Complex Air-injection system & method are developed by Union Corp., which performs consistent shotcrete-spreading reducing the flow pulsation and dust by controlling pressure by two injection rings and Y-tube. This system is renovated from existing liquid-type supplying equipment, and this powder-type supplying system is solely manufactured and serviced by Union corp.



How it works
시스템의 원리
  • ① Preliminary Concrete grinding

    RMC is sent by the squeeze pump by high-pressure compressed air and grinded passing through the backward injection ring (spiral hole structure) and the flow pulsation caused by disruptions from piston movements of the squeeze pump is significantly reduced in this stage.

  • ② Mixing Set Accelerator

    as above, the backward injection ring transforms the grinded RMC into high-pressure cyclone and the grinded RMC is mixed with set accelerator through Y-tube. Then a mixture of RMC and set accelerator is obtained.

  • ③ Secondary mixing and discharge

    the shotcrete mixture goes through the forward injection ring (spiral hole structure) and the secondary mixing takes place. The off-set pulsation from the preliminary process is further corrected by secondary high-pressure compressed air, and the pulsation almost disappears and it discharges shotcrete.
