Description
Technical Field
The utility model relates to a two lining platform trucks, in particular to can be under construction two lining platform trucks in tunnel gradual change cross-section belongs to tunnel construction technical field.
Background
When a train enters the tunnel at a high speed, the air in the tunnel is extruded due to the impact of the high speed on the air in the tunnel, so that high pressure waves are easily generated and transmitted to the downstream in the tunnel at the sonic speed, and the air in the tunnel is extruded to generate a flow velocity, thereby forming a piston effect in the tunnel. When the high-pressure wave is transmitted to the downstream exit of the tunnel and rushes out of the tunnel entrance, the high-pressure wave is converted into a micro-pressure wave due to the suddenly wide space outside the tunnel, and the micro-pressure wave may generate an unpleasant micro-pressure wave noise. In order to reduce the high pressure wave generated when the train enters the tunnel and reduce the micro pressure wave noise at the downstream tunnel entrance, the tunnel entrance is designed into a tapered shape, such as a trumpet shape, which is helpful to reduce the micro pressure wave noise.
