Description

Technical Field

[0002] Grouting sleeve connection refers to using sleeves to connect the steel bars at both ends of prefabricated components. Self-compacting and slightly expanding grouting material is injected into the sleeve grouting hole, and a high-strength connection joint is formed after the grouting material solidifies and hardens. If the density of the grouting material in the sleeve is insufficient, the steel bars in the grouting sleeve will be pulled out and damaged under the load, seriously affecting the safety of the structure. Therefore, the density of the grouting sleeve slurry needs to be tested every time grouting is performed. The piezoelectric wave method has the advantages of low detection cost, good portability, and no damage to the sleeve and components. It has a wide range of application prospects in engineering construction.

[0003] In the verification test of the piezoelectric wave method, it was found that the arrangement of piezoelectric elements embedded in the grouting material is more conducive to improving the detection accuracy of the sleeve grouting fullness. However, the embedded arrangement of piezoelectric elements is difficult, the wires cannot reasonably extend from the sleeve and shear wall, the detection of grouting defect positions and volume values is random, and due to its own structural characteristics, it is easy to be damaged during the installation process. When the contact between the piezoelectric element and the grouting material is not good enough, the monitoring data may be inaccurate, thus affecting the reliability of the final test results.

[0004] Therefore, it is necessary to propose an intelligent rubber plug for a grouting sleeve to solve the above problems. Utility Model Content
