Abstract
This paper presents the screw conveyor operation efficiency of shield TBM in soft ground. In order to study the screw conveyor operation efficiency, the experimental and theoretical studies were carried out. In experimental study, the operating amounts of muck were examined and compared due to the screw conveyor operating parameters including types (Shaft and Ribbon screw), angles of screw and conveyor. The results obtained from the laboratory model tests were analysed and evaluated to suggest the most suitable muck operating parameters during the shield TBM tunnelling in soft ground. In conclusion, it is found the operation parameters to increase the screw conveyor efficiency. In addition, the information presented in this paper may be useful for developing the design technology of shield TBM in the future.
