常见的高速公路声屏障样式
常见的高速公路声屏障,中部采用(百叶窗式)吸隔声板,上部微弧形(百叶窗式)吸隔声板。吸隔声板面板和背板均采用镀锌钢板,吸声填料采用离心玻璃棉,吸隔声板表面均进行喷涂防腐处理。声屏障立柱采用H型钢立柱,声屏障立柱与基础用预埋地脚螺栓进行连接,吸隔声板与立柱的连接采用弹簧片进行弹性连接;隔声板、吸声板(隔声屏)固定在两边的立柱上。
The common highway sound barrier adopts (shutter type) sound absorption and insulation board in the middle and micro arc type (shutter type) sound absorption and insulation board in the upper part. Galvanized steel plate is used for the panel and back plate of the sound absorption and insulation board, centrifugal glass wool is used as the sound absorption filler, and the surface of the sound absorption and insulation board is sprayed with anti-corrosion treatment. H-shaped steel column is used for the column of sound barrier, the column and foundation of sound barrier are connected by embedded anchor bolts, and the connection between sound absorption and insulation board and column is elastically connected by spring pieces; sound insulation board and sound absorption board (sound insulation screen) are fixed on the columns on both sides.
