The present invention relates to a method for constructing an underground vertical concrete structure by a top-down method unlike the existing method for constructing an underground vertical concrete structure from the bottom part to the upper part, and specifically to a method for constructing an underground vertical structure having multiple stacked segments by installing a circle-shaped steel end tip shoe in preliminary excavation after preliminarily excavating the ground with an excavator without constructing a temporary structure forming a retaining wall, installing concrete segments in a circle in the upper part of the steel end tip shoe as excavating with an excavator from the upper part of the ground to the lower part after installing a plurality of hydraulic devices and an electrically controlling hydraulic controller on the backside of a preliminary excavation surface, and press-constructing the concrete segments toward the lower part under the ground using a pressing hydraulic controller. |
