Abstract:
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.

Claim (Index 4):
The tunneling method of  claim 1 , wherein in inserting and installing the internal pre-support member in the drilled hole, the internal pre-support member is mounted with a stopper for preventing slip in the drilled hole, a discharge hose and an injection hose are bound to a side surface of the internal pre-support member, a packer for pressurized-grouting is mounted at a tip end of the internal pre-support member of the inner side of the tunnel, the internal pre-support member is inserted into the drilled hole for the internal pre-support member in the original ground of the main tunnel from the pilot tunnel by connecting a connection pipe to the internal pre-support member so that an end part of the internal pre-support member is partially exposed to be connected to the plate type support member at a planned excavation surface of the main tunnel, and then the connection pipe is removed, and the packer is expanded to conduct the grouting and perform curing to thereby connect the internal pre-support member with the plate type support member.
