翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Fiber roll ： ウィキペディア英語版 Fiber roll A fiber roll is a temporary erosion control and sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and seas from sediment erosion. It is made of straw, coconut fiber or similar material formed into a tubular roll. ==Installation== Each horizontal contour level row of fiber rolls is installed on slopes, ending with one at the base of the slope, below an active construction area before soil disturbance (earth moving) begins. The space between each row of fiber roll is dependent on the steepness of the slope. The steeper the slope, the more rows of evenly spaced horizontal contour level fiber rolls are used. Each fiber roll is installed on a horizontal contour level in shallow trenches 2 to 4 inches (5 to 10 cm) deep and fastened to the ground with wooden stakes. Properly installed fiber rolls are effective at trapping sediment, generally more effectively than straw bales.〔(California Stormwater Quality Association. ) Menlo Park, CA. ("California Stormwater BMP Handbook: Fiber Rolls." ) Fact Sheet No. SE-5. January 2003.〕〔U.S. EPA. ("National Menu of Stormwater Best Management Practices: Fiber Rolls." ) June 1, 2006.〕 During rain storms, the rolls intercept surface stormwater runoff (but not concentrating or channeling the runoff) and reduce the velocity of flow. Water passes through a fiber roll while leaving behind the sediment on the uphill side of the roll, thereby reducing sediment erosion. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fiber roll」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
