The construction of pipeline blocking airbags requires meticulous operation. From the selection of airbags, precise positioning to pressure control, every link needs to be professionally managed.
Steps and precautions for the construction of pipeline sealing airbags
The construction of pipeline sealing airbags is a process that requires careful operation, and its detailed process is as follows:
1.The preparation stage of the pipeline blocking airbag
Firstly, it is necessary to carefully inspect the airbag accessories in the inflation device of the circular pipeline circuit breaker in municipal engineering to ensure that they are intact and there is no air leakage or tool leakage. Subsequently, use an air pump to inflate the airbag, but be careful not to exceed a pressure of 0.15MAP. Finally, carefully check the rubber airbag again to confirm that there is no air leakage.
2.Airbag placement
On the premise of ensuring that the pipeline inlet is opened as much as possible, slowly push the inflatable rubber airbag of the culvert to the predetermined position. Subsequently, by inflating the pipeline circuit breaker, the airbag is fully inflated at an appropriate pressure (usually set at 0.25MP). During this process, careful attention should be paid to the placement of the airbag, ensuring that it maintains a certain distance from the pipe joint to prevent the sealing effect from being affected or unexpected situations such as airbag rupture
3.Fixed pipeline blocking airbag
To ensure a tight fit between the rubber airbag and the rubber tube and avoid separation, we need to use wire to firmly fix the two together.
4.The inflation process of the pipeline blocking airbag
During the inflation process, the air volume should be slowly and steadily increased to prevent the rupture of the pipeline inflatable airbag due to rapid inflation. At the same time, be careful during operation to avoid dragging the airbag and protect its outer wall from damage.
5.Monitor the air pressure of the pipeline blocking airbag
During the construction process, it is necessary to continuously monitor the pressure changes of the concrete inflatable airbags. Once the pressure drop rate is found to be slow, the operation should be stopped immediately, and the air pump should be used for re inflation, carefully checking for any air leaks.
6.Additional explanation:
Cleaning of Inflatable Airbag Surface: After each use, the surface of the airbag should be thoroughly cleaned and carefully inspected for any remaining accessories or debris to ensure its cleanliness and readiness for next use.
Connection inspection between airbag and pipeline: After connecting the airbag accessories to the pipeline, it is necessary to conduct a gas pressure test to confirm whether the connection is secure and check for any air leakage.
Pipeline inspection: Before inserting the airbag into the pipeline for sealing, the inner wall of the pipeline should be carefully inspected for smoothness, absence of sharp objects or burrs, to ensure that the airbag can be safely and effectively sealed.
Inflation method: When inflating, the airbag should be slowly and evenly inflated to avoid over inflation causing airbag rupture or damage. Through these steps, we can ensure the long-term effective use of pipeline sealing airbags while ensuring the safety and quality of the construction process.
