PURPOSE:To make a high-pressure water injection direction optionally settable by drawing a hose, connected to a high-pressure pipe via each swivel joint at a turnable center and a reel shaft end, out of a reel, in a high-pressure flusher for a sewer pipe or the like. CONSTITUTION:A high-pressure flushing car 1 supports a reel 13 on a base 2 via a turnable 4 free of rotation in horizontality and around a shaft, and connects the terminal of a hose 15 rolled on the reel 13 to a high-pressure pipe 20 out of a pressure machine via a second swivel joint 12 at a reel shaft end, a pipe 20, and a first swivel joint 19 at the turnable center. At time of flushing, the hose 15 is drawn out of the reel 13 via a guide member 37 free of horizontal rotation and thereby a nozzle being attached to a tip of the hose 15 is directed in the optional direction, and high-pressure water is sprayed toward a desired position. Thus, extraneous substances sticking to the inside of a flushed pipe are easily and positively scraped off and, what is more, these extraneous substances can be prevented from leaving behind. |
