Steel geogrid is a novel high-strength geosynthetics, made of special treated steel wire of high strength with polymeric material composed. It is mainly used in the civil engineering such as highway, railway, embankment, dock, dam, airport, stadium, soft soil reinforcement, retaining wall and slope protection.
Characteristics
1. Large strength, small creep deformation, be suitable for a variety of environmental lands and can satisfy the design requirements in the high-grade road absolutely.
2. Improve the interlocking and occlusion of the loading surface with ribs added in, strength the loading capacity of road base extremely, restrict the lateral displacement of the land effectively, reinforce the stability of the ground work.
3. Compared with the traditional geogrid, it owns the advantages of larger strength, stronger loading capacity, anti-corrosion, ageing resistance, large frictional coefficient, average eyelet, convenient to construct, long service life.
4. It is more applied to the deep sea work, embankment reinforcement and solve the difficult technical problem in aspect of low strength, bad anti-corrosion, short service time caused by the sea water attacking and corroding by using the other materials as stone cage.
5. It can effectively avoid constructional damage caused by rolling and breaking in the construction.
6. Provide a more excellent advantage of a width of 6 meters for the design and construction. Increase the sales and cut down the cost.
