Composite geomembrane, widely used in channel anti-seepage engineering. In recent years, the extensive application and effectiveness of geosynthetics in civil engineering, especially in flood control and rescue projects, has attracted the attention of engineers and technicians. For the application technology of geosynthetics, the state has put forward normative technical requirements from the aspects of anti-seepage, anti-filtration, drainage, reinforcement, protection, etc., which has greatly accelerated the promotion and application of new materials. The material has been widely used in the anti-seepage project of irrigation area, and the application technology of composite geomembrane is discussed in combination with construction practice.
Construction attentions:
(1) The use must be buried: the thickness should not be less than 30cm.
(2) The refurbishment prevention system shall have: a cushion layer, an anti-seepage layer, a transition layer and a protective layer.
(3) The soil should be solid to avoid uneven subsidence, cracks, and turf and roots within the anti-seepage range. A sand or clay having a small particle size is laid as a protective layer on the contact surface with the film.
(4) When laying, the geomembrane should not be pulled too tightly, and the two parts buried in the soil part are corrugated, especially when anchored with rigid materials, there should be a certain amount of expansion and contraction.
(5) During construction, stones should be avoided, and heavy objects should be placed directly on the geomembrane. It is best to lay the film while covering the protective layer.
