An arrangement, strength, creep, and adapt to various environmental soil, and fully meet the tall retaining wall in the high-grade highways. 
 Steel-plastic geotextile grille 

 Steel plastic geogrid, a high-strength steel (or other fiber), specially treated polyethylene (PE) or polypropylene (PP), and add other additives, extrusion making composite high strength tensile strip , and the surface rough embossed, compared with high-strength reinforced geotextile with. This single band by the longitudinal cross a certain pitch preparation or clip together using a special strengthening adhesive welding technology welding to its intersection molding is reinforced geogrid. 
 Product features: 
 A strength, the deformation is small; 
 (2) creep is small; 
 Corrosion-resistant, long life: steel plastic geogrid plastic materials for the protective layer, supplemented with various additives to the harsh environment of the aging, oxidation, acid, alkali, salt corrosion. Therefore, the steel-plastic geogrid to meet the needs of all types of permanent works of more than 100 years, and the excellent performance, good dimensional stability. 
 Construction convenient, short cycle, low cost: steel plastic geogrid laid lap, positioning easy, flat, to avoid overlapping cross, which can effectively shorten the project cycle, saving 10% -50% of the project cost. 
 Engineering applications: 
 Highways, railways, bridges, approach roads, docks, dams, slag fields of soft soil reinforcement, retaining walls and pavement crack engineering and other fields. 
 Project role: 

 2, can effectively improve the interlocking of the reinforced bearing surface, occlusal function, greatly enhanced foundation bearing capacity, lateral displacement of the effective binding soil, enhance the foundation of a solid performance. 
 3, compared with the traditional grille, more strength, bearing capacity, anti-corrosion, anti-aging, friction coefficient, the holes evenly, easy construction, long life. 
 More adapted to deep-sea fishing, embankment reinforcement, a fundamental solution to the other materials do gabion long-term erosion by sea, low strength and poor corrosion resistance, short life technical problems. 
 5, can effectively avoid the construction process equipment crushing, damage caused by construction damage. 


 Construction method of steel-plastic geogrid 
 Laying geogrid surface should be relatively flat ply their acceptance, to prevent the vertical skew phenomenon, press width of ply draw a white line or hung, you can start laying, and then use the U-shaped nails the end of the fixed grid (meters wide with nail 4, even a fixed distance); 
 2, end of fixed grille, the grille will use pavers or artificial means slowly pull forward Shop, Shop 10 m long manual survey once, until the roll grille Puwan, holes and under the roll. before operating the same; 
 3, then shop: roll length as the laying of a long paragraph, shall be paved with grill covered section chief, and then the whole check in laying quality, and then followed by the laying of the next paragraph, the next period of laying, grill grid gate overlapping a grid spacing for the length of lap, and with binding wire fixed to continue to shop the second paragraph in the forward direction. And so on, the operational requirements with the former.
