TUNNEL LINING STRUCTURE USING SHEET STEEL JOINED WITH STUD BOLT AND THE CONSTRUCTION METHOD |
摘要 |
PURPOSE: A tunnel lining structure using a sheet steel joined with a stud bolt is provided to secure structural safety by minimizing the relaxation of ground, to prevent accidents caused by the falls of bedrock and to improve working environment. CONSTITUTION: The tunnel lining structure(10) using a sheet steel joined with a stud bolt comprises: many curved sheet steels(11) joined with stud bolts(12), wherein an internal wall of a tunnel is formed by arranging many sheet steels(11) to be overlapped mutually while the stud bolts(12) face a shotcrete layer(14) and bolting up the overlapped sheet steels(11); a shotcrete layer(14) placed directly on the surface of footing bedrock(13); and a plain concrete layer(15) back-filled between the sheet steel(11) and the shotcrete layer(14).
