摘要
复合土工膜是以聚氯乙烯(PVC)或聚乙烯(PE)塑料薄膜为防渗基材,与无纺布复合而成的土工防渗材料,具有抗拉、抗撕裂、抗顶破强度高,延伸性强,耐腐蚀、耐低温、抗冻性能好,质量轻,施工方便,造价低等特点。复合土工膜防渗技术在库区、坝体、围堰、渠道、人工湖等水利工程中应用广泛。结合在山西省汾河灌区渠系中施工情况,阐述复合土工膜在灌溉渠道防渗中的应用。
Composite geomembrane is geotextile material for anti-seepage made of PVC or PE plastic film and non-woven textile, being tensile resistant, tearing resistant, anti-bursting, extensible, corrosion-resistant, low temperature and cold resistant, light, cheap and easy to build. This anti-seepage technology is widely applied in reservoirs, dams, channels and artificial lakes. The paper, based on the actual construction in Fenhe Irrigation Area in Shanxi, explains the application of this technology.
