Abstract
Disclosed are a shallow-buried leakage-proof pipeline and a method for operating the same. The leakage-proof pipeline includes a programmable logic controller (PLC), an outer pipe, an inner pipe, a first water-pressure sensor, a second water-pressure sensor, an electromagnetic valve, and a movable water leakage detection device. The PLC is arranged on the ground. The outer pipe and the inner pipe are both shallowly buried along a horizontal direction, and the inner pipe is coaxially arranged in the outer pipe. The first water-pressure sensor and the electromagnetic valve are both arranged at a water inlet of the inner pipe, and the second water-pressure sensor is arranged at a water outlet of the inner pipe. The movable water leakage detection device is arranged at a bottom of the outer pipe.
