The present invention provides a vertical core-type underground structure construction method. According to the present invention, a vertical core-type structure can be safely constructed upward, regardless of a narrow construction space, in an underground roof structure where a slab pipe is installed. A preferred embodiment of the vertical core-type underground structure construction method according to the present invention includes a step in which a wall trench is formed through primary vertical drilling from the ground to a required depth and a PC panel is supported on a wall surface; a step in which a wall structure is primarily constructed through rebar distribution and concrete placement and curing in the primarily formed wall trench; a step in which a wall trench is formed through secondary drilling symmetrical to the primary drilling and a PC panel is supported on a wall surface of the wall trench; a step in which a wall structure is secondarily constructed through rebar distribution and concrete placement and curing in the secondarily formed wall trench; and a step in which a temporary girder for PC panel support is disassembled and a vertical passage is obtained. |
