1. repeated anti-pump and pumping, progressive absorption of concrete to the hopper, once the mixing pump;
2. the use of methods such as mallets, blocked parts identified, hit the concrete after the song, repeating against the pump and pump, excluding plug;
3. when the above two methods fail, after the concrete pressure, dismantle the blocked parts of the duct, discharged after concrete plug, before they can take over. Before pumping again, should first be ruled out after the air in order to tighten joints
