A tunnel lining structure system using curved corrugated steel plates and consrution method therof

摘要

PURPOSE: A tunnel lining structure using a curved wavy steel plate is provided to secure structural safety by minimizing ground subsidence, to prevent the accident caused by the breakdown of bedrock and to improve working environment. CONSTITUTION: The tunnel lining structure using a curved wavy steel plate comprises the steps of placing a shotcrete layer(3) on the surface of footing bedrock(2) to stabilize the footing bedrock of an excavated tunnel, arranging curved wavy plates(50) having the thickness of a plate and the wavy shape corresponded to curvature of the excavated tunnel and planned load to be overlapped mutually, forming internal walls(5) fastened continuously by bolts toward the outside of the curved wavy steel plate(50), and placing a plane concrete layer(4) to a space between the shotcrete layer(3) and the internal wall(5).
