Description

Noise barrier adjacent to railway

The present invention relates to a near sound barrier for a railway, and more particularly to a near-sound barrier for a railway which is made of a metal material soundproof wall which is installed close to a railroad, and which can be foldably connected to the rail side.

Generally, a soundproof wall is formed by installing posts (for example, H beams) at regular intervals on the sides of roads, roads or bridges, and assembling the soundproof panels by sliding the soundproof plates in the joining grooves of adjacent posts and posts. The sound absorbing material is filled so as to reflect and block the noise caused by the noise. This makes it possible to absorb and block fricatives and aerodynamic noise caused by friction between the wheels and the rail of the railway vehicle by the soundproof walls.

At this time, when the portion where the soundproof wall is installed is a bridge portion, the height of the soundproof wall is limited. That is, when the height of the soundproof wall is increased to increase the effect of blocking the noise caused by the railway vehicle, the weight of the soundproof wall is increased, causing a structural safety problem in the bridge due to the wind load.

On the other hand, in case of installing a lightweight reinforced concrete soundproof wall on a bridge, the weight of the soundproof wall may cause a structural problem to the bridge. In addition, it is not easy for a worker to pass a soundproof wall with a height of about 1.5m in case of emergency due to a fire or bridge, railroad track, and maintenance. As a result, in case of an emergency, when passing through a sound barrier, it is possible to suffer a loss of valuable lives and logistics costs.

An embodiment of the present invention relates to a near-sound barrier for a railway that can reduce the structural safety problem of a bridge to a wind load by reducing the weight of a metallic soundproof wall installed close to a railway vehicle.

Hereinafter, the use of the near-sound barrier for railway according to the first embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2 (a), (b) and (c), it is possible to freely select the basic connection portion in which the near sound barrier wall is installed, according to the surrounding conditions of the bridge top plate. The fixtures 13 and 14 to which the railway ends and the middle bulk acoustic barriers are fixed are directly fixed on the concrete slab 11 on the bridge top plate or directly on the slabs 11, . At this time, the base plate 26 is mounted on the slab 11 or the string base 25, and the fixtures 13 and 14 are mounted on the vibration proof rubber pad 27 mounted on the base plate 26 .

2 (d), an iron plate 53 for covering the sound absorbing material 52 is mounted on the slab 11, and the fixing member 13 or 14 may be fixed on the iron plate 53 Called dry method).

The construction for fixing the fasteners 13 and 14 to the slab 11 to be poured by the concrete and the string base 25, the slab 11 or the string base 25 to be concrete laid on the slab 11 is described in detail in the description of the present invention And therefore detailed description of the configuration thereof will be omitted.

The railway end and the middle squad soundproofing walls (a, b) are respectively fixed to the above-described railway end and the middle squad fasteners (13, 14). That is, the soundproof wall (a) for railway is fixed to the fixture 13 so that the noise trap 24 thereof is directed to the side of the railway rail 12 from the rail of the upper plate, and the soundproof wall b for the middle partition is fixed to the noise trap 24 Is fixed to the fixing tool (14) so as to face the rail (12) side at an intermediate portion of the upper plate.

As described above, railroad ends consisting of upper and lower soundproof walls 17 and 19 are installed on the fixing fixtures 13 and 14 fixed to the slab 11 in the longitudinal direction of the railway rail 12, and soundproof walls for middle squads are installed. Done. That is, a separate pillar for installing the soundproof wall is unnecessary, and the rail ends and the middle component soundproof walls (a, b) made of the same cross section and structure are repeatedly installed in the direction of the railroad rail 12. As a result, it is possible to improve the workability of installing and demolishing the soundproof wall and reducing the construction cost. In addition, since the total height of the soundproof walls formed by the upper and lower sound barrier walls 17 and 19 is low, it is possible to prevent the generation of complaints such as the infringement of the right of daylight in the low- A wide field of view can be secured.

As shown in Figs. 1 and 5 (a, b), the above-described railway end and the middle component soundproof walls (a, b), the lower frame (15) of the lower soundproof wall (17) in their fasteners (13, 14) It is respectively fixed and connected to the lower frame 15 by a hinge h so that the upper frame 18 of the upper soundproof wall 19 is folded toward the rail 12 side.

As described above, the railway end and the middle squad soundproofing walls a and b are folded to the railway rails 12 with respect to their lower soundproof walls 17, so that in case of emergency or bridge due to a fire, etc. When checking the back, it is possible to pass over the sound barrier without bypassing the sound barrier (for example, when the upper sound barrier 19 is folded, the upper frame 18 maintains an angle of about 50 ° with respect to the ground).

As shown in Figs. 1, 3 (ae) and 5 (a, b), the noise is directed toward the railway rails 12 on the upper sound insulation walls 19 of the above-described railroad end and middle component sound barriers a and b. Each trap 24 is mounted. As a result, the rail ends and the middle squad soundproofing walls a and b are installed to approach the railway rails 12, so that the rail friction noise and the aerodynamic noise generated when the railroad vehicle v runs, the upper and lower soundproofing walls 17, 19 Is absorbed and blocked by the sound absorbing material 16 and the noise trap 24 provided in the).

That is, as shown in FIG. 3A, the noise generated when the railway vehicle v travels passes through the sound absorbing hole 20 and the slit guide 21 formed in the perforated plate 22 forming the noise trap 24, (23). A part of the noise absorbed into the hollow portion 23 passes through the sound absorbing hole 31 formed in the front plate 28 of the upper frame 18 and is absorbed by the sound absorbing material 16 of the upper frame 18, The noise absorbed in the hollow portion 23 is lost due to diffraction, interference, refraction and sound absorption, as in the direction of the arrow in FIG. 3 (a)). At the same time, a part of the noise absorbed into the hollow portion 23 collides with the front plate 28 of the upper frame 18 and the perforated plate 22 as indicated by an arrow, and is lost due to loss of noise energy.

The noise generated during traveling of the railway vehicle v passes through the sound absorbing holes 31 formed in the front plate 28 of the lower frame 17 constituting the lower sound absorbing wall 17, 16).

Therefore, it is possible to fundamentally eliminate the noise generated when the railway vehicle (v) is driven by the noise barrier installed near the noise source (the friction sound due to the mutual friction between the railway vehicle (v) and the railway rail do. In addition, since the soundproof wall is formed of a metal material (for example, a galvanized steel sheet is used), the weight of the soundproof wall is relatively lightened as compared with the soundproof wall of the conventional concrete material. Therefore, it is possible to solve the structural weakness caused by the wind load caused by installing the sound barrier on the railway bridge.

6 to 8 (a) and 8 (b) and 11, the near-sound insulation wall for railway according to the second embodiment of the present invention is characterized in that,

(For example, a case in which a soundproof wall is installed on a bridge top plate is described as an example) in a near sound barrier wall installed close to a railway rail,
