Innovative Solutions for the Construction and the Repair of Hydraulic Structures.

Abstract: Hydraulic structures underlie extraordinary conditions due to their prominent function and exposure. Thus, high demands have to be made both on construction and maintenance or repair of the structures, respectively. In order to fulfill these demands new and special technologies have to be developed that ensure an effective construction and guarantee to meet the planned service life of the building required by the owner. Against this background two innovative methods for both construction and repair of hydraulic concrete structures are presented in the present paper. The methods are based on modern concrete technology and enable to either build concrete dams in flowing water or perform concrete repair below the water level. Both methods were developed at the Institute of Concrete Structures and Building Materials at the Karlsruhe Institute of Technology (KIT), Germany and were applied in practice for construction of the Bribin underground hydropower plant in Indonesia and for repair of the river hydropower plant of Albbruck-Dogern in Germany.
