天花板水电站大坝碾压混凝土工艺试验

Rolling Process Tests for the Roller Compacted Concrete Construction in Tianhuaban Hydropower Station

为了确定天花板水电站双曲拱坝碾压混凝土施工的相关参数,施工单位进行了工艺试验。通过试验,确定了大坝碾压混凝土的拌和工艺参数、碾压施工参数、层面处理技术措施和变态混凝土的施工工艺,验证了室内试验选定的混凝土配合比的可碾性和合理性,确保了工程质量。

In order to determine the construction parameters of RCC for Tianhuaban Double-curvature Arch Dam, the process tests are carried out by the construction unit, and the mixing parameters, rolling construction parameters and concrete surface treatment of RCC and abnormal concrete construction technology are determined. The process tests validate the mix proportion selected by laboratory tests is rolled and reasonable, and can guarantee the quality of construction.
