PROBLEM TO BE SOLVED: To provide a sand pack, an underwater structure and a construction method of the underwater structure.SOLUTION: A sand pack 10 is made by filling a filling material 12 into a bag body 11 in a tube shape with both ends closed. An anchor seat 13, which has a hanging function, a scour preventing function at the water bottom and a fixing function of the bag body 11, is installed on a part of the bag body 11 to integrate with each other. The water structure is installed by grounding the sand pack 10 on the water bottom and spreading the anchor sheet 13 to cover the water bottom. The construction method of the water structure comprises following processes: to support the anchor sheet 13 connected along a longer direction to a bottom of the bag body 11 by multiple salvage barges to hang the bag body 11; to form the sand pack 10 by filling the filling material 12 in the bag body 11 while the bag body 11 is hung underwater; to install the sand pack 10 at the water bottom by rolling out and submerging the anchor sheet 13; and to spread and fix the anchor sheet 13 on the water bottom.

    【課題】サンドパックと、水中構造物と、水中構造物の構築方法を提供する。【解決手段】両端を閉鎖したチューブ状を呈する袋体11の内部に中詰材12を充填してなるサンドパック10であって、袋体11の一部に吊り下げ機能、水底の洗掘防止機能、および袋体11の固定機能を併有するアンカーシート13を一体に付設する。そして、水中構造物は、水底にサンドパック10を着底させ、アンカーシート13を展開して水底を被覆する。また、水中構造物の構築方法は、袋体11の底部に長手方向に沿って連結したアンカーシート13を、複数の台船で支持して、袋体11を水中に吊り下げる工程と、水中に吊り下げたまま、袋体11に中詰材12を充填して、サンドパック10を形成する工程と、アンカーシート13を繰り出しながら沈降させて、水底にサンドパック10を設置する工程と、アンカーシート13を水底に展開して固定する工程と、を含む。【選択図】図1
