1. , a kind of residual concrete processing method of concrete pump, in piston concrete pump, it is characterized in that:

  • after the concrete force feed finishes, when discharge remains in residual concrete in hopper and the concrete delivery pipe, allow concrete pump dally earlier, the air pressure that produce this moment is discharged the above-mentioned part residual concrete that remains in hopper and the concrete delivery pipe from the front end of concrete delivery pipe, then foam body is sent into the concrete delivery pipe in the concrete pump housing from hopper, water filling in hopper again, make the concrete pump running, hydraulic pressure or the hydraulic pressure that produced this moment add air pressure pushing tow foam body, and residual concrete is discharged from the concrete delivery pipe front end.
