The other is to pre-prepare several components in a factory or on site, transport them into the tunnel, and assemble them into a lining ring by machine. Prefabricated tunnel linings have many advantages: (1) Once assembled, they can withstand the pressure of the surrounding rock without curing time; (2) A large number of components can be mass-produced in factories and assembled mechanized, thereby improving working conditions and saving labor; (3) During assembly, temporary support such as arches and formwork is not required, thus saving a lot of supporting materials and labor; (4) The assembly speed is increased due to the use of mechanization, which shortens the construction period and may also reduce the cost; (5) Prefabricated linings have strong adaptability and can be used in some special environments such as high-altitude cold.
