Artificial lake impermeable material impermeable geomembranes

Geomembrane play in artificial lake seepage good effect. Paper, the geomembrane from the design selection to construction methods and quality control are described proposed geomembrane selection method under the membrane area construction process water, the product gas and geomembrane, three major problems that must be solved stage design and construction. Construction of composite geomembrane geomembrane construction picture is on one side or both sides of the film through an oven far-infrared heating, the geotextiles and geomembranes through guide roll together to form a composite geomembrane. With the improvement of the production process, there is a casting method do geomembrane process. In the form of a cloth membrane, two cloth one film, two films a cloth. As geotextile geomembrane layer of protection, so that impermeable layer of protection from damage. To reduce ultraviolet radiation to increase the anti-aging properties, preferably laying buried in France. Construction, the first to use a smaller diameter material leveling sand or clay base surface, and then laying the geomembrane. Geomembrane not stretched too tightly, buried in the soil at both ends of the body portion is corrugated, and finally in the shop geomembrane layer of about 10cm intermediate layer of fine sand or clay. Lined with 20-30cm stone (or precast concrete blocks) for the anti-scour protection layer. Construction, should try to avoid the stones hit directly on the geomembrane, preferably side to side laying protective layer construction. Geomembrane connection with the surrounding structures should be used to the pressure of the expansion anchor bolts and steel connecting parts to brushing emulsified asphalt (thickness 2mm) adhesive to prevent leakage there
