<p><P>PROBLEM TO BE SOLVED: To provide a column type pump unit in which a column type submerged pump is installed in a square manhole, and a water suction tank, a water discharge tank, and the pump are integrated with one another. <P>SOLUTION: A water suction tank 2 with a discharge tank 4 of a square block-shaped block placed therein is installed in a water flow passage A. A flowing water suction port 3 is opened in the water suction tank 2, and a discharge port 5 communicating with a water discharge passage B is opened in the water discharge tank 4, respectively. A column 6 housing a submerged pump 14 is suspended from a partition wall 11 between the water suction tank 2 and the water discharge tank 4 to constitute a column type pump unit 1. The pumping station space is reduced according to the situation of the flowing water passage A, the construction period can be shortened even in a narrow site, the construction can be executed at a low cost, and an existing pumping station can be reinforced. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
