になされている。DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of a drain pipe 1 according to the present invention. The drain pipe 1 includes a drain pipe main body 2 and a support rib 3.
And is constituted by. The sewage pipe main body 2 and the support rib 3 are integrally formed by extruding a synthetic resin such as hard vinyl chloride.

上面側に偏った位置に設けられている。支持リブ3の位
置は、下水管の管頂から下水管直径の1/4下に設けら
れている。The shape of the support rib 3 has a protrusion for preventing protrusion. The support rib 3 is provided at a position deviated to the upper surface side when the sewer pipe is laid. The position of the support rib 3 is provided from the top of the sewer pipe to 1/4 of the diameter of the sewer pipe.
【0009】なお、支持リブ3は図1のものに限定され

ければよく、図2のように下水管敷設時の上面側に向か
って湾曲するものであっても構わない。The support rib 3 is not limited to the one shown in FIG. 1, and it is sufficient that the optical fiber cable 4 does not fall off the support rib 3, and the support rib 3 bends toward the upper surface when the sewer pipe is laid as shown in FIG. It does not matter.
【0010】本発明の下水管1に光ファイバーケーブル
4を通線する方法について説明する。A method of passing the optical fiber cable 4 through the sewer pipe 1 of the present invention will be described.
【0011】下水管1を複数本つなぎ合わせて管路を形

げ、支持リブ3に載せる。After connecting a plurality of sewer pipes 1 to form a pipe, the optical fiber cable 4 is pushed in from one end of the pipe so as to slide a part where the sewer originally flows (bottom part of the pipe). When the optical fiber cable reaches the other end, the optical fiber cable is lifted at both ends of the pipe and is placed on the support ribs 3.
【0012】また、直接光ファイバーケーブル4を滑ら

リブ3上を光ファイバーケーブル4を滑らせてもよい。Further, even if the optical fiber cable 4 is not directly slid, the pull-in cable is previously mounted on the support rib 3 by the same method as described above, and then the cable to be pulled in is connected to the end of the optical fiber cable, and The optical fiber cable 4 may be slid over the cable 3.
【0013】またさらに、直接光ファイバーケーブル4

容易になる。As described above, in the sewer pipe according to the present invention, when the wire is passed, the wire is originally passed through the portion where the sewage flows, and thereafter, the optical fiber cable can be mounted on the support rib. Therefore, since it is not necessary to pass through a narrow space, the passing operation becomes easy.
