The method according to any one of claims 1 to 10, When the inner wall structure is formed in the excavation space in which the provisional equipment is installed, the at least one formwork comprises a first formwork spaced apart from the temporary installation by a thickness of the inner wall structure comprising a first form. The method according to any one of claims 1 to 10, The at least one formwork wall structure forming apparatus comprising an inner and outer formwork, respectively located on the inside and the outside of the structure at a predetermined interval by the thickness of the structure. The method according to any one of claims 1 to 10, And a steam curing unit for supplying steam to the structure to promote steam curing. In claim 13, The steam curing unit A curing cover covering the formwork and the structure; A vapor pipe located within said curing cover; And And a steam source for supplying steam to the steam pipe. The method according to any one of claims 1 to 10, The formwork is a wall structure forming apparatus having a cylindrical shape. A method of constructing an underground vertical sphere structure using a wall structure forming apparatus according to any one of claims 1 to 10, A ground excavation step for forming an excavation space for installing the underground vertical sphere structure; A provisional installation step of installing a provisional facility to support the excavation space; A mold installation step of installing the formwork of the wall structure forming apparatus so as to be spaced apart from the provisional facility by a predetermined interval corresponding to the thickness of the inner wall structure in the excavation space in order to form the inner wall structure in the inner excavation space of the temporary facility; A concrete material input step of inserting a concrete material for forming an inner wall structure in a space between the temporary facility and the formwork of the wall structure forming apparatus; A formwork removing step of removing the formwork from the cured concrete using a detachable unit of the wall structure forming apparatus after the curing process of the concrete; A forming apparatus upward movement step of moving the wall structure forming apparatus upward after the formwork is removed; And And repeating the forming apparatus upward movement step from the formwork installation step so as to continuously mold the inner wall structure on the top, and The formwork removing step Lifting step of providing the lifting force to the formwork to lift the formwork; And Underground vertical sphere structure construction method comprising the step of retreating toward the form fixing beam of the detachable unit while the formwork is circular motion by the lifting force and the connecting bar of the detachable unit during the lifting step. A method of constructing an underground vertical sphere structure using a wall structure forming apparatus according to claim 13 or claim 14, A ground excavation step for forming an excavation space for installing the underground vertical sphere structure; A provisional installation step of installing a provisional facility to support the excavation space; In order to mold the inner wall structure in the inner excavation space of the temporary facility, while installing the steam curing unit of the wall structure forming apparatus to install the formwork of the wall structure forming apparatus spaced apart from the temporary facility by a predetermined interval corresponding to the thickness of the inner wall structure Steam curing unit and formwork installation step; A concrete material input step of inserting a concrete material for forming an inner wall structure in a space between the temporary facility and the formwork of the wall structure forming apparatus; A steam curing step of performing steam curing using the steam curing unit of the wall structure forming apparatus; A formwork removing step of removing the formwork from the cured concrete using a detachable unit of the wall structure forming apparatus after the steam curing process of the concrete; A forming apparatus upward movement step of moving the wall structure forming apparatus upward after the formwork is removed; And And repeating the forming apparatus upward movement step from the steam curing unit and the formwork installation step so as to continuously mold the inner wall structure on the top, and The formwork removing step Lifting step of providing the lifting force to the formwork to lift the formwork; And And the formwork is retracted toward the formwork fixing beam of the detachable unit while the formwork is circularly moved by the lifting force and the connecting bar of the detachable unit while the lifting step is performed.
