TBM 전방 스캐너{TBM Face Scanner}TBM Face Scanner {TBM Face Scanner}

본 발명은 TBM(Tunnel Boring Machine)의 헤드 전면부에 설치되는 영상센서를 이용하여 굴착면의 지반 상태를 화면으로 확인할 수 있는 TBM 전방 스캐너에 관한 것이다.The present invention relates to a TBM forward scanner capable of confirming the ground condition of an excavation surface on the screen by using an image sensor installed in a head front portion of a TBM (Tunnel Boring Machine).

터널 시공의 경우 사전 지반 조사를 통해서 전반적으로 주변 지반의 특성을 개략적으로 알 수 있으나 터널 사고에 밀접한 영향을 주는 터널 전방의 주변 지반 상태를 구체적으로 확인하기 위해서는 굴착면의 지층 형태 및 절리상태를 관찰하여 평가하는 방법이 사용되어야한다. 이러한 기술의 일환으로 터널의 막장을 촬영한 입체사진을 이용하여 막장에 분포하는 암반의 불연속면의 구조를 추출하는 "터널 막장의 불연속면 분포 조사 시스템 및 방법" 및 "디지털 이미지를 이용한 터널 조사 시스템 및 방법" 등이 개발되었다.In case of tunnel construction, the characteristics of the surrounding ground can be roughly known through the preliminary ground survey. However, in order to confirm the condition of the surrounding ground in front of the tunnel which closely influences the tunnel accident, A method of evaluation should be used. As a part of this technique, "Discontinuous surface distribution survey system and method of tunnel surface" and "Tunnel survey system and method using digital image" to extract the structure of discontinuity surface of rocks distributed in the tunnel surface by using three- "Was developed.

그러나 TBM 공법을 적용할 때는 터널의 굴착면을 장비의 면판이 막고 있기 때문에 상기의 방법들을 적용할 수 없다. 따라서 전기비전항 기법을 사용한 "TBM 터널 전방 예측 시스템 (특허출원번호 제 10-2011-0144919, 출원일: 2011년 12월 28일)" 등과 같은 간접적인 지반평가 기법이 개발되어 왔다. 그러나 이러한 물리탐사 방법으로는 굴착면의 상태를 직접 관찰할 수 없다는 한계가 있다.However, when applying the TBM method, the above methods can not be applied because the face plate of the equipment blocks the excavation surface of the tunnel. Indirect ground assessment techniques such as "TBM tunnel forward prediction system (patent application No. 10-2011-0144919, filed on Dec. 28, 2011)" using the electricity cost prior art technique have been developed. However, these geophysical methods have limitations in that they can not directly observe the condition of the excavation surface.
