Shuttering system for the construction of compact concrete dams. The system is used for constructing compacted concrete dams, forming a continuous system of shuttering faces (upstream, downstream and spillway), for compacted concrete dams, enabling the continuity of the production process and preventing the formation of cold joints. It includes a metal plate 1 fixed to a structure formed of lateral 7 and central 8 sections, whose structure supports a scaffold 10 with a safety rail 17 that is supplemented by another safety rail 16 provided on the upper part of the structure. The assembly that forms this structure, with the plate and the scaffold, is moveable in an upward and downward direction by means of a lifting device, which, having a hinge 22 and being joined to the structure, is guided in a vertical tube fastened into the mass of the layers of concrete. Other means of fastening formed of cables 13' and 14 are included and their corresponding anchorings 12, as well as bars 18 joined to the lateral sections 7 of the structure so that the workers can access the respective scaffold. <IMAGE>
