不要であり、重要な幹線道路に広く期待されている。However, when the inner peripheral wall 1 is newly installed in a ditch, a cave or the like, excavation work is required, and the ditch or cave is buried under an important highway. If there is, it is necessary to carry out excavation work from the main road. Therefore, it is necessary to stop the traveling of the main road on which the vehicle or the like travels, and the travel of the main road users is stopped.
Therefore, a reinforcing structure has been proposed that reinforces the inner peripheral wall 1 such as an existing groove or cave. In such a reinforced structure, since the inner peripheral wall 1 such as an existing groove or cave is reinforced, no excavation work is required and it is widely expected to be an important highway.

上させることができる。According to the reinforcing structure 10 for a cable laying path such as a ditch or a cave, the cable laying path 12 is reinforced to target the cable laying path 12 on which the cable 5 is laid. Since the reinforcing body 15 composed of a plurality of segments 20 for reinforcing the inner peripheral surface of the laying path 12 and the metal plate 3 attached to the reinforcing body 15 and supporting the cable 5 are provided, the existing inner peripheral wall 1 has a plurality of members. By arranging the segments 20 of 1, the existing inner peripheral wall 1 can be reinforced by the reinforcing body 15, and the cable 5 can be supported by the uprights 3 arranged in the cable laying path 12. For this reason, the existing inner peripheral wall 1 can be dismantled and new construction work for the inner peripheral wall 1 can be dispensed with, and the excavation work can be unnecessary from the main road. Therefore, the existing cable laying route can be used without restricting the use of the main road. 12 can be reinforced, and the workability of reinforcing the cable laying path 12 can be improved.

Since the uprights 3 are fitted in the box-out portions, that is, the notches 27 facing each other, the cross-sectional area of the existing inner peripheral wall 1 is the reinforcing body 15.
Even when the reinforcing body 15 is narrowed, the hollow cross-sectional area of the reinforcing body 15 can be suppressed from being further narrowed by the upright 3. Therefore, the workability of storing the cable 5 in the upright 3 can be prevented from being deteriorated, and the hollow cross-sectional area of each segment 20 can be secured, so that the inspection passage for the cable 5 can be provided in the existing cable laying passage 12. It can be secured, and the reinforcing body 15 can be built in the existing cable laying path 12.
