제목대심도터널(Deep underground tunnels)
국가철도공단은 우수한 터널 건설 노하우를 통해 도시 중심부를 통과하는 보다 편안한 통로를 제공합니다.
From shallow tunnels lying close to surface of the earth to medium depth tunnels and beyond to deep subsurface tunnels, we have the experience and knowhow to take advantage and make use of spaces underground.
We will build tunnels that overcome the serious issue of our cities, urban overcrowding, to provide a more comfortable passageways through our urban centers.
