Summary: | The invention discloses a water leakage detection method for a drainage pipeline. The water leakage detection method comprises the following steps that S1, a power supply positive electrode and a power supply negative electrode are placed in the drainage pipeline; S2, a plurality of cables are arranged right above the drainage pipeline at intervals in the direction parallel to the drainage pipeline, and a plurality of measuring electrodes are further arranged on each cable at intervals; S3, direct current is supplied to the drainage pipeline through the power supply positive electrode and the power supply negative electrode; S4, potential difference data of each measuring electrode is measured; and S5, a two-dimensional potential difference contour map is drawn according to the potential difference data and the position coordinates of the measuring electrodes, and the position of a water leakage point of the drainage pipeline is determined according to the map characteristics of the two-dimensional potential |
