Described are various embodiments for coupling devices for dock installations.

A tunnel system includes at least two adjacent tunnel lining systems and a sealing system. Moreover, the tunnel lining systems can include plural tunnel lining segments.

A module for implementing a protective barrier against liquid runoff and/or flooding comprising a retention member adapted to retain a liquid body on a front area located at a front side of the protective barrier, one or more sensors adapted to acquire at least one information about the module or about the liquid body, a relief valve, the relief valve being adapted to be actuated from a closed state to an open state according to the information acquired and provided by the sensor, and related system and method.

A method and a device for laying down and sealingly anchoring a waterproofing liner of a synthetic material, on a surface of a hydraulic work. The liner is fastened by a plurality of tensioning and anchoring assemblies, each including a lower and upper metal section bars configured with a raised part having side flat surfaces for sealingly clamping the liner, wherein the lower section bar has more anchoring holes at a plurality of axially spaced apart anchoring zones; the surface of the hydraulic work is previously marked by reference marks underlining the presence of possible obstacles such as reinforcement rods near the anchoring holes of the anchoring zones of the lower section bar; therefore the lower section bar is positioned by aligning the anchoring holes to the reference marks, anchoring the section bar to the hydraulic work by anchoring devices) at least one hole of the anchoring zones wherein there is no obstacle to the insertion of the anchoring devices in the hydraulic work. The waterproofing liner is laid down on the surface of the hydraulic work, and is sealingly anchored it between the lower section bars and the upper section bars of the tensioning assemblies.
