METHOD FOR REMOVING SEDIMENT ACCUMULATED UNDERWATER
PROBLEM TO BE SOLVED: To provide a method for removing sediment accumulated underwater that reduces costs for processing industrial wastes and costs for transporting sediment, at the same time efficiently removing sediment that has accumulated, or will accumulate underwater.SOLUTION: A bag body 1 and an air flow generator 21 are installed on a water bottom 13. The bag body 1 and the air flow generator 21 are towed by a towing ship 17 or a winding mechanism 19 and moved on the water bottom 13. In the process, sediment 23 on the water bottom 13 is excavated using an excavation blade 9 protruding from a frame body 7, a guiding air flow is generated using the air flow generator 21 to entrain the excavated sediment 23, and the sediment 23 on the water bottom 13 is taken into the bag body 1 through the frame body 7. Then, a towing rope 11 is wound using the winding mechanism 19 to pull up the bag body 1 above water 15, the frame body 7 is removed from an opening part 5 of the bag body 1, and the opening part 5 is closed with a rope or other closing tool 25. Furthermore, excess water inside the bag body 1 is dehydrated to reduce a volume thereof, to be used as a construction material.SELECTED DRAWING: Figure 2
【課題】産業廃棄物処理に係る費用や土砂の運搬費用を低減し、水中に堆積したあるいは将来堆積する土砂を効率良く除去できる水中堆積土砂の除去方法を提供すること。【解決手段】袋体１と空気流発生装置２１とを水底１３に配置する。そして、牽引船１７や巻き取り機構１９を用いて袋体１と空気流発生装置２１とを牽引して水底１３で移動させる。このとき、枠体７から突き出した掘削刃９を用いて水底１３の土砂２３を掘削するとともに、空気流発生装置２１を用いて空気による誘導流を発生させて掘削した土砂２３を巻き込み、水底１３の土砂２３を枠体７を介して袋体１の内部に取り込む。その後、巻き取り機構１９で牽引ロープ１１を巻き取って袋体１を水上１５に引き上げ、袋体１の開口部５から枠体７を取り外し、ロープ等の閉合具２５で開口部５を閉合する。さらに、袋体１の内部の余剰水を脱水して減容し、工事材料として活用する。【選択図】図２
