日前,由中铁隧道集团施工的台山核电站1号机组取水隧洞安全贯通,顺利实现了大襟岛与陆域侧的互联互通。台山核电站取水隧洞长4 330.6 m,埋深11～38 m,开挖直径9.03 m,连续下坡,隧洞两端高差22 m,由于存在“三高”(科技含量高、施工难度高、安全风险高),被业界誉为“中国越海盾构第一隧”。
Recently, the water intake tunnel of Unit 1 of Taishan Nuclear Power Station constructed by China Railway Tunnel Group was safe and successfully interconnected with each other on the Dajin Island and land areas. The Taishan Nuclear Power Station’s water intake tunnel is 4 330.6 m in length and 11 to 38 m in depth with a diameter of 9.03 m and a continuous descending slope. The height difference between the two ends of the tunnel is 22 m. Due to the high technical content and high construction difficulty , High security risk), was praised as “the first tunnel of China’s cross-sea shield” by the industry.
