INCLINED SHAFT STRUCTURE TO CONVERT AIR DIRECTION

摘要

The present invention relates to a structure for changing a direction of air supply and exhaust in an inclined shaft of a tunnel which comprises: a horizontal panel installed in a transverse panel of a quarterly-divided or horizontally half divided duct installed in an inclined shaft connection unit; a vertical panel installed in a longitudinal panel of a vertically half divided duct installed in the back of the quarterly-divided or horizontally half divided duct; and a direction change panel of which one end of a front is installed in one end of the horizontal panel of which one end of a back is installed in one end of the vertical panel of which an other end of the front is installed in the other end of the horizontal panel of which the other end of the back is installed in the other end of the vertical panel, and which is gradually twisted to make the up-and-down divided internal space of the inclined shaft divided in the horizontal panel to be left and right divided in the vertical panel. According to the present invention described above, by changing the direction of air supply and exhaust after the inclined shaft connection unit to the left and right, space utilization of the inclined shaft and efficiency in maintenance of the tunnel using the inclined shaft is improved. Moreover, the present invention enables construction of the entire part of the inclined shaft with vertically half divided ducts, facilitating evacuation through the inclined shaft in case of an emergency.
