The present invention relates to a tunneling methods and, particularly to installing an internal or external pre-support member along with a post support member and an apparatus therefor. The tunneling method includes: excavating a pilot tunnel in a main tunnel to be built; radially forming a drilled hole from an excavation surface of the pilot tunnel to a tip end of an internal pre-support member of the main tunnel at locations in the pilot tunnel; inserting the internal pre-support member into the drilled hole, and conducting grouting and fixing the internal pre-support member; excavating the tunnel along an excavation line of the main tunnel and spraying shotcrete to an excavation surface of the main tunnel; installing a post-support member between internal pre-support members in the excavation surface of the main tunnel; and connecting the internal pre-support member and the post-support member with a plate type support member.

An auxiliary tunneling apparatus includes a reaction force receiver and first and second split components. In the excavation of a second tunnel by a boring machine, the reaction force receiver forms a replacement face of a side wall of the second tunnel on a first tunnel side where the first and second tunnels intersect each other, and a gripper of the boring machine pushes against the replacement face. The first and second split components are installed to push against the side wall of the first tunnel, support the reaction force receiver within the first tunnel, and move back and forth with respect to the side wall of the first tunnel.
