Road incidental facilities and methods for constructing road incidental facilities

摘要

PPROBLEM TO BE SOLVED: To provide road ancillary equipment requiring no working of a road surface, and strongly fixable to the road surface by using an adhesive. PSOLUTION: The adhesive flows in from an opening part having an inlet narrowed more than the inmost part, and hardens to prevent slipping-out. Fixing force to the road surface is not adhesive strength of the adhesive and a road ancillary equipment surface, and relates to shearing force of the adhesive, so that further higher fixing force is obtained than only arranging a recess/ projection. Since the high fixing force is obtained, there is no need to use a leg part and an anchor nut, and thus, working such as boring a pore in the roar surface is not required. PCOPYRIGHT: (C)2004,JPO
