ABSTRACT

Water pipelines are generally buried in the ground, as a typical underground hidden engineering, their structural damages such as pipe burst, leakage, seepage and uneven settlement are characterized by strong concealment and long disaster-causing chain, which not only cause a large amount of waste of water resources, but also lead to safety accidents such as pavement collapse, which seriously threaten public safety. This study aims to propose a multi-dimensional monitoring system that integrates distributed fiber optic sensing and IoT technologies. Through in-depth analysis of the formation principle of pipe burst, leakage, seepage, uneven settlement and other problems, we utilize the deployment of Φ-OTDR fiber optic arrays (spatial resolution of 0.5m) to integrate high-precision pressure transmitters (accuracy ±0.1%FS) and electromagnetic flow meters (accuracy ±0.5%) to construct a multi-physical field synchronous sensing network, and to achieve the monitoring of pipeline pressure transient (sampling rate ≥100Hz), flow rate (sampling rate ≥100Hz), flow rate abnormality (detection sensitivity ≤0.1L/s), temperature gradient (resolution 0.1℃), negative pressure wave, stress and strain distribution (με level) holographic monitoring, and early warning and precise positioning. Engineering validation shows that this system helps to detect pipeline problems in time, reduce accident losses, guarantee the reliable operation of water pipelines, provide strong support for the stability and safety of the water transmission system, and provide key technical support for the construction of a resilient urban water transmission system.
