Abstract

Abstract:

The arrangement of the conveyor belts, flexible ventilation ducts, water supply pipes and high voltage cables for West Qinling tunnel with belt conveyor mucking system, which is constructed by TBMs, is presented in the paper. The design of the fullface hydraulic lining formwork jumbo is described. The paper can be served as reference for similar projects in the future.

Key words: West Qinling tunnel, TBM, belt conveyor, full face hydraulic lining formwork jumbo, utility line arrangement, simultaneous lining
