[0002] With the development of society, cars and trains are the most commonly used means of transportation for people at this stage. Cars and trains will generate great noise during operation. In order to reduce the impact of concrete bridge noise on the surrounding environment, people usually install sound insulation barriers on both sides of the concrete bridge to reduce noise, prevent noise pollution and improve the environmental quality along the line.

[0003] Existing sound barriers are generally installed on both sides of concrete bridges through multiple connected sound barrier units. For concrete bridges with fences on both sides, a base is generally provided at the bottom of the sound barrier unit, and the sound barrier unit is fixedly installed on the top of the fence through the base. Since the thickness of the fence generally has certain differences during the construction process, if the sound barrier unit is installed on the fence of the entire road or bridge, the fence in some areas will have a gap between the base of the installed sound barrier unit and the fence or cannot be installed due to their different thickness, making the installation of the sound barrier unit very difficult. In the case of a gap between the base of the sound barrier unit and the fence, the wind resistance of the sound barrier unit will be weak and the strength will not meet the engineering requirements.

[0004] In response to the above problems, an innovative design was carried out based on the original sound insulation screen installation base. Utility Model Content
