PURPOSE: A construction method of an underground vertical structure is provided to construct the underground vertical structure consecutively and rapidly by implementing 'a stepwise ground excavation process at underground' and 'a stepwise wall structure molding process at the ground' at the same time. CONSTITUTION: A construction method of an underground vertical structure is as follows. 'A stepwise ground excavation process at underground', 'a slope protection and arrangement process of the excavated ground', 'a stepwise wall structure molding process at the ground', and 'a steam curing process' are implemented at the same time. One end fixed on an earth anchor formerly buried in the ground is connected to the other end of a pulling unit. The pulling unit is operated, and then the underground vertical structure is gradually dropped to a set depth of underground. |
