Uniaxial geogrid is a kind of polymer as the main raw material, adding some UV protection, anti-aging additives, through one-way stretch so that the original distribution of the chain-shaped molecules scattered linear re-aligned state, by extrusion pressed into sheets and then washed rules mesh, then vertical stretching high strength geotextile material. This process, polymer and formed into a linear state directional distribution, node strength oblong mesh overall structure. This structure has a very high tensile strength and tensile modulus, tensile strength reached 100-200Mpa, close to the level of low-carbon steel, much better than the traditional or existing reinforced materials, especially the company of such More products with ultra high international level of early (elongation at 2% -5%) tensile strength and tensile modulus. Soil provides the ideal force commitment and the proliferation of chains. The product tensile strength (> 150Mpa), to adapt to a variety of soil, is currently widely used in reinforced reinforcement. Unigeogrid purposes: one-way geogrid, one-way geogrid reinforcement of soft ground: geogrid can rapidly improve the bearing capacity, settlement control the development of side effects limit road base can effectively to the load distribution to the wider sub-base, thus reducing the base thickness, reducing construction costs, shorten the construction period and prolong life. 2, one-way geogrid reinforced asphalt or concrete pavement: geogrid laid on asphalt or concrete overlay on the bottom, can reduce rut depth, extend the pavement fatigue life, but also can reduce the thickness of asphalt or concrete pavement in order to save costs. 3, one-way road geogrid reinforced embankment slopes and retaining walls Buddha: the traditional embankment filling, especially the high embankment and shoulder often require ultra-edge easily compacted fill, causing flooding in the late slope of the rain hit, collapse When instability phenomena occur at the same time need to use more moderate slope, large area, retaining walls have the same problem, the use of geogrid reinforced embankment slopes or retaining walls can reduce the area of ??half a area, long life, low cost of 20-50%. 4, one-way geogrid reinforced river dikes: gabion can be made, then the grid and used to prevent dam collapse caused by the sea erosion, gabion permeable, can slow the impact of the waves, to extend the life of the dam, save human and material resources, shorten the construction period. 5, one-way geogrid used to process landfill: geogrid synthetic materials combined with other land use process landfill, can effectively solve the uneven settlement of foundation, derived gas emissions and other issues, and maximize landfill storage capacity. 6-way special purpose geogrid: resistance to low temperature resistance. Friendship's resistance to low temperature geogrid at -45 ℃ --- 50 ℃ repeated thermal cycling 200 times, the performance indicators are to meet the requirements, and the Qinghai-Tibet Railway has been tested for a few frozen northern soil, rich frozen soil, high ice content permafrost adverse geology.
