The present invention relates to a construction method of an air duct structure for tunnel ventilation. Provided is the construction method of the air duct structure for tunnel ventilation includes: a support fixating step of fixating a support to at least one lateral wall between lateral walls of a part of a passage inside a tunnel in a longitudinal direction; a supporting member lifting step of lifting a supporting member used for forming an air duct in an upper side and the passage in a lower side higher than the supporter at a position separated from the supporter after the supporting fixating step; and a supporting member placing step of placing the supporting member on the supporter by moving the supporting member downward after positioning the supporting member in an upper side of the supporter by moving the supporting member in a horizontal direction. The construction method of the air duct structure for tunnel ventilation facilitates the construction of the air duct structure by remarkably reducing time required for the construction process and simplifying the construction process in comparison with an existing method by horizontally and vertically moving the supporting member without a step of horizontally rotating the supporting member when installing the supporting member at a desirable height. |
