Claim Text:
1. A storage tank construction method comprising: a step of forming a side wall while a temporary opening is provided; a step of fitting precast concrete slabs into respective inner and outer wall sides of the temporary opening to close the inner and outer wall sides of the temporary opening, each of the precast concrete slabs including a first surface and a second surface opposite to the first surface, and the first surfaces of the precast concrete slabs facing each other when the precast concrete slabs are fit into the respective inner and outer wall sides of the temporary opening; and a step of pouring concrete between the precast concrete slabs using the precast concrete slabs as molds to block the temporary opening, wherein metal plates are previously bonded to the first surfaces of the precast concrete slabs, wherein a first connecting fitting which is configured to be connected to a side-wall connecting fitting embedded in the side wall is embedded in the precast concrete slab fit into the inner wall side of the temporary opening so that the first connecting fitting is exposed to the first surface of the precast concrete slab fit into the inner wall side of the temporary opening, wherein a shape of the metal plate, which is bonded to the first surface of the precast concrete slab fit into the inner wall side of the temporary opening, has a shape that avoids a position at which the first connecting fitting is embedded in the precast concrete slab, and wherein a second connecting fitting which is configured to be connected to a side-wall connecting fitting embedded in the side wall is embedded in the precast concrete slab fit into the outer wall side of the temporary opening so that the second connecting fitting is exposed to the second surface of the precast concrete slab fit into the outer wall side of the temporary opening.
