Problems solved by technology

[0004] Sound barriers will be installed on the tracks when trains enter and leave culverts and pass through residential areas. Most of the existing sound barriers are non-closed sound barriers. Even if closed sound barriers are used, they will not be able to cope with the high-speed wind pressure generated when the train passes by. , just use a ventilation device with a single function to achieve the purpose of reducing the wind pressure

Abstract

The invention provides a closed tunnel structure sound barrier for overcoming defects existing in the prior art. The whole sound barrier is easy and rapid to install. By adopting a ventilation and noise reduction window shade, the wind pressure can be lowered, and the influence caused by noise on surroundings when a train passes can be lowered to the maximum extent; by adopting the technical scheme, the closed tunnel structure sound barrier comprises a steel support, a sound barrier unit, a laminated glass noise reduction barrier, an acrylic plate noise reduction barrier and a ventilation and noise reduction window shade, and the closed tunnel sound barrier is composed of a U-shaped structure formed by fixedly connecting the steel support, the sound barrier unit, the laminated glass noise reduction barrier, the acrylic plate noise reduction barrier and the ventilation and noise reduction window shade and a track foundation. The closed tunnel structure sound barrier is widely applied to the field of railroad bridges.

Description

technical field [0001] The invention discloses a closed tunnel structure sound barrier, which belongs to the technical field of railway bridges. Background technique [0002] Due to the rapid development of railways, the noise pollution generated during train operation has become more and more serious. In order to reduce the impact of railway noise, sound barriers are generally set up in places where residents live to cut off the transmission of noise. The investment of sound barrier project is appropriate, and the sound insulation effect is good, which has become an important measure to control traffic noise pollution. [0003] In the prior art, the railway sound barrier is composed of multiple sound barrier units in a certain order, and the sound insulation lining is also arranged inside the sound barrier unit shell, so as to further absorb sound energy and fundamentally prevent noise further spread to achieve the purpose of noise reduction. [0004] Sound barriers will...
