Due to long-term exposure, outdoor pipelines are affected by various natural and man-made factors, and are prone to aging, corrosion and other problems, which can lead to water leakage. Water leakage not only causes waste of water resources, but also may cause ground settlement, building structure damage and other safety issues. Therefore, regular pipeline leakage detection is very necessary.
Analysis of water leakage causes
-Natural factors: such as soil movement, tree root intrusion, etc.
-Material aging: with the passage of time, pipe materials will gradually age.
-Construction quality: damage caused by improper construction.
-External impacts: e.g. excavation operations, crushing by heavy vehicles, etc.
Common detection methods
1. Acoustic leakage detection
-Use water leakage detector to capture the sound of water leakage and locate the leakage point.
-Applicable to pipes of different materials.
2.Ground radar detection
-Detects the location and structure of underground objects through electromagnetic wave reflection.
-Can detect deeper buried pipes and potential problems.
3. Gas Tracer Method
-Injects a specific gas into the pipeline and searches for the location of the gas leak through a detector.
-Especially effective for small cracks.
4. Infrared Camera Detection
-Uses infrared technology to identify temperature differences and locate areas of leakage.
-Particularly suitable for night operation and more effective.
Implementation steps
1. Site survey: Understand the layout, material and surrounding environment of the pipeline.
2. Selection of method: Select the appropriate detection means according to the actual situation.
3. Implementation of the test: leakage detection according to the selected method.
4. Data analysis: organize the collected data to determine the location of the leakage.
5. Repair program: develop a specific repair plan.
Maintenance Recommendations
-Regular inspection: It is recommended to conduct a comprehensive inspection at least once a year.
-Professional maintenance: Hire a professional team to carry out inspection and repair work.
-Updating and reconstruction: For old pipes consider replacing them with new material pipes.
-Daily monitoring: Install intelligent monitoring system to monitor the pipeline status in real time.
Conclusion
Outdoor pipeline leakage detection is a complex but crucial task. By adopting advanced technology and scientific methods, it can effectively reduce the waste of water resources and ensure the safe and stable operation of public facilities.
