Voiceproof wall for highways in urban planning

Abstract

The invention discloses a voice insulation wall for a highway for urban planning. The structure is reliable, the wind resistance is effectively improved; meanwhile, the voice absorption lining plate and the voice absorption plate can well absorb noise; the problems of echo, resonance and the like of noise are prevented; meanwhile, a noise removing and energy absorbing mechanism for absorbing voicewave energy is further arranged in a cavity defined between the voice absorbing lining plate and the outer supporting plate. The noise removing and energy absorbing mechanism can realize energy absorption of noise voice waves; the noise removal is fundamentally realized; the invention discloses a plurality of vertically suspended energy absorption spring wires. The energy absorption spring wire is located in the cavity in a hanging mode, the structure is simple, voice wave energy absorption is reliable, the energy absorption spring wire is arranged in the cavity, damage is avoided, the energyabsorption spring wire is not affected by the external environment, the voice absorption capacity is effectively improved. Meanwhile, the manufacturing mode is simple, and batch manufacturing, production and construction are facilitated.

Description

Technical field [0001] The invention relates to a soundproof wall, in particular to a soundproof wall used for expressways in urban planning. Background technique [0002] With the continuous development of expressways, expressways have been spread all over the country. For expressways that pass through urban or residential areas, the noise of high-speed cars on the expressway has a greater impact on residents, and this kind of noise is difficult to carry out effectively. To avoid this, noise reduction problems can be achieved by installing sound insulation boards in some road parts. However, the current sound insulation panels are generally realized by double-layer glass or double-layer plastic panels. This method is actually difficult to effectively remove noise or absorb sound. In fact, when such panels are used, it is often easy This makes the noise appear resonance, echo and other problems. This kind of noise still has a great impact on the surrounding environment. Moreover...

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.
