PROBLEM TO BE SOLVED: To provide an underwater cutoff method capable of shutting off water by appropriately closing inside the pipeline through which water flows even under water flowing conditions.SOLUTION: The underwater cut-off method under water flowing conditions, includes: a step to dispose a first cutoff member (12, 31) which has a flow path through which water can flow in the central part of a conduit line (3, 22b) through which water is flowing under flowing water conditions (S12); a step to close the flow path (12a, 31a) of the first cutoff member (12, 31) by means of a second cutoff member (13) (S15); and a step to inject a curable liquid or a fluid of water-stopping agent at the upper stream side of the first cutoff member (12, 31) and the second cutoff member (13) inside the conduit line (3, 22b) through which water flows (S13,S17).SELECTED DRAWING: Figure 1
【課題】流水環境においても、当該水が通流する管路内を好適に閉塞し止水し得る水中止水方法を提供する。【解決手段】流水環境における水中止水方法は、水が通流する管路（３，２２ｂ）内に、中央部に水を通流可能とする流路を有する第１止水部材（１２，３１）を配する工程（Ｓ１２）と、第２止水部材（１３）により第１止水部材（１２，３１）の流路（１２ａ，３１ａ）を閉塞する工程（Ｓ１５）と、水が通流する管路（３，２２ｂ）内であって、第１止水部材（１２，３１）及び第２止水部材（１３）の上流側に、硬化性の液体又は流動体である止水剤を注入する工程（Ｓ１３，Ｓ１７）と、を備える。【選択図】 図１
