uniaxial plastic geogrid for road reinforcement

Uniaxial plastic geogrid introduction

Uniaxial plastic geogrid refers to high-density polyethylene (HDPE) as raw material, plasticized extruded sheet, punched, heated, stretched, extruded and pressed, thin plate re-punched regular hole net, then longitudinal Stretched geogrid. Generally used for laying in the soil, through the meshing and interlocking between the geogrid mesh and the soil, constitutes an efficient stress transmission mechanism, so that the local load can be quickly and effectively diffused into the large area of the soil. In order to reduce the local damage stress and improve the service life of the project.

Characteristic of Uniaxial plastic geogrid

1. The polymer is oriented in a linear state and forms a long elliptical network-like integral structure with uniform distribution and high joint strength. This structure has a relatively high tensile strength and rigidity, providing the ideal combination of force bearing and diffusion for the soil.

2. The outstanding advantage of the one-way plastic geogrid is that the tendency of deformation (creep) under long-term continuous load is small, and the creep strength is much better than the geogrid of other materials, which plays an important role in improving the service life of the project. .

3. The occlusion and interlocking action between the grid mesh and the soil constitutes an efficient stress transmission mechanism, so that the local load can be quickly and effectively diffused into the large-area soil, thereby reducing the local failure stress. To improve the life of the project.

4. Enhance the roadbed, effectively distribute the diffusion load, improve the stability and bearing capacity of the roadbed, and extend the service life;

5. Can withstand more alternating load; 3. Prevent roadbed deformation and cracking caused by loss of roadbed material;

6.Improve the self-supporting ability of the backfill behind the retaining wall, reduce the earth pressure of the retaining wall, save costs, extend the service life, and reduce maintenance costs;

7.Slope maintenance combined with spray anchor concrete construction method can not only save 30%-50% investment, but also shorten the construction period by more than double;

8.Add geogrid to the roadbed and surface of the road to reduce deflection, reduce rutting, delay the occurrence of cracks by 3-9 times, and reduce the thickness of the structural layer by 36%;

9.It is suitable for all kinds of soils, no need to take materials from different places, saving labor and time;

10. Construction is simple and fast, which can greatly reduce construction costs.
