Tricot polyester geogrid selection of high-strength synthetic fiber as raw material, the use of directional structure warp the fabric of the warp and weft yarns between each other without bending state, the intersection with the high-strength fiber filament bundles combine to form a solid combination of points, fully play its mechanical properties. High-performance warp strength polyester geogrid is untwisted filament as raw material, the use of warp warp weft insertion technology to produce a grid-like fabric. Its latitude and longitude between each other without bending state yarns, at the intersection of high-strength polyester filament bundles through to form a solid combination of points, it can give full play to its mechanical properties, with high tensile strength, low elongation, tear strength, small differences in latitude and longitude to strength, resistance to UV aging, wear resistance, corrosion resistance, light weight, and with a strong soil or gravel embedded in the lock, etc., can significantly enhance the shear resistance of the soil to improve soil integrity and load capacity. Thus, the grid is widely used in water conservancy, road construction and other projects, and achieved remarkable economic and social benefits. Polyester geogrid Features: 1, with a high tensile strength; 2, elongation is small; 3, anti-corrosion, anti-aging; 4, with the base material has a strong bite force; 5, light weight, drainage Role polyester geogrid use: various roads of soft soil subgrade reinforced a highway, railway, municipal roads and other enhancements, can effectively improve the strength of subgrade, delaying reflection cracks in the road. 2, Water Project dams, channel reinforced, isolation, reinforcement of soft soil foundation, to enhance its defense capabilities, improve the bearing capacity and stability. 3, for embankment reinforcement, retaining wall reinforcement, enhance the overall strength, roads, railways, water and other soft enhanced reinforcement. 4, for railroad ballast protection: As the train vibration and wind and rain, resulting in the loss of ballast, with geogrid wrapped ballast to prevent the loss of ballast, improve the stability of the roadbed; 5 for railway retaining wall: geogrid reinforced retaining wall on the edge of the railway, for example, in the railway station and dock with the station, prolong life, reduce maintenance costs; 6 for reinforced retaining wall: plus vertical retaining wall next to the road and the Geogrid, can increase the carrying capacity of retaining wall; 7, abutment foundation subsidence generally very easy to down, jumping phenomenon occurs, laying geogrid at abutment foundations, can improve the bearing capacity, stable abutment.
