NOISE REDUCTION DEVICE, COMPACTION PLATE, COMPACTION DEVICE AND NOISE REDUCTION METHOD
PROBLEM TO BE SOLVED: To provide a compaction device to reduce noise of compaction work.SOLUTION: A noise reduction device 400 comprises: a rectangular elastic plate 420; a rectangular metal plate 440, which is disposed on one face of the elastic plate 420 and has multiple open holes 442; a fixture 460, which fixes the elastic plate 420 and the metal plate 440 to undersurface of the compaction plate of a plate compactor that is cited as one example of a compaction device in a state where the elastic plate 420 is positioned on upper side. Multiple open holes are formed on the elastic plate 420 so as to continue to the open holes 442 of the metal plate 440. Multiple open holes may be displaced from the open holes 442 of the metal plate 440 if necessary.SELECTED DRAWING: Figure 3
【課題】締固め作業の騒音を低減する締固め装置を提供する。【解決手段】騒音低減装置４００は、矩形形状の弾性板４２０と、弾性板４２０の一面に配置される、複数の貫通孔４４２が形成された矩形形状の金属板４４０と、弾性板４２０及び金属板４４０を、弾性板４２０が上位に位置する状態で、締固め装置の一例として挙げられるプレートコンパクタの締固め板の下面に固定する固定具４６０と、を有する。また、弾性板４２０には、金属板４４０の貫通孔４４２と連続するように、複数の貫通孔を形成し、必要に応じて、金属板４４０の貫通孔４４２とずらして配置してもよい。【選択図】図３
