The present invention relates to an overlapped lining segment and a pipe jacking method used for non-excavated construction for pipe type structures like a tunnel. The segment comprises an inner separating plate (10) having a plurality of protrusions and grooves (31, 32) on the outer surface at certain distances and an outer separating plate (20) having a plurality of the protrusions and grooves (31, 32) matching with the protrusions and grooves (31, 32) of the inner separating plate on the inner surface at the certain distances. The pipe type structure is complete d as the inner and outer separating plates (10, 20) are axially connected to each other in the process of tunneling. According to the invention, an underground pipe structure is quickly and stably assembled without additional coupling units, and the underground pipe structure includes deformed plates overlapped on each other so that structural stability is secured during the construction as well as after the construction. |
