Abstract

The invention provides an urban water delivery pipeline having high leakage monitoring accuracy. The urban water delivery pipeline comprises a water delivery pipeline body, wherein the water delivery pipeline body is provided with a strip-shaped protrusion in the axial direction and is provided with an inner groove in the length direction, and the inner groove is packaged through a locking clamp in the length direction, so that a closed inner cavity with two opened ends is formed inside the strip-shaped protrusion. Distributed optical fibers penetrate into the inner cavity in the axial direction of thewater delivery pipeline body and are connected with the side wall of the inner cavity through multiple elastic devices evenly distributed in the inner cavity. The urban water delivery pipeline can amplify optical fiber monitoring vibration signals, the phenomenon that traditional embedded pipeline optical fibers are easily damaged and have the characteristics of being sensitive to outside vibration such as pedestrians, vehicles and rainwater is avoided by adopting a packaging process, leakage signals can be sensed rapidly, accordingly early warning of the pipeline is achieved, and the urban water delivery pipeline is suitable for the field of online monitoring of municipal water supply and drainage and petroleum or natural gas pipelines.

Description

technical field [0001] The invention belongs to the field of municipal water supply and drainage, in particular to an urban water delivery pipeline with high leakage monitoring accuracy. Background technique [0002] At present, distributed optical fiber has been widely used in leakage monitoring of oil pipelines and natural gas pipelines. Different from the existing environment of the above-mentioned pipelines, such as municipal water supply and drainage pipelines are mostly buried pipelines, and the sensitivity of optical fibers arranged on the outer wall of the pipeline is significantly affected by the external environment, such as pedestrians, vehicles, rain, strong winds, etc.; at the same time, external destructive events, Such as excavation, construction, landfill, etc. will cause the optical fiber to be artificially damaged when it is not put into use or during use. These restrictive factors not only make the obtained optical fiber signals relatively weak, but also ...
