When the tunnel segment clamping device is used, a tunnel segment to be machined is placed in the connecting frame 343 through the matching of the mechanical arm 2 and an operator, and is clamped through the clamping plate 345. Bolt 3413 is then rotated until bolt 3413 is inserted into receptacle 3416 to complete the fastening. And then starting the first motor 16 to enable the rotating part 33 and the overturning clamping mechanism 34 to rotate, enabling the orientation of the connecting frame 343 of the overturning clamping mechanism 34 to be unchanged during rotation, keeping the first motor 16 started after the tunnel segment is completely installed in the overturning clamping mechanism 34, starting the booster pump 46, simultaneously starting the second motor 412 and the third motor 418, and adjusting the position of the spray head 422 until one side of the tunnel segment is uniformly sprayed with the anticorrosive paint.

Booster pump 46, second motor 412 and third motor 418 are then turned off and bolts 3413 are reversed to release the tunnel segment from the fixture, and handwheel 348 is then turned to rotate the tunnel segment 180 deg., and bolts 3413 are turned to secure the tunnel segment. And then starting the booster pump 46, the second motor 412 and the third motor 418 again, and uniformly spraying the anticorrosive paint on the other surface of the tunnel segment. And finally, taking down the sprayed tunnel segment.
