Ⅰ.Product Introduction
The steel-plastic composite geogrid is made of high-strength steel wire (or other fiber). The high-strength steel wire is specially treated with polyethylene (PE) and other additives, that is, they are extruded into a composite high-strength tensile strip with rough embossing surface, namely a high-strength reinforced geobelt. The single belts are established according to a certain distance in the longitudinal or transverse direction or arranged by clamping, and then they are welded by a fusion welding technique with capacity of special strengthening bonding to form a reinforced geogrid.
Ⅱ.Technical Characteristics of the Product
1. The steel-plastic composite geogrid has the characteristics of high strength and small deformation.
2. The steel-plastic composite geogrid has the characteristics of small creep.
3, The steel-plastic composite geogrid resists corrosion, and has a long life. The steel-plastic geogrid is made of plastic material as a protective layer, supplemented by various additives to make it endure age, resist oxidation and corrosion in harsh environments such as acid, alkali and salt. Therefore, the steel-plastic geogrid can meet the needs of various permanent projects for more than 100 years, and has excellent performance and good dimensional stability.
4. The steel-plastic composite geogrid has the characteristics of convenient construction, short construction cycle and low cost. The laying, lap jointing and positioning of the steel-plastic geogrid are easy and the laying is smooth. So it can avoid overlap and crossover, which can effectively shorten the construction cycle and save 10%-50% of the project cost.
Ⅲ.Engineering Application
The soft soil foundation reinforcement, and anti-cracking projects of retaining walls and pavement in the field of roads, railways, bridge abutment, approach roads, docks, revetments, dams, slag yards, etc.
