Abstract
On the internal structures of hydraulic structures of a number of HPPs, water manifestations are noted, that is, the appearance of traces of moisture outside the culvert, which can lead to a change in the operational condition of the structure or damage to expensive equipment. At the same time, the processes that cause such manifestations are extremely diverse. The formation of filtration foci can be due to a gradual change in the condition of block joints; degradation of cement stone due to corrosion or under the influence of loads exceeding the design ones; increase in filtration costs, as well as the features of the construction of structures. As an example of structures that are characterized by water manifestation, itis necessary to cite the Rybinsk and Uglich hydroelectric power plants, for which during the entire period of operation there is a water manifestation near the turbine shafts of hydroelectric units and on the surfaces of the barrels of spiral chambers. In 2019-2021, in order to establish the causes of these phenomena, specialists of the branch of JSC Institute Hydroproject-NIIES conducted a survey of the concrete structures of the Uglich and Rybinsk hydroelectric power plants, during which it was found that the main causes of water in the areas under consideration for each station are largely similar, but not identical.
