Real-Time Identification and Positioning of Sewer Blockage Based on Liquid Level Analysis in Rural Area

Sewer blockages delay sewage discharge or cause it to overflow, which pollutes the environment and is a public health hazard. This necessitates quick accurate identification positioning of sewer blockages. Following blockage, intercepted liquid level at upstream downstream blocking point changes. study established method for identifying by analyzing range rate change point. Through pilot-scale full-scale experiments, this summarized threshold values fluctuation drainage pipeline in normal operation, as well Moreover, blockage matrix was completed. rural areas can be identified positioned using mathematical tools such data-driven model. research allows real-time monitoring timely warning status, thereby reducing labor material consumption unnecessary earthwork excavation ensure stable operation pipeline.
