PROBLEM TO BE SOLVED: To provide a prefabricated tank, the inside dimensions of which can be flexibly expanded/contracted by facilitating the construction of a multi-tank structure constituted by connecting a plurality of tanks to one another. SOLUTION: Peripheral walls of the tanks 11, 12, 13, 14, 15, 16 and 17 are constructed on a foundation by horizontally connecting a plurality of prefabricated blocks 2, 3 and 4 together, respectively. The prefabricated blocks include: a vertical wall block 2 which serves as a part of a linearly-elongated wall by making other blocks 2, 3 and 4 connected to two connection end surfaces parallel to each other, respectively; a corner block 3 which serves as a corner for connecting the walls getting closer to each other from two directions, by making the other blocks 2, 3 and 4 connected to two connection end surfaces unparallel to each other, respectively; and a crossing block 4 which serves as a crossing of the walls by making the other blocks 2, 3 and 4 connected to three or more connection end surfaces, respectively. A combination of the three types of blocks 2, 3 and 4 enables the flexible change of the number and dimensions of the tanks for connection. COPYRIGHT: (C)2010,JPO&INPIT
