SIDEWALK-DRIVEWAY BOUNDARY BLOCK AND DRAINAGE STRUCTURE OF PERMEABLE PAVEMENT

摘要

PROBLEM TO BE SOLVED: To provide a sidewalk-driveway boundary block quickly and economically coping with the change of ridge shape or pattern, having excellent appearance after construction, capable of quickly draining water on the road surface of permeable pavement and having excellent mutual positioning work efficiency of blocks during construction regarding the sidewalk-driveway boundary block of L-shaped or inverted T-shaped cross section provided with a base part buried under the road surface and forming a boundary of a sidewalk or a median strip and a driveway.;SOLUTION: In the sidewalk-driveway boundary block with a base provided with a drain way in a base part and structured not to expose a base part upper face to the ground surface, the base part and a ridge part can be separated into a base block and a ridge block and individually molded. The ridge blocks of various shape can be joined in good attitude on the base blocks and integrated, and a slight installation error of the base block can be corrected at a joint part between the base block and ridge block.;COPYRIGHT: (C)2005,JPO&NCIPI
