Abstract: A method for constructing a double-shell-structured cylindrical tank having an inner tank and an outer tank includes: a step of, inside the outer tank, assembling a first structure of the inner tank excluding a lowermost level of the inner tank by alternately and repeatedly performing raising of an inner tank lateral plate using a jack-up unit and attaching of a next inner tank lateral plate below the raised inner tank lateral plate; a step of assembling a second structure serving as the lowermost level of the inner tank on an annular portion provided on a base portion of the outer tank and configured to support the inner tank; and a step of assembling the inner tank by joining the first structure and the second structure.

Abstract: There is provided a method for constructing a cylindrical tank, including the step of assembling a metal inner tank by individually and sequentially conducting, on an internal side of a PC wall, raising of an inner tank lateral plate by a jack-up unit and welding of a next-stage inner tank lateral plate onto a lower section of the raised inner tank lateral plate, further including the step of installing a guide pair configured to sandwich the raised inner tank lateral plate onto the next-stage inner tank lateral plate that is to be welded therebeneath. As a result, in the case of adopting the jack-up construction system, it is possible to prevent an inner tank lateral plate from being attached next from falling.
