建筑复合土工膜的施工方法知识（Knowledge of construction methods of composite geomembrane） Construction method of composite geomembrane Reward points: 0 - solve the time: 2009-8-2 14:05 The composite geomembrane is divided into a film a film a cloth and two cloth can be widely applied in the field of water conservancy dams, airports, roads, drainage, housing, environmental protection etc. the width of up to 6 meters, the membrane thickness from 0.2mm - 0.8mm protective layer of geotextile from 100g/m2 - 800g/m2, and narrow compared to similar products, reduce the mosaic, speed up the construction progress and also reduced due to improper handling of the hidden seam; cloth, membrane separation using composite geomembrane and traditional compared to the use of composite geomembrane to increase the stability of the product, but also saves construction time, reduce project cost, obvious comprehensive benefits; composite geotextile the film is buried laying, long durability, good ageing resistance; water resistance, corrosion resistance, high strength, abrasion resistance, low temperature resistance, non-toxic, flat drainage function is good, good anti-seepage effect; composite geomembrane has Unique thermal insulation, moisture protection, frost protection and anti freezing action. Questioner: fangshui181 - 1, a composite geomembrane construction method 1, 1) for the construction of composite geomembrane material quality testing this project with composite geomembrane is a two film cloth composite geomembrane, Shandong Taifeng plastic geotextile material Co. Ltd production product, before use by Heilongjiang the provincial water conservancy project quality inspection center station for inspection of the product of the technical indicators, the indicators are in line with the standards and design requirements. 2) cleaning, leveling the slope angle, remove all debris, slope under backfill compaction, rich slope cutting dug up after the supervision acceptance, provide working surface of c
