1, What is the bidirectional stretching plastic geogrids:
Bidirectional stretching plastic geogrids are polypropylene (PP) or polyethylene (PE) as raw material, plasticized extrusion sheet, punching, heating, longitudinal stretching, transverse stretching.
2, What are the characteristics of bidirectional tensile plastic geogrid:
The bidirectional tensile plastic geogrid has great tensile strength both longitudinally and laterally. This structure can provide an ideal interlocking system of more effective force bearing and diffusion in soil, and is suitable for foundation reinforcement with large area permanent load.
3, The engineering application of bidirectional stretch plastic geogrid:
Plastic geogrid suitable for reinforcing all kinds of embankment and roadbed, slope protection, cave wall reinforcement, permanent bearing foundation reinforcement of large airports, parking lots, wharfs and freight yards.
1). Increase the bearing capacity of road (ground) foundation and prolong the service life of road (ground) foundation.
2). Prevent road (ground) surface collapse or crack, keep the ground beautiful and tidy.
3). Convenient construction, time saving, labor saving, shorten the construction period, reduce maintenance costs.
4). To prevent cracks in culverts.
5). Enhance soil slope to prevent soil erosion.
6). Reduce cushion thickness and save cost.
7). Support the stable green environment of slope grass mat.
8). Plastic geogrid can replace metal mesh and be used for false roof mesh in coal mine.
