bx-geogrid and other new geogrid ,we have the patent, welcome to contact us.
Geogrids represent a rapidly growing segment within geosynthetics. Rather than being a woven, nonwoven or knitted textile fabric, geogrids are polymers formed into a very open, gridlike configuration, i.e., they have large apertures between individual ribs in the machine and cross machine directions. Geogrids are (a) either stretched in one or two directions for improved physical properties, (b) made on weaving or knitting machinery by standard textile manufacturing methods, or (c) by bonding rods or straps together. There are many specific application areas, however, they function almost exclusively as reinforcement materials.
Stiff polymer geogrids are used in layers with mineral aggregate fills or other suitable soil to create a stiff mechanically stabilised layer within the soil and thus improve its load bearing capacity. The apertures of the grid hold or confine the aggregate or soil particles, preventing the lateral shear created by vertical loading.
The latest developments in stiff polymer geogrid manufacture are based on an isosceles triangular aperture, produced by a new manufacturing technique from a punched then stretched polymer sheet. Whereas uniaxial and biaxial geogrids offered maximum in-plane stiffness in one and two axis, respectively, the triangular aperture results is a near isotropic in-plane stiffness.
