Positive effect increase, big arc sound barrier can also be buffered by being hit strongly caused by contingency, reduce damage；Sound barrier
Top undulated design, mainly for the sound wave of the diffraction at the top of sound barrier, diffraction sound wave passes through multi-angle remission in wave
Friction is produced with refraction and wave edge, energy is consumed, has been efficiently reduced when passing to recipient；Pass through aluminium alloy sound-absorbing
The sound wave that the combination of plate, polyester fiber acoustical cotton and aluminium alloy sound panel makes to transmit at sound source jointly is greatly disappeared
Consumption, so as to effectively reduce the transmitted acoustic pulse of recipient's reception, reach effective noise reduction；Transparency window, perspectivity is good, can be with ring around
Border is mutually coordinated, and the effect of effectively mitigating highway driving person's vision sense of depression, and have sound-absorbing and sound insulation concurrently, will not reduce sound-screen
Hinder soundproof effect；The both sides rear wall of bent frame is symmetrically fixedly connected with support, and the arc-shaped connecting rod in support can be dragged firmly
Firmly bent frame, whole sound barrier is steadily contacted with contact surface, ensure the stability of sound barrier.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of highway sound barrier, including arc
Framework 1, the middle part front side of the bent frame are connected with aluminium alloy abatvoix 2, are connected with rear side of the middle part of the bent frame
Aluminium alloy sound panel 4, polyester fiber acoustical cotton 3, big arc are accompanied between the aluminium alloy abatvoix and the aluminium alloy sound panel
Ideophone barrier adds the reflective surface area of sound wave, reduces diffraction approach of the sound wave at the top of sound barrier, and noise reduction substantially increases,
Big arc sound barrier can also be buffered by being hit strongly caused by contingency, reduced damage, by aluminium alloy abatvoix, gathered
The sound wave that the combination of ester fiber acoustical cotton and aluminium alloy sound panel makes to transmit at sound source jointly is greatly consumed, from
