Abstract

The invention relates to the field of buildings and discloses a sound insulation and noise reduction structure for effectively reducing the urban light rail traffic noise. The sound barrier structuresare additionally arranged at the two sides of a light rail, each sound barrier structure comprises two metal perforated plates, and the metal perforated plates are arc-shaped. The lower parts of thetwo metal perforated plates are respectively fixed on the light rail, and the upper parts of the two metal perforated plates are bent towards the light rail but are not connected with each other. Oneside, far away from the light rail, of one metal perforated plate is coated with a porous sound absorption material, and one side, far away from the light rail, of the other metal perforated plate iscovered with the green plants. The sound barrier structures are additionally arranged at the two sides of the light rail, and the sound waves can be absorbed or reflected through the sound barrier structures, so that the noise propagation is stopped.

Description

technical field [0001] The invention relates to the construction field, in particular to a sound insulation and noise reduction structure. Background technique [0002] Although the construction of light rail can promote urban development, the operation of light rail will cause noise disturbance to nearby residents. Contents of the invention [0003] The object of the present invention is to provide a sound insulation and noise reduction structure that can effectively reduce urban light rail traffic noise, so as to reduce the noise disturbance caused by light rail operation to nearby residents. [0004] A sound insulation and noise reduction structure for effectively reducing urban light rail traffic noise, characterized in that: sound barrier structures are added on both sides of the light rail; [0005] The sound barrier structure includes two metal perforated plates, the metal perforated plates are arc-shaped, the lower parts of the two metal perforated plates are resp...
