NON-EXCAVATION TUNNEL CONSTRUCTION METHOD AND NON-EXCAVATION TUNNEL CONSTRUCTION STRUCTURE CONFIGURED BY EXTRUDING PC STRUCTURE INTO STEEL PIPE

摘要

The present invention relates to a non-excavation tunnel construction method, and a non-excavation tunnel construction structure. Provided are the non-excavation tunnel construction method, and the non-excavation tunnel construction structure configured by extruding a PC structure into a steel pipe comprising: a first effect of enabling tunnel construction using only a steel pipe having a constant size; a second effect of handling a change in a width and the height of a tunnel; a third effect of reducing a construction period and construction costs; a fourth effect of removing problems caused by a construction error; a sixth effect of significantly reducing construction costs; and a seventh effect of significantly reducing the construction costs.;COPYRIGHT KIPO 2016
