<P>PROBLEM TO BE SOLVED: To provide a jacket installation method for accurately securing the perpendicularity of a jacket foundation while minimizing time and labor required for construction on site in the ocean. <P>SOLUTION: In the method for installing the jacket, which is a foundation structure to be installed in a water area for constructing a structure, the jacket comprises a center leg 1; a plurality of peripheral legs arranged around the center leg; braces 3 for connecting the legs; and an inclination-adjusting/holding device provided in the inside of the center leg 1. The jacket is installed on the underwater ground by (1) a process for driving a center pile into underwater ground, (2) a process for arranging the jacket on the bottom by inserting the center leg 1 of the jacket through the driven center-pile, (3) a process for temporarily connecting the center leg 1 and the center pile with the inclination adjusting/holding device in the center leg 1, (4) a process for inserting and driving piles 5 in the peripheral legs, (5) a process for finely adjusting the inclination of the jacket by the inclination adjusting/holding device inside the center leg 1, and (6) a process for joining the peripheral legs and peripheral piles. <P>COPYRIGHT: (C)2011,JPO&INPIT |
