| description | The sound absorption and insulation wall structure comprises an outer steel plate and a plurality of outer keels fixedly connected to the inner side of the outer steel plate at intervals. The inner steel plates and the outer steel plates are arranged at intervals, and a plurality of inner keels are fixedly arranged on the outer sides of the inner steel plates at intervals; the inner keels and the outer keels are arranged at intervals inside and outside, and the inner keels and the outer keels are arranged in an up-down staggered mode. A sound absorption material and a perforated plate are fixedly arranged on the inner side of the inner steel plate in sequence; the edge of the inner steel plate and the edge of the outer steel plate are fixedly connected through a steel structure. The sound absorption and insulation wall body structure and the fabricated wall body integrally have high sound absorption and insulation performance, correspond to a low-frequency protruding sound source in a plant, and are good in s |
