Geomembrane, HDPE geomembrane, LDPE geomembrane geomembrane and so are the more representative species. As impermeable material with excellent performance, geomembrane having a corrosion resistance, low temperature, frost performance is good and so on edge, especially in the promotion of overburden pressure channel geomembrane seepage control and use is commendable. Geomembrane is reinforced modified polyethylene or PVC, calender film forming and polyester geotextile heat is made with a tensile strength, bursting resistance, high tear strength, elongation properties, deformation modulus, anti-aging, anti-seepage performance, use a long period and so on. After it is combined with plastic film, not only increases the tensile strength and puncture resistance of the plastic film, and because of non-woven surface roughness and increase the contact surface of the friction coefficient, is conducive to protective layer of geomembrane and geotextile stable Due to these characteristics the film short silk geotextile, in Canal Seepage Control Treatment promote the adoption of Edison staple fiber geotextiles, and achieved good economic and social benefits. Combined with a number of construction cases irrigation water saving project Corollary geomembrane. The establishment of a film based on the traditional theory of the surrounding geomembrane stress analysis model deformation under circular structures lying under the soil subsidence was found lying under the soil subsidence in the next round in the structures surrounding the geomembrane wrinkles and reveals its produce Mechanism. Further by introducing a 'variable Poisson's ratio' concept and the establishment of a fold region and geomembrane deformation stress analysis model based on the tension zone folds film theory, the size of underlying soil settlement, the overburden pressure, geomembrane interface strength . These are related to geomembrane small series to introduce you to the promotion and application of the overburden pressure channel seepage control, in fact, no matter what the field is used, geomembrane role can be played to the maximum extent. Within the range of the first: the process first week dam geomembrane taken while digging, side shop, while tamping, while retaining the zone circulating jobs. Second: the base surface cleaning base surface must be in accordance with design requirements cleaned up, which is critical to ensure that anti-seepage effect, especially on sharp stones, roots and other debris to be thoroughly cleaned, the base surface does not allow partial bump phenomenon, Cleanup good base to use tamper plate tamper rammer or tight, dense and smooth to make. Third: geomembrane laying laying, must while laying the upper and lower. Between the film and the film and the film and the substrate surface to flatten snapping, but not the film is pulled too tight, usually slightly loose a little, but you can not leave bubbles in the film at the end. Because geomembrane relatively thin and very light, later paved, paved the protective layer without previous short silk geotextile customized easily by the wind, so the area should not be a laying of large, preferably while laying side cover protection layer of soil material. Provide information, according to the manufacturer of composite geomembrane width 1.0 ~ 1.9m, 1.9m width of the projects selected to reduce the joint use of materials. Fitting hot sticky, adhesive, lap and other methods, the project design uses adhesive seam width 50mm. If it is found geomembrane puncture or tear the place, be sure to use three times the area of ??subsidies damaged geomembrane good adhesive. The protective layer and surface protection, by 10cm thick protective layer of geomembrane material must be sieved soil, does not allow more than the particle size greater than 6mm, or easily punctured geomembrane. The protective layer of soil material must use the pounding dense, dry bulk density of 1.5 or more to ensure short silk geotextile manufacturers, and sampling and testing at any time. The protective layer and backfill stone masonry surface protection, must be light, so as not crashed geomembrane. Try no welds.
