Baihetan Hydropower Station (underwater repair and maintenance)
2025-05-09
Project Name: Repair of the underwater base of the gate in the diversion tunnel of the Baihetan Hydropower Station
Materials Used: HK-UW-1 underwater epoxy resin concrete, MB-SXM underwater sealant
Results: Due to long-term high-flow operation, parts of the base of the gate in the Baihetan Hydropower Station's diversion tunnel experienced scouring. To ensure the safe operation of the gate, underwater repair was necessary. After evaluating various schemes, our company's HK-UW-1 underwater epoxy resin concrete was used for underwater construction and repair. This product is self-leveling, self-compacting, and vibration-free underwater; it exhibits rapid underwater strength gain, ultimately reaching over 90 MPa. After the repair, the gate was successfully lowered, and the diversion tunnel was successfully closed. This project was carried out simultaneously with the repair of the gate base in the diversion tunnel of the Wudongde Hydropower Station.
