The examination of grouting effect has always been a weak link of grouting technology. This paper, based on the high-pressure grouting test of 7# construction tunnel in Tianhuangping Pumped Storage Power, comprehensively evaluates the grouting effect with the combining application of the comparison of drilling water flow, water pressurizing experiment, the comparative method of cement consumption and core-drilling method, to provide reference for grouting construction of similar projects in the future.
