PURPOSE: A construction method of a two arch tunnel with a shotcrete construction method are provided to reduce the construction periods of an entire two arch tunnel by reducing the construction periods of the center support wall.;CONSTITUTION: A pilot tunnel is excavated, and shotcrete is constructed in a position corresponding to one side of a center support wall around the center of the pilot tunnel. Quick concrete is sprayed on the constructed shotcrete so that the center support wall is formed. A main line tunnel is excavated to both sides of the pilot tunnel after the concrete is hardened into a predetermined intensity. A shotcrete member uses a waveform steel plate, and the steel plate is vertically and partially separated in order to improve workability.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Construction period; (BB) Construction step; (CC) Excavate a pilot tunnel(S11A); (DD) Install a center support wall(S11B); (EE) Excavate a main line tunnel(S11C)
