One-way plastic geogrid is made of polymer extrusion and pressed into thin plates, punched in regular hole mesh, and then stretched longitudinally. In this process, the polymer is in a directional linear state and forms an oblong network-shaped integral structure with uniform distribution and high node strength. This structure has a very high tensile strength and tensile modulus, providing the soil with an ideal force-bearing and diffusion chain system. It has a high tensile strength (>150Mpa), adapted to various soils, and is a reinforced reinforcement material widely used.

Features

1. Strengthen the roadbed, which can effectively allocate diffusion load, improve the stability and bearing capacity of the roadbed, and extend the service life;
2. Can withstand greater alternating loads;
3. Prevent the roadbed deformation and cracking caused by the loss of roadbed materials;
4. Improve the self-supporting capacity of soil filling behind the retaining wall, reduce the soil pressure of the retaining wall, save costs, extend service life, and reduce maintenance costs;
5. Combined with the spray anchor concrete construction method for slope maintenance, it can not only save 30%-50% of investment, but also shorten the construction period by more than twice;
6. Adding geogrids to the roadbed and surface layers of the highway can reduce bends, reduce ruts, delay the occurrence time of cracks by 3-9 times, and reduce the thickness of the structural layer by 36%;
7. Suitable for all kinds of soils, no need for materials from other places, saving labor and time;
8. The construction is simple and fast, which can greatly reduce construction costs.

Table parameters

One-way plastic geogrids implement the national standard of the People's Republic of China "GB/T 17689-2008 Geosynthetic Materials Plastic Geogrid", which was released on March 25, 2010 and officially implemented on July 1, 2010.

Application Description:

One-way stretched geogrid is a high-strength geosynthetic material. It is widely used in dams, tunnels, docks, roads, railways, construction and other fields. It is mainly used in retaining walls, abutments, steep slope projects, etc.; retaining walls and abutments belong to stressed structures, which bear all external loads: active soil pressure, dynamic load on the upper part of the structure, temperature stress, etc. The reinforced materials are under large tension for a long time, and the repeated action of dynamic loads, the molecular structure of the material is fatigued, its performance decays, and accelerates the aging of the grid. To avoid large deformation of the structure due to creep of the reinforced material, a one-way plastic geogrid with high-density polyethylene (HDPE) as the raw material should be selected.
