[0023] It needs to be explained that since the mud slurry is in a stirring state, the mud slurry is difficult to realize mechanical pressurization, and the traditional pneumatic pressurization is easy to cause a large number of air bubbles in the mud slurry, which affects the structural strength of the mud slurry after forming, and the embodiment can make the grouting pressure disc 12 and the grouting pressure ring 14 fully contact the mud slurry and apply a pushing force to the mud slurry, so that the mud slurry is quickly discharged through the grouting pipe 3 under pressure, avoids blockage during grouting, and can ensure that the mud slurry is in a stirring state during pressure flow, further avoids the phenomenon of mud slurry agglomeration, and avoids the problem that pneumatic pressurization causes a large number of air bubbles in the mud slurry by mechanical pressurization, and ensures the structural strength of the mud slurry after grouting and solidification.

[0024] Specifically, in the embodiment, the scheme mainly includes the separation cylinder 7, the grouting pressure disc 12 and the grouting pressure ring 14, when pressurizing the grouting process, the mud slurry is injected into the separation cylinder 7 through the feeding hole 16, and enters the grouting storage barrel 2 under the guidance of the through hole 8, the control motor 4 drives the stirring shaft 5 and the stirring paddle 6 to rotate through the output end on one side, the stirring paddle 6 stirs the mud slurry, and the mud slurry is in a flowing state, avoiding the phenomenon of mud slurry agglomeration, at this time, the control electric push rod one 11 drives the grouting pressure disc 12 to move downward through the output end on one side, the grouting pressure disc 12 enters the separation cylinder 7 after passing through the feeding hole 16, the control vacuum pump 15 exhausts the air in the grouting storage barrel 2 as much as possible, after the air exhaust is completed, the control electric push rod two 13 drives the grouting pressure ring 14 to move downward through the output end on one side, the grouting pressure disc 12 and the grouting pressure ring 14 move downward synchronously, when the grouting pressure disc 12 and the grouting pressure ring 14 contact the mud slurry and apply pressure, the mud slurry is discharged through the grouting pipe 3 under mechanical pressure, the maximum downward movement distance of the grouting pressure disc 12 is the height when the grouting pressure disc 12 does not contact the stirring paddle 6, when the grouting pressure disc 12 is in a fixed position, the grouting pressure ring 14 can continue to move downward, and the grouting pressure ring 14 extrudes the mud slurry between the grouting storage barrel 2 and the separation cylinder 7, since the stirring paddle 6 rotates without limitation, the mud slurry is always in a stirring state and is extruded, and a small part of the mud slurry remaining on the outside of the stirring paddle 6 flows out of the grouting pipe 3 in a natural state.
