[0024] The present invention has the following beneficial effects:

[0025] The present invention uses a grouting pump to draw the slurry in the storage tank into the interior of the connecting pipe. The slurry flows in the connecting pipe and enters the interior of the casting component through the switching pipe. After the grouting pipe is placed inside the stone component, the slurry enters the interior of the stone component through the grouting pipe. An anti-backflow component is provided inside the grouting pipe to prevent the slurry inside the stone component from flowing back into the grouting pipe after grouting is completed. The anti-backflow component pulls the separation component to deform when moving, and a gap is generated between the anti-backflow component and the inner wall of the grouting pipe through the squeezing of the separation component, so that the slurry can be injected into the interior of the stone component through the grouting pipe. An auxiliary component is provided at the end of the grouting pipe to prevent the slurry backflow from directly impacting the grouting pipe, thereby improving the service life of the grouting pipe.

[0026] The electric push rod of the present invention extends to the outer end away from the storage tank, and is synchronously extended by pulling the telescopic tube through the bracket. The driving machine drives the rotating column to rotate by engaging with the engaging ring, so that the grouting pipe extends to the outer end of the electric push rod. When the grouting pipe needs to be used, the electric rod pulls the limit ring to retract upward. After the pressure on the hose becomes smaller, the grouting pipe can pull the hose to slide on the bottom of the fixed plate, which is convenient for the use of the grouting pipe. The hose is squeezed by the limit ring and can be lowered according to the required length to avoid the hoses from being entangled with each other.

[0027] The gas generated by the air pump of the present invention enters the interior of the circular frame through the extension pipe, and the gas enters the interior of the gas collecting pipe through the circular frame. When the air pressure inside the circular frame is sufficient, the gas can push the push rod to extend toward the outer end of the gas collecting pipe. The push rod pulls the conical frame to move while extending. When the arc block moves, it is squeezed by the separation component and separated from the inner wall of the grouting pipe, so that the slurry can be grouted into the stone component through the grouting pipe. The arc block squeezes the elastic rod and the elastic sheet to contract. When the air pump stops working, the elastic rod and the elastic sheet push the arc block to contact the inner wall of the grouting pipe, seals the inner wall of the grouting pipe, and prevents the slurry from flowing back.

[0028] When the conical frame of the present invention moves, the positioning ball is pulled by the synchronization rod to slide on the surface of the positioning frame, and the arc spring plate moves synchronously with the movement of the positioning ball. When moving, the arc spring plate is squeezed downward by the squeezing frame, and the vertical plate squeezes the elastic plate downward through the deformation of the arc spring plate. The elastic plate squeezes the arc block into the inside of the conical frame through the connection with the arc block, so as to avoid affecting the grouting work. When the air pump stops working, the spring pulls the conical frame to reset through the positioning ball. When the arc spring plate is reset by elasticity, the elastic plate is squeezed to push the arc block to extend out of the outer end of the conical frame, so that the arc block can quickly contact the inner wall of the grouting pipe, thereby improving the efficiency of preventing backflow.

[0029] The movable tube of the present invention is moved out of the outer end of the grouting tube by the push rod so that the slurry can be injected into the interior of the stone component through the movable tube. The slurry will impact the blocking plate when it flows back. After the blocking plate is impacted, the push rod is pushed by the movable tube to quickly reset, so that the arc block can quickly contact the inner wall of the grouting tube, thereby improving work efficiency.

[0030] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The vertical plate 55 squeezes the elastic plate 50 downward through the deformation of the arc spring plate 52. The elastic plate 50 squeezes the arc block 45 toward the inside of the cone frame 43 through the connection with the arc block 45. , to avoid affecting the grouting work, when the air pump stops working, the spring 53 pulls the conical frame 43 to reset through the positioning ball 51. When the arc spring plate 52 is reset by elasticity, the elastic plate 50 is squeezed to push the arc block 45 to extend out of the outer end of the conical frame 43, so that the arc block 45 can quickly contact the inner wall of the grouting pipe 16, thereby improving the efficiency of preventing backflow. The mobile tube 62 moves out of the outer end of the grouting pipe 16 through the push rod 42, so that the slurry can be injected into the interior of the stone component through the mobile tube 62. When the slurry refluxes, it will impact the blocking plate 64. After the blocking plate 64 is impacted, it pushes the push rod 42 through the mobile tube 62 to quickly reset, so that the arc block 45 can quickly contact the inner wall of the grouting pipe 16.
