New mechanical joint segment tunnel lining system
After the Second World War, as the construction of the social infrastructure such as water supply and sewage systems, communication cables, railway and road networks advanced with urban sprawl, shallow underground installations have become congested, necessitating the use of greater-depth underground tunnels. To meet this change in construction environment, it has been developed a new one pass lining system. This is the world's first boltless, mechanical joint segment (NM segment) system, which strengthens tunnel lining materials, assures water-tightness and facilitates automatic segment assembly. Since the technical performance of NM segment was demonstrated in the Neyagawa a River Underground Diversion Construction Project, its application is expanding from rivers underground diversion to railway tunnels. This paper reports on the development of the NM segment structure and describes the performance evaluation based upon actual application.
