2, to highlight the advantages of geogrid is deformation under sustained loading (creep) tendency is very small, creep strength is much better than other materials geogrid, plays an important role in improving the service life of the project;3, the mesh grille and soil interlock and interlock function, constitute an efficient stress transfer mechanism, so that local load can be quickly and effectively spread to a large area of soil, to reduce the local failure stress, improve the service life of engineering.
First, the characteristics of uniaxial tensile plastic geogrid:1, the polymer into a linear state and the formation of a uniform distribution, high strength of the node of the long elliptical mesh integral structure. This kind of structure has high tensile strength and rigidity, and it provides the ideal chain system of bearing and diffusion of soil;
GDL geogrid is uniaxial plastic geogrid, uniaxial plastic geogrid with high density polyethylene (HDPE) as raw materials, pressure into a sheet by extrusion and punching network rules, and then the longitudinal stretch into the geogrid.
