Abstract:

The secondary lining of mined tunnel at present has many disadvantage, i.e. complicated process, slow construction schedule and bad forming quality. As a result, key assembling technologies for assembled segments in mined tunnels are introduced, and components and function of matching segment assembling equipment are introduced as well based on construction technology of shield mining method and segment assembling mechanism of EPB shield.

Key words: shallowcovered and mined tunnel, segment assembly, segment positioning, sealing waterproof
