Geomembrane, widely used in canal seepage engineering, especially in flood rescue works in a large number of applications and their effectiveness, 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 obtained in the irrigation canal seepage is widely used in engineering customized geomembrane, combined with the construction practice, the application of technology of composite geomembrane. Geomembrane (composite impermeable membrane) into a cloth membrane and two cloth one membrane, width 4-6m, weighing 200- geomembrane workshop 1500g / sqm, tensile, tear, bursting, etc. physical and mechanical properties is high, the product has high strength, good elongation properties, deformation modulus, acid, corrosion-resistant, 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. Geomembrane is in one or both sides after the film far infrared heating oven geomembrane, geotextile and geomembrane by the guide roller pressed together to form a composite geomembrane. With the improvement of the production process, there is a casting process do geomembrane. In the form of a cloth membrane, two cloth one film, two films a cloth. Geomembrane laying process also have certain requirements, and only act in strict accordance with these procedures, to be able to make a good engineering job. The process is divided into geomembrane while digging, while the shop, while tamping, while retaining a consistent flow of new geomembrane, and carry out the cycle of operations. Geomembrane laying process, the first step is to pay attention to the process, the second step is to focus on the base surface cleaning. Base surface cleaning step is very important, surface cleaning requirements must take good, because this is a critical step to ensure that the effect. Especially for those items with sharp dissection of a clean, smooth base surface to maintain, can not appear uneven local phenomenon until after the cleanup is complete. Also with tamping rammer ram plate or tight, so as to ensure smooth solid base surface. The third step is to geomembrane laying, laying when we must pay attention while laying on the ground from under the laying process must be maintained between the membrane and the substrate surface and the membrane and the membrane between the tightness flatten each must take between snapping, keep in close connection between the layers. Because geomembrane very thin light specials geomembrane, so in the process of laying prone to bubbles, and can easily be blown dry. To prevent the kill, so every once paved area is not too large, so while laying geomembrane while laying a protective layer. The fourth step is laying a protective layer and surface protection, this step is very important. Before laying the protective layer, a protective layer of soil material must take good sieving screening, can not have large particles, so it is easy to pierce the geomembrane. In laying the protective layer of soil material of the time, do dense thickness. In the process of filling material should be gently, avoid civil torn membrane. The last step is to connect the surrounding community treatment, this step is to prevent soil geomembrane and the surrounding relationship, such an action would require the closure of the entrance flow in the peripheral must dig the cut sinks, and must take the composite geotextile cut film on the sink.
