土工膜三水第二個垃圾填埋場白泥坑填埋場可望在年底投入使用在三水區政協主席劉寧等的陪同下，市政協調研組參觀了正在施工的白泥坑垃圾填埋場，調研組成員詳細了解了填埋場的設計規劃，工程進度，管理運營等多方面情況，“隨著三水經濟和城市建設的跨越式發展，城市生活垃圾的處理與利用是一個極為重要的問題，土工膜在白泥坑垃圾填埋場的建設很好地解決了三水急速膨脹的城市及農村生活垃圾處理需求，”楊軍輝表示，三水各界的建土工膜議為三水乃至整個佛山市在生活垃圾處理與利用上提供了有益的借鑒，據悉，白泥坑垃圾填埋場于2009年4月動工，容量950萬立方米，近期的日處理垃圾量約400噸，遠期將增加至1000噸左右，整項工程總投資2.73億元，昨日，三水區國土城建和水務局相關負責人透露，填埋場正處于緊張施工當中，一期填埋區土建工程已完成八成，年底可正式投入使用，---文章來源:中國交通建設集團有限公司5月2日，中交一航局承建的土工膜廠家天津港30萬噸級原油碼頭工程榀碼頭人行鋼橋成功安裝，作為碼頭水工部分 一個分項工程，人行鋼橋的安裝，標志著被譽為天津港標志性工程的30萬噸級原油碼頭水工工程進入收尾階段，據悉，該碼頭共需安裝人行鋼橋8榀，全部鋼橋預計在5月15日前安裝完畢，天津港30萬噸級原油碼頭工程是天津港迄今碼頭等級更大，輸油管線長，碼頭疏浚深，施工難度更大的碼頭工程，是天津市政府為加快濱海新區開發開放，建設北方國復合土工膜際航運中心的重大舉措，它的成功實施，對加快天津港的建設，土工膜促進天津市乃至環渤海地區經濟與社會繁榮發展均具有重要意義。

很多人呢將HDPE土工膜和土工布統稱為土工布，這樣說不能說錯，但也并不準確，兩者都屬于是土工材料系列，但是在用料、使用、功能等多方面有著巨大的差異。其實在接觸過兩種產品后非常容易區分。
土工膜（高密度聚乙烯膜），一種由樹脂顆粒通過高溫融化、擠出生產而成的塑料產品，主要作用是防滲、隔離、增強、防裂、加固、水平面排水等防滲作用， 按產品質量分為城建標準（CJ/T 234-2006）、國標（GB/T 17643-2011）、老國標（GB/T 17643-1998），縱橫向斷裂強度、縱橫向斷裂伸長率、抗穿刺強度等是區分HDPE土工膜標準的重要檢測標準。
無紡土工布，采用 滌綸、丙綸、腈綸、錦綸等加工而成的無紡布，主要作用是反濾、排水、隔離、加筋、防護、密封等作用，按照用料分為長絲土工布（GB/T 17639-2008）和短絲土工布（GB/T 17638-2017），縱橫向斷裂強度、縱橫向斷裂伸長率、抗穿刺強度等是區分土工布標準的重要檢測標準
