A sound insulation wall used in urban planning expressways

Abstract

The invention discloses a sound insulation wall used in urban planning highways. The invention has a reliable structure and effectively improves its wind resistance. At the same time, the sound-absorbing lining board and the sound-absorbing board can well absorb noise and prevent noise from echoing, At the same time, the cavity surrounded by the sound-absorbing liner and the outer support plate is also equipped with a dryness-absorbing mechanism that absorbs sound wave energy. The dryness-absorbing mechanism can realize the energy absorption of noise and sound waves, fundamentally The removal of noise is realized above. The multiple vertically suspended energy-absorbing spring wires of the present invention are located in the cavity in a suspended manner, have a simple structure, and are reliable in absorbing sound wave energy, and are arranged in the cavity , will not be damaged, will not be affected by the external environment, effectively improve the sound absorption capacity, and at the same time, the invention has a simple manufacturing method and is convenient for batch manufacturing, production and construction.

Description

technical field [0001] The invention relates to a sound insulation wall, in particular to a sound insulation wall used in urban planning highways. Background technique [0002] With the continuous development of expressways, expressways have spread all over the place, and for expressways passing through urban areas or residential areas, the noise of high-speed vehicles on the expressway has a greater impact on residents, and this noise is difficult to effectively control. To avoid, in this regard, the problem of noise reduction is realized by setting sound insulation panels in some highway parts. However, the current sound insulation boards are generally realized by double-layer glass or double-layer plastic boards. In fact, it is difficult to effectively remove or absorb noise in this way, and in fact, when this board is used, it is often easy to This causes problems such as resonance and echo in the noise. This noise still has a great impact on the surrounding environment...

Problems solved by technology

However, the current sound insulation boards are generally realized by double-layer glass or double-layer plastic boards. In fact, it is difficult to effectively remove or absorb noise in this way, and in fact, when this board is used, it is often easy to Causes problems such as resonance and echo in the noise. This noise still has a great impact on the surrounding environment. Moreover, the wind resistance and service life of this kind of board are relatively poor, which affects the use ability.
