Abstract

The damped vibration method is a method for detecting the grouting compaction of sleeves with embedded damping vibration sensors. The damping vibration sensor should be inserted into the grouting outlet as deep as possible before grouting, and testing can begin in 5~10 minutes after finishing grouting. On-site testings indicate: to ensure the compaction degree for the connected cavity grouting, the pressure time should be extended by 10~15 seconds before plugging the connected cavity grouting inlet, and the connected cavity grouting inlet should be plugged and fastened at the same time when the grouting pipe is pulled out; when the sleeves are judged to be not compacted through the damped vibration method, supplementary grouting from the initial connected cavity grouting inlet is the first choice.
