Underground pipeline leakage detection method for buried water pipes

The tap water transported by underground pipelines will soon experience leakage problems, and it will be found that there may not be any signs on the surface when the leakage occurs. Even if water seeps out from the surface, the leakage point may not be the same as the leakage point, especially when there is a cement or other covering layer on the ground. Underground pipeline leakage detection companies summarize that the most commonly used methods for pipeline leakage point detection are: listening method, acoustic vibration method, which is commonly known as pipeline leakage detector/leak detector

Different methods have their own advantages and disadvantages. The following are several pipeline leak detection methods for your reference:

1. Regional metering method: Guangxi Zhongshui refers to the statistical comparison between the flow meters entering and leaving a certain area of the water supply network. The difference must be the unmeasured loss of this interval. If there are no other unmeasured consumptions, then the leakage loss of this interval can be known, which will give the manager a clear idea. The denser the partition area and the clearer the segmentation, the clearer the understanding of the water leakage situation in each section. But the watch cannot be too densely packed. This method cannot determine the exact location of the water leakage point, so it cannot be used as a basis for specific repair or breaking of the road surface. Key point: Leakage causes measurement errors.

2. Listening method and sound vibration method: Listening method refers to using a certain sound transmission tool to listen for the sound of water leakage, and determining the location of water leakage based on the size and sound quality characteristics of the water leakage sound. From simple mechanical listening rods to various listening leak detectors, this method essentially refers to sound vibration method. At present, it is developing rapidly and is a widely used and effective method both domestically and internationally. It is also the method that this manual will focus on introducing. The relevant leak detectors should also belong to the acoustic vibration method system.
