PP bidirectional welded geogrille (plastic Composite Ribbed grille): is a high strength strip produced by polypropylene (PP), which is welded into a network of geosynthetics through vertical and vertical joints. Mainly used for soft soil foundation treatment, dike construction, slope reinforcement and so on.
The ribs of PP welded geogrids are made of polymer plastics by extrusion and stretching, and have high tensile strength. The joints of longitudinal and transverse ribs are welded by high frequency ultrasonic wave, which ensures the stability of product quality and the effective interlocking of grids to soil. At the same time, the strength of the grille can change the tension of ribs and adjust the number of ribs to design different models and specifications. To meet the needs of different projects and technical indicators.
Properties of PP Welded Geogrid Products:
PP geogrids have high strength, low elongation (breaking elongation is not more than 12%) and little creep. Grille reinforcement, reinforcement of foundation, increase bearing capacity, reduce uneven settlement, and impede the formation of soil failure surface.
PP geogrids have good flexibility, because the material is continuously stretched and transverse ribbed double-sided clamp, even if cracked, it still maintains the performance of geogrids.
Friction coefficient:
The surface of the product is treated and pressed with rough patterns to enhance its roughness. At the same time, the mesh formed by the longitudinal and transverse ribs interlock the soil to achieve the optimal passive impedance force on the soil.
The width of PP geogrid can reach 2-6.5 meters and the length of equal coil can reach 50 meters (also can be produced according to user's demand).
Applications:
It can be widely used in the construction fields of highway, railway, abutment, wharf, slope protection, slag yard and so on.
