Key Points of Anti-seepage Membrane in Artificial Lake Application

  • Release on:2019-10-08
In recent years, with the development of urban construction and the improvement of people's living standards, theenvironmental function of water has received more and more attention. Artificiallakes have appeared in public playgrounds, residential areas, universities and other places. As an artificial lake anti-seepage material, geomembrane has theadvantages of light weight, large elongation, good anti-seepage performance,adaptability to deformation, simple construction and low cost.

First, the choice of anti-seepage materials

The anti-seepage membrane is the most important material for artificial lake seepage prevention. Therefore, it is necessary to select a suitable high-quality geomembrane(Highway Maintenance Nonwovens Vendor) first, and it is alsonecessary to consider the construction convenience. When choosing ageomembrane, pay attention to the following points:

1) When the thickness of the film is lessthan 0.35 mm, when the hot-melt welding machine is used in the field, the welding process is difficult to hold, and the leakage of the geomembrane(PET Non Woven Felt Factory) iseasily caused by the quality of the welding.

2) During the lamination process, welds,especially cross welds, should be minimized to reduce leakage hazards.

3) In addition, the water depth of the general artificial lake is about 3m and the depth is up to 5m. Therefore, it isnecessary to ensure that the strength of the geomembrane(Non Woven Geotextile Wholesale) is sufficient, and thefoundation of the artificial lake is crucial. Once the foundation is deformedto a large extent, the geomembrane will With stand various loads.

Therefore, the most important characteristics of the choice of geomembrane are: the thickness of the geomembrane should be more than 0.5mm; the width is recommended to use the widthof 8m, most of the domestic manufacturers are producing 7m geomembrane. Thegeomembrane produced by Soma in Canada is 8 meters wide, and the geomembranecan effectively reduce the weld seam compared with 7 meters; the punctureresistance, environmental stress cracking resistance and right angle tearstrength are also very important indicators; geomembrane Softness.
