溪洛渡右岸地下电站,由180多条总长50多公里的特大型地下洞室群组成,是目前世界在建同类工程中最大的地下电站。其主要建筑物由发电厂房、主变室、尾水调压室“三大洞室”和引水系统、尾水洞灌排系统、通风系统等构成。主要实物工程量:石方洞挖345万立方米,混凝土浇筑149万立方米,钢筋制安9.8万吨,喷混凝土6.1万立方米,锚杆23.5万根,金属结构制安2.8万吨。其厂房内设计安装9台77万千瓦水轮发电机组,是目前世界上最大的地下厂房。工程于2006年5月开工,计划于2013年10月31日完工。工程具有规模宏大,结构复杂,通风布置困难,施工强度大且持续时间长、技术含量高、质量要求高等特点。
The underground power station on the right bank of Xiluodu consists of more than 180 extra large underground caverns more than 50 kilometers in length and is the largest underground power station under construction in the world at present. The main building consists of powerhouse, main transformer room, tail water surge chamber “three caverns ” and diversion system, tailrace irrigation system, ventilation system. The main amount of physical engineering: stone cubic hole 3.45 million cubic meters, 1.49 million cubic meters of concrete pouring, steel system of 98,000 tons, 61,000 cubic meters of sprayed concrete, bolt 235,000, metal structure system security 28,000 tons. Its plant design and installation of 9 sets of 770,000 kilowatts hydro-generating units, is currently the world’s largest underground plant. The project started in May 2006 and is scheduled to be completed on October 31, 2013. The project has the characteristics of large scale, complex structure, difficult ventilation layout, large construction intensity and long duration, high technical content and high quality requirements.
