Abstract

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.

Description

technical field [0001] The invention relates to the field of water leakage detection and construction, and more specifically, the invention relates to a leakage location system for urban underground drainage pipes and a construction method thereof. Background technique [0002] Urban underground drainage pipes are intricate. With the frequent drainage and aging of drainage pipes, the leakage of drainage pipes often occurs. Whether it is the waste of precious water resources or the various economic losses caused by the leakage of drainage pipes, the leakage of drainage pipes must be paid enough attention to. Since the drainage pipe is installed under the wall or the floor, the leakage of the drainage pipe is not easy to be found, and it is not easy to check the leakage point after the leakage occurs. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned technologies, the present invention provides an urban underground drainage pipeline leakag...
