Concrete pump truck pipe blocking we often encounter such things happen, is also a very headache, the impact of construction efficiency is also a waste of a lot of manpower and material resources, the use of ordinary methods to solve the past for a long time, too delayed. So here's a good idea!
1, when the concrete pump car pipe blocking, we should immediately stop pumping, do not let the concrete blocking more real, we found that the pipe is blocked by the reverse pump to the concrete in the pipe suction back or loose, and then take the positive pump transmission, the blocked position impact open.
2, when the method of positive and negative pump impact is not good, we need to stop the concrete pump truck, the boom all straightening with a wrench or iron rod knock on the conveying pipe, blocked position and not blocked the sound is different, so to judge the blocking position, and then take apart this section of the conveying pipe to dispose of the blocked concrete, which can also save a lot of time.
