Abstract:

Based on No.07 Bid Section of West Extension Line of Beijing Metro Line No. 6, the composition and function of the assembling equipment for fabricated lining are introduced. The application of the new type of fabricated lining technology to the project is presented in detail. The characteristics of the new type of fabricated lining technology and its supporting equipments are summarized. The study results show that, by using the fabricated segment assembly equipment: (1) the tunnel construction quality can be ensured; (2) the construction schedule can be shortened, and the construction personnel can be reduced by more than 2/3; (3) small vertical launching can be realized, and the mechanization and automatization level can be improved; (4)the new type of fabricated lining technology needs to be further improved and popularized.

Key words: fabricated lining, segment assembly, metro tunnel, shield method, shallowburied and mining method
