摘要 <P>PROBLEM TO BE SOLVED: To inexpensively provide a drainage channel for road surface, which has high water collecting efficiency, flexibly copes with various usage modes, and has fewer components and high strength, while taking advantage of using standardized steel pipe products as conventionally. <P>SOLUTION: A drainage channel 10 for road surface according to the present invention is the drainage channel for road surface, in which a standardized steel pipe 1 is used for the channel. Water-passing holes 4 are provided in the upper face of the standardized steel pipe 1; with regard to the side face thereof, water-passing holes are provided in some cases but not in another cases. A water-guide plate 2 is prepared as an auxiliary water-guide member structured so as to efficiently guide water into the steel pipe 1 through the water-passing holes 4 in the upper face thereof. <P>COPYRIGHT: (C)2012,JPO&INPIT
