UNDERGROUND-STRUCTURE CONSTRUCTION METHOD
An underground-structure construction method of arranging an underground structure by causing drilling apparatuses engaged with a concrete-made closed-shaped bottom frame to travel in a reciprocating manner to drill a just-underground of a bottom part of the underground structure, discharging to an earth surface excavated earth and sand of an internal ground, and extending a building frame of an upper part of the underground structure includes: open-cutting a ground to form a larger-sized mortar-shaped working hole; forming a closed-shaped horizontal reference area in an edge ground; arranging a bottom frame on the horizontal reference area; building a first stage building frame on the bottom frame; and backfilling, with backfill soil, an annular-shaped outer space of inner and outer spaces as a result of dividing the working hole, the drilling apparatuses being caused to uniformly drill, from the horizontal reference area as a drilling initiation plane, the just-underground of the bottom part.
