- W2472783240 abstract "본 연구에서는 쉴드터널의 볼트 체결 방식의 문제점을 개선하기 위해 강연선 긴장력을 이용한 새로운 세그먼트 체결 기술을 개발하였다. 현장 조립 시험시공을 통해 세그먼트 전단키가 세그먼트 틸팅 공정에서 가이드 역할을 하여 볼트 체결 방식보다 조립 시간이 더 단축되는 것을 확인하였다. 그리고 세그먼트 조립 공정의 소요공기 측정결과 볼트 체결 방식은 1개의 세그먼트 공급에서 체결까지 420초가 소요되었고, 강연선 체결 방식은 400초가 소요되었는데, 강연선 자동화 장치를 이용할 경우 기존 볼트 체결 방식에 비해 60초의 소요공기 감소효과가 있는 것으로 나타났다. 또한, BIM을 활용한 쉴드TBM 연동 강연선 자동화 시스템 모델링은 쉴드TBM 설계, 굴진 계획, 공법 프로세스 파악, 시공 관리 등에서 효과적으로 활용될 수 있을 것으로 판단된다. In this study, the new segment assembling method using cable tensible force was developed to improve the problem of bolt assembling method of shield tunnel. In the field test construction, cable assembling method reduced the assembling time of segment in comparison with bolt assembling method because of guide role of segment shear-key. In the result of measuring the necessary time for segment assembling process, it took 420sec to assemble one segment in bolt method and 400sec to assemble one segment in cable method, but in case of using the cable automatic feeder, it could reduce the necessary time as 60sec in comparison with bolt assembling method. The cable automatic system modeling using BIM, that connected shield TBM also will be utilized in the area of design TBM, excavation plan, method process understanding, construction management and so on." @default.
