What’s Steel Plastic Composite Geogrid?
Lianyi®Steel-plastic composite geogrid is a geosynthetic material made by wrapping high-strength steel wires with high-density polyethylene to form high-strength strips, which are arranged at right angles in the plane longitude and weft, and then welded by ultrasonic waves. According to the engineering requirements, the tensile force of the strips can be changed by using different mesh diameters and the number of steel wires. High-strength steel wires (or other fibers) are specially treated and combined with polyethylene (PE) or polypropylene (PP) And by adding other additives and through extrusion, it becomes a composite high-strength tensile strip. If the surface has a rough texture, it is a high-strength reinforced geotextile strip.From this single strip, it is woven or interlaced at certain intervals in the longitudinal and transverse directions, and the junction points are welded by a special reinforced bonding fusion welding technology to form a reinforced geogrid.
Features Of Steel Plastic Composite Geogrid
*High strength and small deformation
*Small creep
*Corrosion resistance and long service life: Steel-plastic composite geogrid are protected by plastic materials and supplemented with various additives to endow them with anti-aging and oxidation properties, enabling them to resist corrosion in harsh environments such as acids, alkalis, and salts. Therefore, steel-plastic composite geogrid can meet the usage requirements of various permanent projects for over 100 years, and they have excellent performance and good dimensional stability.
*Convenient and fast construction, short cycle and low cost: Steel-plastic composite geogrid is easy to lay, overlap and position, and are smooth, avoiding overlapping and crossing. This can effectively shorten the project cycle and save 10% to 50% of the project cost.
Applications Of Steel Plastic Composite Geogrid
*It features high strength, low creep, and adaptability to various soil environments, fully meeting the requirements for high retaining walls in high-grade highways.
*It can effectively enhance the interlocking and biting effect of the reinforced bearing surface, greatly increase the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and improve the stability of the foundation.
*Compared with traditional geogrid, it features greater strength, stronger load-bearing capacity, corrosion resistance, anti-aging, large friction coefficient, uniform holes, convenient construction and long service life.
*It is more suitable for deep-sea operations and embankment reinforcement, fundamentally solving the technical problems such as low strength, poor corrosion resistance and short service life caused by long-term erosion by seawater when other materials are used to make gabions.
*It can effectively prevent construction damage caused by being crushed or damaged by machinery during the construction process.
