Putkinskaya Hydroelectric Power Plant
Geosurvey of rock foundation area at Putkinskaya Hydroelectric Power Plant
Goals & Problems
The project aims to investigate the surface of the rocky terrain adjacent to the powerhouse of the Putkinskaya Hydroelectric Power Plant (HPP). The primary goal is to uncover the reasons behind uncontrolled water drainage from the upper reservoir to the lower reservoir along the exterior wall of the powerhouse. The focus is on understanding the heightened fissure zone, saturated with moisture, acting as an "underground rocky conduit."
Result
The project's findings reveal insights into the geological complexities, particularly the increased fissure zone (1) functioning as an "underground rocky conduit." Water from the upper reservoir, supported by the water base, drains through fractures and contact zones in the rocky structure, leading to uncontrolled discharge into the lower reservoir along the exterior wall of the powerhouse. This understanding provides a comprehensive view of the factors contributing to the undesired water flow.
Value for client
The project delivers immense value to the client by uncovering the root causes of uncontrolled water drainage. The detailed analysis of the fractured zone and water support mechanisms provides essential information for implementing targeted solutions. With this understanding, the client can develop effective strategies to mitigate the uncontrolled flow, ensuring the stability and operational efficiency of the Putkinskaya HPP's cascading system within the Karelian branch of OAO "TGK-1" in the city of Kem.
