METHOD FOR CONSTRUCTING CYLINDRICAL TANK

摘要

A method for constructing a cylindrical tank that has a metal inner vessel and a concrete outer vessel. Said method has the following steps: a step in which a precast wall (3) is raised along the outer edge of a base plate (2); a step in which an outer-vessel roof (10) is assembled above the non-outer-edge part of the base plate (2); a step in which, while the precast wall (3) is being raised, the outer-vessel roof (10) above the base plate (2) is lifted by a jack-up device (11) and held by the precast wall (3); and a step in which an inner vessel is assembled independently from the outer-vessel roof (10) in the space, below the outer-vessel roof (10), created by the aforementioned lifting.
