Construction method of Geomembrane:

1. The slope should be laid from the top to the bottom, and should not be pulled too tightly. A margin of 1.50% should be reserved for local subsidence and tension.
2. The longitudinal joints of two adjacent frames shall not be on a horizontal line, and shall be staggered by more than 1m;
3. The longitudinal joint should be more than 1.50M away from the dam toe and bending foot, and should be set on the plane;
4. When the slope is laid, the film spreading direction should be basically parallel to the slope line.
5. In construction, the sand or clay with small diameter should be used to level the base surface, and then the geomembrane should be laid. The geomembrane should not be stretched too tightly. The parts embedded in the soil at both ends are wavy. On the geomembrane, a transition layer of about 10cm is paved with fine sand or clay.
