Einsatz von technischen Textilien für den mobilen Hochwasserschutz

Mobile flood protection by use of technical textiles

The use of technical textiles for mobile flood protection is excel, especially if there is a short warning time in case of emergency flood events. This paper describes the transmission of textile building construction basics (textile roofs of stadiums and swimming pools) to the development of water-filled protection systems as an alternative to sand bag systems. It is shown that the investigations of material behavior of coated fabrics and the typical approach of membrane structures in architecture, such as form-finding, structural analysis and cutting pattern can be used to develop mobile flood protection systems. The following article manifests how this methodological approach is a suitable tool for the design of two selected flood control systems and is adapted to the specific requirements. The requirements and the selection of applicable materials, technical textiles in particular, are discussed. It describes the form finding of membrane shells under hydrostatic stress and illustrates in detail a static analysis of such a system. The procedure of the simulation of such problems by means of a supporting structure planning computer program will be presented by expanding the boundary conditions with the use of additional tools. The correctness of the procedure is ensured by experimental verification of the simulation results.
