Geomembrane is widely used in canal leakproof project. In recent years, the applications of geosynthetics in civil engineering, particularly, a large number of applications and effectiveness in flood rescue project, have arroused high attention of the majority of engineering and technical staff. For application technology of geosynthetics, the country has put forward normative technical requirements from seepage, filtration, drainage, reinforcement, protection and other aspects, which has accelerated the pace of the popularization and application of new materials. The material is widely used in seepage-proof projects in canals. I will give a brief account of application technology of geomembrane combined with the construction practice.
Pvc composite geomembrane is around 80 yuan. The price is relatively high in comparison, but the quality is very good, and the cost performance is high. Geomembrane is a geo impermeable material made by taking plastic film as a seepage-proof base material, and compositing it with non-woven geotextile. Its performance depends on impermeable material of the plastic film.
PVC composite geotechnical membrane costs about 100. Composite geotechnical membrane is a water impermeable material made by compositing geotextile fabric and geomembrane. It is mainly used for seepage control, composite geotechnical film is divided into one cloth and one membrane and two cloths one film with width of 4-6m, weight of 200-1500g/m2. The tensile and tearing resistance, bursting and other physical and mechanical performance index is high, and can meet the need for irrigation, municipal, construction, transportation, subways, tunnels and other civil engineering. Because of its selection of polymer materials and anti-aging agent is added in the production process, it can be used in unconventional temperature environment.
