When the intelligent sleeve grouting device with the assembled structure is used, slurry is injected into the material box from the outlet of the hopper, is discharged from the grouting pipe through the screw pump and is injected into the sleeve with the assembled structure. In the grouting process, the flow meter and the pressure sensor can acquire the flow and the pressure of the slurry in real time.

Example 3:
referring to fig. 1, 2 and 4, the embodiment of the invention provides another construction method of an intelligent sleeve grouting device with a fabricated structure, which comprises the following steps:
s1, butting the grout outlet of the grout pipe 4 with the grout outlet of the sleeve a, and butting the third port of the tee joint 14 with the grout outlet of the sleeve a; opening the first valve 8 and the second valve 9; closing the third valve 10, the pumping device 12;
