摘要
三峡工程左厂 11～ 14号坝段电站进水口是重要的永久建筑物 ,其压力钢管直径为 12 4m ,是目前国内最大的压力钢管 .从易于调节的牵引式钢模台车、弧形角钢样架控制过流面成型质量、操作简便的“线出浆”灌浆系统、工效高质量稳定的钢筋热墩粗直螺纹连接新技术及易振捣密实的高流态混凝土等方面介绍了电站进水口的施工技术 ,其中钢筋热墩粗直螺纹连接新技术为国内大型水利工程施工中首次采用 .
The inlet of the hydropower station at the left No. 11～14 dam sections is an important permanent structure, the penstock diameter being 12 4?m, the largest in China. Some techniques are introduced for the inlet construction, including an adjustable track steel mould jack plane, arc angle steel shelves used for control of the quality of overflowing surface, a line grouting system easy to be operated, efficient and quality stable hot thick straight thread connection technique, and high flow state concrete easy to be vibrated. Of the above techniques, the efficient and quality stable hot thick straight thread connection technique was applied to large hydro projects in China for the first time.
