3 Initial Situation Sedimentation in drain pipes A plain surface to allow a continuous media transport Deposits and incrustations can be stated, caused by low transport speed or discontinuous use of the drain source: IKT Necessity for cleaning after some time Better solution Prevention of sedimentation 3

4 Initial Situation Basic idea: Change laminar flow -> turbulent flow lengthwise vessels Insights from bionics cross vessels wing cells Insects wing Plant Quelle: IAB Weimar 4

5 Construction of sewer A seamless woven fabric tube made of polyester / glass yarns With a coating made of PU or PE Glued permanently with the drains inside. drain glue seamless fabric impenetrable coating source: Karl Weiss Technologies 5

6 Goal of the project Development of a drain pipe inliner with a defined structured inner surface To change laminar flow -> turbulent flow Made with textile technology Use of standardized and glass fiber materials Proof of effect with several structures to the transport of solid matters in laboratory and filed tests 6
