An optical fiber sensor installation structure for a pipe line is provided to perform the installation of the optical fiber sensor even when a power cable installation process is completed by moving a line of the optical fiber sensor using a transfer power of a transfer medium inside the pipe line. A sealing member(20) is inserted into and fixed on an inlet hole of a pipe line(12). A power cable(10) is buried in the pipe line along with a tube path. A through-hole(24) is formed on the sealing member, so that a transfer medium and an optical fiber sensor line(14) are transferred between the power cable and the sealing member. A supply unit(30) for supplying the transfer medium(26) is connected into the through-hole. When the transfer medium flows from one to the other end of the pipe line under the control of the supply unit, the line of the optical fiber sensor is guided with the transfer medium. |
