地下输水管道的声波检漏技术

Acoustic Wave Leak Detection Technology of Underground Pipelines

文章介绍了声波检漏技术的原理、方法和程序。听音杆、检漏仪和相关仪等设备的优化使用,加之合理的检漏程序,提高了地下输水管道漏点检测准确率。声波检漏技术作为一项新技术,在国内的漏水检测中突显了其优势,其检漏准确率可达80%,漏点定位误差小于正负1.0 m。

The fundamentals, methods and programs of acoustic wave detection technology are described. The optimal application of sound pole, leak detector and correlator supported by leak detection program have improved the accuracy of leak detection of under - ground water pipelines. The acoustic wave leak detection technology, a new technology with 80% of accuracy in leak detection and less than 1m （ plus or minus） in location error, has shown its advantages in water leak detection.
