Description

Technical Field

[0001] This utility model relates to the field of drainage pipe leakage detection technology, specifically a drainage pipe leakage detection device. Background Technology

[0002] As a core facility in building and municipal engineering, drainage pipes are mostly made of materials such as cast iron, PVC, and HDPE and are responsible for the discharge of rainwater and sewage. However, drainage pipes often leak due to disrepair over the years. Pipe leaks are mainly caused by aging and corrosion, foundation settlement, mechanical external force or failure of connection seals, water seepage erosion of building structures, pollution of soil and groundwater, and the growth of bacteria and the emission of odors, which threaten public health and safety and the durability of facilities.

[0003] Existing detection methods (such as visual inspection and segmented water pressure testing) require partial shutdown of the system and disassembly of the pipeline. Leakage points are identified by manual entry or equipment endoscopy. The operation process is highly destructive, time-consuming, and cannot cover hidden parts (such as buried pipe sections). At the same time, static detection is difficult to simulate dynamic drainage conditions and cannot accurately locate micro-leakage or crack propagation risks, leaving room for improvement.
