Dual-mode(EPB/TBM)Shield Mode Conversion Technology Engineering Practice
The dual-mode shield tunneling machine is designed for shield tunneling projects with significant geological fluctuations.It adapts to the efficient construction and excavation of shield tunneling in different geological environments by switching the balance mode.The section between Pinghu railway station and Fenggang station of Shenzhen Huizhou Intercity Railway adopts EPB/TBM dual-mode shield construction because of the soft upper and hard lower geology in the front and rear sections,and the full section rock stratum geology in the middle section.The mode needs to be switched four times.This article systematically elaborates on the efficiency and safety of mode switching.
