Noise reduction device for roads and bridges
The invention discloses a road bridge noise reduction device, which belongs to the technical field of bridges and roads, and comprises a fixed seat for fixing and supporting; the first end of the sound insulation plate is fixedly connected with the fixed seat, and the second end of the sound insulation plate is provided with a bending part which is bent towards the road direction; the sound absorption plate is located on one side of the road and slidably installed on the fixing base, and the sound absorption plate and the sound insulation plate are fixedly connected through a telescopic plate; a plurality of sound absorption holes are formed in the sound absorption plate; the sound absorption rubber plate is fixedly connected to the side, away from the sound insulation plate, of the sound absorption plate; and the weight increasing plate is fixedly connected to the lower end of the fixing base and fixedly connected with the outer surface of the bridge road, and the weight increasing plate is used for increasing the overall stability. The sound absorption plate is arranged on the side close to the road, and the sound insulation plate is arranged on the side away from the road, so that double sound reduction and sound insulation are achieved, and the noise reduction effect of the device is better.
本发明公开了一种道路桥梁降噪音装置，属于桥梁道路技术领域，其包括：固定座，用于固定支撑；隔音板，隔音板的第一端与固定座固定连接，隔音板的第二端具有向道路方向弯曲的弯折部；吸音板，吸音板位于道路的一侧，并可滑动地安装在固定座上，吸音板与隔音板之间通过伸缩板固定连接；吸音板设置有若干吸音孔；吸音橡胶板，吸音橡胶板固定连接在吸音板远离隔音板的一侧；增重板，增重板固定连接在固定座的下端，并与桥梁道路外表面固定连接，增重板用于增加整体的稳定性。本发明通过在靠近道路的一侧设置有吸音板以及在远离道路的一侧设置隔音板，实现双重降音隔音，使该装置的降噪效果更好。
