CONSTRUCTION METHOD OF JACKET STRUCTURE
To provide a construction method of a jacket structure which can more efficiently construct a jacket structure at a predetermined position in an object water area, and can secure higher working safety.SOLUTION: A lower side positioning guide 8 is arranged in a water bottom ground 17 at the neighborhood position of a work frame 5 which is supported by the water bottom ground 17 and is installed on the water, an upper side positioning guide 7 connected to the work frame 5 is made to extend in a horizontal direction, a plurality of cylindrical followers 14 are positioned and erected at predetermined positions of the water bottom ground 17 with upper and lower positioning guides 7 and 8, mounting type excavators 9 are mounted on an upper end of each of the followers 14, the inside of each of the followers 14 is excavated at a predetermined position of the water bottom ground 17 with an excavation bit 11 mounted on a driving shaft 10 extending downward in the same period as installation holes 18, and a fixing part 2 of a jacket structure 1 is fixed to an upper end 3a of each of piles 3 that is inserted and embedded into each of the installation holes 18 to integrate each of the piles 3 and the jacket structure 1.SELECTED DRAWING: Figure 13
【課題】対象水域の所定位置にジャケット構造体をより効率的に構築でき、かつ、作業のより高い安全性を確保できるジャケット構造体の構築方法を提供する。【解決手段】水底地盤１７に支持されて水上に設置された作業架台５の近傍位置で水底地盤１７に下側位置決めガイド８を配置し、かつ、作業架台５に連結した上側位置決めガイド７を水平方向に延在させ、複数本の筒状のフォロワ１４を上側および下側位置決めガイド７、８によって水底地盤１７の所定位置に位置決めして立設し、各フォロア１４の上端部に搭載式掘削機９を搭載して、各フォロア１４の内部を下方に延在する駆動軸１０に取付けられた掘削ビット１１によって水底地盤１７の所定位置に設置穴１８を同時期に掘削し、各設置穴１８に挿入して埋設した各杭３の上端部３ａにジャケット構造体１の固定部２を固定して各杭３とジャケット構造体１を一体化させる。【選択図】図１３
