基于声振法的隧道二衬脱空检测仪器设计研究

Design and Study of the Tunnel Secondary Liner Void Detection Instrument Based on Acoustic-vibration Method

针对声振法在隧道二衬脱空检测中存在的不足,提出了一种新型的隧道二衬脱空检测仪器,旨在实现隧道二衬脱空声振法检测的规范化,降低检测成本和人工高空作业带来的风险,并在隧道二次脱空声振法检测中得到更准确的结果。

For the shortcomings of the acoustic-vibration method in the tunnel secondary liner void detection, a new type of the acoustic-vibration detection instrument has been developed, aiming to realize the standardization of the acoustic-vibration detection of tunnel secondary liner void, reduce the cost of detection and the risk of artificial high altitude operation and obtain more accurate results in tunnel secondary liner void detection based on acoustic-vibration method.
