CLEANING DEVICE FOR A SYSTEM OF PIPES

摘要

A device for cleaning a system of pipes or a system of underground channels (2) has at least one access opening (3), which device (6) comprises a flexible pressure line (10), which at one end is connected to a spray head (7, 8), which can be placed in the said system via the access opening (3) and is provided with at least one nozzle (8) for delivering a jet of flushing medium, and at the other end is connected to a pressure device (11), as well as a support member (9) on which the spray head can be moved through the system. At least one of the nozzles (7, 8) is directed along the pressure line in order to deliver a jet of flushing medium which is directed backwards along the said pressure line (10), in such a manner that in operation a tensile force is exerted on the pressure line (10).
