CURVED NOISE BARRIER

摘要

The present invention relates to a curved noise barrier coupled to the uppermost part of a noise barrier provided in the vertical direction. Conventional noise barriers have a structural problem in that soundproof panels inserted into a column and a slant column have rear parts which become separated from each other such that a slant space is inevitably formed. Most seriously, even though the front parts are in contact with other soundproof panels and low frequencies having small wavelengths can be blocked among the wavelengths of noise sources, high frequencies having large wavelengths easily pass through the front parts at a contact portion of a small area and advance to the outside of the noise barrier through the slant space. The present invention provides a curved noise barrier, wherein a curved soundproof block having a smoothly curved surface is provided at the uppermost end of the noise barrier which is vertically provided and prevents the noise sources due to the noise of roads, wind pressure or the like from being transmitted to residential zones. At the time of laminating, no gap is generated such that the noise sources can be blocked and simultaneously induced to the roads for the compensation of the noise even without using any additional finishing materials. Further, a sound shield plate provided to the front portion of the barrier wall can be attached thereto or detached therefrom such that the maintenance, repair and exchange of the noise barrier are enabled. In addition, an illumination device is provided to the inside of the curved soundproof block positioned at the uppermost end of the noise barrier so as to substitute a streetlight.
