<p>PROBLEM TO BE SOLVED: To provide a sewage pipe for passing an optical fiber cable that can be easily jointed and laid without requiring a special cutting tool or the like while being prevented from the generation of a diagonal cut, a burr at a pipe end part, dislocation of an optical fiber cable passing pipe, and the like. SOLUTION: An optical fiber cable passing pipe 5 is provided with an integrated bracket part 52 extended in a pipe axis direction while connecting the outer surface of a plurality of (two) optical fiber cable passing pipe single pipe parts 51. Holding pins 61, 63 of a holding fitting 6 are inserted in a holding pin insert hole 21 bored in the top part of a pipe body 2 of a sewage pipe 1 and a holding pin insert hole 53 bored in the bracket part 52 of the optical fiber cable passing pipe 5. The optical fiber cable passing pipe 5 is thereby laid being supported to the inner surface of the pipe body 2 of the sewage pipe 1.</p> |
