Macromolecule extrusion vigor less chemical character, longitudinal stretching products; stretching procedure entirety and distributed uniform oval structure; strong intensity and physical strength of stretching direction.The structure can supply ideal linking system. It has strong stretching ability (>150MPa), suitable for various kinds of land soil. It is an ideal stretching material prior to non-stretching geosynthetic net. Applications: 1) It is a high-strength structure material, suitable for strengthening highway, road, railway, and airplane lane. Strengthen road base, can effecting distribute loading; improve stability, loading capacity and usage validity of road base. Prevent material of road base from flowing away and deforming, breaking road base. Bear much more loading capacity. Suitable for various kinds of land soil, saving labor and time construction simple and quick. 2) Suitable for strengthening land-blocking wall of sea and rivers side. Improve loading capacity of land blocking wall. Shorten 1/2 covering land measure of area, extend usage validity reduce maintaining charges. 3) Suitable for strengthening dams and dikes of river. Making stone cage together with grille, prevent dams and dikes from scouring, sinking. Stone cage is permeability, can retard sea waves to attack, improve life of dams and dikes, stone cage can save large-quantity material, labor, shorten construction time. Suitable for protecting fence of orchard, vegetable land, livestock, construction site, convenient and quickly installing, unloading. Good appearance, clear at glance.border=0>;
