Patent ID: 8048234

Claim:
Method for cleaning a pipe by the action of a fluid under very high pressure, said method comprising: causing a fluid under very high pressure higher than 15×10 7 Pa to pass through a flexible tube, driving said flexible tube in rotation about a longitudinal axis of said flexible tube by means of rear means for driving the tube in rotation situated at a mobile carriage circulating on a rolling ramp, said mobile carriage having first motorisation means for longitudinal advance of the tube, said first motorisation means for longitudinal advance of the tube being configured for generating and/or maintaining a translation movement of said flexible tube, subjecting said flexible tube to actions of second motorisation means for longitudinal advance of the tube and of front means for driving the tube in rotation about its longitudinal axis, said second motorisation means for longitudinal advance of the tube and said front means for driving the tube in rotation being situated at a rotary casing, regulating said first and second motorisation means for longitudinal advance of the tube and said rear and front means for driving the tube in rotation by means of management means and means for detecting the rotation of the tube and/or pinpointing the longitudinal advance of the tube, wherein said rotary casing is autonomous in terms of motorisation, and can be used alone, fully independently from said mobile carriage, driving said first motorisation means for longitudinal advance of the tube by means of said second motorisation means for longitudinal advance of the tube, or synchronizing said second motorisation means for longitudinal advance of the tube with said first motorisation means for longitudinal advance of the tube, driving said first and second motorisation means for longitudinal advance of the tube and said rear and front means for driving the tube in rotation independently from each other by means of said management means, guiding said flexible tube near an entrance of said pipe so as to clean the pipe by means of the fluid under very high pressure passing through the flexible tube.
