<p>PROBLEM TO BE SOLVED: To easily draw out a cable by a method, wherein a lubricant is applied to the inside of a conduit in which the cable is laid over the entire length securely and uniformly to reduce a drawing-out force and then the drawing-out force of the cable is further reduced. SOLUTION: A predetermined quantity of lubricant 7 is poured into a conduit 1 in which a cable 2 is laid from one end. After a space filling member 6, which is soft and has elastic stability is pushed into the conduit 1, high pressure air is supplied into the conduit 1 from one end to convey the space filling member 6 by pressure to the other end in order to apply the lubricant 7 to the inside of the conduit 1. After that, the cable 2 is drawn out from the other end, while high pressure air is supplied into the conduit 1 from one end.</p> |
