SOUND INSULATION CONSTRUCTION METHOD OF TUNNEL SOUNDPROOF DOOR AND SOUND INSULATION STRUCTURE OF TUNNEL SOUNDPROOF DOOR
To provide sound insulation structure for a soundproof door 20 of a tunnel 10 in which sound insulation performance of the soundproof door 20 can be improved relative to a wide low frequency band.SOLUTION: Sound insulation structure for a soundproof door 20 of a tunnel 10 includes a first fixing plate 60 extending upward from a top edge 32 of a vehicular door 30 provided to the soundproof door 20, and first bolts 62 for fixing the first fixing plate 60 to the soundproof door 20. Sound insulation structure for the soundproof door 20 of the tunnel 10 also includes a second fixing plate 70 extending downward from a bottom edge 34 of the vehicular door 30, and second bolts 72 for fixing the second fixing plate 70 to base concrete 40.SELECTED DRAWING: Figure 1
【課題】本発明は、幅広い低周波数の帯域に対して防音扉２０の遮音性能を向上させることができるトンネル１０の防音扉２０の遮音構造を提供する。【解決手段】トンネル１０の防音扉２０の遮音構造は、防音扉２０に設けられる車両用扉３０の上端３２から上方へ延びる第１固定板６０と、第１固定板６０を防音扉２０に固定する第１ボルト６２と、を含む。また、トンネル１０の防音扉２０の遮音構造は、車両用扉３０の下端３４から下方へ延びる第２固定板７０と、第２固定板７０をベースコンクリート４０に固定する第２ボルト７２と、を含む。【選択図】図１
