Core Points - The article discusses the progress of the Yinhang-Jiwei project, a significant water conservancy project in China, which has successfully completed the main tunnel construction, moving closer to its goal of water delivery by 2026 [1][5]. Group 1: Project Overview - The Yinhang-Jiwei project consists of two main components: water diversion and distribution, with a total length of 983 kilometers for the Qinling water supply tunnel [5]. - The project aims to deliver 1.5 billion cubic meters of water annually to meet the needs of over 14 million people in 21 urban areas within Shaanxi province [7]. Group 2: Engineering Challenges - The construction faced significant challenges, including high temperatures (40°C) and humidity (90%) within the tunnels, as well as frequent rock bursts, with over 4,000 incidents recorded during the project [18]. - The project has implemented measures for environmental protection, including the establishment of fish breeding stations and ecological facilities to support local biodiversity [16]. Group 3: Impact and Benefits - The project has already demonstrated its importance by providing 120 million cubic meters of water during drought conditions in the spring and summer of 2023, ensuring water security for Xi'an [14]. - The first hydropower generator of the Huangjinxia Hydropower Station has been successfully connected to the grid, with an average annual power generation of 132.5 million kilowatt-hours [9].
