2 is a view for explaining a method of preventing diffusion of suspended matters through two air curtain apparatuses according to an embodiment of the present invention. 2, when a fire occurs in the vehicle 210 in the road tunnel 10, smoke or heat is sensed by the fire detection sensor 31, and the fire detection sensor 31 senses the sensing information To the server (80). The sensing information includes the sensing value and the identification information of the fire detection sensor 31. The control server 80 can grasp the fire occurrence point based on the identification information of the fire detection sensor 31 included in the sensing information and can detect a fire occurrence point of the pair of air curtain devices 60 And selects and controls the air curtain device (60).

The air curtain device 60 is provided with intake fans 61 on both sides facing the entrance and exit directions of the road tunnel 10 and an exhaust fan 62 on the lower surface facing the road. 2, the left air curtain device 60 controls the intake fan 61 so that air is sucked from the left side and the air curtain device 60 on the right side sucks air from the right side And controls the intake fan 61. The intake direction of the intake fan 61 of the air curtain device 60 on the left side and the intake direction of the intake fan 61 of the air curtain device 60 on the right side are opposite. In this case, floating matters such as dust and smoke due to the fire are positioned between the two air curtains formed by the pair of air curtain apparatuses 60. The air sucked from the outside through the intake fan (61) is discharged in the direction of the road through the exhaust fan (62) to make an air curtain.

On the other hand, the control server 80 controls the pump 40 to supply the water in the water storage tank 50 to the upper side railing 22 of the safety railing 20, which is installed from the entrance to the exit of the road tunnel 10.

The upper railing 22 is provided with a plurality of openings so that water is simultaneously sprayed in a plurality of openings to extinguish the fire area. When the fire is extinguished, the control server 80 moves the pair of air curtain apparatuses 60 so as to be close to each other. Therefore, floating matters such as smoke and dust generated by the fire are collected in the center. The control server 80 controls the distance between the pair of air curtain apparatuses 60 based on the value measured by the pressure measurement sensor 32. If the two air curtains are too close to each other, the pressure of the float increases, and the float may leak out of the air curtain. Preferably, the control server 80 causes the distance between the two air curtain devices 60 to be distanced when the pressure between the two air curtains is above the threshold value, and between the two air curtain devices 60 when the pressure is below the threshold value Make the distance closer.

When a fire occurs between the two air curtain apparatuses 60, the control server 80 detects at least one of the openings 311-313 of the intermediate railing 23 located between the two air curtain apparatuses 60 And controls the open / close valve of the opening of the valve. In this embodiment, the openings 312 are opened and the remaining openings 311 and 313 are closed. The control server 80 rotates the intake fans 321 and 322 located on the left side around the opened opening 312 so as to transfer the air to the left side, And the intake fans 323 and 324 located at the right side of the intake fan rotate to feed air to the right side. That is, the rotational directions of the left intake fans 321 and 322 and the rear intake fans 323 and 324 are opposite. If the direction of rotation is the same, the suction of the float from the open opening 312 is not achieved properly. When two or more openings are opened, the adjacent openings are opened and the direction of rotation of the intake fan on the left side of the open apertures and the direction of rotation of the intake fan on the right side are reversed.
