DRAINAGE SYSTEM, EXECUTION METHOD THEREFOR, AND BLOCK MEMBER

摘要

PROBLEM TO BE SOLVED: To recycle a used glass bottle for being disposed of as a discarded material, by using a foam glass material for a drainage system, more excellent in water permeability than conventional infiltration facilities, and an execution method therefor. SOLUTION: In this drainage system, the periphery of a perforated pipe 1 or that of a side ditch body 8, in which at least a side surface has a permeable structure, is filled with the foam glass material 2 with a high percentage of voids, so that permeability can be enhance. Additionally, the discarded material of glass is effectively recycled as the foam glass material, so that the above purpose can be accomplished. COPYRIGHT: (C)2004,JPO
