To provide a grout material closing plug capable of quickly and simply removing a cured grout material, while quickly and simply connecting a branch pipe confluent with an existing sewage pipe and a regeneration pipe confluence port, guiding sewage flowing from the branch pipe to the inside of a regeneration pipe, and preventing a grout material injected into a space between the existing sewage pipe and the regeneration pipe from flowing into the inside of the regeneration pipe, in a sewage pipe regeneration construction method for lining an inner wall of an existing aging sewer pipe with a synthetic resin regeneration pipe.SOLUTION: A plate-shaped grout closing plug comprises a plate-like interior bag that is expandable and contractable with the inflow and outflow of air, and a plate-like exterior bag f that wraps the interior bag. The plate-shaped grout closing plug is expanded in a spiral manner inside a branch pipe B of a sewage pipe and a regeneration pipe confluence port C1, thereby to prevent a grout material from flowing into a regeneration pipe C, and to quickly and easily connect the branch pipe B to the regeneration pipe confluence port C1.SELECTED DRAWING: Figure 5
【課題】老朽化した既設の下水管の内壁に合成樹脂製の更生管をライニングする下水管更生工法において、既設の下水管に合流する枝管と更生管合流口までを迅速かつ容易に連結させ、枝管から流れる下水を更生管内部に導くとともに、既設の下水管と更生管との空間に注入するグラウト材が更生管内部への流入することを防ぎつつ、グラウト材の硬化後に迅速かつ容易に撤去できるグラウト材閉塞栓を提供する。【解決手段】空気の流出入で膨縮自在に設けた板状内装バッグと、該内装バッグを包み込んだ板状外装バッグｆからなる板状クラウド閉塞栓を、下水管の枝管Ｂと更生管合流口Ｃ１内に渦巻き状にしつつ膨張させることにより、グラウト材の更生管Ｃ内部への流入を防ぎ、かつ枝管Ｂと更生管合流口Ｃ１までを迅速かつ容易に連結させる。【選択図】図５
