Construction precautions：
Geomembrane in the transportation process do not drag, hard pull, to avoid sharp objects stabbing.
1, should be extended from the bottom to the high, do not pull too tight, should leave a 1.50% margin for local subsidence and stretching.
2, the longitudinal joints of the two adjacent pieces should not be on a horizontal line, should be staggered more than 1m.
3, the longitudinal joint should be more than 1.50m away from the dam foot and bend foot, and should be located on the plane.
4, the first slope behind the bottom.
5, when the slope is laid, the film direction should be basically parallel to the maximum slope line.
