Abstract The paper introduces mainly the Songhe single line extra-long railway tunnel on Shui-I3ei Railway carrying out vigorously the mechanization of construction to implement the full face single-end rapid tunneling technique. It is expounded emphatically that the mechanization of construction is the best method and efficient means to implement the rapid tunneling for single line extra-long railway tunnels. The key and guarantee role to implement rapid tunneling by following measures are also expounded: to put forward the advanced installation of machinery and the optimized complete set of machinery, as well as how to enhance the machine management in site in the later stage of construction. The methods, experiences and obtained good effects in practices are also introduced for the complete sets of the machinery installations and their management, the construction organization, the technical measures, etc. Several suggestions concerned with to carry out vigorously the mechanization and to put forward the way for mechanized rapid construction are also proposed.
