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. |
