[0023] A PLC controller 7 is installed at the top of the grouting device housing 1. The PLC controller 7 is electrically connected to the first drive motor 3. A mounting support plate 8 is installed on one side of the grouting device housing 1. A positioning groove 9 is opened on the side of the mounting support plate 8 away from the grouting device housing 1. A second drive motor 10 is installed on the side of the mounting support plate 8. The second drive motor 10 is electrically connected to the PLC controller 7. An adjusting threaded rod 11 is installed on the output shaft end of the second drive motor 10. The adjusting threaded rod 11 is located inside the positioning groove 9. The inside of the positioning groove 9 is away from the grouting device housing 3. A movable connecting block 12 is installed on the inner wall of one side of the second drive motor 10. An adjusting threaded rod 11 is rotatably connected to one side of the movable connecting block 12 on the side away from the second drive motor 10. A movable sliding screw block 13 is threadedly connected to the outer end of the adjusting threaded rod 11. An electric push rod 14 is installed on the side of the movable sliding screw block 13 away from the grouting device housing 1. The electric push rod 14 is electrically connected to the PLC controller 7. A movable push rod 15 is installed at the output end of the electric push rod 14. A grouting pump 16 is installed on the side of the grouting device housing 1 located on the mounting support plate 8. The grout pump 16 is electrically connected to the PLC controller 7. A grout extraction pipe 17 is installed on one side of the grout pump 16, extending into the interior of the grouting device housing 1. A conveying grouting telescopic pipe 18 is installed on the side of the grout pump 16 away from the grouting device housing 1. A grout discharge pipe 19 is installed on the side of the conveying grouting telescopic pipe 18 away from the grout pump 16. The side of the grout discharge pipe 19 closest to the grouting device housing 1 is fixedly connected to one side of the movable push rod 15. A flow sensor 20 is installed in the middle of the grout extraction pipe 17, and the flow sensor 20 is electrically connected to the PLC controller 7. The bottom of the grouting device housing 1 is equipped with a load-bearing base plate 21. Support legs 22 are installed at the four corners of the bottom of the load-bearing base plate 21. Casters 23 are installed at the bottom of the support legs 22. A push handle 24 is installed on one side of the grouting device housing 1. The second drive motor 10 is started to drive the adjusting threaded rod 11 to rotate, which drives the moving sliding screw block 13 to move on the adjusting threaded rod 11, thereby realizing the horizontal position adjustment of the grouting discharge pipe 19. The electric push rod 14 is started to push the movable push rod 15, which in turn drives the grouting discharge pipe 19 to move back and forth.

[0024] Working Principle: When using this grouting device for foundation reinforcement and correction, firstly, use the push handle 24 and the casters 23 to move the grouting device to a suitable position. Connect the power supply to provide power to the equipment. Pour the grouting material into the grouting device housing 1 through the grouting inlet 2. The operator sets the mixing program on the PLC controller 7 and starts the first drive motor 3 to rotate the movable rotating rod 4. The mixing blades 6 at the outer end of the movable rotating rod 4 rotate accordingly, mixing the grouting material in the housing. After the mixing is complete, according to the specific location of the foundation that needs reinforcement or correction, start the second drive motor 7 via the PLC controller. The drive motor 10 drives the adjusting threaded rod 11 to rotate, which in turn moves the sliding screw block 13 on the adjusting threaded rod 11, thereby adjusting the horizontal position of the grouting discharge pipe 19 without moving the entire device and affecting the uniformity of grouting. If it is necessary to adjust the distance between the grouting discharge pipe 19 and the building foundation, the electric push rod 14 can be activated by the PLC controller 7 to push the movable push rod 15, which in turn moves the grouting discharge pipe 19 back and forth, precisely adjusting the position and distance of the grouting discharge pipe 19 so that it is aligned with the part that needs grouting. During grouting, the flow sensor 20 monitors the flow rate of the grout in the grouting pipe 17 in real time. The flow sensor 20 is a Cellix sensor. The Flow Sensors series monitors and feeds the data back to the PLC controller 7. The PLC controller 7 compares and analyzes the preset grouting volume parameters with the real-time flow data, and precisely adjusts the grouting volume by controlling the working state of the grouting pump 16. When everything is ready, the grouting pump 16 is started. The grouting pump 16 extracts the evenly mixed grouting material from the grouting device box 1 through the grouting pipe 17, and delivers it to the grouting discharge pipe 19 through the grouting extension pipe 18. Finally, the grout is injected into the weak parts of the building foundation or the area that needs to be corrected through the grouting discharge pipe 19 to complete the foundation reinforcement and correction work. The grouting pump 16 adopts the SYB hydraulic grouting pump model. After the grouting is completed, the first drive motor 3, the second drive motor 10, the electric push rod 14 and the grouting pump 16 are turned off. The grouting device is moved to a suitable position by using the push handle 24 and the universal caster 23 for the next grouting operation.
