Document Type and Number:
Japanese Patent JP6964643
Kind Code:
B2
Abstract:
To prevent a conduit line from being cut, by reducing a cutting speed and changing cutter cooling water into muddy black when cutting is applied to a protective plate in the state in which the protective state is not exposed on a road surface, and further, to remarkably reduce a manufacture cost in comparison with conventional protective plates.SOLUTION: A protective plate installation structure 100 has a configuration in which, in the case of a road condition that a standard soil cover dimension to a power measuring box, etc., 15 cannot be secured in an asphalt pavement road 10, a protective plate 1 is provided while being positioned at an upper side of each power measuring box, etc., 15 and a top face of the protective plate 1 is covered in an asphalt layer 13. The protective plate 1 is made of concrete in which a reinforcement frame 2 is embedded at a proximate position of an outer peripheral surface, smaller than a thickness of the asphalt layer 13, installed while matching a bottom face of the protective plate 1 with a bottom face of the asphalt layer 13, and positioned in the state in which a size of a planar view shape is expanded to both sides in a road width direction with respect to the power measuring box, etc., 15 and an end shape in a road direction in a planar view is non-rectangular.SELECTED DRAWING: Figure 1
