s5, reversely starting the positioning assembly to drive the two symmetrical butt joint plates to slide back to back along the telescopic plate so as to increase the distance between the two butt joint plates, and separating the positioning assembly and the butt joint plates from the bridge and the other bridge body so as to detach the bridge butt joint positioning device.
10. The method according to claim 9, wherein before step S4, the butt joint surface of the bridge and the other bridge needs to be horizontally detected, if the butt joint surface of the bridge and the other bridge is found to be non-horizontal, then the feeding assembly needs to be started to feed the butt joint surface so as to horizontally, and then step S4 and step S5 are performed to complete the bridge butt joint construction.
