摘要

A device for cleaning the bore of a pipe, especially a waste water drainage pipe or a sewer, consists of a second pipe (19) of relatively small diameter mounted inside the main pipe (11). The second pipe (19) is mounted at a short distance from the wall of the main pipe and extends over the length of the main pipe. A cleaning medium, such as high pressure water, is supplied to the second pipe and flows out through hole in the pipe wall in the form of jets which impinge on the inside surface of the main pipe. USE/ADVANTAGE - Cleaning device for bore of large diameter pipes. The device can be used without interrupting the use of the pipe.
