/><br /> </span> </p> <span style="font-family:'Microsoft YaHei';font-size:18px;line-height:2.5;"> 1 工藝流程：干旱地區鋪設復合土工膜防滲采取邊挖、邊鋪、邊夯、邊護的區段循環作業。</span><br /> <span style="font-family:'Microsoft YaHei';font-size:18px;line-height:2.5;"> 2 基面清理：基面一定在按設計要求清理好，這是確保防滲效果的關鍵，特別是對尖石、樹根等雜物要徹底清除干凈，基面不允許有局部凹凸現象。</span><br /> <p> <span style="font-family:'Microsoft YaHei';font-size:18px;line-height:2.5;"> 3 復合土工膜鋪設：鋪膜時，一定要由上下而上鋪設。膜與膜之間及膜與基面之間要壓平貼緊，但不宜將膜拉得過緊，一般要略松一點，但不能在膜底留有氣泡。接頭有熱粘、膠粘、搭接等方法，本工程設計采用膠粘，接縫寬50mm。若發現土工膜的刺破或撕破之處，一定要用三倍于破損面積的土工膜膠粘貼補好 </span> </p> <p> <span style="font-family:'Microsoft YaHei';font-size:18px;line-height:2.5;"> 4 保護層及護面：靠土工膜10cm厚的保護層土料一定要過篩，不允許有粒徑大于6mm以上顆粒，否則易刺破土工膜。保護層土料一定要用夯打密實，保證干容重在1.5以上，并隨時取樣檢驗?；靥畋Ｗo層及砌筑塊石護面時，一定要輕放，以免撞破土工膜。干砌塊石采取人工掛線鋪砌，石塊應緊密嵌固，面層塊石個體重量應大于48kg，所有空隙均用小塊石充填。</span> </p> <span style="font-family:'Microsoft YaHei';font-size:18px;line-height:2.5;"> 5 周邊接界處理：周邊接界處理的要求是將復合土工膜與周邊土體聯結緊密，封堵滲流入口，截斷側向的滲漏路徑，防止滲水進入土工膜底面，形成水泡，在庫水位下降時脹破土工膜。因此周邊接界一定要挖截水槽，并將土工膜埋入槽內。</span><br /></div>

style="text-align:center;"> <span style="font-family:'Microsoft YaHei';font-size:18px;line-height:2.5;"><img onload="resize(this,700)" src="/upload/image/20160808/20160808144714_37018.png" alt="" /><br /> </span> </p> <span style="font-family:'Microsoft YaHei';font-size:18px;line-height:2.5;"> 1 工藝流程：干旱地區鋪設復合土工膜防滲采取邊挖、邊鋪、邊夯、邊護的區段循環作業。</span><br /> <span style="font-family:'Microsoft YaHei';font-size:18px;line-height:2.5;"> 2 基面清理：基面一定在按設計要求清理好，這是確保防滲效果的關鍵，特別是對尖石、樹根等雜物要徹底清除干凈，基面不允許有局部凹凸現象。</span><br /> <p> <span style="font-family:'Microsoft YaHei';font-size:18px;line-height:2.5;"> 3 復合土工膜鋪設：鋪膜時，一定要由上下而上鋪設。膜與膜之間及膜與基面之間要壓平貼緊，但不宜將膜拉得過緊，一般要略松一點，但不能在膜底留有氣泡。接頭有熱粘、膠粘、搭接等方法，本工程設計采用膠粘，接縫寬50mm。若發現土工膜的刺破或撕破之處，一定要用三倍于破損面積的土工膜膠粘貼補好 </span> </p> <p> <span style="font-family:'Microsoft YaHei';font-size:18px;line-height:2.5;"> 4 保護層及護面：靠土工膜10cm厚的保護層土料一定要過篩，不允許有粒徑大于6mm以上顆粒，否則易刺破土工膜。保護層土料一定要用夯打密實，保證干容重在1.5以上，并隨時取樣檢驗?；靥畋Ｗo層及砌筑塊石護面時，一定要輕放，以免撞破土工膜。干砌塊石采取人工掛線鋪砌，石塊應緊密嵌固，面層塊石個體重量應大于48kg，所有空隙均用小塊石充填。</span> </p> <span style="font-family:'Microsoft YaHei';font-size:18px;line-height:2.5;"> 5 周邊接界處理：周邊接界處理的要求是將復合土工膜與周邊土體聯結緊密，封堵滲流入口，截斷側向的滲漏路徑，防止滲水進入土工膜底面，形成水泡，在庫水位下降時脹破土工膜。因此周邊接界一定要挖截水槽，并將土工膜埋入槽內。</span><br />', bdDesc
