Geomembrane with impermeable plastic film as a substrate, and non-woven geotextile composite made of impermeable material, its performance depends on impervious impermeable plastic film performance. At present, the application of impermeable plastic film at home and abroad, mainly polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), also designed to use the tunnel applications ECB (ethylene-vinyl-modified bitumen blend geomembrane), which is a flexible material polymer chemistry, the proportion of small well-known geomembrane, extension of the strong ability to adapt to high deformation, corrosion resistance, low temperature, frost performance. Construction Method: Do not drag geomembrane during transport, hard pull geomembrane quality and avoid sharp objects stabbed. 1, the bottom should be extended to high, do not pull too tight, should leave more than 1.50% of the increase, to prepare for local subsidence stretch. Taking into account the actual situation of the project geomembrane price, take the slope from top to bottom of the laying sequence; 2, two adjacent longitudinal joints should not be in a horizontal line, should be staggered over 1m; 3, the vertical joints should distance dam feet, legs bent at 1.50m above, should be located in the plane; 4, after the end of the first slope field; 5, when the slope laying show films should substantially parallel to the direction of maximum slope line.
