Road and bridge noise reduction device
The invention relates to the technical field of road facilities, in particular to a road and bridge noise reduction device which comprises a protective baffle, a plurality of noise reduction blocks and a fixing seat, the fixing seat is fixed to the lower side of a road surface, the noise reduction blocks are evenly connected to the front side of the protective baffle, and a connecting frame is arranged at the bottom of the protective baffle. The bottom of the connecting frame is connected with the fixing base in a sliding mode, and a supporting arm is arranged on the back of the protective baffle and is in a circular arc shape. The protective baffle is slidably connected with the fixing base through the connecting plate and the connecting base on the lower side, the fixing base and the pressing beam press and clamp the road surface, noise generated by a vehicle is absorbed and reflected through the noise reduction blocks on the inner side of the protective baffle, noise transmission is reduced, and the noise reduction effect of the protective baffle is improved.
本发明涉及道路设施技术领域，具体地说就是一种道路桥梁降噪装置，包括防护挡板、若干个降噪块和固定座，所述固定座固定于路面下侧，若干个降噪块均匀连接于防护挡板前侧，所述防护挡板的底部设有连接架，所述连接架的底部与固定座滑动连接，所述防护挡板背部设有支撑臂，所述支撑臂为圆弧形。防护挡板通过下侧的连接板和连接座与固定座滑动连接，固定座与压紧梁对路面进行压紧夹持，通过防护挡板内侧的降噪块对车辆产生的噪音进行吸收和反射，降低噪音的传播，提高防护挡板的降噪效果。
