FORM INSTALLATION METHOD, FORM AND UNDERWATER STRUCTURE
PROBLEM TO BE SOLVED: To provide a form installation method and the like, which can reduce underwater work and which make a form easily self-supportable.SOLUTION: A drilled hole 9 is formed in a water bottom 21, and a sheath pipe 11 is installed in the drilled hole 9. A form 1, in which adjacent form panels 3 are connected together by a steel pipe pile 5, is arranged by inserting a pipe part 5b of the steel pipe pile 5 into the sheath pipe 11. In addition, wire nets 27 and 29 provided in the form panel 3 are stretched to close a gap between the form 1 and the water bottom 21 and a gap between the form 1 and a wall surface of a dam body 2. Furthermore, concrete 7 is injected from inside the steel pipe pile 5, and the drilled hole 9 is filled with the concrete 7 via a hole 15 of the pile part 5b and a hole 13 of the sheath pipe 11 so that consolidation of foundation can be performed.
【課題】水中作業の軽減が可能であり、型枠が容易に自立可能な型枠設置方法等を提供する。【解決手段】水底２１に掘削孔９を形成して、掘削孔９に鞘管１１を設置する。そして、隣り合う型枠パネル３を鋼管杭５で連結した型枠１を、鞘管１１内に鋼管杭５の杭部５ｂを挿入して配置する。また、型枠パネル３に設けた金網２７、２９を広げ、型枠１と水底２１の間の隙間、型枠１と堤体２の壁面との間の隙間を塞ぐ。さらに、鋼管杭５の内部からコンクリート７を注入し、杭部５ｂの孔１５と鞘管１１の孔１３を介して、掘削孔９にコンクリート７を充填して根固めを行う。【選択図】図５
