초록

본 논문은 shield TBM의 버럭 배토장비인 screw conveyor의 최적 버럭 배토효율에 관한 연구이다. screw conveyor의 배토효율에 영향을 미치는 주요 Parameter인 screw 형태(Shaft식, Ribbon식), screw conveyor와 screw 각도의 영향을 분석하기 위하여 축소모형시험을 실시하였다. 축소모형시험을 통해 구한 버럭 배토 효율과 기존 이론식을 통해 구한 최적의 버럭 배토효율을 비교 분석하여 최적의 screw 형태, screw conveyor와 screw각도를 도출 할 수 있었다. 결론적으로 축소모형시험을 통하여 screw conveyor 설계인자들에 대하여 제시하였다. 또한 이 연구 결과는 향후 shield TBM 기술을 발전시키는데 유용할 것으로 기대된다.

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.
