摘要:
A process is disclosed for inspecting subsidiary canals that branch off from a main drain. A camera probe (24) is deflected from the main drain pipe (10) into the branching off subsidiary, canal pipe (12) by means of a deflecting frame (22; 76; 96). The process is characterized by a propulsion by reaction of the camera probe (24), a fluid under pressure being supplied to reaction jets (34; 90) mounted on the camera probe so as to drive the latter into the subsidiary canal pipe (12).
