Concrete pumping is usually affected by many factors, such as site conditions, operators' non-compliance with operating regulations, etc. However, pipe blockage is likely to occur during the concrete pumping process. If it is not handled quickly and effectively, it will not only delay the overall construction Progress and cannot ensure the quality of construction. So we write this article for your reference. 1. Operation error may cause pipe blockage First, operators are distracted in actual operations. Second, the choice of pumping speed lacks rationality. In the pumping process, the speed (that is, the pumping displacement) must be selected reasonably, and the operator cannot just pay attention to the speed. Sometimes the speed is not a good thing. When pumping for the first time, because the pipeline resistance is quite large, in this case, it is necessary to pump at a low speed. After ensuring that the pumping is normal, the pumping speed can be adjusted appropriately....
