Abstract
A method for constructing a cylindrical tank which has a metallic inner tank and a concrete outer tank includes a step of building up a PC wall in an outer circumferential edge portion of a base plate, a step of assembling an outer tank roof on the base plate other than the outer circumferential edge portion of the base plate, a step of lifting the outer tank roof which is on the base plate using a jack-up unit while the PC wall is being built up and then holding the outer tank roof on the PC wall, and a step of assembling the inner tank independently of the outer tank roof in a space under the outer tank roof which is created due to the lifting.
