PURPOSE: An apparatus for cleaning an inside of an old water pipeline of medium and large sizes is provided to extend the length of frames according to the size of an old water pipeline with hydraulic pressure because the number of the frames can be decreased or increased according to pipe diameters.;CONSTITUTION: An apparatus for cleaning an inside of an old water pipeline of medium and large sizes comprises a high-pressure water supply pipe(50), a spraying unit(200), and a cover(60). The cleaning apparatus is moved into an old water pipeline by the rotation of a wheel(32). High pressure cleaning water is supplied to the high pressure water supply pipe of the spraying unit through a high pressure hose(52). After the cleaning water is supplied to an inner chamber of a head(54) coupled in the front end of the high pressure water supply pipe, the cleaning water is collided to a rear inclined portion of the cover. Accordingly, eddy current is generated. The cleaning water is sprayed to the internal side of the old water pipeline through nozzle pipes(66) after being discharged to a discharge passage of the head, thereby removing foreign materials generated in the internal side of the old water pipeline.;COPYRIGHT KIPO 2013
