Abstract: In view of the current lack of quality test of prestressed corrugated pipe grouting for concrete bridge, this paper proposed low-frequency sound wave vertical penetration method. By laboratory tests, this paper examined grouting slurry age(strength) of corrugated pipe, concrete age(strength) of bridge beam and other factors on the effect of propagation velocity of the test wave. And based on propagation mechanism of sound wave in the medium, grouting compactness of the corrugated pipe and the relationship between the wave propagation parameters model was constructed. It indicated that the model was in good agreement with the test results better by the experimental beam testing.
