普定水电站大坝高75m,混凝土量15.05万 m~3,其中碾压混凝土10.7万 m~3,装机三台,总容量7.5万 kw,年均发电量3.4亿 kw·h。电站坝体采用高掺粉煤灰干硬性混凝土、整体通仑薄层浇筑、全断面碾压连续上升新工艺,今年汛期前碾压完毕的3.6287万 m~3混凝土,节约投资88万余元。这是我国首次采用碾压混凝土筑坝技术修建高拱坝,与传统的常态混凝土筑坝方法相比,每立米混凝土少用水泥161.7kg,具有施工快、造价低、温控简单,设备通用性强等优点。为今后
The dam of Puding Hydropower Station is 75m high and the concrete volume is 150,500m 3, of which 107,000m 3 are roller compacted concrete and installed in three units with a total capacity of 75,000kw and annual generating capacity of 340 million kw · h. The dam of the power station adopts high-fly ash dry hard concrete, with the whole Tonglun thin-layer pouring and the whole section rolling continuous rising new technology. Before the flood season this year, it has completed 36,287 thousand m ~ 3 of concrete that has been crushed, saving an investment of 88,000 yuan. This is the first time that China uses RCC dam construction to construct high arch dam. Compared with the traditional normal concrete dam construction method, the cement used per cubic meter is less 161.7kg, which has the advantages of quick construction, low cost, simple temperature control and universal equipment Strong and so on. For the future
