Abstract: In order to study the feasibility and applicability of the impact echo method in the quality inspection of sleeve grouting, theoretical analysis and experimental research were carried out on the impact echo method. The results show that the impact echo method can be well applied to the detection of sleeve grouting compactness. Through the verification of the actual project, it is further confirmed that the impact echo method has a good application prospect in the detection of sleeve grouting. It is found in experiments and practical projects that the diameter, buried depth and boundary of the sleeve are easy to affect the detection results. An artificial intelligence (AI) aided detection method is proposed to optimize the above effects to improve the defect detection rate.
