“云端电站”建设忙

Core Viewpoint - The construction of the Yebatang Hydropower Station, the highest arch dam under construction in China, is progressing rapidly with a focus on ensuring quality and efficiency in extreme cold and high-altitude conditions [1][2] Group 1: Construction Progress - The Yebatang Hydropower Station is located at an altitude of nearly 3000 meters, with 1544 workers engaged in 24-hour construction to ensure the dam's completion and full operational capacity this year [1] - The dam has a maximum height of 217 meters, and workers face challenging conditions, including climbing over 200 meters daily to reach the site [1] Group 2: Technical Achievements - The construction team has developed a comprehensive "thermal protection" system to ensure seamless concrete pouring in extreme cold, addressing a significant global challenge in dam construction [2] - Last year, the team successfully poured 830,000 cubic meters of concrete, with 21 dam sections already completed, and achieved a world record by extracting a 38.1-meter-long complete concrete core sample [2] - As of now, there have been no temperature cracks in the dam, indicating that China's high-altitude arch dam construction technology has reached an internationally leading level [2]
