To study investigated the geomembrane, especially the larger aperture woven fabrics for protection engineering, natural waves, currents, tides role in the anti-scouring brush case, select the project to be applied geomembrane several non-woven fabric (non-woven) and woven fabric (Table 5] 2. Pat, E6 two kinds woven), respectively, in the Liaohe River revetment construction site, Xingcheng long Temple Bay Seawall and Dawa River embankment embankment conducted a field test of scour. Test methods; the land is protected weighed into the 1. oM: 1.0m x o. 1M wooden box inside, according to a certain density compaction, covering geomembrane above and fixed to the wooden frame, sub-capping layer (concrete board, etc.) and not stamped on geotextile geomembrane layer in both cases, then the wood box set on the shore or Dipo withstand water, waves scour through the "fixed time, remove the wooden box called a comeback. By measuring before and after the water content, particle analysis, protected soil erosion around the dry soil weight and particle and so changes in the composition analysis, it can be seen from Table 5-10, soil erosion after heavy erosion substantially greater than before, not decreased, but increased from the point of view of soil particles, after scouring powder, grain teach something increased analysis of the reasons is the geomembrane 7L soil particle size diameter greater than when the shock waves of water or cloth, it is possible to Ken river water, sediment punch people box, because geomembrane river sediment concentration test 3.o-6.okdm3, the median diameter was o. Tsukuda .o.026M. This shows that the larger river sediment concentration, geomembrane larger aperture does not cause scouring brush protected territories, may use oM thing todD design specifications. (1) Beijing Dongbeiwang farm on the south main canal buried under the soil to protect Chan M Edison plastic film impermeable geomembrane, geomembrane run after 20 years, the sample testing, strength not decreased, but increased slightly Geomembrane wholesale, just an extension of Lee lowered too large, impermeable plastic film still maintain good performance. Longhai County in Fujian Province, buried in the hillside levee thickness o.3 * o.04M impermeable plastic film impermeable geomembrane, with six years after sampling check its strength decreases 2t.7%, elongation is reduced by 26.4%, this calculation plastic film may be at least 20 years of use. (2) Shanxi Bei Region impermeable plastic film channels apply more than 20 years of experience, 13 years after sampling operation is determined according to the plastic film is reduced by about 30 percent anti-tensile strength, elongation is reduced by 37.5% Geomembrane manufacturers, but Flexible still good and, consequently, impermeable plastic film, such as the absence of external disturbances, the material can work 30.40 years. (3) The United States Bureau of Reclamation to run for seven years for PVC film channel seepage conduct a detailed observation to check in there is 23cm thick gravel province, under a protective layer of soil material sampled stones with a diameter of 2.5-5M breakdown test as pressure, water pressure when it geomembrane damage reduced from the initial value 352kN 282kPa, declined by about 20 percent. It follows that the film can be used at least 30 years. Qingyang Edison Group _ _ Geomembrane Geomembrane professional provided by New Materials Co., Edison.
