Document Type and Number:
Japanese Patent JP2018150800
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To perform material throw-in hole block construction in a short period of time by forming a material throw-in hole into an extremely-small hole when constructing an inner tank by withdrawing a steel plate having a flat plate shape or a substantially-circular shape at a cross section constructing an inner tank sidewall from the material throw-in hole which is formed at an outer tank sidewall, in a construction method of a PC/metal double-shell tank having a metal cylinder shell in the outer tank sidewall having a prestressed concrete structure.SOLUTION: A material throw-in hole 10 is opened by a width amount having a margin at a camber of a steel plate 4a toward a tangential direction of a sidewall steel plate 4 (including scheduled construction) of an inner tank 2 in a cross section view, a guide rail which is linear to a tangential direction of a sidewall of the inner tank 2 is laid between the material throw-in hole of an outer tank sidewall, an inner tank 2 and an outer tank 6 from the outside of a sidewall of the outer tank 6, a guide rail which is curved over the whole periphery is laid between the inner tank 2 and the outer tank 6, the steel plate 4a is transported through the material throw-in hole 10 formed at the sidewall of the outer tank 6 when transporting the steel plate 4a to a prescribed position from the outside of the sidewall of the outer tank 6 by hanging it on a plane trolley, and moved to a prescribed position of a metal cylinder shell, thus forming the inner tank 2.SELECTED DRAWING: Figure 1
