And 5, preliminarily detecting the fluidity and the strength of the slurry, and then determining the water inlet pressure and the feeding speed of the corresponding grouting material to ensure uniform properties of the slurry stirred in batches and pumped.
And 6, a precise membrane type pressure instrument is arranged at the discharge port, the grouting pressure is displayed in real time, and the pumping pressure of the screw pump is further fed back and adjusted through a pressure test result.
And 7, continuously stirring and grouting, wherein the start and stop of each component and the whole machine can be independently controlled by an electric control system or a remote controller in the midway, but the stop time cannot exceed the solidification time of the slurry under the state that the material exists in the machine.
And 8, if the estimated downtime exceeds the solidification time of the slurry or after the grouting is finished, closing the feeding vibration motor in time, and quickly cleaning the residual slurry in the equipment by pressurized water through the stirring cavity and the screw pump under the idling condition to avoid the residual slurry from being solidified in the equipment.
And 9, after the cleaning is finished, disconnecting the external water source and the power supply, and clearing the equipment to finish the cleaning.
