The invention discloses an urban
subsurface drainage pipeline leakage locating
system and a construction method thereof. The urban
subsurface drainage pipeline leakage locating
system comprises a drainage pipeline, a concrete layer wrapping the outer side of the drainage pipeline, waterproof
humidity detection devices, a wire pipeline and a locating and pre-warning device. The concrete layer is provided with a plurality of U-type groove-shaped waterproof
layers in an embedded manner, and the open ends of the waterproof
layers are in sealing connection with the drainage pipeline. The waterproof
humidity detection devices are arranged in the waterproof
layers in an embedded manner and used for reading
humidity data, and the waterproof humidity detection devices comprise controllers, humidity sensors and
wireless receiving and transmitting modules. The controllers are used for encoding the humidity sensors. A wire is arranged in the wire pipeline, one end of the wire sequentially penetrates the wire pipeline, the concrete layer and the waterproof layers to be electrically connected with the waterproof humidity detection devices, and the other end of the wire is connected with a solar
silicon cell panel. The locating and pre-warning device is used for locating and pre-warning during leakage of the drainage pipeline. The controller is used for comparing codes and humidity data of the humidity sensors with pre-stored humidity data and sending comparison information and the codes to the locating and pre-warning device through the
wireless receiving and transmitting modules. The urban
subsurface drainage pipeline leakage locating
system has the
advantage of achieving real-time pre-warning and locating during leakage of the drainage pipeline.
