The fullness degree of sleeve grouting in prefabricated buildings directly affects structural integrity and durability. Achieving accurate, rapid, and non-destructive testing remains a critical research focus. This study analyzes existing ultrasonic detection methods' limitations in signal attenuation and result instability, proposing an optimized detection approach for sleeve grouting fullness. Through signal feature extraction and propagation path adjustment, the method enhances detection sensitivity and stability. Results demonstrate its effectiveness in identifying grouting defect locations and severity levels, providing a reliable quality control method for prefabricated buildings with significant application potential.
