PP geogrid is a kind of welding of polyethylene, polypropylene and enhanced tensile zone of reinforced fiber-reinforced, and then welded into a "#" character structure of the new environmentally friendly green building materials can be divided into single, double stick, weld geogrid grille. The product has high strength, deformation, corrosion resistance, long life, convenient construction, low cost, laying flat charge positioning, especially the permanent works to meet the various requirements more than 100 years. Rib belt line PP geogrid welding polymer plastic by extrusion stretch forming, with high tensile strength. Its vertical and horizontal ribs to the intersection with the high-frequency ultrasonic welding, to ensure the stability of product quality to ensure that the grille mesh inserts on the effective soil locks. Meanwhile grill ribs with tensile strength can be changed, the adjustment of the number of ribs designed with a different model specifications. To meet different project, which requires a variety of technical indicators. Performance: PP welding geogrids have high strength, low elongation (breaking elongation of not more than 12%) of the performance, while the amount of creep is small. Geogrid reinforcement, reinforcement of foundation, increase capacity, reduce differential settlement, and the impedance of the formation of surface soil damage. PP welding geogrid has good flexibility, because of the material by the strong stretching and transverse ribs with continuous two-sided clip, even if cracking, also remains geogrid performance. Applications: can be widely used in the construction of highways, railways, abutments, piers, slope, until the residue field of construction in soft ground reinforcement, reinforcement, strengthening and retaining wall and pavement crack engineering
