Vinci has filed a patent for a system that allows for the double-sealed connection of waterproofing panels used in hydraulic works such as dams and canals. The system includes a central connection band, locking elements, and sealing gaskets to ensure a secure and watertight connection. The locking elements consist of modular compression plates connected by flexible hinges, allowing them to adapt to various surfaces.

A sealed connection system for waterproofing lining panels
A recently filed patent (Publication Number: US20230304247A1) describes a sealed connection system for waterproofing lining panels used in hydraulic works. The system includes elongated locking elements, an intermediate sealing gasket, and a central waterproofing connection band. The central connection band is made of flexible material with high resistance to stress and perforation. It is connected to the waterproofing panels using bottom and upper elongated locking elements and at least one sealing gasket.
The locking elements consist of modular compression plates that are axially aligned. They are connected together by flexible hinges. A disengageable connecting member is provided between each modular compression plate of the bottom locking element and the corresponding modular compression plate of the upper locking element. The sealing gasket is interposed between the modular compression plates of the upper locking element and the longitudinal edges of the waterproofing panels and the central connection band.
The system also includes anchoring elements for securing the central connection band to the wall of the hydraulic work. The lower modular plates of the locking elements have pointed elements that partially penetrate into the longitudinal edge of the central connection band. The connecting member can be a threaded pin or a bolt passing through aligned holes in the modular compression plates.
The dimensions of the various components of the system are specified in the patent. The central connection band has a width between 200 mm and 600 mm and a thickness between 3 mm and 20 mm. The compression plates have a length between 100 mm and 250 mm, a width between 30 mm and 100 mm, and a thickness between 2 mm and 10 mm. The sealing gasket has a width between 30 mm and 100 mm and a thickness between 3 mm and 18 mm. The compression plates of the locking elements are spaced apart by a gap with a width between 1 mm and 5 mm.
Additional features of the system include the use of a double-faced adhesive tape between the longitudinal edges of the waterproofing panels and the connection band, a plate for continuity of compression between the compression plates of the upper locking element and the sealing gasket, and the option to use different materials for the connection band (rubber, reinforced rubber, polymeric material, metal) and the compression plates (steel, synthetic resin, synthetic resin with glass fibers, synthetic resin with carbon fibers).
Overall, this patented connection system provides a secure and watertight seal between waterproofing lining panels used in hydraulic works. The use of modular compression plates and flexible hinges allows for easy installation and maintenance of the system.
