Leaks in underground water pipes are a problem that we may encounter in our daily life, and how to effectively detect and repair these leaks becomes an important issue that we need to solve. In order to help you solve this problem better, this article will introduce some underground plumbing leak detection methods and repair tips, let's take a look!
What are the leak detection methods for underground water pipes?
Detection and repair is an important task when it comes to underground water pipe leaks. Here are a few common underground plumbing leak detection methods:
1. Listening Leak Detection Method: Using a listening pipe leak detector, place the pipe leak detector sensor on a valve or fire detector and listen to the sound of the leak. In general, the closer the leak, the louder the leak. Conversely, the smaller the sound of the leak, the farther away the leak is. By amplifying the pipeline leak detector point by point, the leak can be accurately located.
2. Tracer element leak detection method: add tracer elements, such as helium, nitrogen and other gases, inside the pipeline, and then use the leak detector to detect the presence of these elements externally. This method is mainly used to detect small leaks in pipelines.
3. Pressure test method: By adding pressure to the inside of the pipeline and observing the pressure change to determine whether there is a leak. This is a simple and effective method, but you need to pay attention to the pressure can not be too high, so as not to damage the pipeline.
4. Infrared leakage detection method: use infrared cameras to photograph the outside of the pipeline to observe whether there is a leakage of heat sources. This method requires certain technical equipment and experience.
5. Gas Detection Method: Use a gas detector to detect the gas composition around the pipeline, such as the presence of methane, ethane and other gases. This method is mainly used to detect leaks in underground gas pipes.
If an underground water pipe is found to be leaking, the appropriate leak detection method can be chosen to repair it according to the specific situation. The following are some common repair methods:
1. Local repair method: for some small-scale leaks, you can use quick joints, hoops and other local repair tools to repair.
2. Overall repair method: for some large or complex leaks, you need to use the overall repair method, such as in-situ curing method, grouting method.
3. Replacement of pipes: If the pipes are seriously damaged or cannot be repaired, you can consider replacing the whole pipes.
In conclusion, the detection and repair of underground water pipe leakage is a highly technical and empirical work, which requires professional technicians to operate. If you encounter the problem of underground water pipe leakage, it is recommended to contact professionals for detection and repair in time.
