The invention discloses a constructional engineering fence. The constructional engineering fence comprises a first perforated panel and a second perforated panel, wherein a resonant cavity is formed between the first perforated panel and the second perforated panel, an air layer is arranged in the resonant cavity, a silencing cylinder is installed in the resonant cavity, first through holes are evenly formed in the first perforated panel, second through holes are evenly formed in the second perforated panel, the two ends of the silencing cylinder are connected with the first through holes andthe second through holes, an airflow channel is formed in the middle of the silencing cylinder and communicates with the first through holes and the second through holes, silencing holes are formed inthe outer wall of the periphery of the silencing cylinder, the silencing holes communicate with the airflow channel, and the silencing holes are smaller than the airflow channel in diameter. According to the constructional engineering fence, sound waves penetrate through the silencing holes to enter the resonant cavity for noise reduction.
本发明公开了一种建筑工程围挡，包括第一穿孔面板和第二穿孔面板，第一穿孔面板与第二穿孔面板之间形成共振腔，共振腔内为空气层，在共振腔内安装有消音筒，在第一穿孔面板上均匀布置有第一通孔，在第二穿孔面板上均匀布置有第二通孔，消音筒两端分别与第一通孔和第二通孔连接，消音筒中部设置有气流通道，气流通道连通第一通孔和第二通孔，在消音筒四周外壁上开设有消音孔，消音孔与气流通道相通，消音孔孔径小于气流通道孔径；声波穿过消音孔进入共振腔降噪。
