Title:
SEWAGE PUMP STATION
Document Type and Number:
Japanese Patent JP3955651
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent sludge and the other contaminant from being deposited, by a structure for minimizing the projecting parts inside a sewage pump station provided with a plurality of submergible pump units.
SOLUTION: To reduce the number of projecting parts inside a tank of a pump station, two connecting units 10 are attached on a wall 2 steeply inclined into a funnel shape or an inclined rack 15 provided with the rounded transition section as an integral formed part so as to be faced to each other in the reverse attitude in which they are extremely approached to the wall 2. To minimize the diameter of the tank, the connecting units 10 are so arranged as to be deflected toward the tank center with the deflection angle of 5° to 10°. To secure sufficient suabiity, the connecting units 10 are fixed on a horizontal tank bottom 3. The steep inclined surface 16 of the tank bottom 3 positioned between two connecting units 10 is so designed to form the gradient toward the center part of the tank.
