The invention relates to a corrugated plastic drain board. The corrugated plastic drain board is composed of a plastic core veneer and water-permeable nonwoven cloths combined on the front and reverse sides of the plastic core veneer in an ironing manner; the corrugated plastic drain board is characterized in that the shape of a carrying surface, perpendicular to the length direction, of the plastic core veneer is a shape of a plurality of semicircular arcs in corrugated connection with each other, and the radius of each semicircular arc is within the range of 1.25mm to 1.5mm. According to the corrugated plastic drain board, the shape of the carrying surface, perpendicular to the length direction, of the plastic core veneer is formed into the shape of a plurality of semicircular arcs in corrugated connection with each other, thereby circular-arc-shaped drain channels on the front and reverse sides of the plastic core veneer are formed; besides, the radius of each semicircular arc is within the range of 1.25mm to 1.5mm, and the flow passage area of each drain channel thus can be increased by more than two times and a material for manufacturing the plastic core veneer is also reduced by more than one half; meanwhile, the water-permeable nonwoven cloths on the front and reverse sides are combined on the bottom and top surfaces of the arcs in the ironing manner, thereby achieving a shape stabilizing effect. The corrugated plastic drain board has the advantages of reasonable design, simple mold making, large flow passage area and low raw material consumption.
