The traditional sound barrier mainly includes fully enclosed sound barrier, semi-enclosed sound barrier and upright sound barrier. The traditional sound barrier is installed on the fence on both sides of the track, and has the problems of complex structure, large weight and volume, large space occupation, large construction and installation difficulty, poor landscape, high investment and the like. Research shows that the wheel-rail noise at the lower part of the train accounts for about 80% of the urban rail transit noise. In order to improve the noise propagation efficiency of the sound barrier and minimize the distance between the sound barrier and the track, the sound energy is eliminated in the space formed by the sound barrier, the car body and the track bed. In recent years, a near-track sound barrier is used on the ground of the section of the urban rail transit ground line in some cities in China. The near-track sound barrier is installed near the track, has small volume, light weight, low height and good sound absorption and insulation effect, but the problems of position conflict between the single near-track sound barrier and the interval cable support, evacuation platform and other rail side equipment, operation and maintenance are not solved. In the section of the traditional urban rail transit ground line, the near-track sound barrier, the evacuation platform, the power supply and the signal cable support are independently installed, which not only occupies a large area and is complicated to install, but also often causes failure due to the complex installation of the rail side equipment and pipelines, poor coordination, high operation and maintenance cost, great influence on the bridge load, and urgent need for integration and optimization.
