Geomembrane, HDPE geomembrane, LDPE geomembrane geomembrane and so are the more representative species. As impervious material with excellent performance, geomembrane Geomembrane has a corrosion resistance, low temperature, good frost resistance and so on edge, especially in the overburden pressure geomembrane promotion channel seepage control and adopt a more is commendable. Geomembrane is reinforced modified polyethylene or polyvinyl chloride, and polyester film rolling geotextile heat made with tensile, anti-bursting, high tear strength, elongation properties of good custom Geomembrane, Geomembrane manufacturers deformation modulus, anti-aging, anti-seepage performance, use of a long and so on. After combining it with plastic film, not only increases the tensile strength and puncture resistance of the plastic film, and because non-woven surface roughness increases the friction coefficient of the contact surface is conducive to protective layer of geomembrane and geotextile stable Because of these characteristics the film, in the promotion of the use of channel seepage treatment, and achieved good economic and social benefits. Combined with some of the construction of water-saving irrigation project in Corollary geomembrane. Establish 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 will geomembrane wrinkles surrounding structures, and reveals its produce mechanism. Further by introducing a "variable Poisson's ratio" concept and establish a film based on the theory of wrinkles and folds zone geomembrane stress analysis model deformation tension zone, analyzed under lying soil settlement size, the overburden pressure, geomembrane interface strength . These are related to the geomembrane Xiaobian to introduce you to the promotion and application of the overburden pressure channel seepage control, in fact, no matter what the field is applied, the role of the geomembrane can get the maximum extent. Filtration filtration criteria guidelines for national standard specification proposed geomembrane, geotextile geomembrane used for filtration in accordance with our national standards, "the application of geosynthetics technical specifications" fabric shall conform to the following guidelines. Soil protection criteria Soil protection filtration material shall conform to the requirements of the following formula geotextile equivalent aperture, where, according to the quality of the soil, soil particle size of less than the total size of the soil particles characteristic quality of the soil to determine ; when the soil content of large fines, and when you take a reciprocating flow coefficient determined by engineering experience, should adopt a small value. ) Permeability permeability criteria filtration material shall conform to the formula requirement coefficient, geomembrane determined by engineering experience, not less than the formula determined; shall be the vertical permeability of geotextile permeability practical Geomembrane, soil permeability coefficient) attempts to prevent attempts to prevent the criteria filtration materials should be consistent with the requirements of the column: Sample geomembrane material made in the field of soil and to be selected geotextile clogging test after making the resulting gradient ratio should comply with the following formula When drainage failure and requires huge losses, should be used in the proposed site of geotextile and soil material clogging indoor test. For woven geotextile geomembrane, Soil protection criteria may refer to the following provisions: clay, loam, when the protective layer covering large-block material (sewing clay content greater than woven geotextile represent the equivalent aperture). Under the gap is small (such as precast) conditions, can be slit small sandy soil, covered with a protective layer of geomembrane material in large blocks (clay content less than, whichever is greater, or else take a small value (eg prefabricated Under pieces) conditions, can be; the waves less than quality Geomembrane, Geomembrane Chongqing, new materials provided by Edison Edison Edison New Materials New Materials Co., Ltd (www.fangshenmo. .com) strong, credible, in Dezhou site construction materials industry has accumulated a large number of loyal customers.
