The upper and lower geotextiles of the composite geomembrane
After laying a composite geomembrane in a small dam pond, the water shortage problem in nearby villages was completely solved. The composite geomembrane should be laid in dry and warm weather. In order to facilitate splicing and prevent stress concentration, the composite geomembrane is laid in a wave-shaped relaxation manner, with a margin of about 1.5%. After paving, it should be leveled and opened in time. It is required that the composite HDPE geomembrane factory price should be flush with the slope surface, and should not be folded, suspended, or without protruding folds. Construction personnel should wear flat cloth shoes or soft rubber shoes, and spiked shoes are strictly prohibited to avoid stepping on the geomembrane; fires must not be introduced into the construction site, and construction personnel must not smoke on the construction site; if the geomembrane is damaged during construction, repair it in time.
The upper and lower geotextiles of the composite geomembrane are seam welded, and the HDPE geomembrane for sale is welded by heat. In order to ensure the welding quality, the overlapping surface of the weld should be free of water, dust, and oxide scale, and there should be no impurities such as dust, sand, and water that affect the welding quality. The two connected geomembranes must be lapped smoothly and loosened. The welding quality of composite geomembrane is the key to the anti-seepage performance of composite geomembrane.
The bottom and periphery of the HDPE geomembrane manufacturers must be tightly integrated with the anti-seepage foundation and dam slope, that is, the anchor groove must be excavated below the relative anti-seepage layer. The geomembrane should be crimped and anchored in the trench as designed. The backfill soil in the trench must be screened and cleaned, and the cleaned soil must not contain debris that can easily pierce the geomembrane. When backfilling, the geomembrane should be compacted to ensure that the geomembrane is firmly anchored.
