がある。In the above-mentioned situation, it is unavoidable that the buried depth of the underground buried object 4 in the portion of the roadway 3 becomes shallower than that of the other portions, and therefore, when repairing the road, for example, concrete is used. When a road is cut with a cutter, there is a risk that the underground buried object 4 will be cut by mistake. C. In the case of BOX, there is a risk of leading to an accident of cutting the buried cable.

形成するのである。Therefore, according to the present invention, as shown in FIGS. 2 and 3, a plate-shaped base steel plate 6 made of pure iron, which is relatively soft and has low strength and excellent ductility, is provided above the underground buried object 4. Since the block steel plate 7 is formed by a large number of strip steel plates 6 ′ having the same strip shape and having the same quality along the edge of the upper surface of the base steel plate 6 and a frame-shaped steel plate 6 ″ that bundles the periphery of these steel plates 6 ′. is there.

According to the present invention, the base steel plate 6 prevents cutting and placing from the upper part by the cutter, and the frame-shaped steel plate 6 '' counteracts the entrance of the cutter from the side. Since the base steel plate 6 is formed into individual strips, even if a notch is formed, only the steel plate 6 at that portion is damaged, and the frame-shaped steel plate 6 ″ is formed relatively narrow. Therefore, the burden on workers can be reduced.

のである。The earth and sand layer 9 is laid in the above-mentioned state, and the concrete layer 10 is formed on the earth and sand layer 9. The road surface is cut by the diamond blade of the concrete cutter during the road repair work. When hitting the protective plate 5 composed of the block steel plate 7 and the block steel plate 7, the protective plate 5
Has a low strength and is malleable, so that the protective plate 5 feels clinging to the blade, the concrete cutter rises, and it becomes impossible to cut, and it becomes impossible to cut after that. The protection of the middle buried object 4 is achieved.
