2. Description of the Related Art Heretofore, as a support structure for a tank of this type, for example, a pedestal is mounted on an upper surface of a foundation made of reinforced concrete, and the tank is mounted on the pedestal. By the way, concrete has the property of shrinking when solidified, but the amount of shrinkage varies. Therefore, after the concrete solidifies, the horizontality of the upper surface of the foundation is not constant. As a result, the greater the length of the tank in the horizontal direction, the lower the level. Therefore, a spacer is interposed between the foundation and the pedestal, and the spacer adjusts the level error of the tank due to the shrinkage of the concrete.
