The invention discloses a pneumatic ultrahigh-pressure intelligent grouting
system. The
system comprises a central
control unit, a
slurry preparation unit, a grouting unit and a detection unit. The
slurry preparation unit comprises an integrated
slurry preparation
barrel, a thick slurry storage
barrel, a pneumatic thick slurry valve and a pneumatic
clean water valve arranged on a water inlet pipeline of the integrated slurry preparation
barrel; the grouting unit comprises a pneumatic grouting pump, a high-pressure valve, a slurry
inlet flow meter, a slurry return flow meter, a grouting pipeline for connecting a slurry outlet of the integrated slurry preparation barrel and a grouting hole of a working face, and a slurry return pipeline for connecting a slurry return opening of the integrated slurry preparation barrel and the grouting hole of the working face; the detection unit comprises a
pressure sensor, a lifting
detector, a density sensor and a temperature sensor arranged in the integrated slurry preparation barrel; and the central
control unit is in circuit connection with the detection unit, the pneumatic thick slurry valve, the pneumatic
clean water valve, the pneumatic grouting pump, the high-pressure valve, the slurry
inlet flow meter and the slurry return flow meter. Through the design, accurate control over slurry preparation and grouting is facilitated, the phenomenon of
pipe explosion of a grouting pipeline is avoided, the safety of
electric shock prevention of operators is improved, power
energy consumption is reduced, and meanwhile the intelligent level of slurry preparation and grouting of the grouting
system is also improved.
