product description:
One-way plastic geogrid is formed by extruding high molecular polymer into thin plate, punching regular mesh, and then stretching longitudinally. In this process, the macromolecules are brought into a directional linear state and an oblong network-like integral structure with uniform distribution and high node strength is formed. This kind of structure has quite high tensile strength and tensile modulus (elongation rate is 2%-5%), which provides the ideal force bearing and diffusion interlocking system for the soil. The product has high tensile strength (>150Mpa) and is suitable for various soils. It is a widely used reinforcement material.
Features:
1. Strengthen the roadbed, which can effectively distribute the diffusion load, improve the stability and bearing capacity of the roadbed, and prolong the service life;
2. Can withstand greater alternating loads;
3. Prevent roadbed deformation and cracking caused by the loss of roadbed materials;
4. Improve the self-supporting capacity of the fill behind the retaining wall, reduce the earth pressure of the retaining wall, save costs, prolong the service life, and reduce maintenance costs;
6. Adding geogrids to the roadbed and surface layer of the highway can reduce deflection, reduce rutting, delay the appearance of cracks by 3-9 times, and reduce the thickness of the structural layer by 36%;
7. Applicable to all kinds of soil, no need to obtain materials from different places, saving labor and time;
8. The construction is simple and fast, which can greatly reduce the construction cost.
Product Usage:
Mainly used for retaining walls, bridge abutments, steep slope projects, etc.;
Retaining walls and abutments belong to stressed structures and bear all external loads: active earth pressure, dynamic load on the upper part of the structure, temperature stress, etc. The reinforced material is under the action of large tension for a long time, and the repeated action of dynamic load Under this condition, the molecular structure of the material is fatigued, its performance is attenuated, and the aging of the grid is accelerated. In order to avoid the large deformation of the structure due to the creep of the reinforced material, a one-way plastic geogrid made of high-density polyethylene (HDPE) should be selected.
