  • ABSTRACT A method for assembling a tank is disclosed in which the uppermost side plate or shell and a roof are assembled on a bottom placed upon a foundation to form the uppermost shell assembly and an air-tight sealing mechanism is disposed within the uppermost shell assembly. The compressed air is introduced into the shell assembly so as to float the same to a predetermined height, and the segments or blocks of the next side plate are placed below the floated uppermost side plate and welded thereto. The above steps are cycled until the lowermost side plate is assembled and the assembly of the tank is completed.

It is not required to lock the cover 22 in the closed position with the use of bolts and nuts, but it suffices only to have the cover made into contact with the inner surface of the roof 15 in order to provide the air-tightness.
  • FIGS. 15-19 The third embodiment to be described in detail with reference to FIGS. 15--19 as being applied to the assembly of a single-shell dome roof tank is substantially similar to the first embodiment described with reference to FIGS. 3-7 except that a balancing device 25 is used in order to hold upright the first shell assembly when the latter is floated.
