摘要:
地下管道在长距离输水工程中应用广泛，输水管道的渗漏安全监控及预警已成为行业研究的重点。针对这一重大行业需求，以嘉兴市域外配水工程为依托，引入分布式光纤传感技术和准分布式水声侦听技术，搭建了实时在线渗漏监测系统。应用结果表明，采用这两种监测技术可以精准定位30 s内渗漏水量>20 L的渗漏点，定位误差在10 m之内。
Abstract:
-Underground pipeline has been extensively utilized for long-distance water transmission, and the safety monitoring and early warning of water transmission pipeline leakage has been concerned. Based on the extraterritorial water distribution project in Jiaxing, a real-time online leakage monitoring system is built by introducing distributed optical fiber sensing and quasi-distributed underwater acoustic detection methods. The application results demonstrate that these two monitoring techniques can accurately located leakage points with a volume exceeding 20 L within 30 seconds, and the positioning error is no more than 10 m.
