The 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.
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
The civil grille is also called the geogrid, which is made of polypropylene, polyvinyl chloride and other high molecular polymer, which is made of thermoplastic or molded two dimensional grid or a three-dimensional grid screen with a certain height,
