DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a U-shaped groove through which a cable can be routed, a cable holding member, a pack member for cable routing, a cable routing unit, and a cable routing method. Alternatively, the present invention relates to a technique for providing a reasonable means for wiring various cables such as a communication cable.

[0002]

2. Description of the Related Art With the development of an information communication infrastructure, the use of optical fibers in public telephone networks has been promoted. At present, the drawing in of optical fibers to general households is being promoted as needed, and various communication and broadcasting services using the high data transmission speed of optical fibers are about to be started.

FIG. 18 is a diagram for explaining an example of the configuration of an optical subscriber line using an optical fiber cable. The optical fiber cable is generally buried underground in its trunk line, and is taken out of the ground when entering each home or the like and wired overhead by a utility pole. As a method of burying underground, there are a common groove method in which an optical fiber cable can be arranged together with a power cable and a communication cable, and a conduit method in which a buried pipe for an optical fiber cable is prepared and buried.

In FIG. 18, an underground optical fiber cable (C1) connected to a telephone station 101 is pulled out to the ground via a manhole 102, and is wired outdoors using an electric pole 103 as an overhead optical fiber cable C2. An optical star coupler 106 is mounted on the imaginary closure,
Branching is performed using the detachable connector 107. The optical star coupler 106 can be installed in a station, in a stand closure installed underground, or in a subscriber's house. Then, the optical fiber cable drawn into each home via the pull-in post 104 is connected to an ONU (Optical Network Unit) 105 which is an interface for connecting the terminal to the optical fiber, and each terminal 110 is connected via an optical outlet 108. Connected. In the interior of each home, wiring is performed using an optical fiber cable according to the wiring form.

[0005] The above-mentioned optical fiber networks are being developed one after another, but underground burial requires a large amount of cost and construction period, and especially in areas where there are relatively few subscribers such as remote islands and depopulated areas. However, a long-distance laying is required, and a system capable of reducing the cost burden is desired. In addition, not only optical fiber cables but also various cables such as power cables and communication cables often require a rational laying system instead of a common groove system, a conduit system or an overhead wiring using a power pole.

On the other hand, there is a concrete U-shaped groove for forming a side groove for draining rainwater or domestic wastewater. 19 and 20 show a perspective view and a side view of a U-shaped groove unit generally used at present. In each figure, 10 is a U-shaped groove (box body) and 20 is a lid. Figure 1
Reference numeral 9 denotes a lid body 20 configured as an L-shaped
FIG. 20 shows a unit in which the lid 20 is dropped and configured as a lid. Such a U-shaped groove unit is laid as a side groove as described above, the cost is relatively low, and the U-shaped groove unit is often already provided in a depopulated area or a remote island.
