Tunnel Segment Connection Device with Thread

摘要

The present invention relates to a device for interconnecting PC segments used in tunnel excavation, and since it is formed with a thread on the inner circumferential surface of the socket, it is possible to achieve the effect of easy separation from the mold after the socket is injected. In addition, since the diameters of the male thread of the centering pin and the female thread of the socket are different from the midpoint, it is possible to achieve the effect of facilitating the mounting of the centering pin.
