摘要

PROBLEM TO BE SOLVED: To reduce time and efforts/cost for cleaning the inside of a drainage channel by preventing objects such as mud, sand or fallen leaves other than a fluid from flowing down into the drainage channel in a concrete secondary molding capable of draining the fluid into the drainage channel, to improve a strength of the concrete secondary molding itself and simultaneously to also improve a water catchment function.SOLUTION: The present invention relates to a concrete secondary molding which is provided on a drainage channel and capable of guiding a fluid on a road surface into the drainage channel. The concrete secondary molding is configured by integrally molding: a concrete secondary molding body 10 including an opening region for water catchment; and a filter part 22 which enables only the fluid to pass into a water catchment hole (opening region for water catchment) 18.SELECTED DRAWING: Figure 3
