In the embodiment, the vertical hollow pressure relief channel 3 is arranged in the middle of the screen board, the air discharging holes 7 are respectively arranged on the board surfaces of the two sides of the upper end and the lower end of the pressure relief channel 3, the asymmetrical air discharging holes 7 and the sound absorption material in the pressure relief channel 3 can effectively ensure the acoustic noise reduction effect, and meanwhile, certain ventilation and pressure relief effects are also ensured.
Specifically, when a high-speed train, a train or an automobile enters a fully-closed tunnel constructed by the barrier plates, air in the tunnel is pushed by the high-speed vehicle to be discharged outwards through the pressure relief channels 3 in the barrier plates, otherwise, when the high-speed vehicle leaves the tunnel, outside air enters inwards through the pressure relief channels 3 in the barrier plates, and therefore the air pressure in the tunnel can be adjusted, and the effects of ventilation, pressure relief and leveling are achieved.
Meanwhile, the air discharge holes 7 corresponding to the ventilation areas 6 are formed in one side of the upper end of the pressure relief channel 3 and the other side of the lower end of the pressure relief channel 3, the vertical heights of the air discharge holes are asymmetrical, and sound absorption materials are uniformly distributed on two sides in the whole pressure relief channel 3, so that the acoustic noise reduction effect in the process that high-speed vehicles drive in and drive out of the totally-enclosed tunnel can be effectively guaranteed.
