What is uniaxial geogrid? A uniaxial geogrid is made with HDPE (high-density polyethylene) and produced by extruding the material into thin sheet, punching a regular pattern of holes in the sheet, and drawing it longitudinally.
What are the characteristics of uniaxial plastic geogrid?
1. The polymeric macromolecules, regularly oriented and linearly arranged, are formed to elliptical grid-like integral structure with high node strength. Such a structure has high tensile strength and high stiffness. Therefore, it is an ideal product for load support and stress distribution in soil-reinforcement applications.
2. Unidirectional plastic geogrids have a unique characteristic of small creep deformation under long-time permanent load, with much higher creep strength than geogrids made with other materials, and thus can increase the lifespan of engineering works.
3. Geogrids are interlocked with soils to form an effective stress distribution mechanism. In other words, a concentrated load can be quickly and effectively distributed to a large area of subsoil and thus the local stress is reduced.
4. Engineering applications of uniaxial plastic geogrid:
5. Unidirectional plastic geogrid is a high-strength geosynthetical material, widely used in such applications as river embankment, tunnel, dock, road, railway and buildings.
1. What is biaxial plastic geogrid?
A biaxial plastic geogrid is made with PP (polypropylene) or PE (polyethylene) and produced by plastifying and extruding the material into sheet, punching a pattern of holes in the sheet, and heating and stretching the punched sheet longitudinally and transversely.
2. What are the characteristics of biaxial plastic geogrid?
biaxial geogrid has high tensile strength both longitudinally and transversely and are an ideal product for load support and stress distribution in soil reinforcement applications,especially large foundations requiring permanent load support.
3. Engineering applications of biaxial plastic geogrid
biaxial plastic geogrids are suited to reinforcement of foundations requiring permanent load support, such as river embankment, road subgrade and side slope, tunnel wall, airport, parking lot, and dock.
