A power driving waste line clean out tool which includes an elongated flexible coil spring formed from an elongated spring wire that is helically wound about a flexible water conduit. The water conduit provides water under relatively high pressure to a uniquely designed water jet clean out head assembly that is affixed to the end of the coil spring and is adapted to effectively break up and remove blockages formed in the sewer line being cleaned. The flexible coil spring is housed within a drum having a conoidal wall through which the coil spring is fed and retracted actually of itself as the drum is rotated. The water jet head assembly of the tool includes a spray head which can be securely connected to the coil spring, a cutter head assembly which can be removably interconnected with the spray head and a connector means of unique design for interconnecting the water conduit of the coil spring assembly with the plurality of water jets provided in the spray head and extending angularly outwardly relative to longitudinal axis of the waste line.

The water conduit provides water under relatively high pressure to a uniquely designed water jet clean out head assembly that is affixed to the end of the coil spring and is adapted to effectively break up and remove blockages formed in the sewer line being cleaned. A portion of the flexible coil spring is housed within a drum having a conoidal wall through which the coil spring is provided with a feed mechanism and is fed and retracted actually of itself as the drum is rotated. The water jet head assembly of the tool includes a spray head which can be securely connected to the coil spring, a cutter head assembly which can be removably interconnected with the spray head and a connector means of unique design for interconnecting the water conduit of the coil spring assembly with the plurality of water jets provided in the spray head and extending angularly outwardly relative to longitudinal axis of the waste line. Also provided proximate the outboard end of the coil spring assembly is a small video camera which is interconnected with a monitor carried by the frame of the device. Power, ground and fiber optic signal transmitting conduits for operating the video camera are carried within the flexible water conduit so that the blockage and the interior of the waste line can be clearly viewed by the operator.

An apparatus for cleaning the interior and exterior of a corroded pipe including a pipe shuttle for rotatable holding a pipe being cleaned, a stationary lance assembly for insertion into the interior of the pipe to scrape and clean the interior of the pipe, an external scraper for scraping the outer surface of the pipe, a wire brush assembly for cleaning the outer surface of the pipe, and a drive car for rotating the pipe and driving the rotating pipe onto the lance assembly and into contact with the external scraper and the wire brush assembly.

A hydrodynamic nozzle for the cleaning of pipes and channels exhibits a distribution chamber (7), joining to the pressurized water-entrance opening (4), wherein the pressurized water-discharge opening (5a, 5b) join into the distribution chamber (7) through channels (6a and 6b). The distribution chamber (7) exhibits a cone-shaped water subdivider (8), to which a defined radius (r1) follows, wherein the curvature of the radius (r1) is opposite to that of the pressurized water-entrance opening (4). The channels (6a and 6b) are merging tangentially at this radius (r1). Furthermore, the nozzle body (1) can be subdivided into an upper part (2) and a lower part (3), and can exhibit a separate form element (14), which forms the water subdivider (8) and the radius (r1), in the lower part (3). The degree of effectiveness is substantially increased with the nozzle according to the invention and thus the axial pressure of the exiting beam of liquid and the cleaning effect is substantially increased.
