Abstract (en)
The invention concerns a drainage channel (101) adapted to conduct drainage water towards a drain, including a concave shell form (103) with sidewalls. The drainage channel is provided with a bottom ditch (107) at its bottom part. This bottom ditch is smaller than the drainage channel, and thereby less drain water is required in order to conduct the drain water towards a drain. Even small amounts of drain water can now be conducted towards a drain whereby it is avoided that water stands still in the channels.
