OCEANIC STRUCTURE, AND INSTALLATION METHOD FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an oceanic structure that keeps costs low by improving workability of installation work for superstructure work, and an installation method for the same.SOLUTION: An oceanic structure includes: a foundation 2 that is provided in such a manner as to partially penetrate the seabed ground; superstructure work 3 that is provided in an upper section of the foundation 2; and an angle adjusting member 4 that is interposed between the foundation 2 and the superstructure work 3 and that can adjust an installation angle of the superstructure work 3 with respect to a vertical direction. The angle adjusting member 4 has two shim plates 20 (20A and 20B) superposed on a concentric shaft. Each of the shim plates 20 is characterized in that one surface is inclined with respect to the other surface.
