In response to the issue of compactness detection after bridge hollow slab grouting construction, this article studies the application of impact echo method in bridge grouting compactness detection based on the overhaul and renovation project of Shunhe Elevated Bridge in Jinan City. Through on-site experiments, the feasibility and effectiveness of the impact echo method in detecting the compactness of hollow slab grouting were analyzed. The experimental results indicate that by measuring the propagation speed and reflection characteristics of shock waves, the compactness of the grouting area can be evaluated, thereby improving the quality and efficiency of the grouting project. This study provides important reference and guidance for the compaction testing of hollow slab grouting in the renovation project of Shunhe Viaduct in Jinan City.
