Geomembrane, widely used in canal seepage control project. In recent years, geosynthetics in civil engineering, especially in a large number of applications and their effectiveness in flood rescue project, causing the majority of engineering and technical staff are highly valued. Geosynthetics for the application of 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 irrigation canal seepage control project, combined with the construction practice, the application of technology of composite geomembrane. Pressure measurement geomembrane Hydrostatic 1. Determination of geomembrane Hydrostatic pressure on both sides of the principles in the geomembrane head reaches a certain value, geomembrane will break. Progressively increased on both sides of the water sample beat keep and maintain a certain time, when the rapid increase in seepage flow PE composite membrane manufacturers, said the sample is damaged, it won the hydrostatic pressure value of the sample. 2. Keep the pressure geomembrane at least 2h, observing seepage canal water level changes, geomembrane level basically stable (seepage flow is zero), places 0.1-0.2mpa, progressively increasing the pressure differential for each level are maintained 2h, until the emergence of the phenomenon of seepage flow increased rapidly, indicating that the specimen rupture has occurred after a pressure that is as hydrostatic pressure (mpa). 3. Just as geomembrane geomembrane determine whether the sample reaches a specified value Hydrostatic latest PE film, you can direct pressure to this pressure and maintain 2h, then judgment is in line with requirements. 4. Determination of geomembrane at least three samples of each sample, the sample with the lowest value as hydrostatic pressure. Geomembrane (composite impermeable membrane) into a cloth membrane and two cloth one membrane, width 4-6m, weighing 200- geomembrane workshop 1500g / m2 PE composite film, tensile, tear, physical and mechanical properties of bursting and other indicators of high, the product has high strength, good elongation properties, deformation modulus, acid, corrosion resistance, 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. Commonly used in dams, drainage ditch seepage treatment, as well as pollution prevention and waste treatment field has a kind of new composite geomembrane - Warp composite geomembrane. Warp geomembrane synthetic fibers (or fiberglass) as reinforcing material, with geomembrane geotextile composite made of new materials. Unlike warp geomembrane geomembrane. Its greatest feature is the intersection of the warp and weft bend, each in a flat state. Tie the line to both tightly and evenly fully synchronized external force, the distribution of stress, and when the instantaneous utility PE film applied force tearing the material, will be the beginning of yarn along rip pro set, increased tear strength . When warp complex, namely the use of warp bundled line between the weft and non-woven waterproof acupuncture staple fiber geotextile layer repeatedly walk through, so became one of the three series. Thus both warp geomembrane characteristics of high tensile strength, low elongation, and both waterproof geomembrane. Therefore, a warp of geomembrane increased with the reinforcement, isolation, protective effect of impermeable material. It is the high level of international applications today geotextile composites. Special PE film, PE film Florida, Edison new materials and new materials provided by the Edison Company.
