Abstract (en)
A plural drainage pumps PH (3) are disposed on the high floor gradation state at the circular shape (20). A plural drainage pumps PL are disposed on the low floor gradation state at the circular shape (20). The drainage pump PH disposed on the high floor gradation is installed at the high level. The drainage pump PH is set one having the low pump head and the large capacity in comparison with those of the drainage pump PL disposed on the low floor gradation. An outer shape of an underground pump construction building is formed a circular cone shape (20) spreading toward an upper portion. The discharge water power can be reduced and the construction area for the underground pump construction building can be reduced and further the engineering working amount such as a digging working at the underground can be lessen. <IMAGE>
