Inflating and commissioning is a very important part of the air inflated membrane building construction process, and many people are curious about this inflation process.
Before the air inflated membrane is inflated, first of all, we should choose a better weather, when the wind reaches grade 4, it is not suitable for inflating construction. Then you have to check the connection between the membrane units, between the foundation and the membrane body, and between the steel cables, and check the installation of the supporting equipment of the air membrane building to make sure that the equipment can work normally. Finally, it is necessary to check the surrounding environment of the construction site, because the inflation process will produce a certain amount of swaying and shaking, and the membrane body should not be scratched during the inflation process.
How is the air membrane structure inflated?
The inflation and commissioning process is roughly divided into the following four steps:
First, start inflating
After all the preliminary preparations are in place, it is necessary to open all the fans to inflate the air membrane. Membrane body in the process of rising, there should be enough staff to ensure that all parts of the membrane body will not touch the fence, door frame, mechanical and electrical equipment. If the air membrane inflatable rise in the process of encountering obstacles, they need to pause inflatable, until after the removal of obstacles to continue to inflate.
Second, intermediate detection
When the inflation pressure reaches 60-100 Pa, the main body of the air membrane structure is basically formed. At this time, it is necessary to carefully inspect the membrane body, cable, door frame, electromechanical equipment and connections again, and deal with abnormal situations in time. If the air leakage gap is found in the connection, it needs to be temporarily blocked in time.
Third, inflate again
After solving all the problems appeared in the inspection, we can continue to inflate, and keep inflating to the designed pressure value.
Final Inspection
After the inflation is completed, the air membrane structure should keep the maximum design pressure for at least one hour before switching to the automatic control state. During this period, it is necessary to check and test each part of the air membrane structure.
Generally speaking, the inflation process of air membrane should not be more than four hours, and the staff of Xinyuan Air Dome usually chooses to carry out inflation and debugging in the morning to ensure that there is enough time to cope with all kinds of emergencies in the construction.
