<p><P>PROBLEM TO BE SOLVED: To simplify the laying of an order wire in a pipeline with regard to a pipeline order wire laying device that lays the order wire in the pipeline, and to provide a pipeline order wire laying method. <P>SOLUTION: In this pipeline order wire laying device 1, the end 2a of a vinyl tube 2 that is drawn out of a vinyl tube storing portion 3 is turned over and fixed to an annular fixing portion 4 in such a way that air does not leak. Then, the annular fixing portion 4 is inserted into one opening 53a of a pipeline 53 and compressed air is supplied by an air compressor 43 between the end of the turned-over vinyl tube 2 and is fixed to the annular fixing portion 4 and the outside circumferential surface of the vinyl tube 2 passed through the annular fixing portion 4. Accordingly, the vinyl tube 2 advances along the inside circumferential surface of the pipeline 53 while being turned over, extends toward the other opening 53b of the pipeline 53, and reaches the other opening 53b of the pipeline 53. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
