> Bridge inflatable airbags From a technical point of view, the bridge inflatable airbags produced in the south are all cold-bonded. Later, in the process of continuous practice, the cold-bonded process was slowly replaced by the hot-pressed vulcanization one-time molding process. , but some southern manufacturers are still using this process, because the cost of bridge inflatable airbags produced by this process is relatively low, but the inflatable mandrel produced by the cold bonding process has a fatal flaw: when overheated, the bonding joint will open and cause the use of The service life is much lower than the bridge inflatable airbag produced by hot-pressing and vulcanizing in one step.
Bridge rubber airbags, bridge masters, using airbags is a kind of knowledge. It seems simple, but the operation is complicated. The first is the inflation pressure. Too much or too little inflation pressure will cause inaccurate concrete pouring dimensions. Excessive inflation pressure will cause a problem. On the one hand, it causes the air bag to deform, and the original square becomes round, and the mouth of the air bag is flushed out, or the air bag is exploded, etc.; on the other hand, the pressure is too small. If the pressure is too low, too much concrete is poured, causing holes. Small, the bridge load is heavier. Faced with this situation, how will we change the status quo? The first is to solve the inflation problem. For relatively long airbags, we must pay attention to the back pressure problem when inflating. The tee and pressure gauge connected to the airbag are only the measuring head of the airbag. The pressure at the head of the air bag does not represent the pressure at the tail of the air bag. When the head of the air bag shows that it has not reached the rated pressure, the pressure at the tail of the air bag may be too high. When inflating, when the air bag pressure is almost reached, stop inflating and wait for the air bag to After the internal pressure stabilizes, continue to inflate. During the inflation process, the speed must be slowed down to avoid overpressure
