摘要

PROBLEM TO BE SOLVED: To provide a channel block capable of efficiently draining permeating water of a water-permeable pavement section. ;SOLUTION: A channel block 3 is constructed along the edge part of a water- permeable pavement section 2 in a state to link with a channel 5 thereof. The channel block 3 is equipped with a water receiving surface 7 of one upper angle part of a block main body 4 having the channel 5 therein. Drain outlets 16 linking with the channel 5 are provided to the water receiving surface 7 at required intervals in the direction of the length. Then, the lower end of an opening edge in an opening of the upper end of the drain outlet 16 is roughly fitted to the lower end edge of the water receiving surface 7.;COPYRIGHT: (C)1998,JPO
