Physical characteristics of geogrid construction method
One way tensile geogrid1, is a kind of polymer as the main raw material, adding anti UV, anti aging agent must, after the original tensile distribution chain shaped molecules scattered re aligned linear, pressure into a sheet by extrusion and punching network rules, high strength geosynthetics and longitudinal stretch into the. In this process, the polymer is in a directional linear state and a long elliptical structure with uniform distribution and high node strength is formed. This structure has very high tensile strength and tensile modulus, tensile strength reached 100-200Mpa, close to the level of low carbon steel, much better than the conventional or existing reinforced materials, especially in the company of such products is more than the international level of the early high (elongation at 2% - 5%) tensile strength and tensile modulus. A chain system that provides an ideal force for the soil to bear and spread. The tensile strength of the product (>150Mpa), to adapt to a variety of soil, is widely used in the reinforcement material. Unidirectional geogrid use:Unidirectional geogrid, 1 unidirectional Geogrid Reinforced Soft Foundation: Geogrid can rapidly improve the bearing capacity of the foundation and development of settlement control, can effectively load to the base of a wider upper limit on the road side, thereby reducing the base thickness, reduce project cost, shorten the construction period, prolong the service life.
1, with a strong tensile strength, tensile strength in the range of 25-110kn/m, according to the product model is not the same, tensile strength is not the same.2, the stress elongation is small, the structure has a good lateral stability and enhance the ability.3, high physical and chemical stability, anti-aging, anti soil burial, good corrosion resistance.4, the friction coefficient is large, the net structure is fully integrated into the earth and rock structure to enhance the stability of the structure.5, the resistance to environmental stress is strong, when the stress is enhanced with a small amount of deformation, in the -20 to 120 degrees centigrade range of temperature deformation coefficient is small.6, the width of the general 4 -6 meters, light installation construction is simple and convenient, efficient, economic.
2, check the geogrid reinforced asphalt pavement or cement: Geogrid laying layer at the bottom of asphalt or cement, can reduce rutting depth, prolong the fatigue life of the pavement, but also can reduce the asphalt or cement pavement thickness, in order to save costs.3, one-way geogrid for reinforcing the dam and road slope and retaining wall: the traditional embankment especially filling high embankment filling and often need to shoulder edge easy compaction, resulting in slope rainwater invasion, collapse phenomenon, at the same time with a gentle slope, covers an area of large, retaining wall have the same problem with Geogrid embankment slope or retaining wall reinforcement can be reduced by two points a area, prolong service life, reduce the cost of 20 - 50%.4, one-way geogrid to reinforce the River seawall: made of stone cage, with the grid and use, prevent the dam washed collapse, stone cage is permeable and can reduce the impact of the waves, prolong the life of the dam, save manpower, shorten the construction period.5, one-way geogrid for processing landfills: Geogrid and other synthetic materials using a combination of Soil Treatment Landfill, can effectively solve the problem of gas emissions derived from the uneven settlement of foundation, and can improve the landfill to maximize storage capacity.6, one-way geogrid special purpose: low temperature resistance. Low temperature resistance of geogrid Lianyi, at - 45 C and 50 C - repeated 200 cycles, the performance indexes meet the requirements, and has been applied to the test of the Qinghai Tibet railway, the North less ice permafrost and ice rich permafrost and ice rich permafrost bad geology.
