SIDEWALK ROADWAY BOUNDARY BLOCK, AND SIDEWALK ROADWAY BOUNDARY DRAINAGE STRUCTURE

摘要

PPROBLEM TO BE SOLVED: To enhance water catchment performance to hardly generate a puddle even in heavy rain, in a sidewalk roadway boundary of a drive-in part, and to provide a barrier-free structure. PSOLUTION: A ditch is provided over a longitudinal-directional full length on an upper face of a sidewalk roadway boundary block in the drive-in part, a drainage ditch is provided over a longitudinal-directional full length on a bottom face, and a water flow hole is provided to be communicated with the drainage ditch from the bottom part of the ditch. The water catchment performance is enhanced by the ditch to hardly generate the puddle. The superior barrier-free structure is provided because water can be caught even without a step required conventionally. PCOPYRIGHT: (C)2011,JPO&INPIT
