摘要
大花水水电站拦河大坝为碾压混凝土双曲拱坝,最大坝高134.50 m。采用快速施工技术,创造了国内碾压混凝土连续浇筑上升33.5 m的记录。重点介绍了高速胶带机水平运输技术、缓降溜管垂直运输技术以及碾压混凝土仓面工艺。
The concrete placing pace of the 134.5 m high roller compacted concrete(RCC) arch dam of Dahuashui Hydropower Station is quickened by using the belt conveyor system with gently lowering pipe chutes;a new construction record of continuously concreting height 33.5 m is achieved.The details about concrete conveying and spreading are described.
