两河口抽蓄电站上库春节施工航拍。 2月22日，记者从雅砻江公司获悉，在海拔3000米的川西高原，作为全球在建规模最大、海拔最高的混 合式抽水蓄能电站，甘孜州雅江县的雅砻江两河口抽蓄电站迎来关键节点双突破：地下厂房开挖圆满完 成、下水库牙根一级水电站大坝开启首仓混凝土浇筑。两大工程节点的实现，为两河口"水风光储氢 算"清洁能源示范区2028年建成按下"加速键"，为国家首个水风光一体化基地2035年前全面建成投运奠 定坚实基础。 地下厂房开挖完成 迎来关键节点双突破 春节期间，超500名建设者坚守一线，抢抓枯水期施工"黄金窗口"，实行24小时轮班作业，投入使用首 台国产智能无人凿岩台车，实现"自动行走、精准定位、自动钻孔、多臂协同作业"，钻孔精度达厘米 级，并将数据实时传输到控制中心。这种"无人智能建造"模式，不仅让施工效率提升30%以上，更大幅 降低人工劳动强度与安全施工风险，助力电站厂房提前3个月开挖完成。 地下厂房开挖完成，标志着工程土建开挖阶段收官，建设转入机电设备安装阶段，为两河口"水风光储 氢算"清洁能源示范区2028年建成提供有力保障。电站建成后，预计每年可提供清洁电能14亿度，能满 足60万户家庭 ...

Core Insights - The construction of two world-class clean energy projects, the world's largest mixed pumped storage power station and the world's largest water-solar complementary project, is progressing rapidly in the Sichuan region, with thousands of workers actively involved during the Spring Festival [1][2]. Group 1: Two Rivers Pumped Storage Power Station - The project is currently at a critical phase of underground excavation, with over 500 workers engaged in key areas to prepare for concrete pouring and electromechanical installation after the holiday [2]. - The project faces significant challenges, including extreme cold, low oxygen levels, and ecological fragility, while also addressing a world-class technical challenge related to the stable operation of large-capacity pumped storage units [2]. - A rigorous safety and quality management system is in place, including a night shift inspection mechanism and precise blasting techniques to ensure safety during excavation [2]. Group 2: Kola Phase II Photovoltaic Project - Located at a higher altitude, the Kola Phase II project faces severe challenges such as extreme temperature fluctuations and frozen ground, impacting both personnel and equipment efficiency [3]. - A comprehensive concrete "warming package" has been implemented to ensure proper mixing and curing, alongside providing workers with necessary protective gear and emergency facilities [3]. - The project is expected to contribute approximately 1.9 billion kilowatt-hours of clean electricity annually upon completion, enhancing power supply reliability [3]. Group 3: Overall Progress of Clean Energy Projects - Multiple clean energy projects, including the Dawa Pumped Storage Power Station and Yagen First Hydropower Station, are advancing rapidly, with significant construction activities ongoing during the Spring Festival [4][5]. - The Yagen First Hydropower Station is at a peak construction phase, crucial for its scheduled commissioning in 2028, with over 600 workers engaged in various tasks [5]. - The integration of smart technologies, such as intelligent drilling rigs and unmanned compaction machines, is enhancing construction efficiency across the projects [5].
