- Abstract:
- Most urban pipes are deeply buried underground, and various diseases may occur during long-term operation. Traditional detection methods can not obtain the status of the pipeline in real-time, so it is impossible to predict the possible hazards of the pipeline and take preventive measures. Distributed optical fiber sensing technology with the characteristics of distributed structure, long-distance and real-time monitoring, is suitable for underground pipeline monitoring. Combined with the second sewage pipeline project in Nanjing, the distributed optical fiber sensing technology was used to monitor the strain and temperature of the pipeline in the test section. Through the monitoring data, the trend of pipeline change and the potential hidden dangers were analyzed, which provided a direct basis for the operation and maintenance unit to predict and formulate the response plan in advance, and also could provide a reference for similar real-time monitoring projects of drainage pipeline.
