Description

[0001] Close Railway Soundproofing Apparatus [0002]

More particularly, the present invention relates to a rail-proximate low-noise-isolating wall having a sound-insulating unit including a plurality of sound-isolating members that are foldably connected to each other, will be.

Generally, in order to reduce the noise generated from the railway, a soundproof wall with a height of 2 to 3 m or more is often installed on the line side. At this time, the best way to reduce pathway noise is to install soundproofing facilities as close as possible to the source of noise generation.

The main noise generated when driving an electric locomotive (including a train) except a diesel train is the electric noise generated between the rail and the train. Therefore, when a low-sound-absorbing wall is installed close to the rail at a height that does not interfere with the operation of the train, it has a greater noise reduction effect than a general sound-absorbing wall installed on the existing line.

Such a rail-adjacent low-floor soundproofing device is generally formed in a concrete form and is arranged adjacent to the periphery of the rail for noise reduction.

However, in the case of the conventional rail close-up low-soundproofing device, there is a problem that interference occurs when the equipment is repaired such as a jiggling machine or a sleeper replacement because it is installed adjacent to the rail. Especially, it is called a ballast cleaner which is a repairing equipment for jiggalli. It has a relatively wide width than the width of a general train, and also has a wide width. Therefore, when a near-floor soundproofing device is installed, interference is inevitably generated.

That is, the operator can not secure a sufficient working space by the installed near-floor soundproofing apparatus installed. Therefore, it is necessary to dismantle the soundproofing apparatus for smooth maintenance work.

However, in the case of transporting the whole of the near-field low-frequency soundproofing device, the entire soundproofing device of the concrete type must be lifted, thereby increasing the air length and increasing the cost for the maintenance work.

Therefore, a method for solving such a problem is required.
