System for the Double-Sealed Connection of Waterproofing Panels for Hydraulic Works

A system for the double-sealed connection of waterproofing panels for lining surfaces of hydraulic works, such as dams, canals, water basins and the like. The system includes a central connection band, made of elastically flexible material and resistant to stress and perforation, whose longitudinal edges are superimposed to the longitudinal edges of continuous waterproofing panels; the system further includes a bottom locking element, an upper locking element superimposable to the previous one, and at least an intermediate sealing gasket, which extend along longitudinal edges of the connection band superimposed to the longitudinal edges of contiguous waterproofing panels; the bottom locking element and the upper locking element include a plurality of axially aligned rectangular compression plates connected by flexible hinges to allow the locking elements to freely adapt against planar and/or irregular surfaces of the surface of the specific hydraulic work to be waterproofed.
