[0002] Some highways and elevated roads use bridges when passing through urban areas. By building bridges, the way of not affecting urban buildings is realized, so that vehicles can directly and effectively pass through urban areas. However, since a large amount of noise will be generated during the driving of vehicles, generally sound insulation screens will be installed on both sides of the bridges passing through urban areas to avoid noise pollution caused by vehicle driving noise to urban areas.

However, most of the existing sound insulation devices are of an integral structure. When a part of them is damaged by external force, the whole needs to be replaced, resulting in a large maintenance cost and low replacement efficiency. To solve the above problems, a sound insulation device for a high-speed bridge is proposed. Content of the Utility Model
