Construction method of HDPE geomembrane for landfill site

Landfill construction.jpg

HDPE geomembrane full name "high density polyethylene geomembrane, have good environmental stress cracking resistance, low temperature resistance, anti-aging, corrosion resistance, and the use of large temperature range (60 - + 60) and a longer service life of 50 years, widely used in domestic waste landfill site seepage control, solid waste landfill anti-seepage, sewage treatment plant of seepage control, artificial anti-seepage, tailings disposal such as seepage control projects.

HDPE geomembrane construction method:

Geomembrane in the process of transportation do not drag, hard pull, avoid sharp objects stab.

1. Extend from the bottom to the high position, do not pull too tight, and leave 1.50% of the remaining width for local sinking and stretching.Considering the actual situation of the project, the slope should be laid from top to bottom.

2. The adjacent longitudinal joints should not be on a horizontal line and should be staggered by more than 1m;

3. The longitudinal joint shall be more than 1.50m away from the dam foot and bend foot, and shall be located on the plane;

4, the first slope back bottom;

5. When the slope is laid, the spreading direction should be basically parallel to the maximum slope line.
