Underground fire pipe leakage is a problem that should not be ignored; it not only affects the normal operation of the fire protection system, but may also pose a threat to the structural safety of the building. Therefore, it is crucial to detect and repair underground fire pipe leaks in a timely manner. This article will introduce the common underground fire pipe leakage repair methods.
First, locate the leakage point
First, the specific location of the leak needs to be determined. This can be done by using professional pqwt water leak detector equipment. In the survey area, along the pipeline line, every 0.5 to 1 meter distance for listening detection, and in the water consumption is relatively stable and the surrounding environment is quieter time period. This can more accurately determine the leakage of pipes buried under the road surface and mark the possible leakage location on the ground.
Second, close the water supply valve
After finding the leak, you need to close the corresponding water supply valves to cut off the water source to avoid continued leakage.
Third, empty the water pipe
Open the nearby water release valve to empty the water in the pipeline in order to carry out maintenance operations.
Fourth, clean the leak
Use a brush or cleaning tool to clean up the dirt and debris around the leakage point to ensure that the leakage point is clean and tidy.
V. Repair the leakage point
According to the specific conditions of the leakage point to choose the appropriate repair method. Common repair methods include: using epoxy resin, glue, sealant, etc. to seal; using waterproof tape, rubber gaskets and other materials to fix and seal the leak. If the pipe is severely damaged, it may be necessary to replace the entire section of pipe.
VI. Conducting Tests
After the repair is completed, open the water supply valve and test the repair effect. Make sure that the leak has been repaired and that there is no leakage. If there is still a leak, you need to re-repair and test again, until completely repaired.
In short, the repair of underground fire pipe leakage requires rigorous operational procedures and professional skills. Timely detection and repair of water leakage problems can ensure the normal operation of the fire protection system and safeguard the structural safety of the building. Therefore, it is recommended that fire protection systems be inspected and maintained regularly to avoid problems.
