Construction Method of HDPE Geomembrane

Do not drag or forcefully pull the geomembrane during transportation to avoid sharp objects stabbing it.
1. Extend from the bottom to the high position, do not pull too tightly, and leave a margin of 1.50% for local sinking and stretching. Considering the actual situation of this project, the slope is laid in a top-down sequence;
2. The longitudinal joints of two adjacent frames should not be on the same horizontal line and should be staggered by more than 1m from each other;
3. The longitudinal joint should be located at a distance of more than 1.50m from the dam foot and bend foot, and should be located on a plane;
4. First slope, then site bottom;
5. When laying the slope, the direction of film spreading should be basically parallel to the maximum slope line.
