Abstract

PROBLEM TO BE SOLVED: To obviate a backing material installing margin, to eliminate an increase in an excess wall thickness, and to shorten a work period by previously integrating reinforcements, backing materials and a lining material, and integrally hanging in and installing the wall part and the floor part by a crane in execution work of a nuclear power plant lining storage tank. SOLUTION: A lining material 1, a backing material (the surface) 2, a backing material (the embedding part) 3 and reinforcements 4 are integrally assembled in a factory outside of a nuclear power plant to be transported up to a lining storage tank installing building in the power plant after being transferred on the sea by a carrier vessel, and are integrally hung in by a crane to be arranged on a floor reinforcement so that the reinforcements 4 and the floor reinforcement 11 are connected by grip joints 5. Next, a wall reinforcement 12 is connected to the reinforcements 4 by the grip joints 5, and after connecting the backing material (the embedding part) 3 by an adjacent backing material (the embedding part) 3 and a separator 3, concrete is poured into the part of a wall building frame 7.

することが可能となる。A feature of the present invention is that in a construction method for constructing a lining storage tank, a reinforcing bar, a base material, and a lining material are integrated in advance. In particular, it is a construction method in which a reinforcing bar is penetrated into a buried portion of a base material, integrated, a lining material is welded to the base material, and then the wall and floor are integrally hung by a crane and mounted. That is, according to the present invention, the reinforcing bar is penetrated into the skeleton embedding portion of the lining material and the base material, and integrated, thereby eliminating the need for mounting the base material and unnecessary increase in the wall thickness. . In addition, it is possible to shorten the construction period by hanging and attaching the unit integrally with a crane.
