摘要
土工膜是用聚乙烯或聚氯乙烯的增强改性,压延成膜与涤纶针刺土工布热合而成,具有抗拉、抗顶破、抗撕强度高,延伸性能好,变形模量大,耐老化,防渗性能好,使用期长等特点。土工膜由于具有上述特点,在渠道防渗处理中推广采用,取得了良好的经济效益和社会效益。结合胜利灌区节水续建配套工程中土工膜的施工情况,阐述土工膜在渠道防渗处理中的应用。
Geo-membrane was made from polyethylene or PVC enhancing modification, recycle film formation and Dacron acupuncture geo-textile heat seal. The characteristics of resisting to tensile, weather and bursting, good extension,large modulus of deformation,good anti-seepage ability,long service period enable geo-membrane widely used at canal anti-seepage, which procured favorable socioeconomic benefit. The paper gave some discussions on geo-membrane application in the Shengli Irrigated Area.
