Bi-Oriented Geogrid Extruding LineBi-Oriented Geogrid Extruding Line The bi-directional geotechnical grille are made of PP and HDPE , and processed by special pressing and bi-directional stretching . Can decrease the required structural filling soil, arrange the even load distribution ,has quite higher bi-directional stretch modulus and stretch strength, quite high mechanical damage resistant strength and durability . And is mainly is applied in soft base treatment and string-enforced structure. Dig the base ,set the sand layer(height difference not more than 10cm),roil into the platform,lay the grille,the longitudinal shaft shoula in the direction with the main force direction,the longitudinal lap for15-20cm,and sidelong for 10cm,the lap should be tied by plastic belt ,and fix with U-nail every 1.5-20m,and the grille should be backfilled with soil on time ,and the layers are determined by the technical rrquirements Bi-directional stretch pp geotechnical grille property data sheet Property Unit TGDG15-15 TGDG20-20 TGDG30-30 TGDG40-40 TGDG45-45 Unidirectional ared weight g/m2 300±50 330±50 400±50 500±50 550±50 Roll width m 4.0±0.20 Longitudinal stretch strength per meter KN/m 15 20 30 40 45 Sidelong stretch strength per meter KN/m 15 20 30 40 45 Longitudinal yielding extension ratio % 13 Sidelong yielding extension ratio % 16 Stretch strength on2% longitudinal extension ratio KN/m 5 8 11 13 16 Stretch strength on 2% sidelong extension ratio KN/m 7 10 13 15 20 Stretch strength on5% longitudinal extension ratio KN/m 8 10 15 16 25 Stretch strength on 5% sidelong extension ratio KN/m 10 13 15 20 22 MAIN TECHINCAL DATA EQUIPMENT MODEL EXTRUDER ASSEMBLED WIDTH OF FINISHED PRODUCT LINEAT SPEED OUTPUT(m2/n) FNC130 Φ150/33 4000 0-4 600 FNC140 Φ160/33 5000 0-4 700 FNC160 Φ160/33 6000 0-4 750
