OPENING PORTION CLOSING METHOD, OPENING PORTION CLOSING STRUCTURE, AND CLOSING MEMBER
PROBLEM TO BE SOLVED: To provide an opening portion closing method, an opening portion closing structure, and a closing member capable of surely charging a hardener to a circumference of an interference object of an opening portion filled with water, and preventing outflow of the hardener.SOLUTION: In a method of closing an opening portion 5 by charging an in-water inseparable hardener to the opening portion 5 provided with an interference object 8 and filled with water, a bag mouth 16 of an elastic bag-shaped water-permeable inner net member 18 is mounted on a tip portion 14 of an injection pipe 12 for injecting the hardener to the opening portion 5, a bag-shaped water-permeable outer net member 20 for restricting bulging of the inner net member 18, is mounted in a state of covering an outer side of the inner net member 18, then the tip portion 14 of the injection pipe 12 is disposed on the opening portion 5, and the hardener is discharged from the injection pipe 12 toward the inside of the inner net member 18, so that the inner net member 18 is expanded and the opening portion 5 is closed.
【課題】水で満たされた開口部の干渉物の周りに硬化材を密実に充填することができ、硬化材の流出を阻止することのできる開口部閉塞方法、開口部閉塞構造および閉塞部材を提供する。【解決手段】干渉物８が設けられ、水で満たされた開口部５に水中不分離性の硬化材を充填することで開口部５を閉塞する方法であって、硬化材を開口部５に注入するための注入管１２の先端部１４に、伸縮性を有する袋状の透水性の内側ネット部材１８の袋口１６を取り付けるとともに、この内側ネット部材１８の外側を被覆するように、内側ネット部材１８のはらみ出しを拘束するための袋状の透水性の外側ネット部材２０を取り付けた後、注入管１２の先端部１４を開口部５に配置し、注入管１２から内側ネット部材１８の内部に向けて硬化材を吐出し、内側ネット部材１８を伸張させて開口部５を閉塞するようにする。【選択図】図３−１
