Abstract (en)
[origin: WO8101580A1] An arrangement related to a drainage pipe (2) provided with inlet holes (3) for water, said holes (3) being positioned on the upper half of the drainage pipe (2) and the drainage pipe being fully or partly covered by a jacket or exterior plate (12). The lower edge or edges of the jacket lies or lie substantially on the same level as the lower edge portion of the drainage pipe. The jacket may possibly be smooth, whereas the drainage pipe (2) is corrugated. The water will then rise in the space between the jacket and the pipe, which space serves for deposition of possible particles, and thereafter will enter into the pipe through the holes. The arrangement may be used for simplified disposition of drainage without particular necessity for draining masses above the arrangement.
