Support bosses 6 are arranged at the four corners of the bottom end of the base 1. The seat base is supported by the support boss 6 to facilitate the subsequent lifting and movement of the device. A control module is also provided.

[0028] The front end of each of the protective covers 8 is vertically fixed with a fixed plate 9 corresponding to the position of the plunger pump 3. Each of the fixed plates 9 is provided with a vertical slot 10, and each of the vertical slots 10 is slidably provided with a position sensor 11 for detecting the stroke limit position of the plunger pump 3. The position sensor 11 feeds back a signal to the control module. The stroke limit position of the plunger pump 3 is detected in real time by the position sensor 11 that can adjust the position on the vertical slot 10, so as to subsequently change the power size of the grouting to achieve variable grouting speed. The inlet of the plunger pump 3 is connected with a grouting pipe 12, and the outlet of the plunger pump 3 is connected with a grouting pipe 13. The slurry is sucked into the plunger pump 3 through the grouting pipe 12, and the slurry entering the plunger pump 3 is discharged from the grouting pipe 13, so that the transfer of the slurry completes the grouting. A three-way pipe connected to the outlets of the two grouting pipes 13 is also provided, and two outlets of the three-way pipe are provided, and each outlet is provided with a valve.

A spare lubricating oil pipe 53 is also provided on the plunger pump 3.

[0031] The method of using the grouting device with a double-cylinder grouting pump of the utility model is as follows: first, when the device needs to be moved, the rope can be passed through the position between the supporting boss 6 and the base 1 to lift and move the device for transportation. When the device moves to a suitable position to work, the control module controls the motor 42 and the cooling fan 43 to work. At this time, the motor 42 allows the oil to enter the high-pressure oil pipe 45 through the oil pump, thereby controlling the plunger pump 3 to work through the overflow valve 44. The plunger pump 3 draws the slurry into the plunger pump 3 through the slurry suction pipe 12, and discharges the slurry entering the plunger pump 3 from the grouting pipe 13, so that the transfer of the slurry completes the grouting. In this process, two plunger pumps 3 can be used individually or simultaneously to achieve individual or cyclic grouting operations, and different slurries can be sucked for grouting operations.

[0032] During the grouting process, the stroke limit position of the plunger pump 3 can be detected in real time by the position sensor 11, and fed back to the control module, so as to control the power of the motor 42 through the control module. In order to change the power of grouting later, to adjust the grouting speed, and to change the grouting speed and grouting amount according to the actual situation on site, so as to avoid the adverse consequences of too fast or too slow grouting speed, which may cause some surface uplift or affect the continuity of process implementation.
