    Abstract: An object of the present invention is to provide a utility pole and a method for constructing the utility pole, which can simplify and improve efficiency of work at the time of new construction and replacement and can shorten a work period.
    The anchor has a larger diameter than a body of a utility pole on the ground and has higher ground support force. Thus, the hole for building the assembly type utility pole on the ground can be made shallower than the hole for building the utility pole in related art on the ground. The depth of the hole is shallow, so that it is possible to reduce a period for digging, reduce a probability of hitting a buried object, and reduce work for confirming a buried object. In addition, the assembly type utility pole includes a plurality of parts, and thus, only a degraded portion needs to be replaced, so that it is possible to shorten replacement work. Further, the assembly type utility pole includes a plurality of parts, and thus, each part is smaller than that of the utility pole in related art, so that it is possible to simplify work.

    Abstract: An object of the present invention is to provide a cable laying method that enables efficient work.
    A cable laying method according to the present invention includes: preparing a structure 31 having a hook 32; fixing a cable 50 to the hook 32 attached to a surface of the cap-type structure 31 on the ground in the vicinity of a pole 11 built on the ground 10; lifting the structure 31 up to the vicinity of a tip of the pole 11; and covering the tip of the pole 11 with the structure 31. This cable laying method eliminates the need to work in high places. This cable laying method is efficient because it eliminates the need to work in high places.

    Abstract: An object of the present invention is to provide a monitoring device and an optical fiber identification method capable of efficiently identifying an optical fiber at a construction site.
    The monitoring device 71 includes a light receiver 74 that receives an optical signal SL leaked from an optical fiber, a counter 75 that counts the number of unique numbers indicating transmission sources included in the optical signal SL, and a display unit 76 that displays the number of unique numbers. The monitoring device 71 further includes a control unit 77 that causes the display unit 76 to display that a portion where the optical signal SL has leaked is between the 8-branch splitter 51 and the OLT 11 when the number of unique numbers is two or more, and that causes the display unit 76 to display that it is unknown whether a portion where the optical signal SL has leaked is between the 8-branch splitter 51 and the OLT 11 or between the 8-branch splitter 51 and the ONU 21 when the number of unique numbers is one.

    Abstract: An object of the present invention is to provide a pole erection method capable of efficiently and safely erecting a utility pole with a small number of operators even in a construction environment in which heavy machines cannot be used.
    The pole erection method according to the present invention includes preparing a structure 60 having a cylindrical shape in which, when the structure is erected perpendicularly to the ground with one end 60a facing down, a part of an edge 61a at the other end 60b is higher than the other part of the edge 61b (step S01), burying one end 60a of the structure 60 in the ground (step S02), placing a lower end portion 10a-1 of a utility pole 10a lying on the ground on the other part of the edge 61b of the structure 60 (step S03), pressing the lower end portion 10a-1 of the utility pole 10a against an inner wall 62 (step S04), and lifting up an upper end portion 10a-2 of the utility pole 10a with the other part of the edge 61b as a fulcrum while pressing the lower end portion 10a-1 of the utility pole 10a against the inner wall 62, and sliding down the utility pole 10a into a cavity 63 of the structure 60 to erect the pole (step S05).
