Noise reduction barrier for road

The utility model discloses a noise reduction barrier for a road, which comprises a sound insulation barrier, the outer surfaces of the two sides of the sound insulation barrier are fixedly connected with barrier mounting frames, the two sides of the outer surface of the lower end of each barrier mounting frame are fixedly provided with mounting bases, and a plurality of groups of noise reduction mechanisms are arranged in the sound insulation barrier in a movable penetrating manner. According to the noise reduction barrier for the road, the noise reduction effect of the whole barrier is better through the arrangement of the noise reduction mechanism, the noise reduction effect is achieved through the arrangement of the first noise reduction inner holes, the second noise reduction inner holes, the first honeycomb noise reduction plate, the noise reduction holes and the inner plate noise reduction holes, and the noise reduction effect is achieved through the arrangement of the first noise reduction inner holes
