Abstract：
The segment erector is a machine used to erect the circular lining segment of pre-cast concrete in the tunnel excavation process. It is difficult, however, to change the tail-seal brushes in a long distance tunnel. Based on the analysis of its working principle, structure and function, this paper proposes a segment erector that could rotate in all directions with the segment capable of moving within the scope of 6 degrees of freedom. Additionally, the strength of the key components is verified by FEM.
