The invention relates to the technical field of pipeline detection, in particular to an urban sewage pipe leakage detection method. Urban sewage pipe leakage detection equipment comprises a water inlet pipe, a water meter and a water outlet pipe, and further comprises a detection mechanism, an adjusting mechanism, a measuring plate, an inflating mechanism, a sealing mechanism and an indicating mechanism; according to the urban sewage pipe leakage detection equipment, the detection mechanism is arranged between the water meter and the water outlet pipe, and when an indoor water pipe needs to bedetected, valves can be closed, and a rotating plate is rotated, so that a box body is positioned at the topmost end of a threaded groove; and air is blown into a barrel through an inflator, if the water leakage occurs, the water level is reduced, and if the water leakage does not occur, the water level is normal, so that a user can conveniently and rapidly overhaul the indoor water pipe, the cost is low, the detection effect is good, and the operation is simple and convenient; and the box body can be rotated to the bottommost end of the threaded groove, the sealing mechanism is moved to sealthe water meter, and an operator can observe whether the indicating wheel of the water meter rotates or not; and the position of the box body can be accurately judged by the operator according to a second scale bar.
