A climbing formwork system for mass concrete construction comprises a movable panel separating a filling volume from an external environment, a track extending along a longitudinal direction partially inside said filling volume with a sliding channel closed with respect to the filling volume and a longitudinal slit facing the external environment. In addition, the climbing formwork system comprises a climbing element positioned and slidingly inserted in the sliding channel having a connection portion projecting through the slit to be connected with a portion of the movable panel. Fastening elements are operatively connected between the connection portion of the climbing element and the movable panel in order to maintain the latter fixed to the climbing element in a union condition. Also, a subject of this patent application is a method for building a mass concrete construction.

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.
