<p>PURPOSE:To simplify cable laying by installing a cable supporter to a high-level road constructed in an urban area, by holding a power cable with this cable supporter and by laying the power cable along the road. CONSTITUTION:A hole 12 is formed to the side of a road section 1a of a road 1, into which a cable supporter 5 is fixed by the use of an anchor bolt. These cable supporters 5 are fixed in large numbers to the side of a road section 1a in three stages at equal intervals in the extended direction of the road 1. A power cable 3 in each stage is fastened to the cable supporters 5 and laid in the extended direction of the road 1. In this way, in order to protect the power cable 3 laid to the side of the road section 1a of the road 1 and to prevent the power cable 3 from dropping, a cover 4 to cover the power cable 3 is divided in large numbers in the extended direction of the road 1 for maintenance and checking to the side of the road section 1a and is installed to the road section 1a with clamps so as independently to open and close freely.</p> |
