Abstract

Continuous excavation technologies are developed to improve the excavation rate of shield TBM. Continuous excavation is a technology that provides thrust to segments, excluding being installed one, to reduce tunneling downtime. This paper investigated the prior technology related to continuous excavation segments. The main technology was classified into helical segment, honeycomb segment, and conventional segment methods. The helical segment method has not been applied in actual construction yet, and the honeycomb segment method has not succeeded in commercialization. The continuous excavation method using conventional segments has been successfully demonstrated. The thrust force and operation method of the thrust jacks for the semi-continuous technology were analyzed. Continuous excavation TBM research is also progressing in Korea, and through the analysis of successful cases, the need to develop independent continuous excavation methods has been identified.

TBM의 실굴진율을 향상시키기 위한 연속굴착 기술들이 개발되고 있다. 연속굴착은 설치중인 세그먼트를 제외한 나머지 세그먼트에 추력을 가해, 굴진 정지 시간을 줄이는 기술이다. 본 기술보고는 연속굴착 세그먼트에 관한 선행기술을 조사하였다. 주요 선행기술을 헬리컬 세그먼트, 육각형 세그먼트, 기존 세그먼트 방법으로 분류했다. 헬리컬 세그먼트 방법은 아직 시공사례가 없으며, 육각형 세그먼트 방법은 상용화에 성공하지 못했다. 기존 세그먼트를 이용한 연속굴착 방법은 실증에 성공했다. 해당 기술에 대한 추진잭 추력, 운영방법을 분석했다. 국내에서도 TBM 연속굴착 연구개발이 진행 중이며, 성공사례 분석을 통해 독자적인 연속굴착 방법이 개발되어야 할 것으로 판단된다.
