In the present invention, concrete lining construction is simultaneously performed on the bottom of the tunnel and the circumference of the tunnel (sidewall and ceiling) in the process of tunnel excavation by TBM equipment (tunnel boring machine). Unlike the construction method in which the concrete lining work was sequentially carried out after excavation and penetration, the concrete lining can be placed at the same time as the excavation, so the work process can be shortened, so the construction period can be greatly reduced, thereby reducing the construction cost. It relates to a simultaneous construction method of concrete lining during tunnel excavation using TBM equipment that can obtain economical effects and increase work efficiency as well as structural stability.
