形鋼支持杭による水上架設構造物のジャケット工法。1. A girder is installed in series between the upper ends of vertical jacket sheath pipes made of steel pipes arranged at required vertical and horizontal intervals, and adjacent jacket sheath pipes are connected by a connecting member, and further adjacent An upper flange made of a steel plate is provided on the outer periphery of the upper end of the jacket sheath pipe, and an annular bottom made of a steel plate is provided slightly below the upper flange. In order to temporarily secure the jacket, which is provided with a flange and is provided with a required number of vertical reinforcing ribs between the upper and lower flanges of the receiving part of the girder, is lifted by a crane and transported to the installation site on the water. At the positions corresponding to the jacket sheath pipes at the plurality of temporary fixing positions set in advance, the temporary fixing support piles made of H-shaped steel are driven into the water bottom in advance, and the upper ends thereof are projected above the water surface. A jacket in which the temporary fixing support pile is inserted into the jacket sheath pipe at the temporary fixing position while suspending the jacket on the temporary fixing support pile and the lower end of the jacket sheath pipe is provided on the temporary fixing support pile. The support pile is supported on a bracket for temporary fixing, and in this state, a supporting pile made of H-shaped steel is lifted by a crane of a work boat for pile driving and inserted into a jacket sheath pipe other than the temporary fixing position of the jacket. After driving into the bottom of the water by a pile driver, a pair of front and rear pile fixing hardware having a vertical pile fixing surface on the upper flange is fixed by bolts, and both flanges of the supporting pile contacting the opposite pile fixing surfaces. Each of which is fastened and fixed by bolts, the surplus portion of the support pile protruding above the pile fixing metal piece is cut, and the temporary fixing support pile is further fixed to the pile fixing member in the same manner as the support pile. H, wherein a jacket method of water erection structure by the supporting piles of H-beams, characterized in that the fastening bolted by hardware
Jacket construction method for floating structures using shaped steel support piles.
