After the demoulding of the secondary lining trolley is completed, the arc truss 1 is moved between the steel mold 3 of the lining trolley and the tunnel wall, and the walking bracket 2.2 is first installed with the grinding mechanism 7. The walking bracket 2.2 moves along the length direction of the arc truss 1, from one end of the arc truss 1 to the other end, so as to perform the first circumferential grinding;

[0051] 2. After completing the first circumferential grinding, the lining trolley is driven by the driving assembly 4 to move a certain distance (the distance is less than the grinding width) toward the face, and the grinding mechanism 7 continues to grind in the circumferential direction until the entire plate surface of the steel mold 3 is polished; preferably, each ring overlaps a certain distance to ensure the grinding effect of the entire plate.

[0052] After grinding, the grinding mechanism 7 is disassembled, and the oiling mechanism 8 is installed on the traveling support 2.2; the oil in the oil tank 8.1 is pressurized by the booster pump 8.2, and then sprayed out through the oil pipe 8.3 to the nozzle, and the first circumferential oiling is started; the above steps 2-3 are repeated until the entire surface of the steel mold 3 is oiled. After grinding and oiling, the truss device is moved out of the steel mold 3 of the lining trolley to carry out the next process cycle.
