Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an installation method of a jacket structure that facilitates positioning of a jacket structure to be installed and enhance work efficiency of the installation work.SOLUTION: A jacket structure 1 is moved downward using a crane 7, and a connection part 2a of the jacket structure 1 is fitted first with a top edge part 4 in the air of a pile 3a that has already been installed in a ground 9. Each connection part 2 and the top edge part 4 of each pile 3 are fixed after positioning the jacket structure 1 using the pile 3a that was fitted first. Or, a guide member 5 may be provided on at least either of the top edge part 4 in the air of the plurality of piles 3 installed in the ground 9, or the connection part 2. Then, the jacket structure 1 is moved downward using the crane 7 to have each connection part 2 and the top edge part 4 of each pile 3 guided by the guide member 5 and fitted for positioning the jacket structure. Furthermore, each connection part 2 and the top edge part 4 of each pile 3 are fixed.SELECTED DRAWING: Figure 1
【課題】据え付けるジャケット構造体の位置決めを容易にして、据え付け工事の作業効率を向上させることができるジャケット構造体の据え付け方法を提供する。【解決手段】クレーン7を用いてジャケット構造体1を下方移動させて、ジャケット構造体1が有する接続部2aと既に地盤9に打設されている杭3aの気中にある上端部4とを最初に嵌合状態にして、最初に嵌合状態にした1本の杭3aを利用してジャケット構造体1を位置決めした後、各接続部2と各杭3の上端部4とを固定する。或いは、地盤9に打設してある複数本の杭3の気中にある上端部4と各接続部2の少なくとも一方に、ガイド部材5を設けておき、クレーン7を用いてジャケット構造体1を下方移動させて、各接続部2と各杭3の上端部4とを各ガイド部材5によって誘導して嵌合させた状態にして位置決めした後、各接続部2と各杭3の上端部4とを固定する。【選択図】図1 |
