This means that the present invention has the function of quickly releasing the male and female joints from their positions. Step 7: The embedded nut is released from its position. The servo motor 501 drives the rotating shaft 502 to rotate, thereby driving the thread 505 to rotate and disengage from the embedded nut. At the same time, the second electric hydraulic cylinder 402 drives the second hydraulic telescopic rod 403 to slide and extend, thereby driving the insertion rod 504 to disengage from the side hole 205. This means that the present invention has the function of automatically releasing the embedded nut from its position. Step eight, the shield tunnel segments are taken out. The first electric hydraulic cylinder 301 drives the first hydraulic telescopic rod 302 to telescope and slide, thereby driving the top plate 303 to move linearly, and then the formed socket-type shield tunnel segments can be slid upward along the die groove 202, so that the shield tunnel segments can be taken out from the inside of the template. At the same time, the limiting rod 304 slides along the inner wall of the limiting hole 104 to ensure the stability of the linear movement of the socket-type shield tunnel segments, so that the present invention has the function of stably taking out the shield tunnel segments from the inside of the die groove 202.

The outer side wall of the male joint of the socket-type shield tunnel segment connector is wedged with the inner side wall of the positioning groove (602). The external locking bolt is then rotated along the locking threaded hole (603) to fix the male joint of the socket-type shield tunnel segment connector and the first positioning plate (601). The assembly between the male joint and the first positioning plate (601) is then moved and placed into the first groove (203). The external bolt is then rotated along the first through hole (606) and extended into the first threaded groove (604) to connect the first positioning plate (601) and the first connecting plate (605). This completes the positioning of the male joint of the socket-type shield tunnel segment connector. Step 2: Positioning the concave joint. The inner side wall of the concave joint of the socket-type shield tunnel segment connector and the outer side wall of the positioning protrusion (702) are wedged together to connect the concave joint with the second positioning plate (701). The combination of the concave joint and the second positioning plate (701) is then moved and placed into the second groove (204).

In this way, the spigot-type shield tunnel segment can be formed under the limiting action of the template (201), the top plate (303) and the limiting module (802). Then, the cover plate (801) can be separated from the open end of the mold groove (202) by holding the handle (805); Step six, the male joint and the female joint are released from their positions. By rotating the external bolt and disengaging the first threaded groove (604), the first positioning plate (601) and the first connecting plate (605) can be disengaged, thereby releasing the male joint from its position. Then, by rotating the external bolt and disengaging the second threaded groove (703), the second positioning plate (701) and the second connecting plate (704) can be disengaged, thereby releasing the female joint from its position. Step seven, the embedded nut is released from its position, and the servo motor (501) drives the rotating shaft (502) to rotate, thereby driving the thread (505) to rotate and disengage from the embedded nut. At the same time, the second electric hydraulic cylinder (402) drives the second hydraulic telescopic rod (403) to slide telescopically, thereby driving the insertion rod (504) to disengage from the side hole (205); Step eight, the shield tunnel segment is taken out, and the first electric hydraulic cylinder (301) drives the first hydraulic telescopic rod (302) to telescope and slide, thereby driving the top plate (303) to move linearly, and then the formed socket-type shield tunnel segment can be slid upward along the die groove (202), so that the shield tunnel segment can be taken out from the inside of the template. At the same time, the stability of the linear movement of the socket-type shield tunnel segment is guaranteed under the action of the limiting rod (304) sliding along the inner wall of the limiting hole (104).
