JACKET, JACKET STRUCTURE, AND JACKET STRUCTURE CONSTRUCTION METHOD
To provide a jacket, jacket structure, and jacket structure construction method that can secure sufficient anticorrosion properties as a water body structure, can shorten the usage period of a work ship, and can shorten the construction period at a site.SOLUTION: A jacket installed above a plurality of piles 80, comprises: a plurality of steel pipe legs 14 having an inner space into which each of the plurality of piles 80 can be inserted; a plurality of upper girders 16 connecting the upper ends of the plurality of steel pipe legs 14 to each other; and an upper steel plate 20 that is attached to the plurality of the upper girders 16 by welding or mechanical joining so as to cover the space between the plurality of the upper girders 16 from above while not covering the inner space of the steel pipe legs 14 from above.SELECTED DRAWING: Figure 1
【課題】水域構造物として十分な防食性を確保でき、また、作業船の使用期間を短くでき、ひいては現場での工事期間を短縮することができるジャケット、ジャケット構造物およびジャケット構造物の構築方法を提供する。【解決手段】複数の杭８０の上方に設置されるジャケットであって、複数の杭８０それぞれを挿入可能な内空部を備える複数の鋼管レグ１４と、複数の鋼管レグ１４の上端部同士を接続する複数の上部桁１６と、複数の上部桁１６に溶接又は機械的な接合で取り付けられ、複数の上部桁１６の間の空間を上方から覆う一方、鋼管レグ１４の内空部は上方から覆わないように構成した上部鋼板２０と、を備える。【選択図】図１
