FIELD: civil engineering; cleaning gas pipe lines, water pipe lines and sewage pipe lines.
SUBSTANCE: proposed device has hollow housing with propulsive nozzles and unit for connection with working agent supply hose and hydraulic drive rotor mounted in housing; it is provided with cleaning tools at its end. Hollow housing is divided in center by means of disk provided with convergent nozzles located at angle relative to its axis forming working angle for communication with rotor blades by means of working agent; rotor blades are made at angle relative to axis of rotation. Hollow housing is additionally provided with inclined nozzles in its front part for motion of device along pipe and for motion of nozzle along rotor axis; spring-loaded guides made in form of knife are articulated in its rear part.
EFFECT: facilitated procedure of manufacture; enhanced efficiency and reliability.
