Uniaxial tensile plastic geogrid

Uniaxial tensile plastic geogrid is a high-strength geosynthetic material. It is made of high-density polyethylene (HDPE) as a raw material, extruded and pressed into a thin plate, punched into a regular mesh, and then stretched longitudinally. It is widely used in dams, tunnels, docks, highways, railways, construction and other fields.

  • Uniaxial tensile plastic geogrid
    Uniaxial tensile plastic geogrid is a high-strength geosynthetic material. It is made of high-density polyethylene (HDPE) as a raw material, extruded and pressed into a thin plate, punched into a regular mesh, and then stretched longitudinally. It is widely used in dams, tunnels, docks, highways, railways, construction and other fields.

    characteristic
    1. The polymer is in a directional linear state and forms a long oval network-like integral structure with uniform distribution and high node strength. This structure has a relatively high tensile strength and rigidity, providing the soil with an ideal interlocking system for force bearing and diffusion.
    2. The outstanding advantage of unidirectional plastic geogrid is that it has little tendency to deform (creep) under long-term continuous load, and its creep resistance is much better than that of geogrids made of other materials, which plays an important role in improving the service life of the project .
    3. The occlusal and interlocking effect between the grid mesh and the soil constitutes an efficient stress transmission mechanism, so that the local load can be quickly and effectively spread to a large area of the soil, thereby reducing the local failure stress , The purpose of improving the service life of the project.

    Engineering Applications
    1. Strengthening the roadbed 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 roadbed material loss;
    4. Improve the self-supporting capacity of the filling behind the retaining wall, reduce the earth pressure of the retaining wall, save costs, prolong the service life, and reduce maintenance costs;
    5. Combining the construction method of shotcrete anchoring for slope maintenance can not only save 30%-50% of investment, but also shorten the construction period by more than double;
    6. Adding geogrid to the subgrade and surface 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 various soils, 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.
     
    Construction method
    1. When used on subgrades and road surfaces, excavate the foundation bed, set up a sand cushion (height difference is not greater than 10cm), roll it into a platform, and lay grids. The longitudinal axis should be consistent with the main force direction, and the longitudinal overlap 15-20cm, 10cm horizontally, the lap joints are tied with plastic tape, and fixed to the ground with U-shaped nails every 1.5-2m on the laid grid, the laid geogrid should be backfilled with soil materials in time, and the laid geogrid The number of grid layers depends on the technical requirements.
    2. When used in reinforced soil retaining walls:
    1. Set up the foundation and carry out construction according to the designed wall system. When prefabricated reinforced concrete panels are selected, they are usually supported on the prefabricated concrete foundation with a thickness of 12-15cm. Its width is not greater than 30cm, its thickness is not less than 20cm, and its buried depth is not less than 60cm to prevent the foundation from being affected by frost heave;
    2. Level the wall foundation, excavate and level it according to the design requirements. The soft soil needs to be compacted or replaced, and compacted to the required density, it should be slightly beyond the range of the wall;
    3. For the laying of the reinforcement, the main strength direction of the reinforcement should be perpendicular to the wall and fixed with pins;
    4. Fill the wall with mechanical filling. The distance between the wheel and the reinforcement should be kept at least 15cm, and the thickness of a layer of soil after compaction should be about 15-20cm.
