[0002] Highway sound insulation walls are structures designed to reduce the impact of traffic noise on surrounding residents and the environment. They are usually built along the side of the highway and can effectively absorb, reflect or reduce the passing noise level.

[0003] When the existing highway sound insulation walls are in use, generally, sound insulation boards or sound insulation foams are used as fillers to fill the highway walls. The filling method not only causes irreversible damage to the internal sound insulation structure when the internal sound insulation structure is collided by the outside or foreign objects enter, but also affects the convenience of replacing the sound insulation structure. Moreover, the sound insulation and noise reduction range and effect of a single sound insulation board and sound insulation foam are very limited, and it is often difficult to effectively reduce the impact of the noise generated by highway vehicles on the surroundings.

[0004] Therefore, aiming at the problems that the single sound insulation structure of the above-mentioned highway sound insulation wall usually has difficulty in efficiently sound insulation and noise reduction treatment for the vehicle noise on the highway, and the filling sound insulation structure in the wall is also difficult to be quickly replaced as needed, a combined highway sound insulation wall which is convenient to replace is developed. By installing a double protection structure, a double-layer sound insulation and absorption structure, a high-place noise reduction structure, a rotating and tilting structure and a limit assembly structure on the highway sound insulation wall, the sound insulation and noise reduction effect and range of the device for highway vehicle noise can be greatly improved, the assembly convenience of the device and the service life of its sound insulation structure can be improved, and the cost of replacing and maintaining its sound insulation structure can also be reduced.
