Abstract

PURPOSE:To provide the self-propelling force drawing a washing hose to a piping washing apparatus itself by forming the second jet orifices to the cylindrical part of a nozzle support body in an oblique direction so as to make the self-propulsion of the piping washing apparatus possible. CONSTITUTION:When high pressure washing water is supplied to a washing hose 12 from a pump, at first, the washing water flows in the cylindrical part 13a provided to one end of a nozzle support body 13 from the insertion end part 12a of the washing hose 12. A part of the washing water is injected from the second jet orifices 15 and a piping washing apparatus X advances while draws the washing hose 12 to the deep part of a pipe. The remainder of the washing water flows in the cylindrical part 13b provided to the other end of the nozzle support body 13 through the flow path 17 of a nozzle 18 to be injected from the first jet orifice 20. When the washing water is injected from the first jet orifice 20, non-equilbrium propelling force acts on the nozzle 18 and the nozzle 18 is moved toward the inner wall 11a of the pipe 11. Whereupon, the slide member 25 of a nozzle guide member 24 comes into contact with the inner wall 11a. At this time, the slide member 25 is pressed to the inner wall 11a in such a state that rotatory power is generated by the repulsive force of the nozzle.
