Abstract

TBM disc cutter, which is the main cutting tool of tunnel boring machine (TBM), is replaced when it is excessively worn during the boring process. Disc cutters are usually monitored by workers at cutterhead chamber, and they check the status and wear amount of cutters. Because cutterhead chamber is usually in dangerous circumstance due to high pressure and instability of excavation surface, the measurement by manpower occasionally results in inaccuracy of measurement result. In order to overcome the limitations, the real-time disc cutter monitoring techniques have been developed in some foreign countries. This paper collected the current status of disc cutter monitoring system from the literature. Several types of sensors are used to measure the cutter wear, and it is believed that the collected information can be useful reference when similar domestic technologies are developed in the future.

TBM의 주요 절삭도구인 디스크커터는 과다하게 마모되거나 손상된 경우 적절한 시기에 교체되어야 한다. 일반적으로 커터의 교체여부를 판단하기 위해서 작업자가 커터헤드 챔버의 내부로 접근하여 디스크커터의 상태와 마모량을 계측하고 있다. 하지만 커터헤드(cutterhead) 챔버(chamber) 내부는 작업자에게 열악한 조건일 경우가 많아 작업자의 안전과 관련한 이슈가 있으며, 인력에 의해서 계측이 이루어짐에 따라 계측치의 오차도 발생하는 것으로 보고되고 있다. 이러한 한계점을 극복하고자 현재 해외에서는 디스크커터의 마모정도를 계측센서를 통해 굴착 중에 실시간으로 측정하기 위한 기술의 개발이 활발하게 이루어지고 있으며, 본 연구에서는 현재까지 해외의 문헌을 통해 보고되고 있는 TBM 디스크커터의 마모량 계측에 관한 연구현황에 대하여 소개하고자 하였다. 여러 형식의 센서가 디스크커터의 마모계측을 위해 활용되고 있으며, 향후 국내에서도 유사한 기술의 개발이 이루어지는 경우에 유용한 참고자료가 될 수 있을 것으로 판단된다.
