In order to detect the grouting defects of the assembled building joints, this study uses ultrasonic testing methods to detect the grouting sleeves in six different defect conditions in the laboratory and the two-sided grouting and unfilled shear wall joints. The main ultrasonic sound velocity value detection index, research shows that: through the grouting sleeve ultrasonic detection sound velocity value analysis, ultrasonic testing can effectively detect the position of the grouting defect in the sleeve, there is a clear boundary line between the defect and the non-defect; And the eccentricity has an influence on the sound velocity value of the unfilled part, and the influence on the sound velocity value of the grouting part is not obvious; the ultrasonic sound velocity value and the amplitude detection result of the grouting sleeve of the field assembled shear wall joint are analyzed, and the unfilled sleeve shear wall test component is analyzed. The acoustic wave test results are around 1.0km/s-1.3km/s, and the acoustic wave test results of the grouting sleeve shear wall test members are around 2.0km/s-2.3km/s. The ultrasonic test wave of the ungrouted sleeve shear wall test component is tested. The amplitude result is about 24.3 dB - 30.0 dB, and the ultrasonic test wave amplitude value of the grouting sleeve shear wall test component is 40.3 dB - 44.5 dB. Around dB, the position of the grouting sleeve and the unfilled sleeve can be effectively discriminated by ultrasonically detecting the sound velocity value and the amplitude value.
