［摘要］套筒灌漿連接是其豎向預制構件最重要的連接方式，也是保證裝配整體式混凝土結構性能達到等同現澆的關鍵，需對其灌漿質量進行嚴格管控。國內外學者提出了許多針對套筒灌漿的質量檢測和整治技術。首先對各類套筒灌漿質量檢測方法的原理、特點與應用現狀進行了概括，并在綜合有效性、適用性和經濟性的基礎上對各類方法進行了比較與優選。對于套筒灌漿事中檢測和質量控制，建議采用預埋傳感器法；對于套筒灌漿事后檢測，建議采用鉆孔內窺鏡法，必要時可采用X射線數字成像法或預埋鋼絲拉拔法進行補充校核。然后，對套筒灌漿缺陷的評估與整治研究現狀進行了總結。對于檢測后存在套筒灌漿缺陷的結構，可采用補灌法恢復其結構性能。最后，對后續研究與工程應用進行了展望。

Abstract:The grouted sleeve connectors are the most important method for connection of vertical prefabricated components, which is the key to ensure the performance of assembled monolithic concrete structure to be equal to cast-in-situ structure. The grouting quality should be strictly controlled. A number of quality detection and repair techniques for sleeve grouting have been proposed by domestic and foreign scholars. Firstly, the principles, characteristics and application status about all the detection methods were summarized. Then the comparison and selection of all the methods were made based on combination of effectiveness, applicability and cost. In grouting process, it is recommended to use the embedded sensor method to detect the defect. After the grouting is completed, it is recommended to use the hole-drilling method combined with endoscopy to detect the defect. If necessary, additional check can be performed by X-ray digital radiography method or embedded steel wire drawing method. Then, the research status of evaluation and repair for sleeve grouting defects were summarized. For structures with sleeve grouting defects after detection, the structure performance can be restored by supplementary grouting. Finally, the future research direction and engineering application were prospected.
