塑料土工格栅 (1) Plastic geogrid   Plastic geogrids are square or rectangular polymer meshes formed by stretching. There are two types of unidirectional stretching and biaxial stretching according to the stretching direction during the manufacturing process. It is punched on a polymer sheet (mostly polypropylene or high-density polyethylene) produced by extrusion, and then subjected to directional stretching under heating conditions. single   Stretching grid is made by stretching only along the length of the board, while bidirectional stretching   The grid is made by continuously stretching the unidirectionally stretched grid in a direction perpendicular to its length.

Because the polymer of the polymer in the geotechnical grid will be rearranged along with the heating and stretching process, the bonding force between the molecular chains is strengthened, and the purpose of increasing its strength is achieved.

玻璃纤维土工格栅 (3) Glass fiber geogrid   Glass fiber geogrid is a network structure material made of glass fiber using a certain weaving process. In order to protect the glass fiber and improve the overall performance, it is a geocomposite material made of a special coating process. The main components of glass fiber are: silicon oxide, which is an inorganic material. Its physical and chemical properties are extremely stable, with high strength, high modulus, high abrasion resistance and excellent cold resistance, no long-term creep; thermal stability Good performance; the mesh structure interlocks and restricts the aggregate; improves the bearing capacity of the asphalt mixture. Because the surface is coated with special modified asphalt, it has dual composite properties, which greatly improves the abrasion resistance and shear capacity of the geogrid.
Sometimes combined with self-adhesive pressure-sensitive adhesive and surface asphalt impregnation treatment, the grid and asphalt pavement are tightly integrated into one. 08 10 ),土工格栅埋入土中的抗拔力,由于格栅与土体间的摩擦咬合力较强而显著增大,因此它是一种很好的加筋材料。 Due to the increase of the interlocking force of the earth and stone in the geogrid grid, the friction coefficient between them increases significantly (up to 08-10 ). The frictional bite force is strong and significantly increased, so it is a very good stiffening material. At the same time, the geogrid is a lightweight and flexible plastic flat mesh, which is easy to cut and connect on site, and can be overlapped and overlapped. The construction is simple and does not require special construction machinery and professional technicians. 可使其具有较好的耐酸、耐碱、耐腐蚀和抗老化等耐久性能。 If anti-aging materials such as carbon black are added to the geogrid, it can have better durability such as acid resistance, alkali resistance, corrosion resistance and aging resistance.
