DOUBLE SOUNDPROOF WALL
PROBLEM TO BE SOLVED: To provide a double soundproof wall capable of effectively eliminating noises at blasting, especially low frequency noises, requiring no air duct opening/closing work by a worker.SOLUTION: A double soundproof wall 10 is applied to a tunnel construction. The double soundproof wall 10 is constituted of two sound proof walls 1 including a soundproof door 2, which are disposed being interposed by a space 4 to shut-off a tunnel in a cross section. Each of the sound proof walls 1 is formed with a through hole 3 for allowing an air duct 6 to penetrate therethrough. The air duct 6 which is deformable with a wind pressure is disposed penetrating the respective through holes 3 and extends in an extending direction of a tunnel T. In a space 4 between the two sound proof walls 1, sound absorption materials 5A and 5B are disposed in a direction perpendicular to the respective sound proof walls 1.SELECTED DRAWING: Figure 1
【課題】作業員による風管開閉作業を不要としながら、発破時の騒音、中でも低周波音を効果的に消音することのできる二重防音壁を提供する。【解決手段】トンネル工事で適用される二重防音壁１０であって、防音扉２を備えた二つの防音壁１が空間４を置いて、トンネル断面を遮断するように配設されて二重防音壁１０を構成し、それぞれの防音壁１には風管６が貫通する貫通孔３が設けてあり、風圧で変形自在な風管６がそれぞれの貫通孔３を貫通して配設されてトンネルＴの延伸方向に延びており、二つの防音壁１の空間４において、それぞれの防音壁１に対して直交する方向に吸音材５Ａ，５Ｂが配設されている。【選択図】図１
