The present invention relates to an apparatus installed inside a road tunnel, and in particular, to absorb noise generated as a vehicle travels inside a road tunnel and to remove impurities such as dust and dirt contained in the air in the tunnel. Relates to a device.

In general, when passing through the interior of a tunnel by a vehicle, the driver's attention is required due to the narrowing of the field of view and glare by the lighting.

In other words, the noise generated from the vehicle driving inside the tunnel is reflected on the inner wall of the tunnel, which interferes with the driver's hearing, causing problems in driving, and also causes the driver's anxiety due to tinnitus. There is a problem that a large accident can occur.

Therefore, in order to improve the above problems, there is a Republic of Korea Utility Model Registration No. 20-0279267, which is schematically shown in FIG. Referring to the drawings, a vehicle noise absorbing device installed in a conventional tunnel will be described below.

Conventional vehicle noise absorbing device, a plurality of H-shaped steel (1) which is horizontally fixed at a predetermined interval on the upper and lower portions in the tunnel inner wall, and the polyester is filled inside and finished with a polyethylene plate on both sides to the outside Sound absorbing panel (2) which is installed in contact with the outside of the H-beam, longitudinal reinforcing bar (3) assembled and fixed vertically from the outside of the H-beam to support the side of the sound-absorbing panel (2), and the H-beam (1) Located in correspondence with the sound absorbing panel 2 on the outside of the sound absorbing panel 2 and located in correspondence with the H-shaped steel 1 and out of the sound absorbing panel 2 with the sound absorbing panel 2 in the H-shaped steel ( It is composed of a fixed band (4) that is assembled and fixed to 1).

In the above-described configuration, the uppermost H-shaped steel 1 of the H-shaped steel 1 is configured to correspond to the inclined surface of the upper corner of the tunnel by having an inclined surface 5 extending from the top of the outer surface thereof inclined upward and upward, The lowermost H-shaped steel is formed so that the accommodating portion constituting the recess (6) is formed so that the sound absorbing panel 2 can be accommodated and supported, the uppermost sound absorbing panel (2) of the sound absorbing panel (2) It is configured to correspond to the inclined surface.

In the conventional vehicle noise absorbing device, the noise absorbed by the sound absorbing panel is generally reflected, so that the noise is absorbed back to the outside of the sound absorbing panel to generate residual noise. Therefore, a method for more efficiently absorbing noise needs to be sought. .

On the other hand, since there are many vehicles passing through the tunnel, a lot of smoke is contained in the air inside the tunnel.

In addition, due to the nature of the tunnel, soot does not easily fall out, especially in the case of a long tunnel (long tunnel), a very serious air pollution occurs.

Due to the problems as described above, in recent years, tunnels are generally installed in the center of the tunnel to install a natural ventilation using a communication effect or to install a large ventilator.

And when the amount of soot is large, an electric precipator may be installed.

However, the installation of such a ventilator is not to remove the smoke completely, but to minimize it.

Therefore, when the driver passes in a state exposed to the air in the tunnel for a long time, the problem is that the health of the driver is deteriorated due to excessive stress on the bronchus of the driver.

The present invention was devised to solve the conventional problems as described above, to minimize the hearing impairment of the driver by absorbing the noise of the vehicle generated inside the road tunnel, and also removes the fine dust contained in the air inside the tunnel Accordingly, an object of the present invention is to provide a sound absorbing and air purifying device for a tunnel that can be comfortably operated by a driver by opening a car window.

In order to achieve the above object, it is installed on the inner wall of the tunnel, while a fixed end is formed at the lower end, which is installed in the recess groove of the side wall bottom concrete, is fixed by bolts, and the longitudinal support and the horizontal support are integrally formed with the FRP material.
