Zusammenfassung:PROBLEM TO BE SOLVED: To prevent the breakage of a board drain and a drop in the water permeability of the same resulting from the consolidation settlement of the board drain. SOLUTION: The board drain 1 includes a belt-like core 2 having a plurality of groove stripes 21 and 21a formed on its surface to extend longitudinally, and a sheet-like filter 3 which is joined to the surface of the core 2 to cover openings of the groove stripes 21 and 21a to form water-permeating channels 4 between the filter 3 and the openings. The core 2 is made of a resin containing a starch-based material and has a hydrophilic group. COPYRIGHT: (C)2010,JPO&INPIT
