According to Dawa and the Hun River embankment slope soil test results, Cheung indoor filtration analysis drawn by A. Curve shown in Figure. According to the different experimental conditions mutated geomembrane Richard critical curve points (destruction) gradient table. Composite geotextile where the production from the test results analysis, selected a good anti-clogging performance geotextiles, especially the Dawa soil. Whether in standard or non-standard tests Huai best composite geotextile, Dawa soil Cheung cR values ??are less than o. 8, Andrew Dawa standard soil test, Alexandra value even less than o. 5. Substantially equal to o. 44. Only the largest case of non-standard o. 76, but with the increase in head even decreased, indicating the role of head of the higher filtration geomembrane play better. Hun River soil samples were used geomembrane filtration effects, although not as good at Dawa soil samples, but also within the range allowed by the specification (cA'3), is also the head of the higher, the better the filtration effect play. That is woven with a larger pore size is very small, as the likelihood of clogging of the filter layer. As can be seen from the figure the geomembrane, in the case where the hydraulic gradient is less than 73, the permeability coefficient and flow velocity are not mutated, flow rate and water head under various conditions geomembrane substantially maintained a relatively slow proportional growth of eels. Critical protective case (the damage) was significantly higher than those without the protection of slope, in line with the actual project situation. There are two conditions under the protection of r. Point mutations i f curve is greater than 95, the protection of gravel i value greater than 100, which is equivalent to a 95- 100m head in 1M thick filter layer seepage path. Geomembrane revetment works on flood control is almost impossible, in fact, it is sufficient to meet the project by 50 security needs. So geomembrane show by experimental analysis of indoor filtration geotextile om poison 10J9 Soil new guidelines for insurance protection engineering filtration designed with adequate margin of safety. Filament geotextile retaining, water, liquid storage structures such as anti-brown i building roof, underground engineering seepage; waste and tailings leachate pollution and roadbed watertight, filament geotextile seepage and other projects can be geosynthetics. Geosynthetics for seepage can choose geomembrane, stage fabric GCL (GcL) and composite waterproof material. Elevation, size, scope, seismic requirements set seepage facilities as well as other parts of the slope of the connections or filament geotextile must meet the design requirements of the main project. The main project using geosynthetics seepage are: (1) dam, Victoria dam, masonry dam and roller compacted concrete dam (2) embankment, dam levels impervious blanket, ground vertical impermeable layer (3) End mine dam, water reservoir dam and reservoir area. (4) cofferdam o (5) channels, storage shed pool (pit, pond). (6) the scrap yard. (7) Subway, basements and tunnels, tunnel impermeable lining. (8) the roadbed. (9) fed salt roadbed and other foundation of prevention. (10) waterproof layer of expansive soil and wet recessive loess. (11) roofing seepage. Anti-red, anti-wave, frost, shock, fixing, prevent salt and anti-evolution composite geotextile landslides and other protective measures how much a square meter of cloth, filament geotextile can be used geosynthetics or products. Used for protection - dead workers synthetic materials can be used geotextile, geomembrane, geogrid, soil: 2 nets, geotextile bags, Geocell, geotextile mat and polystyrene plates and so on. For protection with geosynthetics products can geotextile bags and soft mattress and other t, geotextile bags should be included sand, sand pillows, pillow soil, soil bags. Soft mattress should be woven geotextiles combined ballast made filament geotextile monolithic software can be divided into rows and rows of two-piece soft composite geotextile fabric how much a square meter, sunshine composite geotextile, new materials by Edison Edison New Materials Co., Ltd. offers.
