Why would the plugging concrete pump pipe
When it is found that a bucket of concrete slump is very small, can not pump, should be in time the concrete from the bottom of the hopper release, if seeking trouble, forced pumping, easy to cause blockage. Avoid stirring with water in the hopper
When pumping, the operator shall observe the leftover material in the hopper at any time. The remaining material shall not be lower than the stirring shaft. If there is too little material, the air will be easily inhaled, which will lead to pipe blockage. The material in the hopper can not be piled too much, should be lower than the guard bar, so as to clean up the coarse aggregate and super large aggregate in time
When pumping, the choice of speed is critical, operators can not blindly map fast, sometimes more haste, less speed. When pumping for the first time, due to the large resistance of the pipeline, the pump should be pumped at low speed. After the pump is normal, the pump speed can be increased properly
Pump operator in pumping construction should concentrate, always pay attention to pumping pressure meter readings, once found that the pressure gauge reading suddenly increased, should immediately anti pump 2-3 stroke, and then pump, pipe can be excluded
