MANHOLE PUMP UNIT

PURPOSE:To enhance operating performance in execution by connecting the discharge port of an underwater pump packaged within a manhole to the entrance of a discharge connecting pipe connected to a discharge pipe which is penetrated through the manhole, with a flexible pipe. CONSTITUTION:Sewage inflow pipes 9A and 9B are arranged from two directions while being penetrated through the circumferential.wall of a manhole 1, and one discharge pipe 3 penetrating through the circumferential wall at a position above the aforesaid pipes, is arranged in the direction different from the aforesaid directions, so that a discharge connecting pipe 4 is thereby connected to the inner end section of the discharge pipe within the manhole 1. And a fork connecting member 10 such as a nipple which has two inflow side passages 4A and 4A of the connecting pipe 4 collected into one outflow side passage 4B, is threadedly connected to the aforesaid inner end section within the manhole 1. And the check valve 14 are connected to each entrance of the inflow passages 4A and 4A, so that the discharge ports 2A of a pump 2 are mutually connected to each entrance of the connecting pipe 4 with two flexible pipes 12. By this constitution, time required by piping design can thereby be saved much.
