Outer coverage sound barrier
The invention discloses an outer coverage sound barrier. The sound barrier comprises a parallel main frame and a plurality of purlines which are arranged on the outside of the main frame and are vertical to the main frame. A sound absorption barrier plate is arranged on the purlines, supports distributed in an array are arranged on the outsides of the plurality of the purlines, first sound insulation plates forming sound absorption cavities with the sound absorption barrier plate are arranged on the supports, second sound insulation plates are arranged on the supports and are fixed on keels, and the second sound insulation plates and the first sound insulation plates form sound insulation cavities. By means of the sound barrier, the sound barrier structure is arranged on the outside of the main frame without occupying the frame internal space, and accordingly, the problem that precast units in totally sealed or half sealed sound barriers cannot be inserted in H-shaped steel wing margin plates of insertion plate type barriers is solved; meanwhile, the outer coverage sound barrier is arranged continuously and can be produced in field according to particular conditions, the front of the sound barrier is a sound absorption face, the problem of the reduction of the sound absorption face due to shielding of the main frame is absent, and the acoustical absorption coefficient is high.
