16HFV and 34HFV PTC vibrodrivers in Rhinau, France, for driving of HEA220 piles and GU12-13-18-22 sheetpiles in the Rhin river, for the construction of fish passes.
Two fish passes are being constructed at the Rhinau and Marckolsheim hydroelectric dams, which will be amongst the biggest in Europe. Each structure will consist of a series of pools on hundreds of meters for the fish to cross, like stairs. The objective is to make way again for migratory fishes, and boost fish biodiversity in the area.
Use of the vibrodrivers 100% underwater, and use of a mobile crane (120t).
