膨潤土防滲毯施工
膨潤土防滲毯施工
一、材料
所選用的膨潤土防滲毯具有國家或部門認可的測試單位的測試報告，證件齊全，并按施工規范的規定進行現場抽樣，送到具有相應資質的實驗室進行檢測，檢測合格后才能使用。使用前進行外觀檢查，如有撕裂、穿洞、侵蝕等損壞的不得使用。

二、運輸、裝卸與保管
膨潤土防滲毯在運輸過程中捆牢、蓋嚴實、確保產品安全。
裝卸過程中防止尖銳物品對包裝及產品的損害，禁止采用鋼絲繩吊裝裝卸，防止膨潤土防滲毯受損或變形。
運抵工地后妥善保存，避免防潮、防滲、放水，儲存時采用方木或其它物品墊起來，確保產品不與水接觸。在運輸、施工、存放過程中防止日光暴曬，避免強度受損；膨潤土防滲毯存放采取防水措施，露天存放必須采用苫布、塑料布等覆蓋嚴實，防止

Second, transportation, handling and storage
Bentonite seepage blanket truss during transport, cover tight, and ensure product safety.
Loading and unloading sharp items to prevent damage to the packaging and products, prohibiting the use of wire rope lifting handling to prevent damage or deformation of bentonite seepage blanket.
After arriving at the site properly, avoid moisture, seepage, water distribution, storage, use party when the mat of wood or other materials up to ensure the product is not in contact with water. Transport, construction, to prevent sunlight exposure during storage to avoid damage intensity; bentonite waterproofing impervious blanket storage, open storage must be Tarpaulins, plastic sheeting and other cover tight, and prevent
