Polyester grille construction points a construction site: require the compaction flat, horizontal shape, clear spikes projections. 2, the laying of: the formation compaction venue, the installation grille laying the grille its mainly affected by the force direction (vertical) should be perpendicular to the the embankment axis direction, laying to be smooth, wrinkle-free, try tension. Pressure re-nailing and quarrying fixed laying grille is mainly affected by the direction of the force through long connector, the connections between the pieces and the pieces can be manually banding lap, lap width of not less than 10cm. Such as setting the grid in two or more layers between layers should be staggered joint. After the laying of the large area to adjust its overall flatness. Fill cover layer of soil, not compacted again with artificial or machinery tension grille, the intensity should be uniform, the grid in the soil for Bengzhi force status. 3, the choice of filler: filler should design requirements selected. Practice has proved that can be used in addition to freezing soil, swamp soil, garbage, chalk, diatomaceous earth filler. However, the Gravel soil and sandy soil stability, mechanical properties and by the water content has little effect, should be preferred. Filler particle size of not more than 15cm, and pay attention to controlling the the filler gradation, in order to ensure the weight of the compaction. 4, paving and compaction of filler: When the grill after laying positioning should be timely filling covered with the bare time shall timeout 48 may also take the edge laying edge flow process backfilling. In both ends of the paver filler, the grille fixed again Central propulsion. The order of the RCC is first on both sides of the middle. Pressure roller compacted when not directly in contact with the reinforcement, the uncompacted reinforced body generally does not allow the vehicle to be driven in the above, in order to avoid the reinforcement dislocation. The degree of compaction of layered 20-30cm. 5, waterproofing and drainage measures: reinforced soil engineering, we must make the walls inside and outside the drainage treatment; want good foot care, anti-erosion. Features: high tensile strength, tear strength, combined with strong and soil gravel. Warp polyester grille has a very high tensile strength, elongation, corrosion-resistant, anti-aging, and have a stronger bite force base material, quality of light, and a variety of features drainage role. 1, has a very high tensile strength, elongation smaller 3, erosion resistance, aging resistance 4 strong bite force with the base material, quality of light, drainage role Usage: all kinds of high-grade roads, Railway soft subgrade strengthening their base soil material; dam water project, the reinforcement of the river, isolation, and reinforcement of soft soil base and enhance its protection capability to improve the foundation bearing capacity and stability; Road Dibian slope reinforced retaining wall reinforcement, to enhance the overall strength. Application: highway, railway, water conservancy and other soft ground enhanced reinforcement. (A) for a variety of high-grade roads, railways soft roadbed enhance the isolation of different soil base material (b) for riparian embankment slope to strengthen the solid (c) the various consolidating a firm foundation sub (d) for The BRIDGES strengthen warp knitting polyester geogrid polyester warp knitting polyester grille the construction methods grille should shop in the construction of asphalt pavement layer of coarse stone, the original pavement advised flat, finishing, trimming and clean up after be construction, ordinary grill particular the Pinning be fixed grille lap joints transverse greater than 5cm, vertical than 10cm laying asphalt-treated geogrid minimize the spilled asphalt sticky layer of oil, with a self-adhesive geogrid construction after rubber tire compactor moderate RCC, to paving asphalt mixture and compaction, without specific pinning. Polyester warp knitting polyester geogrid made of high strength polyester industrial filament, after the warp knitting orientation woven mesh fabric, PVC coated geogrid processed into. Used in soft soil and subgrade, dams and other projects reinforced enhancements to improve the quality of the project to reduce the project cost. Polyester geogrid purposes: 1, soft soil subgrade rib knitting polyester geogrid for highway, railway, municipal roads and other roads enhanced effectively to improve the strength of the roadbed, slow road reflective cracking. Knitting polyester geogrid water conservancy dam, the reinforcement of the river, isolation, reinforcement of soft soil foundation, enhance its protection capability to improve the foundation bearing capacity and stability. 3 to embankment slope, warp knitting polyester geogrid reinforced retaining walls reinforced, and enhance the overall strength, highway, railway, water conservancy and other soft enhanced reinforcement. 4, warp knitting polyester geogrid for railway ballast protection: Due to the vibration of the train and the wind and rain, resulting in the loss of ballast, live ballast with geogrid wrapped to prevent the loss of ballast to improve the stability of the roadbed; 5 knitting polyester geogrid for Railway retaining wall: geogrid used to the railway edge of the retaining wall enhancement, such as the railway station and cargo station, to extend the service life, reduce maintenance costs; 6, warp knitting polyester geogrid grill for reinforced retaining walls: carrying capacity can improve a retaining wall beside the highway and vertical retaining wall in overlay geogrid; abutment foundation subsidence generally easily down there jumping phenomenon in Abutment Foundation laying of geogrid, can improve the bearing capacity of solid abutments.
