Near-rail noise reducing device at T-beam and mounting method of noise reducing device

Abstract

The invention discloses a near-rail noise reducing device at a T-beam and a mounting method of the noise reducing device. The noise reducing device comprises a ballast blocking wall and a sound barrier, wherein the ballast blocking wall is mounted between the rails and a sidewalk plate, and the sound barrier is mounted above the ballast blocking wall or on one side, which faces a subgrade, of the ballast blocking wall. Through the use of the near-rail noise reducing device at the T-beam and the mounting method of the noise reducing device, which are disclosed by the invention, potential safety hazards caused by that a conventional sound barrier at the T-beam is placed on a sidewalk bracket can be effectively eliminated, the design height of the sound barrier can be reduced, the cost of mounting the sound barrier can be reduced, and a good noise reducing effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of railway environmental protection, in particular to a T-beam near-rail noise reduction device and an installation method thereof. Background technique [0002] In the prior art, a large number of multi-piece T-beams are used in passenger-cargo railways, and the current T-beams of passenger-freight railways are in the form of sidewalks with angle steel brackets, and sound barriers are generally installed on the outside of angle steel brackets. . figure 1 It is a schematic diagram of a sound barrier in the prior art. Such as figure 1 As shown, the sound barriers 1 in the prior art basically adopt a plug-in installation method. Although the sound barrier 1 in the prior art can also reduce noise, since the sound barrier 1 is installed on the sidewalk support 2 of the bridge T-beam 3, and the sidewalk support bears limited loads, there will be certain potential safety hazards. Moreover, the sound barrier in...

Although the sound barrier 1 in the prior art can also reduce noise, since the sound barrier 1 is installed on the sidewalk support 2 of the bridge T-beam 3, and the sidewalk support bears limited loads, there will be certain potential safety hazards

Moreover, the sound barrier installed in this way has a large height limit, so it will also affect the noise reduction effect of the sound barrier; at the same time, the sound barrier installed in this way also has increased maintenance and repair workload and reduced sidewalk support structure Service life and other issues
