A stacked structure especially useful for storing water in the underground is formed of a plurality of skeleton members. Each skeleton member includes a plurality of skeleton parts extending in one direction and situated side by side in a lateral direction perpendicular to the one direction. Each skeleton part has one top portion, and two bottom portions extending from the top portion, wherein one bottom portion in one skeleton part is connected to one bottom portion in the adjacent skeleton part. Also, each skeleton part includes top recesses formed at the top portion to be spaced apart from each other at a predetermined interval, and bottom recesses formed at the bottom portions to be spaced apart from each other at a predetermined interval. The skeleton members form upper and lower skeleton members to be vertically stacked together. The skeleton parts of the upper and lower skeleton members extend perpendicularly to each other. The bottom recesses of the upper skeleton member are located in the top recesses of the lower skeleton member so that the upper and lower skeleton members are securely assembled together.
