Bidirectional Plastic geogrid Polypropylene china railway Biaxial geogrid road paved geogrid
Product Description
PP Bi-axialGeogrid is manufactured from Polypropylene.It is produced through the process of extruding,punching,heating,longitudinal stretching and transverse stretching.
Product Features
High tension resistance, high plane torsion resistance modulus, good creep resistance and stable Chemical nature.
High mechanic damage resistance and durability and large friction factor with sandy stone.
It can improve bearing force of foundation (normal improvement of above 40%) and increase diffusion angle(average increase to 50 degrees from 38 degrees).
Under the function of shaft times with same load, it can decrease 30%-40% of filling thickness for reaching same effect, when technical grid reinforcement is used, road bed with same thickness can bear more 3-5 times.
Application
1.Reinforcement of road beds of various highways, railways and airports.
2.Reinforcement of permanent bearing road beds of large parking area and dock goods yard.
3. Slope protection and culvert reinforcement of railway and highway.
4. Secondary reinforcement of soil slope after uni-axial tension technical grid reinforcement
and further reinforcement of soil slope so as to avoid soil erosion.
5.Reinforcement of mile and gallery.
