In addition, since it is configured by filling a large number of perforated hollow shells in close contact with each other, the effective capacity of the underground water storage structure is increased by the large void portion provided in the perforated hollow shells, and a large amount of stored water is stored. It can be stored in a flowable and efficient manner, and a large number of perforated hollow shells with a predetermined rigidity are closely packed and installed in the void area, so that the weight of the underground water storage structure, the overlaid load, or the surrounding ground It is possible to effectively support the earth pressure from and to simplify the structure of the underground water storage structure. That is, despite the simple structure, it is possible to efficiently store the stored water by increasing the effective capacity for storing the stored water such as rainwater and to stably use the stored storage water. .
