The tail of the grouting head 23 and the grouting frame 24 are elastically connected. Sensors, these sensors are respectively connected with the controller 4 through cables.

The grouting machine is driven by full hydraulic pressure. All the movements of the whole machine and the grouting work are intelligently controlled by the hydraulic system combined with the controller 4. The touch screen displays the working status of the grouting machine without manual intervention. The walking of the grouting machine is driven by a hydraulic motor, and the signal is transmitted to the controller 4 to control its start and stop through the touch screen.

Both the pressure grouting pump mechanism 22 and the grouting head 23 insertion and extraction actions are connected to the controller 4 by their respective position control loops and can be manually controlled by the operator through the touch screen. During automatic grouting work, the operator selects the number and position of the grouting heads 23 on the touch screen according to the requirements of the warehouse surface construction, and then presses the automatic grouting start key on the touch screen, and the automatic grouting program starts to work. The piston of the grouting pump corresponding to the selected grouting head 23 moves, and the piston of the grouting pump corresponding to the unselected grouting head 23 does not move. The action process is as follows: the controller 4 controls the hydraulic system so that the piston of the pressure grouting pump mechanism 22 reaches the initial position, and then the piston of the pressure grouting pump mechanism 22 retracts, and the liquid inlet valve is opened under the action of negative pressure, and the cement slurry is discharged from the stirring storage. The liquid barrel 21 is sucked into the grouting pump, and when the stroke of the piston reaches a predetermined value (at this time, the sucked grout reaches the required grouting amount set value), the sensor sends out an instruction, and the controller 4 instructs the reversing valve in the control circuit Action, the piston lifts out, the liquid outlet valve opens, the slurry is pressed into the grouting head 23, and sprayed out from the spray hole 30 of the grouting head 23. After the piston reaches the initial position, the sensor sends an instruction, the controller 4 instructs the reversing valve in the control circuit to act, the piston stops, and the air in the grouting head 23 is emptied.

When the depth of the slurry head inserted into the RCC reaches the set value), the sensor sends an instruction, the reversing valve in the 22-position control circuit of the pressure grouting pump mechanism automatically moves, the piston of the grouting pump retracts, and the liquid enters under the action of negative pressure The valve is opened, the slurry is sucked in, and when the piston stroke reaches the predetermined value, the piston of the grouting pump is pushed forward to start grouting. When the reciprocating action of the piston of the grouting pump reaches the amount of grouting, the piston stops, and the number of repetitions is controlled and measured by the controller 4. When the amount of grouting is reached, the grouting is completed. The controller 4 controls the automatic action of the reversing valve in the plug position control loop, and the piston of the plug cylinder 29 retracts, driving the grouting head 23 to be pulled up. When the grouting head 23 is pulled out to the original position, the control loop is then driven Automatically connect the oil path of the travel motor, the vehicle body 1 automatically starts to retreat, and when the next grouting position is reached, the travel motor stops, the vehicle body 1 stops positioning, and the whole mechanism repeats the above grouting process. The distance that the vehicle body 1 moves is controlled by the controller 4 .

After the whole grouting work is completed, the grouting machine stops automatically, and the grouting work can be interrupted by touching the grouting stop button. After the grouting is stopped, the agitator 27 is still stirring to prevent the cement slurry from settling, and the agitator 27 stops working after the grouting module 20 is cleaned. The grouting machine is provided with a liquid level alarm, and when the slurry in the stirring liquid storage tank 21 is insufficient, a signal is sent to remind the operator to replenish the slurry. During grouting work, the throttle of the engine is fixed, and the driver only needs to control the direction and monitor the touch screen in the cab to understand the action of grouting.

The metamorphic roller compacted concrete grouting machine is provided with four mutually independent grouting pumps, which are respectively driven by four hydraulic cylinders. The four grouting ports of the grouting pump are connected, and the grouting ports are independently supplied to four grouting heads 23 .
