Geogrid standard geogrid price geogrid role
Geogrid is a kind of main geosynthetics, which has unique properties and effects compared with other geosynthetics. Geogrid is often used as reinforcement of reinforced soil structure or composite material. Geogrid is divided into four categories: plastic geogrid, steel plastic geogrid, fiberglass geogrid and fiberglass polyester geogrid.

plastic geogridThe plastic geogrid is a kind of polymer material with square or rectangular shape which is formed by stretching, and it can be used as two kinds of uniaxial tension and biaxial tension. The utility model is punched on the extruded polymer plate (raw material is polypropylene or high-density polyethylene), and then directionally stretched under the heating condition. The unidirectional stretching grid is only drawn along the length direction of the plate, and the bidirectional stretching grid is made by stretching the unidirectional stretching grid in the direction perpendicular to the length. As the polymer in the manufacture of plastic polymer in the process of heating with the extension of the process of re orientation, strengthen the link between the molecular chain force, to achieve the purpose of improving its strength. Its elongation rate is only 10% ~ ~ of the original plate of 15%. If the carbon black and other anti-aging materials are added in the geogrid, the utility model has the advantages of good acid resistance, alkali resistance, corrosion resistance, aging resistance and the like. The bidirectional geogrid two-way geogrid is made of high molecular polymer through extrusion, plate forming, punching process and then longitudinal and transverse stretching. The material has great tensile strength in both longitudinal and transverse directions, the chain system of this structure in the soil can also provide a more effective force to bear and spread of the ideal, to adapt to the foundation of unidirectional geogrids uniaxial geogrid in the large area of a permanent load is a polymer by extrusion pressure a thin plate and punching network rules, and then the longitudinal stretch. This process make the linear polymer into a state of orientation and form long oval mesh structure integrity and uniform distribution of nodes with high intensity. The structure has very high tensile strength and tensile modulus,.
