SLIT HOOD FOR DECREASING MICRO PRESSURE WAVES OF RAILROAD TUNNEL

摘要

PURPOSE: A slit hood for decreasing micro pressure waves of a railroad tunnel is provided to reduce noise pollution and vibration of the way out side of a tunnel due to micro pressure waves by decreasing micro pressure waves generated when a train approaches a tunnel. CONSTITUTION: The slit hood for decreasing micro pressure waves of a railroad tunnel comprises a pair of inclined plates projected to the front of a main body projected to a way in of a tunnel and provided with an opening having covers on both sidewalls, wherein the main body is formed to be 12.6 meters for a tunnel of the 0.75 kilometers class and the inclined plate is formed to have an angle of 45 degrees.
