Core Viewpoint - The successful impoundment of the Dadu River Jinchuan Hydropower Station marks a significant step towards its commissioning, with the potential to replace approximately one million tons of coal consumption annually, contributing to a reduction in carbon emissions and optimization of China's energy structure [1][5]. Group 1: Project Overview - The Jinchuan Hydropower Station, located in Aba Prefecture, Sichuan Province, is the sixth hydropower station in the Dadu River's 28-level planning scheme, with a total installed capacity of 860 megawatts [1]. - The construction faced significant challenges due to complex geological conditions, being the highest rockfill dam in a deep cover area in China, with a construction difficulty level considered the highest domestically [1]. Group 2: Environmental and Technological Innovations - The project includes Asia's longest ecological fishway, designed to protect migratory fish species in the Dadu River, demonstrating a commitment to ecological preservation [3]. - The Jinchuan Hydropower Station has established China's first fully domestic three-dimensional digital modeling standard system for hydropower projects, enhancing geological analysis, construction simulation, and safety management [3]. Group 3: Economic and Environmental Impact - Upon completion, the Jinchuan Hydropower Station is expected to generate an average annual electricity output of approximately 3.5 billion kilowatt-hours, significantly contributing to reducing carbon emissions by about one million tons per year [5].

Core Viewpoint - The construction industry in Zhejiang is actively progressing during the National Day holiday, with thousands of workers dedicated to various infrastructure projects, showcasing their commitment to enhancing regional connectivity and economic development [1][5]. Group 1: Intelligent Construction - The Zhejiang Transportation Group's Ruicang Expressway project employs intelligent construction techniques, with over 910 workers focused on completing the road surface by October, aiming for operational readiness by year-end [2]. - Advanced machinery, such as three-arm rock drilling rigs and smart anchoring machines, is utilized in the construction of tunnels, significantly improving efficiency and safety [2]. Group 2: Project Milestones - At the Yongjinqu Expressway's construction site, over 1,000 workers are engaged in the critical task of beam installation for the Wuyi River Bridge, emphasizing the urgency to meet annual construction targets [3]. - The construction of 17 bridges and 3 tunnels in the Quzhou section is progressing, with a focus on achieving high-quality standards through meticulous parameter monitoring [4]. Group 3: Coastal Project Significance - The Ningbo Phase III project of the Hangzhou-Ningbo Railway involves 1,500 workers and is crucial for enhancing the coastal transportation network, with the main tower of the bridge reaching 200 meters [5]. - The ongoing construction activities are supported by a robust safety management system, ensuring the well-being of workers during the busy holiday period [5].
