Abstract

The invention relates to a railway isolation noise reduction board. The railway isolation noise reduction board is provided with an arc-shaped board with an S-shaped or C-shaped vertical face. The railway isolation noise reduction board is simple in structure, the transverse strength in the railway running direction is high, manufacturing is extremely easy, and the isolation height is increased.

Description

technical field [0001] The invention belongs to the technical field of railway construction. Background technique [0002] Nowadays, the passenger and freight traffic of the railway is large and the speed is fast. Passing through cities and towns and passing through densely populated rural areas, both isolation and noise reduction are required. However, no matter what material is used for the board surface, no matter what kind of folds are made, the boards in use are all flat. Not only the strength of the board is low, but also more materials are used. Contents of the invention [0003] In view of the above defects, the present invention proposes a railway isolation and noise reduction board. [0004] The present invention mainly consists of an arc-shaped plate and a frame. The arc-shaped plate in the present invention is longitudinally S-shaped or C-shaped, and the frame column is S-shaped or C-shaped to match the arc-shaped plate. [0005] The frame beams are straight....
