PP Biaxial Geogrid
Product Introduction
The outlook of the biaxial geogrid is net work structure like a square. It uses polyester as its raw material and is made of high molecular polymer through extrusion, formed and punched before longitudinally and laterally stretched. This kind of material has a high tensile longitudinally and horizontally, which can be used to reinforce the basement.
Production function
1. It can be applied in all kinds of roads, airports to enhance the roadbed;
2. It can be applied in a large car park and terminal freight yard, etc. To strengthen the foundations of a permanent load;
3. It can be applied in rail, road slope's protection;
4. It can be applied to enhance the culvert;
5. It can be applied as a secondary enhancement after the uniaxial Geogrid soil enhancement, further enhance the soil;
6. It can be applied in mining, tunnel reinforcement.
7. Network used for animal and husbandry;
8. Network used for cage fishing.
Using the finite element method to treat the reinforcement of the biaxial geogrid to the bridge and roadbank to research the problem of controlling car's jump from the end of the bridge. It can analysis the effective rule that the reinforced embarkment layer spacing to the settlement of the roadbank, the additional vertical stress distribution, the geogrid tensile stress. The results show that a reasonable program for reinforced embankment of the bridge can effectively control the bridge embankment settlement and make the bridge between the bridge and the embankment settlement to smooth the transition for control of the bridge have created favorable conditions for jumping.
