The intersection of the slope is the bend of the dam slope. The laying and welding of geomembrane are special circumstances. There are many blind ditches in the design at the intersection of the slope and the bottom of the reservoir area, which should be specially cut according to the actual situation.
Two adjacent pieces are welded first, and then pressed into the blind groove. Then properly adjust the position of the pipe sleeve and temporarily fix it with a hot air welding gun, and pass the leachate through the dam pipe, and reinforce it with a stainless steel hoop.
In this area, operators should carefully measure. First, the membrane should be laid along the dam surface 1.5 meters away from the blind ditch, and then connected with the membrane at the bottom of the reservoir. The geomembrane should be cut into an inverted trapezoid with a wide top and a narrow bottom.
These are the main reasons for membrane damage. We must try our best to avoid the damage. There is no provision for geotextile liner material used to protect the anti-seepage geomembrane.
The above is the specific instruction on how to deal with geomembrane if the special parts of the slope are welded.
