<P>PROBLEM TO BE SOLVED: To provide a cleaning device capable of removing foreign substances adhered in a pipe while keeping cleaning performance even though the inner diameter of the pipe is small in the state of inserting a cable into the pipe. <P>SOLUTION: A cleaning device 5 has a shell form and has a two divided structure having a cable through-hole at the center so as to be able to be easily installed to a cable 4. The body of the cleaning device 5 is vertically divided into two at the center and a plurality of nozzles for spraying in a wide angle to the inner peripheral face of a cable pipe 1 are arranged at equal intervals on the circumferences of the front ends of the divided objects. The divided objects individually have cavity water channels in which a plurality of nozzles communicate with each other in the divided objects. The cavity water channels are individually connected with water supply hoses 6 which are divided into two. High-pressure cleaning water 9 which is sent from a water supply vehicle 16 by the water supply hoses 6 passes through the cavity water channels, is ejected toward a diagonal front from the nozzles and removes foreign substances such as rust, deposits and the like adhered in the inner face of the cable pipe 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
