摘要： Provided is an apparatus and method for detecting grout compactness in grouted splice sleeve, the apparatus comprises a probe assembly, which comprises at least one of capacitive probe and piezoelectric sensor and is arranged inside the grouted splice sleeve to detect parameters of the sleeve during grouting and curing and a detector, which comprises at least an analysis module that is connected with the probe assembly to obtain the detected parameters and carry out calculation and analysis for the parameters. The probe assembly is arranged inside the grouted splice sleeve and forms a loop with the detector during grouting, such that during the process of grouting, the detected parameters will be changed as the surrounding dielectric changes, therefore, the detector may determine in real time whether the grouted splice sleeve is fully grouted by calculating and analyzing the detected parameters, which achieves a faster and easier grout compactness detection.
