Test on Detection of Grouting Compactness of Grout Sleeve by Impact-echo Method

  • 摘要: 采用冲击回波法对不同类型和不同灌浆密实度的钢筋套筒试件进行了检测试验,结果表明:对于套筒居中布置的试件,无论有、无分布钢筋的影响,冲击回波法均能对其密实度进行定性判断,但定量结果与实际情况存在一定误差:对于钢筋套筒双排布置的试件,测试结果尚难以定性判断钢筋套筒的灌浆区和非灌浆区。总体而言,冲击回波法测试套筒灌浆密实度具有一定的可行性,但尚应在测试方式、分析方法等方面开展进一步的工作,以提高检测的精度和可靠性。
    Abstract: A series of experiments on grout sleeve specimens with different types and different grouting compactness were carried out based on impact-echo method. Test results show that the impact-echo method is able to give a good qualitative judgment for specimens with the steel sleeve in the middle, with or without reinforced bars, but there are some errors in the quantitative analysis between the test result and the actual situation. For specimens with grout sleeve double row arrangement, it is difficult to distinguish the grouting zone and the non-grouting zone based on the test results. Overall, the impact-echo method is feasible to detect the grouting compactness of grout sleeve to some extent, but some further research on the testing and analysis method is still needed for its accuracy and reliability to be improved.
