Composite geomembrane has strong vitality and multiple properties
Composite geomembrane is a composite product of geomembrane and geotextile, which is laid flat on the dam slope. Geomembrane is a basic anti-seepage material, which plays the role of anti-seepage. The geotextile protects the geomembrane produced by LDPE geomembrane manufacturers from external damage during transportation and construction and improves the friction coefficient of the membrane surface. Composite geomembrane has strong vitality and multiple properties, which can meet engineering needs. In addition, due to its lightweight, simple construction, convenient transportation, low price, and abundant material sources, it is widely used in water conservancy projects and traffic tunnel projects.
During the construction process, after the dam’s slope cleanliness and flatness are qualified, the relevant operators need to backfill and anchor with C25 concrete. The tooth groove is 1.5m wide and 0.5m high; anchor the dam crest at the bottom of the wave wall, To ensure the suitability of the length of the geotechnical model, and backfill the concrete in the trench; dig a trench with a bottom width of 1.0m, a top width of 2.0m, and a depth of 1.0m at the junction of the dam on both sides and the mountain, and anchor the high quality LDPE geomembrane into the trench Inside and then compacted with clay.
When laying the dam, it is best to construct in weather with low air humidity to ensure smooth splicing and improve construction efficiency. Laying should be wave type, pay attention to the slack between the working film and the working film, as far as possible to ensure the adhesion between the working film and the slope, to avoid wrinkles. At the same time, during the laying process, the construction personnel must pay attention to the choice of shoes, so as not to damage the appearance of the working film.
