WATER TANK DIVIDING METHOD, WATER TANK, AND WALL BODY

摘要

PROBLEM TO BE SOLVED: To provide a water tank dividing method in which a water tank can be divided by a wall body without discharging stored liquid from the water tank capable of easily reducing a gap between an inner wall face or a bottom face of the water tank and an end part of the wall body.

SOLUTION: The water tank dividing method includes: a first step for providing the wall body in the water tank in which liquid is stored so that the end part of the wall body is along the inner wall face and the bottom face of the water tank; and a second step for reducing at least one of gaps between the end part of the wall body and the inner wall face or the bottom face. The second step includes a third step for providing a hollow member having hollow expansibility being along at least one of gaps between the end part of the wall body and the inner wall face or the bottom face; and a forth step in which fluid is filled in the hollow member.
