摘要： PROBLEM TO BE SOLVED: To improve economical efficiency by inserting a steel pipe pile provided with a spiral rotary vane at the tip into the leg of a jacket main body, rotatively pressing the steel pipe pile into the underwater ground, then connecting it to the leg. SOLUTION: A jacket main body 1 constituted of legs 2 and horizontal/diagonal braces 3 is erected on the water bottom 4, then a steel pipe pile 6 provided with a spiral rotary vane 5 at the tip section is inserted into each leg 2. A rotary pressing-in device is removably fitted to the apex of the leg 2. The pile 6 is rotated, pressed and intruded into the underwater ground 7 while applying reaction force to the leg 2. A solidifying agent is filled into the gap between the leg 2 and the pile 6 to connect them, and the leg 2 and the pile 6 are separably connected by welding when a jacket is to be removed and shifted for reutilization in the future. When the existing jacket is to be removed and shifted, the connection section of the leg 2 and the pile 6 is cut, and a rotary extracting device is fitted to the apex of the leg 2 to extract the leg 2 while applying rotating force to it. The resistance force for extracting and thrusting the steel pipe pile 6 can be increased, and the steel pipe pile 6 can be made short in length.
