Polyester warp polyester geogrid warp polyester geogrid TGS20-20KN, TGS-30-30, BJG50-50 BJG60-60 TGS-80-80, TGS-100-100 width of 4-6 meters polyester grid various road soft soil subgrade reinforcement Applications 1, for road, railway, municipal roads and other enhancements, can effectively improve the strength of subgrade, delaying reflection cracks in the road. 2, Water Project dams, channel reinforced, isolation, reinforcement of soft soil foundation, to enhance its defense capabilities, improve the bearing capacity and stability. 3, for embankment reinforcement, retaining wall reinforcement, enhance the overall strength, roads, railways, water and other soft enhanced reinforcement. 4 for railway ballast protection: As the train vibration and wind and rain, resulting in the loss of ballast with geogrid wrapped ballast to prevent the loss of ballast to improve stability of the roadbed; 5 for railway retaining wall: geogrid reinforced retaining wall edge of the railway, for example, in the railway station and dock with the station, prolong life, reduce maintenance costs; 6 for reinforced retaining wall: add in next to the highway and vertical retaining wall Geogrid, can increase the carrying capacity of retaining wall; 7, abutments ground subsidence is generally very easy to down, jumping phenomenon occurs, laying geogrid in bridge abutment foundation, can improve the bearing capacity, stable abutment. Features polyester grille 1, 2 has a very high tensile strength, elongation 3, corrosion resistance, anti-aging 4, and the base material has a strong bite force 5, light weight, there is drainage polyester grille Construction Technology and Points 1, the construction site: Requires compaction level, is horizontal, clear spikes projections. 2, grid lay: on flat compacted site, installing laying grille its main force direction (vertical) axis should be perpendicular to the direction of the embankment, laying should be smooth, without wrinkles, the tension as much as possible. Ballast fixing nailing and quarrying, laying grille main direction of the force is the best long pass no joints, connecting web between the web can be manually banding lap, lap width of not less than 10cm. Such as setting the grid in two or more joints should be staggered between layers. After laying a large area, to adjust its overall flatness. When filling covered with a layer of soil, not before rolling should again tensioned by manual or machinery grille, the intensity should be uniform, so that the grille in the soil as Bengzhi stress state. 3, the choice of filler: filler design requirements should be selected. Practice has proved that, in addition to frozen soil, swamp soil, garbage, chalk, diatomaceous earth can be used as filler outside. But of gravel soil and sandy soil mechanics stable performance, by the water content has little effect, should be preferred. Particle size no larger than 15cm, and pay attention to controlling the filler size distribution, in order to ensure compaction weight. 4, packing paving and compaction: When laying the grill positioning should promptly fill Covered, Uncovered time shall timeout 48 that can take side laying backfill side of assembly-line method. First at both ends paving filler, grill fixed, again the central forward. Laminated on both sides after the first order is intermediate. When the pressure roller is not in direct contact with the compacted reinforcement, not compacted reinforcement generally not allowed to travel on top of the vehicle, in order to avoid dislocation of reinforcement. Stratified degree of compaction 20-30cm. Compactness must meet the design requirements, and this is the key to success reinforced soil engineering. 5, waterproof and drainage measures: the reinforced earth works, drainage treatment must make internal and external wall; to do foot care, anti-erosion; the body to be set in the soil filter, drainage measures, if necessary, should be set geotextiles , through landfill waste disposal generally be divided into sanitary landfill, incineration and power generation in several ways.
