Abstract

The present invention relates to a protective structure for the mouth of an unfinished tunnel, which comprises a structure in which a scaffolding protective structure installed for protecting workers and construction equipment from falling rocks and soil at the mouth of the tunnel during tunnel excavation is not removed during the tunnel excavation work, which properly maintains the mouth of the tunnel, and which uses an external mold for reinforcing the unfinished tunnel. More particularly, steel ribs (20) are installed at equidistant intervals in the excavated tunnel (10) at the mouth of the tunnel, primary and secondary shotcrete (22) and (24) are sprayed on top of the steel ribs (20), a waterproofing material (30) is applied beginning from a shotcrete lining (14) of a pit (12) and extending across the primary shotcrete (22) of the excavated tunnel (10), and the primary shotcrete (22) surface of the excavated tunnel (10) is used as a mold in order to build an excavated tunnel concrete lining (16).
