Description

Technical Field

[0001] The present invention relates to a diversion ventilation sound absorption and isolation barrier structure, and specifically belongs to the technical field of sound barriers. Background Art

[0002] Due to the rapid development of railways, the noise pollution generated during the operation of trains has become increasingly serious. In order to reduce the impact of railway noise, sound barriers are generally installed in places where residents live to cut off the noise propagation path. The investment in sound barrier projects is appropriate and the sound insulation effect is good, which has become an important measure to control traffic noise pollution. A sound barrier is a facility inserted between the sound source and the receiver, which causes a significant additional attenuation of sound wave propagation, thereby reducing the noise impact in a certain area where the receiver is located. With the rapid increase in infrastructure construction such as railways and highways in China and the gradual strengthening of people's awareness of environmental noise in daily life, the demand for sound barriers, as the most effective means to improve noise impact, is also increasing day by day. However, in the face of some extreme windy weather conditions and the shock waves of high-speed trains, the damage of the sound absorption screen body, steel columns and bridge concrete foundations of sound barriers is not uncommon. To address the above problems, the present invention provides a diversion ventilation sound absorption and isolation barrier structure, which has the functions of sound absorption, isolation, diversion and ventilation, and can reduce the force on the steel column structure and bridge foundation structure during large impacts such as high-speed train pulses and extreme winds.
