The commodity concrete pump before the responsible person should understand the site project, which required concrete variety, technical requirements, construction scheme, water volume, time and site construction preparation have pouring conditions (the site, technical preparation, etc.) by on-site fill day notice entrusted commercial concrete production department to arrange the production. If orders not one day handed to the production department, in the second days before the opening of the content level, webmaster should verify the pouring time and pouring position, after the opening order must first with the car back to the commercial concrete production department.

2, concrete pumping before the responsible person should be mastered before operation is completed, the water circuit is guaranteed, and fill in the commercial concrete production department will notify the client station, by the concterte pump and safety supervisor to take over the site for piping installation and commissioning, to cast state.

3, start pumping, the use of appropriate water wetting pump hopper, pipes and other parts of contact with commercial concrete. No abnormal after the inspection line, according to the pipe distance using cement mortar, proper lubrication, lubrication pipeline with cement mortar, should according to the project, or abandoned, or dispersed casting, it is strictly prohibited to run for mortar concentration in the same place cloth.

4, responsible for the quality of the casting process and pump machine operator to deal with each car concrete visual quality control, concrete pouring concrete, if the goods are found through concrete slump, segregation and bleeding, serious false clots and other abnormal conditions shall notify the laboratory personnel immediately, the scene should be unable to handle the processing of commercial concrete mixing plant back from the station, laboratory test, when the situation is normal and then transferred to normal pumping.

5, the concrete pump should be continuous, when commodity concrete supply is insufficient or not working properly, can slow down the pumping speed, continuous pumping pumping, but shall not exceed the total time from mixing to allow the pouring duration (generally not more than 2 hours). Pumping difficulties, pump pressure rise, pipe vibration shall not be forced pumping, should immediately check the pipeline, take measures to remove obstacles, when the pipe is blocked, should be stopped, anti pump, drain, re take over. In the pumping process, the big grille and sundries on the hopper grille should be collected in time, and no water or additives are added to the hopper.

6, after the end of the concrete pouring, the pipeline will be removed by the receiver, and the concrete pump is responsible for cleaning the pipe and pump with water and mortar. The records shall be carefully recorded and the contents can be traced back in detail.
