The Electromagnetic Characteristics of Steel Bars in Cement Pole and Their Effects on Circumferential Positioning

  • 摘要: 钢筋是水泥杆的骨架,其健康状况直接影响水泥杆的强度。分析了电磁探伤的原理,设计出用于测试水泥杆中钢筋分布的标样和试验系统。标样由PVC管、端盖和钢筋构成,试验系统由传感器单元、信号采集器和分析软件组成。通过试验,对钢筋周向分布变化的电磁信号进行了采集,数据分析了钢筋的电磁特性及对周向定位的影响。研究表明,采用电磁法在适当精度内对钢筋定位的影响较小,可用于水泥杆的质量检测。
    Abstract: Steel bars are key parts in cement pole, and their health status shall have effect on the safety of cement pole in use. The principle of electromagnetic testing was analyzed, and the testing sample and experiment system were designed according to the research purpose. The sample is composed of end cover, PVC pipe and steel bars, and the experiment system was designed by three parts, the sensor unit, the signal processing and the computer system which are used to measure the electromagnetic characteristics of circumferential distributions of cement pole. At last, the experimental scheme is designed to collect the electromagnetic characteristics and study in their effect on the steel bars circumferential positioning. The data showed that it had little effect on steel bars positioning under appropriate accuracy and it was a useful method for the quality evaluation of cement pole.
