Abstract
The present invention called reversible flexible wall dams deals with cable supported, cross reinforced, flexible membranes dams designed to replace the massive conventional concrete dams in the same way as the suspended bridges where designed to replace the massive concrete bridges, using cable supported, high tensile strings, cross reinforced, flexible membranes as water barriers with their lower ends tightly and firmly connected to the water bed and with their upper edges supported vertically with horizontal cables supported at intervals by means of vertical ties connected to pillars erected at distances all along the dam, the flexible membrane barriers are supported at their back, at different elevations, with horizontal cable grids supported vertically by means of ties connected to the said pillars, the cables of said cable grids are anchored upstream to the water bed, with anchoring ties connecting said cables, through water tight connections across the flexible membrane, to the water bed, the flexible membranes are connected to the water bed by means of curvaceous channels built through the concrete base all along the dam with the lower edges of the flexible membranes being inserted through said curvaceous channel and squeezed inside by means of wedging wooden blocks or the like interlocking to squeeze said flexible membranes inside the concrete base ensuring a tight and firm connection between the flexible membrane and the concrete base, parallel spare curvaceous channels arc provided to allow the replacement of the flexible membrane every 30 or 40 years if required, while keeping the old membrane in operation until the installation of the new membrane is completed, a thin vertical concrete wall is built below the concrete base to be used as a underground water barrier, the supporting pillars are built either of massive concrete pillars or by means of vertical and slanted piles driven at distances in the water bed and joined at different elevations with platforms tying each set of piles together, steel towers or the like are erected on top of said pillars, the towers capping the different pillars are joined together with steel cables to be used as railings for a traveling crane servicing the dam in its different operations, resulting in economic, light weight, flexible membrane dams for any height of water head, limited only by: a) The strength of the cross reinforcement of the flexible membranes and b) the strings of the wire cables supporting the flexible membranes.
