Base Reinforcement Pet Biaxial Grid For Road Construction Earthwork
Base Reinforcement Using Pet Biaxial Geogrid For Road Construction Earthwork
About Hengquan
We have experience for more than 7 years. There are two product lines for geogrid and geocell. Factory work 24hours a day, we sold more than 100,000,000rmb last year(2020). Our customers are all over the world.
The bidirectional geogrid is made of high molecular polymer through extrusion, plate forming, punching and then longitudinal and transverse stretching. The material has great tensile strength in both longitudinal and transverse directions. This structure can also provide a more effective force bearing and diffusion ideal interlocking system in the soil, which is suitable for large-scale permanent bearing. foundation.
The orientation of the arrangement strengthens the bonding force between the molecular chains and achieves the purpose of improving its strength. Its elongation is only 10% to 15% of the original sheet. If anti-aging materials such as carbon black are added to the geogrid, it can make it have better durability such as acid resistance, alkali resistance, corrosion resistance and aging resistance.
When laying geogrids, the direction of force is required to be perpendicular to the axis direction of the roadbed to ensure smoothness, tension, no bulge, and overlap according to the design width. First, use U-shaped rivets to fix, the main force direction of the grille, try to ensure that the whole length has no joints, and control the overlap width to be more than 20 cm; The overlap width should be controlled at more than 10 cm; if two or more layers of grids are used, the upper and lower layers should be staggered. After the large area is laid, adjust the straightness; try to shorten the time when the grille is exposed
After filling a layer of soil, before rolling, the grid should be tensioned again to ensure that the grid is in a state of tension and stress.

Product inventory:
In soft soil high fill engineering, laying geogrid in the middle of 30-50 cm gravel layer can form geogrid gravel cushion and give full play to the reinforcement role of excavated geogrid. On the one hand, the geogrid has strong shear resistance, which can effectively prevent the gravel from falling into the soft foundation, and promote the grid and gravel to be embedded closely to form a stable whole. On the other hand, the geogrid will form a horizontal plane in terms of drainage, which can be used as a drainage channel. After the subgrade is formed, it can effectively reduce the soil moisture content. Third, the geogrid is laid above the soft foundation, which will produce isolation effect,
It is not only convenient for construction, but also can restrain the lateral deformation of foundation and reduce uneven settlement. Fourth, increase the shear resistance of soil and change the physical and mechanical properties of soft foundation.
