🗝️지식인 + : https://bit.ly/EBSKnowledge 사람과 세상을 이어주는 공간, ‘터널’에 대해서 탐구한다. 무심히 지나쳤던 터널에는 소통을 위한 최첨단 과학이 숨겨져 있다. 지하철 분당선 한강하저터널, 5.1km로 국내에서 가장 긴 도로터널로 기록될 강원도 배후령 터널의 공사 현장, 독일의 TBM(Tunnel Boring Machine)제조 회사, 알프스 산맥을 뚫고 있는 터널 공사 현장 취재를 통해 터널굴착 과학기술의 현재와 발전 가능성을 알아본다. 한강하저터널의 실드 TBM(Shield Tunnel Boring Machine)는 직경 8m, 무게 650톤의 초대형 터널 굴착 기계로 우리나라에서 사용중인 TBM중 가장 큰 것이다. 연약한 지반이나 한강하저와 같은 수압이 강한 곳에 적합한 터널 굴착 장비다. 강원도 배후령 터널의 공사 현장에 있는 TBM은 산악지형에 적합한 굴착기계로 화강암과 같은 단단한 암석도 뚫어내는 기계다. 배후령 터널 공사현장의 막장에 들어가 TBM이 뚫은 화강암 암반 단면을 국내 최초로 공개한다. 또한 찬반양론이 있는 한반도대운하, 이 가운데 한강과 낙동강을 이어줄 조령산터널의 수위차 극복을 위한 모델로 알려진 벨기에 스트레피-티유(Strépy-Thieu) 선박용 리프트의 작동 모습을 TV로는 국내 최초로 공개한다. 스트레피-티유(Strépy-Thieu) 리프트는 벨기에 중앙운하의 수위차를 극복하기 위해 73m를 오르내린다. 📺방송정보 📌프로그램명: 다큐프라임 - 원더풀 사이언스 '소통의 길, 터널' 📌방송일자: 2008년 4월 3일 #EBS #지식 #EBS지식 #과학 #다큐프라임 #원더풀사이언스 #과학다큐 #과학다큐멘터리 #다큐멘터리 #터널 #터널공사 #배후령터널 #TBM #공사 #건설 #건축 #굴착기
