How to handle it about concrete pump blocked pump?

In situ concrete construction in most afraid of is the emergence of concrete pumps pump blocking phenomenon, which not only affect the construction schedule, but also a waste of engineering materials. Now Hunan people and heavy engineering and technical personnel to tell you how to deal with concrete pump blocked pump!
Usually concrete delivery pumping system operation abruptly interrupted, and there is abnormal sound, concrete pump has a strong vibration, but without a corresponding vibration in the pipeline. This is likely to be clogged with a valve at the outlet. Remedy: Pour water into the hopper mud, repeated forward and reverse start the pump, so that blockage open mouth open. If you still can not rule out the blockage, it can only be artificially excluded, remove the tubing, remove debris at the discharge port with a valve.
In fact, the mechanical equipment and people, but also require routine maintenance and repair, or else no matter how good, and then stick the concrete pump problems will arise, so the completion of each construction should be promptly flushed with high pressure water pump and pipeline, Remove residual, including concrete, so that we can maximize the use of, for their own cost savings to bring more revenue!
