An apparatus for removing sedimented sludge of a sewage reservoir is provided to promptly and conveniently discharge sludge sedimented in a sludge manhole through a dredging pipe by using a dredging pump without manual work of workers in the sewage reservoir. A sewage reservoir(110) has a first space part(111) for collecting sewage inside, a first cover(112) formed at a top side, an inlet pipe(113) for receiving sewage and a discharge pipe(114) for discharging sewage, which are formed at both sides, an inner bottom with an inclined plane(115), and a sludge discharge port connected with the inclined plane. A sludge manhole(120) is installed adjacently to the sewage reservoir, having a second space part(121) for collecting the sludge discharged through the sludge discharge port, and a second cover(123) formed at a top side. A dredging pipe(130) has a horizontal part formed by bending a lower end horizontally and a curve part formed by bending an upper end in a semicircular shape. The dredging pipe is attached to an inner surface of the sludge manhole vertically. A dredging pump is attached to the horizontal part of the dredging pipe for discharging the sludge within the sludge manhole to the outside. |
