SOLUTION: The U-shaped groove 10 is provided with a slot 11, capable of being loaded with a cable such as an optical fiber or the like in its longitudinal direction. A cable laying worker loads this slot 11 with a cable to perform work execution. Hereby, a cable wiring means can be provided, in addition to a drainage function being the primary purpose of the U-shaped groove, and the worker can perform low-cost and rational cable laying. Moreover, it is also possible to perform the wiring of the cable after attaching a jig for retention which is capable of retaining a cable. Furthermore, it is also possible to put indoor wiring, etc., into practice, by making use of such a form.</p> |
