<p><P>PROBLEM TO BE SOLVED: To provide a coupling structure between the head face of a left cable and an extraction jig which enables the head face of the left cable and the extracter to be coupled to each other without fail, even when the redundant length of the terminal of the left cable is hardly exposed from the end face of a duct, so that extraction is difficult, thereby enabling the remaining cable to be extracted surely. <P>SOLUTION: This coupling structure between the head face of a left cable 4 within a cable duct 3, whose head face is exposed from the sidewall 2 of a manhole 1 and the extraction jig, has a plurality of coupling screws 40 which are to be screwed in the head face of the left cable 4, a coupling holder 41 which is to be fixed to the head face of the left cable 4, and the extraction jig for an extractor 36, and the coupling screw 40 is provided with a threading hole, as well as a hollow part, and an adhesive for coupling and fixing the coupling screw 40 and the left cable 4 with each other is sent out from the opening at the peripheral flank of the screw, passing through the hollow part and the threading hole. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
