Abstract: Yangfanggou Hydropower Station is the first gigawatt hydropower station built under EPC mode in China. This paper mainly introduces the quality control measures of fair-faced concrete pouring in the construction of rock-bolted crane beam. Before the construction, the contractor strictly implements the "examplary construction system", making the construction techniques fixed, thus the quality control points of the fair-faced concrete construction were defined. Then the strict quality control measure and the guarantee measure were formulated, which can improved the concrete construction craft to guarantee the quality of fair-faced concrete pouring. Relevant experience can be used for reference in similar projects.

Key words: fair-faced concrete, rock-bolted crane beam, construction process, quality control, examplary construction system, Yangfanggou Hydropower Station
