[0017] In order to prevent the silencer plate 2 from being separated from the guide rod 3 , a limiting platform 12 is fixed to the front end of the guide rod 3 .
[0018] When the utility model is in use, the base 9 is fixed to the roadbed of the road by bolts, and the bracket 10 is fixed to the roadbed, which effectively ensures the stability of the support plate 1, and then the support plate 1 is fixed to the roadbed on both sides of the road, the front side of the support plate 1 faces the road, and the rubber plate 6 is fixed in the groove 5 of the sound-absorbing plate 2 by screws 11, and a sound-absorbing sponge 7 is pasted on the rubber plate 6, and the sound-absorbing wedge 8 on the surface of the sound-absorbing sponge 7 faces the road. The sound-absorbing wedge 8 is a specially designed sound-absorbing structure, which is mainly used to eliminate noise. Its working principle is mainly based on the reflection and scattering characteristics of sound waves between air and materials. It has a sound-absorbing body with a very high sound absorption coefficient. When a large amount of noise is generated on the road, the sound-absorbing wedge 8 is the first to absorb the noise. , and under the action of the sound-absorbing sponge 7, the noise reduction effect is further optimized. The noise will produce a certain vibration. The sound-absorbing sponge 7 drives the sound-absorbing plate 2 to vibrate, and under the action of the compression spring 4, the impact of the sound-absorbing plate 2 on the supporting plate 1 is effectively alleviated.
