Abstract

The invention relates to a high-speed train tunnel exit denoising structure, comprising a denoising cover; the front end, rear end and lower end of the denoising cover are not sealed; the lower end ofthe denoising cover is buried in a foundation; the front end or rear end of the denoising cover encloses a tunnel exit or entrance; the front end or rear end of the denoising cover is connected withsurrounding rock at the tunnel exit or entrance; a sound-absorbing structure is arranged on the inner side of the denoising cover. The high-speed train tunnel exit denoising structure is simple in structure, reasonable in design and low in construction cost; local structure modifications are provided to reduce sound wave energy and propagation distance; the problem can be effectively solved that the tunnel exit and entrance have high noise.

Description

technical field [0001] The invention relates to a noise reduction structure at the exit of a high-speed rail tunnel, belonging to the field of noise reduction for high-speed rail trains. Background technique [0002] High-speed rail trains make a lot of noise when they enter and leave the tunnel entrance at high speed. At present, the impact on surrounding residents is generally reduced by fully sealing the sound barrier or laying sound-absorbing materials inside the tunnel. However, the cost is high and it is not suitable for large-scale promotion. Contents of the invention [0003] The invention proposes a noise reduction structure at the exit of a high-speed rail tunnel. [0004] The solution adopted by the present invention to solve the technical problem is that a high-speed rail tunnel exit noise reduction structure includes a noise reduction cover, the front end, rear end, and lower end of the noise reduction cover are not closed, and the lower end of the noise redu...
