For geosynthetics technology, the country from seepage, filtration, drainage, reinforcement, protection and other aspects of proposed normative technical requirements, greatly accelerated the pace of promotion and application of new materials. The material is widely used in the irrigation canal seepage control project, the combined construction practice of geomembrane application technology. 1, geomembrane performance composite geomembrane (composite impermeable membrane) into a cloth membrane and two cloth one membrane, width 4-6m, weight 200-1500g / square meter, tensile, tear, roof physical and mechanical properties such as breaking high, the product has high strength, good elongation properties, deformation modulus, acid, anti-corrosion, anti-aging, anti-seepage performance characteristics. To meet the water, municipal, construction, transportation, subways, tunnels, construction of impervious, isolation, reinforcement, crack control reinforcement, civil engineering needs. Because of its selection of polymer materials and the production process added anti-aging agent, it can be used in unconventional temperature environment. Commonly used in dams, drainage ditch seepage treatment, pollution prevention and waste treatment field. 2. Construction of composite geomembrane geotextile composite geomembrane is affixed to one or both sides of the film, to form a composite geomembrane. In the form of a cloth membrane, two cloth one film, two films a cloth. As geotextile geomembrane layer of protection, so that impermeable layer of protection from damage. To reduce ultraviolet radiation to increase the anti-aging properties, preferably laying buried in France. Construction, the first to use a smaller diameter material leveling sand or clay base surface, and then laying the geomembrane. Geomembrane not stretched too tightly, buried in the soil at both ends of the body portion is corrugated, and finally in the shop geomembrane layer of about 10cm over layer of fine sand or clay. Lined with 20-30cm stone (or precast concrete blocks) for the anti-scour protection layer. Construction, should try to avoid the stones hit directly on the geomembrane, preferably side to side laying protective layer construction. Geomembrane connection with the surrounding structures should be used to the pressure of the expansion anchor bolts and steel connecting parts to brushing emulsified asphalt (thickness 2mm) adhesive to prevent leakage there. Geomembrane joint processing is a key step directly affect seepage effect. General seams ways are: ① lap: lap width should be greater than 15cm; ② heat welding: suitable for thicker geomembrane base, weld lap width of not less than 5CM (not recommended glued, soaked in water for a long time. easy to open plastic, impervious poor results.) Based on years of proven, geomembranes thickness not less than 0.25mm, too thin may have holes, and easily damaged during construction and reduce seepage effect. Geomembrane construction, laying particular attention to do not too tight, can not fight wrinkles, stitching to secure. In strict accordance with the technical specifications of construction, the good preparation, laying, splicing, testing and backfilling five quality. Due to impermeable geomembrane good effect, at present, water-saving irrigation district reconstruction Baojixia Corollary projects, the extensive use of the material, has been widely praised design, construction units. Geomembrane characteristics: Width 6 meters, is currently the most wide-composite film high resistance to puncture strength, friction coefficient good aging resistance, to adapt to the ambient temperature range suitable for drainage properties excellent resistance to water, chemicals, construction, transportation, subway engineering applications, tunnels, waste disposal sites, etc.: 1. Environmental protection, sanitation (such as landfills, sewage treatment plants, power plants regulation pool, industrial, hospital solid waste, etc.). 2. WATER RESOURCES (such as rivers, lakes and reservoirs dam seepage, sealing, reinforcement, drainage of seepage, vertical heart wall, slope protection, etc.). 3. Municipal Engineering (subway underground engineering, building, green roofs, seepage, sewage pipe lining roof garden, etc.). 4. Garden (artificial lakes, rivers, reservoirs, golf course pond underlay, slope protection, afforestation lawn waterproof moisture, etc.). 5. Sinopec (chemical plants, refineries, gas stations tank seepage, chemical reaction tank, sedimentation tank lining and secondary lining, etc.). 6. Mining (washing pools, heap leaching pool, the ash field, dissolving tanks, sedimentation tanks, yard, backing tailings seepage, etc.). 7. Transport facilities (road base reinforcement, culverts impermeable). 8. Agriculture (reservoirs, water tanks, water storage pond, irrigation systems seepage). 9. Aquaculture (intensive, factory farming pond, fish ponds, shrimp ponds lining, Ouchi, sea cucumber circle slope protection, etc.). 10. Salt (salt crystal pool, brine pool thatch cover, salt film, Salt plastic thatch film).
