Abstract: The transportable, foldable protective barrier, especially against high water, contains a series of supports of supporting elements articulately joined with one another, a number of parallel pipe rods for the joining of the supports as well as a number of reinforcement filling elements for the bridging of the gaps between the pipe rods. The supports are unfolded into bracing triangles and joined with the pipe rods which span a plane which are completed by grids or panels as reinforcement filling elements. Over the supports and the reinforcement filling elements panels are laid in the event of (a need for) high water protection.
