ABSTRACT:
A plurality of drainage pumps are disposed on a high floor gradation state in a circular arrangement. A plurality of drainage pumps are disposed on a low floor gradation state in a circular arrangement. The drainage pumps disposed on the high floor gradation are installed at a high level, with the drainage pumps having a low pump head and a large capacity in comparison with the drainage pumps disposed at the low floor gradation. An outer shape of an underground pump construction building is in the form of a circular cone shape spreading toward an upper portion of the underground pump construction building. The amount of power for discharging the drainage can be reduced and the construction area for the underground pump construction building can be reduced thereby minimizing the necessary requirement for installation of the underground pump construction.
