Multi-points synchronous measurement of pressure used in burst and leakage monitoring along the water transmission pipeline

When bursted, the flow can reach hundreds to thousands of cubic meters within a few minutes on large-scale pipelines whose water supply capacity is 5-10 m3/s. It could trigger secondary disasters in the densely populated areas. But the accident is hard to be monitored and be found, because the leakage flow is often only 1% to 5% of the water supply capacity. This paper presents the synchronous measurement for the burst and leakage monitoring along the pipelines. The research found that it can alarm timely in 3min ~ 5min and provide key information such as detonation location and the amount of the explosion leakage. The method has been applied to Xijiang River Diversion Project in China and the water supply capacity is 3.5 million m³/d(40.5m³/s).
