Water feed and drainage pipe as well as leakage detection system and detection method thereof

Abstract

The invention discloses a water feed and drainage pipe as well as a leakage detection system and a detection method thereof. A leakage detection device is provided with a detection circuit; the water feed and drainage pipe comprises an inner insulation layer and a test layer arranged on the outer side of the inner insulation layer; the test layer comprises a first conductive layer and a second conductive layer; an insulation barrier layer is arranged between the first conductive layer and the second conductive layer; the positive electrode and the negative electrode of the leakage detection device are respectively connected with the first conductive layer and the second conductive layer; when the water feed and drainage pipe is broken, conductive media inside and outside the water feed and drainage pipe communicate the first conductive layer with the second conductive layer, to form a loop for the detection circuit in the leakage detection device. In case of leakage of the water feed and drainage pipe, the leakage detection system can detect occurrence and an occurrence position of a leakage event in time, accurately and conveniently; furthermore, the leakage detection system is convenient to operate and high in enforceability.

Description

technical field [0001] The invention relates to the technical field of leakage detection of water supply and drainage pipes, in particular to a water supply and drainage pipe and its leakage detection system and detection method. Background technique [0002] The construction of urban water supply and drainage pipe network is an important part of urban planning and construction. For urban construction, leakage of water supply and drainage pipe network due to various natural reasons (aging, corrosion, etc.) and artificial construction is an inevitable problem. At present, it is difficult to monitor and locate the leakage of water supply and drainage pipelines. The main reason is that the water supply and drainage pipe network is widely distributed and the situation is complicated. Secondly, the water supply and drainage pipe network is deeply buried underground, so it is difficult to find leaks in time and implement countermeasures. [0003] The current municipal water supp...
