Abstract:

As a singlehole singleline tunnel of heavy haul railway, the Lianyunshan Tunnel on Menghua Railway is characterized by long deadend heading distance and small crosssection. With the interference of transportation during construction, it is sophisticated to achieve rapid construction. In order to realize rapid construction organization of singleline smallsection tunnel, the construction organization of tunnel excavation, inverted arch and secondary lining, construction machinery and equipment matching and excavation measures are studied, and based on which, the rapid construction of singleline superlong tunnel has been successfully realized. The results can provide reference for similar projects in the future.

Key words: heavy haul railway, single line superlong tunnel, small crosssection, equipment matching, construction organization, rapid construction
