| titleOfInvention | Tube sheet wall post-grouting body core-pulling inspection device and inspection method thereof |
| abstract | The device comprises a drill rod and an ejector rod, wherein the drill rod is of a hollow structure with two open ends, one end of the drill rod is a sharp drilling end, the other end of the drill rod is an ejector rod built-in end, and the ejector rod is inserted into the drill rod from the ejector rod built-in end and can move back and forth in the drill rod. When the device is used for inspection, the steps of duct piece wall post-grouting, drill rod jacking, core sample extraction and core sample ejection are sequentially carried out, so that the device is simple and convenient. The method has the advantages of low cost, simple and convenient operation, timely, fast, simple and effective inspection of the quality of the segment grouting body, effective guarantee of the shield construction quality, and avoidance of the risks of settlement and collapse of the ground construction structure caused by the quality problem of the grouting body. |
