淺談垃圾填埋場工程中糙面防滲膜的施工質量控制-北京中瑞環?？萍脊こ坦?/title> <meta name="description" content="在鋪設糙面防滲膜之前，土建基層面要滿足“四度”要求：平整度（±2cm/m2,平整順直）；壓實度（95%，經碾壓后方可在其上鋪設糙面防滲膜）；縱、橫坡度（縱、橫向坡度均宜不小于2%[3] ，填埋場底部的輪廊邊界和結構必須有利于滲瀝液的導流）"

target="_blank">防滲膜</a>之前，土建基層面要滿足“四度”要求：平整度（±2cm/m2,平整順直）；壓實度（95%，</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">經碾壓后方可在其上鋪設糙面防滲膜）；縱、橫坡度（縱、橫向坡度均宜不小于2%[3] ，填埋場底部的輪廊邊</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">界和結構必須有利于滲瀝液的導流）；清潔度（垂直深度2.50cm內不得有樹根、瓦礫、石子、砼顆粒等尖棱雜</span><span style="font-family:'Microsoft

style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;"> 二、鋪設糙面<strong><a href="http://www.sandbad1.com/" target="_blank">防滲膜</a></strong>時應從底部向高位延伸，不要拉得太緊，應留有1.50%的余幅，以備局部下沉拉伸。邊坡</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">采取從上到下的鋪設順序?？v向接頭應距離壩腳、彎腳處1.50m以上，應設在平面上。相鄰兩幅的縱向接頭不</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">應在一條水平線上，應相互錯開1m以上。先邊坡后場底，邊坡鋪設時，展膜方向應基本平行于最大坡度線。 </span> </p> <p> <span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;"> （一）邊坡、場底鋪設控制：防滲土工膜在邊坡鋪設前，先對鋪設區域進行檢查、丈量，根據丈量的尺寸將倉</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">庫內尺寸相匹配的防滲膜運至一期錨固溝平臺，鋪設時根據現場實際條件，采取從上往下“推鋪”的便利方式。在</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">扇形區應合理裁剪，使上下端都得到牢固的錨固。 </span><br /> <span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;"> （二）對正、搭齊：糙面防滲膜的鋪設不論是邊坡還是場底，應平整、順直，避免出現褶皺、波紋，以使兩幅</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">防滲膜對正、搭齊。搭接寬度按設計要求，一般為10cm左右。 </span><br /> <span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;"> （三）壓膜的控制：用砂袋及時將對正、搭齊的糙面防滲膜壓住，以防風吹扯動。風力超過4級或雨天應停止施</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">工。 </span><br /> <span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;"> （四）錨固溝內的鋪設控制：在錨固溝頂部，應按設計要求預留一定量的防滲膜，以備局部下沉拉伸。 </span><br /> <span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;"> （五）縱向接縫：上坡段在上，下坡段在下，并且留有足夠的搭接長度（不小于15cm）。</span> </p> <p> <span style="font-family:'Microsoft

target="_blank">防滲膜</a>之前，土建基層面要滿足“四度”要求：平整度（±2cm/m2,平整順直）；壓實度（95%，</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">經碾壓后方可在其上鋪設糙面防滲膜）；縱、橫坡度（縱、橫向坡度均宜不小于2%[3] ，填埋場底部的輪廊邊</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">界和結構必須有利于滲瀝液的導流）；清潔度（垂直深度2.50cm內不得有樹根、瓦礫、石子、砼顆粒等尖棱雜</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">物）。</span> </p> <p> <span style="font-family:'Microsoft YaHei';"><span style="font-size:16px;line-height:32px;"><br /> </span></span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;"> 二、鋪設糙面<strong><a href="http://www.sandbad1.com/" target="_blank">防滲膜</a></strong>時應從底部向高位延伸，不要拉得太緊，應留有1.50%的余幅，以備局部下沉拉伸。邊坡</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">采取從上到下的鋪設順序?？v向接頭應距離壩腳、彎腳處1.50m以上，應設在平面上。相鄰兩幅的縱向接頭不</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">應在一條水平線上，應相互錯開1m以上。先邊坡后場底，邊坡鋪設時，展膜方向應基本平行于最大坡度線。 </span> </p> <p> <span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;"> （一）邊坡、場底鋪設控制：防滲土工膜在邊坡鋪設前，先對鋪設區域進行檢查、丈量，根據丈量的尺寸將倉</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">庫內尺寸相匹配的防滲膜運至一期錨固溝平臺，鋪設時根據現場實際條件，采取從上往下“推鋪”的便利方式。在</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">扇形區應合理裁剪，使上下端都得到牢固的錨固。 </span><br /> <span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;"> （二）對正、搭齊：糙面防滲膜的鋪設不論是邊坡還是場底，應平整、順直，避免出現褶皺、波紋，以使兩幅</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">防滲膜對正、搭齊。搭接寬度按設計要求，一般為10cm左右。 </span><br /> <span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;"> （三）壓膜的控制：用砂袋及時將對正、搭齊的糙面防滲膜壓住，以防風吹扯動。風力超過4級或雨天應停止施</span><span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;">工。 </span><br /> <span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;"> （四）錨固溝內的鋪設控制：在錨固溝頂部，應按設計要求預留一定量的防滲膜，以備局部下沉拉伸。 </span><br /> <span style="font-family:'Microsoft YaHei';font-size:16px;line-height:2;"> （五）縱向接縫：上坡段在上，下坡段在下，并且留有足夠的搭接長度（不小于15cm）。</span> </p> <p> <span style="font-family:'Microsoft
