<p>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.</p> |
