The present invention relates to a ventilation facility for safety maintenance of an underground tunnel facility. The ventilation facility is to provide pleasant environment for an underground tunnel facility by discharging air into the underground tunnel facility and supplying fresh outer air to the inside, provide a moving path in order for a worker to safety move, and prevent a cover from being collapsed by load transmission. According to the present invention, the ventilation facility for safety maintenance of an underground tunnel facility comprises: a ventilation duct (10) connected to the inside of the underground tunnel facility (1) and having an exhaust pipe connected to the upper side of the ground; a porous cover (20) connected to an upper opening part of the ventilation duct to be separated; and a strut pipe (30) installed in the ventilation duct in a vertical longitudinal direction and providing a ventilation path and a moving path to the inside and the outside. The strut pipe includes: a strut pipe main body (40) of which the upper and lower part are open to enable ventilation and movements of the worker; multiple struts (50) arranged in the vertical longitudinal direction at a fixed height from each other and formed to be symmetric around the strut main body on the circumference of the strut main body, wherein the end of the struts is anchored to the ventilation duct; a ladder (60) formed between the struts; and a guard protecting the worker using the ladder since one side of the guard is connected to the circumference of the strut main body to be folded by a hinge (73). |
