Lying in a horizontal state, the first segment pedestal 34 faces upward in a vertical state. And, the second rotating frame 50 is located opposite to the first rotating frame 30, the second support body 52 is in the vertical direction toward the top, the second segment pedestal 54 is in a horizontal state Is lying down.

In the above state, the cured segment is removed and moved in a segment mold (not shown) through a ceiling crane facility (not shown). At this time, the inner surface of the segment suspended from the overhead crane equipment (outer surface of the tunnel wall) faces the floor. This is because when the segment is molded in the mold, its inner side remains intact toward the bottom.

As shown in FIG. 13, the second support of the second rotating frame 50 is caused by the continuous rotation of the second rotating frame 50 by the operation of the rods 82a and 82b of the second cylinders 80a and 80b. When the body 52 is kept horizontal with the base frame 10, the segment 100 is in a state supported by the second support body 52.

As the inner surface of the segment 100, which is the outer surface of the tunnel wall by the above operation, remains open toward the upper side, the operator can perform the machining operation by trimming the inner surface of the segment 100, or the like. do.

When the above operation is completed, the segment 100 is moved using a ceiling crane facility (not shown) and placed in a desired place.

6, the first rotary frame 30 and the second rotary frame 50 are placed in an initial standby state to prepare for the next work process.

On the other hand, in the above process, during the rotation operation of the first rotary frame 30 and the second rotary frame 50, each of the support body (32, 52) is a buffer member provided on the support piece (15, 19) ( In contact with 15a and 19a, the impact of each rotating frame is alleviated.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and it is common in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

As described above, the tunnel segment inverter of the present invention can prevent the safety accident of the operator by allowing the segment to be smoothly inverted without the help of the operator, and by shortening the working time due to the limited use of the ceiling crane equipment, The productivity of the segment can be improved, and the segment can be safely reversed without damaging the side edges of the segment.
