Abstract

The invention discloses a rail transit wind-guiding type sound barrier and an installation method thereof, comprising a plurality of support plates forming the sound barrier, a side connection mechanism connecting two adjacent support plates, a top cover plate covering the support plates, and a The punching noise reduction plate in the support plate, the top surface of the support plate is centered with a cavity downward, and a side opening connecting the cavity is opened at the top of the side of the support plate facing the station rail, the top surface of the support plate There are side slots on both sides, the punched noise reduction plate is vertically inserted into the cavity of the support plate, and moves laterally in the cavity through the compression sliding mechanism, and two adjacent support plates pass through the side slots It is fixedly connected with the side connecting mechanism. The invention can use the gaps on both sides and the sealing rubber plates filled in the gaps to make the high-speed rail impact the support plates by the wind pressure when passing through the sound barrier, forming a buffer between adjacent support plates, thereby reducing the impact force , to improve the stability of the support plate during installation.

Description

technical field [0001] The invention relates to the technical field of vibration reduction and noise reduction in railway track engineering, in particular to a rail traffic wind-guiding type sound barrier and an installation method. Background technique [0002] In recent decades, rail transit, especially high-speed rail construction, has achieved rapid development in China and other countries in the world. Attracting more and more people to choose rail transit as a way of travel, but due to the high speed of the train when it is running, the current sound barrier has the following problems: [0003] First of all, since the track is not a straight line, in order to make the distance between the sound barrier and the track the same when installing the sound barrier, the sound barrier is often not straight. However, when installing a curved sound barrier, it is necessary to install The support element has a corresponding arc shape, the installation is more laborious, and the ...
