, airports roadbed enhancement;
2, permanent foundation bearing large car park and terminal freight yard and other enhancements;
3, railway, highway slope protection, culvert enhancement;
4-way stretch geogrid slope secondary enhanced enhanced, and further enhance the soil, prevent soil erosion;
5, mining, tunnel reinforcement.
Construction method
Excavation of foundation bed, set the sand cushion (height of not more than 10cm), rolled into the platform, laying grille, the vertical axis to be consistent with the direction of the main force, longitudinal lap 15-20cm, lateral 10cm, lap banding with plastic tape and laying on the grill every 1.5-2m with U-nails on the ground, laying geogrid should be promptly backfill material, laying geogrid layers depending on the technical requirements.
