GROUT SEAL COVER AND GROUT INJECTION METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a grout seal cover, which can be easily fixed underwater and has good workability, and a grout injection method using the grout seal cover.SOLUTION: A grout seal cover comprises: a connection part 7 disposed at a lower end of an opening of a substrate 2, which can suspend a weight 14; seal materials 8,9 disposed on inner peripheral surface of upper and lower ends of the opening; and a filtering part 10 disposed on outer peripheral surface of the substrate, with water quality clarification function. The substrate 2 is formed into a cylindrical shape by wrapping the substrate around circumference across an existing pile 11 and a sheath pipe 12 in a state where the weight 14 is connected to the connection part 7. Ends of the substrate 2 are connected with each other by a water-tight connection body, while a lower end of the sheath pipe 12 is disposed at intermediate position in vertical direction of the seal material 8 on the upper end of the opening. Upper and lower ends of the opening of the substrate 2 are fastened by fastening bodies 5, 6, respectively, and the substrate 2 is fixed to the pile 11 and the sheath pipe 12. Grout G supplied from an upper end of the sheath pipe 12 through an injection hose 13 is injected in a clearance between an outer peripheral surface of the pile 11 and an inner peripheral surface of the sheath pipe 12.SELECTED DRAWING: Figure 1
【課題】水中における装着が容易で作業性がよいグラウトシールカバーおよびこれを用いたグラウトの注入方法を提供する。【解決手段】基体２の開口下端部に重錘１４を吊り下げ可能な接続部７と、開口上下両端部の内周面にシール材８、９と、外周面に水質浄化機能を有する濾材部１０とを設ける。接続部７に重錘１４を接続した状態で基体２を既存の杭１１と鞘管１２とを跨いで外周に巻き付けるようにして筒状に形成し、基体２の端部どうしを水密性を有する連結体で連結する。この際、開口上端部のシール材８の上下方向中途の位置に鞘管１２の下端を配置する。基体２の開口上下両端部をそれぞれを締付け体５、６によって締付けて基体２を杭１１および鞘管１２に装着固定する。鞘管１２の上端部から注入ホース１３を通じて供給されたグラウトＧを杭１１の外周面と鞘管１２の内周面とのすき間に注入する。【選択図】図１
