System for the double-sealed connection of waterproofing panels for hydraulic works

A sealed connection system between waterproofing panels suitable for lining a wall of hydraulic works, comprising elongated locking elements for locking the waterproofing panels

• a central waterproofing connection band between the contiguous waterproofing panels, the central waterproof connection band being made of elastically flexible or yieldable material, the central waterproofing connection band having features of resistance to stress and perforation that are comparatively greater than features of resistance to stress and perforation d perforation of the waterproofing panels;
• the elongated locking elements including a bottom elongated locking element and an upper elongated locking element for locking longitudinal edges of the central waterproofing connection band to longitudinal edges of the waterproofing panels,
• at least one intermediate sealing gasket, that extends along the longitudinal edges of the central waterproofing connection band;
• in which each of the elongated locking elements includes a plurality of axially aligned modular compression plates;
• at least one disengageable connecting member between each modular compression plate of the bottom locking element and a corresponding modular compression plate of the upper locking element;
• and
• in which axially aligned contiguous modular compression plates of the upper and bottom locking elements are connected together by flexible hinges, each flexible hinge consisting of one of the longitudinal edges of the ventral waterproofing connection band, the flexible hinges making the elongated locking elements configured with a plurality of flexible joints which allow the entire connection system to fit a surface to be waterproofed, thus preventing the central waterproofing connection band from penetrating into slits or cracks of the surface.
