Ningwu County rubber inflatable airbags have complete specifications, are wear-resistant and aging-resistant

Prepare for hours before water blocking operations, understand the flow conditions of the working pipe section, the source of upstream water flow and the distribution of the pipe network, the sources and water flow conditions of each branch pipeline, and the size of the operating opening, coordinate and discuss with the pipeline dispatching department, and schedule water outages and blockages. Water, water transfer plan. Including water diversion plan, water pressure control of relevant pump stations, and branch pipe blocking methods. The second test was carried out in a diameter pipe section, using an inflated air bag with a diversion hole. The staff wear protective masks and safety equipment, and are monitored by dedicated personnel on the ground. Measure the diameter of the pipe into which the rubber inflatable airbag enters the rainwater pipe to ensure that the size is within the range of use of the inflatable airbag. Before inserting the inflatable airbag, clean the outside of the inflatable airbag and the inflatable airbag. Inside the pipe, pull one end of the inflatable air bag (the end with the air nozzle) with a traction rope, and slowly put the inflated air bag into the pipe. Pay attention to the mouth of the pipe during the insertion process to avoid damaging the inflated air bag.
Before inflating the rainwater pipe rubber airbag
, it should be fully inserted into the pipe, inserted into the trachea, connected to the air pressure gauge and air pump, start the air pump, start inflating, and slowly open the air valve of the pressure control gauge. , the inflation pressure is controlled within the safe area outside the red area of the pressure mark. Observe the inflation status of the inflated air bag and evacuate the staff after confirming that the inflation status has started. Make sure no one is near the pipe during the inflation period. Tighten the traction rope and tie the rope firmly to the sleepers. Use the pressure control meter to observe the air pressure data of the inflated air bag. When the air pressure of the inflated air bag reaches the technical specification, close the air pressure control valve and inflate. Finish.
After the inflation is completed, the pressure control gauge remains connected to the trachea for a few minutes, and the data changes of the pressure of the inflated air bag are observed. If everything is normal, the pipeline construction work can be started.
During pipeline blocking and other operations, assign dedicated personnel to monitor and check the air pressure of the rubber inflatable airbags in rainwater pipes, maintain good and stable communication with the personnel at the work site, and report any abnormality in a timely manner to ensure the safety of the workers. At this point, the normal water blocking operation test has been completed and the destructive operation test has entered. Before the experiment, check again whether there are any people near the working section. Since the valve of the pipe section in this test was closed well, there was only a small amount of residual water. In order to simulate the uninterrupted water flow situation that will occur in future construction, we opened the valve in the incoming water direction a little. Water begins to enter the pipe. After a few minutes, the inflated airbag appeared to slide, and the water valve was immediately closed, ending the destructive test. Before removing the inflatable air bag, make sure there are no other people in the pipe
