What is the principle of geogrid?
What is the steel plastic composite geogrid [2]: steel plastic composite geogrid by high strength steel wire by high density polyethylene wrapped into high strength strip, press flat weft at right angles to the welding of geosynthetic materials formed by ultrasonic, according to the needs of the engineering with different mesh diameter and steel wires to change the reinforcement force.
Engineering application of steel plastic composite geogrid: can be used for roads, railways, road construction, embankment and abutment, pier, revetment, levees, dams, beach management, freight yard, slag yard, airport, stadium, green building, soft soil foundation reinforcement, retaining wall, slope protection and pavement anti inferior civil engineering. Features: 1, large strength, small creep, adapt to all kinds of soil environment, can fully meet the use of high grade highway retaining wall. 2, can effectively improve the reinforced bearing surface, occlusal function, interlocking greatly improve foundation bearing capacity, effectively restrain the soil lateral displacement of reinforced foundation, stable performance. 3, compared with the traditional grid has greater strength, strong bearing capacity, corrosion resistance, anti-aging, friction coefficient, perforated uniform, convenient construction, long service life and other characteristics. 4, more suitable for deep sea operations, embankment reinforcement, fundamentally solve the other materials to do a long time due to the erosion of the sea cage caused by low strength, poor corrosion resistance, short service life and other technical problems. 5, can effectively avoid the construction process by machine rolling, damage caused by the construction damage. The principle of Anhui geogrid
GSZ: 1 what are the characteristics of high strength steel wire, steel plastic composite geogrid tension by warp knitting bear, resulting in high tensile modulus at low strain capacity, vertical and horizontal rib synergistic effect, give full play to the role of Geogrid on soil type. 2, steel plastic composite geogrid vertical steel rib weft woven into nets, an outer coating layer forming a steel wire and the outer coating layer can destroy the function of coordination, elongation is very low (less than 3%). The main force unit of steel plastic composite geogrid is steel wire, and the creep is very low. 3, through the production process of plastic surface treatment, suppress the rough pattern, in order to enhance the surface roughness of the grid, improve the steel plastic composite geogrid and soil friction coefficient. 4, steel plastic composite geogrid width of up to 6m, to achieve high efficiency, economic effect of reinforcement. 5, steel plastic composite geogrid used high-density polyethylene can ensure that: at room temperature will not be affected by acid and alkali and salt solution, or oil erosion; will not be dissolved by water or microbial damage. At the same time, the high molecular weight of polyethylene is also sufficient to resist ultraviolet radiation caused by aging. The grille stress aspect rib synergistic effect, can not generate node crack or damage. But in the actual project, after the packing compaction, therefore has not been subjected to the ultraviolet light and the oxygen erosion, therefore completely may satisfy the permanent construction request.
