One-way stretch plastic geogrid products introduced one-way stretch geogrid is pressed into extruded polymer sheet and then washed rules mesh, and vertical stretching. 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, especially my company such products more super 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. Product Features 1. Enhance roadbed, which can effectively spread of load distribution, improve the stability and foundation bearing capacity and prolong life; 2. Can withstand greater alternating load; 3. Prevent roadbed subgrade material loss caused by the deformation and cracking ; 4. Make the filling after self-supporting capacity of retaining walls to improve and reduce the pressure on the retaining wall of earth, to save costs, extend the life and reduce maintenance costs; 5. concrete construction methods combined with spray anchor Slope maintenance, not only Save 30% -50% of the investment, and can shorten the construction period more than doubled; 6. Add geogrid in the roadbed and road surface, you can reduce the deflection and reduce rutting, cracks appear delayed time 3-9 times, structural layer thickness can be reduced by 36%; 7 for a variety of soil, no remote drawn, when saving time and labor; 8. Construction is simple and efficient, can greatly reduce the construction costs. Usage Uniaxial geogrid is a high strength geosynthetics. Widely used in dams, tunnels, ports, roads, railways, buildings and so on. Product specifications and performance parameters of product features a unidirectional high tensile strength, good creep resistance, chemical stability; 2, friction coefficient and gravel. Applications 1, mainly used for retaining walls, abutments, steep slope engineering; 2, retaining walls and abutments are the force structure, to assume all external loads: active earth pressure, the upper part of the structure of the dynamic load, temperature stress etc., reinforced materials under long-term repeated the role in the larger tension, and dynamic load, the molecular structure of the material fatigue, which occurs attenuation performance, accelerated aging grid. To avoid structural reinforced materials due to creep deformation and greater, you should choose a high-density polyethylene (HDPE) as raw material unigeogrid. ○ When used in roadbed construction methods, when road construction methods with the same two-way geogrid. ○ When used in reinforced earth retaining wall, the construction method is as follows: 1, set the foundation, according to the design of the wall system construction, when elected to the use of precast reinforced concrete panels, generally supported 12-15㎝ thick precast concrete foundation. Its width is not more than 30 cm, thickness not less than 20 cm, depth of not less than 60㎝ prevent heaving affected. 2, flat base of the wall, according to design requirements excavation, leveling. Soft soil compaction or change need to fill, compacted to the required density, should be slightly beyond the scope of the wall. 3, laying reinforcement, reinforcement should be perpendicular to the direction of the main strength of the wall to pin fixed. 4, filling the wall, using mechanical filling, the distance between the wheels and the reinforcement should be kept at least 15 cm. 20-15㎝ thick layer of soil compaction. 5, when the construction of the wall, the wall of the bag should geotextile to prevent leakage of fill
