<p>PROBLEM TO BE SOLVED: To obtain the cable-constraining device of a pipeline, that can prevent unexpected move of a cable in the pipeline and has a simple structure and can be executed easily. SOLUTION: In this cable-constraining device of a pipeline with a constraining tool for constraining a cable 7 that is inserted into a pipeline 2, a constraining tool 21 is provided with a constraining tool body 22, that is inserted between the pipeline 2, and the cable 7 is long in the longitudinal direction of the cable 7, and is made of an elastic body formed into a hollow box shape and a still support 25 for regulating expansion and contraction in the longitudinal direction of the constraining tool body 22. A filler 32 is filled into a filling chamber 24 inside the constraining tool body 22, and the constraining tool body 22 is expanded and pressed to the inner-periphery surface of the pipeline 2 and the outer-periphery surface of the cable 7, thus constraining the cable 7 for the pipeline 2.</p> |
