To shorten an installation period and stably fix even a short embedment by excavating installation holes providing a width widening part on a water bottom to insert the fixing embedment part of an underwater structure and injecting a solidifying agent for foot protection.
The water bottom 2 of an installation planned jobsite is excavated to construct installation holes 21 so as to provide a bottom widening part 211. The shape of the bottom widening part 211 is triangular, rectangular or the like in a side shape, and circular in a planar shape. A jacket 4 composes steel pipes and steel materials of a framework structure, and each leg is composed of a pile single body. A fixing projection 411 such as a dowel and a ring is mounted on the outer periphery of each leg 41. The jacket 4 assembled on a land is transported to a jobsite to be installed on the water bottom 2, and a solidifying agent 7 such as concrete is placed in the installation holes 21 inserting each leg 41. The solidifying agent may be injected through a fixing embedment inside. In addition, an installation leg part may be integrally mounted on the bottom of the jacket. Thus jobsite working hours can be remarkably reduced and an initial stable measure can be simplified.
