国家“八五”科技攻关项目——装机三台、总容量7.5万kW、年平均发电量3.4亿kw·h的贵州普定水电站,坝体采用高掺粉煤灰干硬性混凝土、整体通仓薄层浇筑、全断面碾压连续上升的新技术施工,今年汛期前碾压完毕的3.6287万m~(?)混凝土,节省工程资金88.44万元。兴建普定水电站引人注目的最大特点,是我国首次采用碾压混凝土筑坝技术施工高拱坝,与传统的常态混凝土筑坝方法相比,具有水泥用量少(每立方碾压混凝土少用水泥161.7kg)、施工速度快、工程造
National “Eighth Five-Year” scientific and technological project - installed three, with a total capacity of 75,000 kW, the average annual generating capacity of 340 million kw · h Puding Hydropower Station, dam with high dry fly ash mixed with hard concrete, the whole warehouse Thin-layer pouring, rolling the whole section of the continuous rise of new technology construction, completed before the flood season this year, 3628700 m ~ (?) Concrete, saving 884,400 yuan of engineering funds. The most notable characteristic of constructing Pudding Hydropower Station is that it is the first time that China uses RCC dam construction to construct the high arch dam. Compared with the traditional normal concrete damming method, it has less cement usage (less use of cubic meters of RCC Cement 161.7kg), construction speed, engineering
