Temperature change sound insulation barrier for roads

Abstract

The invention belonging to the field of sound insulation barriers discloses a temperature change sound insulation barrier for a road. The temperature change sound insulation barrier for roads comprises a pair of concrete guardrails, a plurality of self-adjusting sound insulation barriers are connected between the pair of concrete guardrails; guide pipes are connected among the plurality of self-adjusting sound insulation barriers; a pair of inner protective layers is connected between the inner walls of the pair of concrete guardrails; each inner protective layer comprises a pair of door fences matched with the concrete guardrails; an inner protective layer is connected between the pair of door fences; the two ends of the guide pipes are fixedly connected with the two inner protective layers respectively; outer protection plates are laid on the self-adjusting sound insulation barrier; a double-layer protection plate matched with the self-adjusting sound insulation barrier is connectedbetween every two adjacent outer protection plates. The light transmittance of the self-adjusting sound insulation barrier can be changed according to the external temperature change, direct sunlightis reduced to change the temperature in the sound insulation barrier, and the temperature range of the sound insulation barrier can be reduced according to needs to control the light transmittance change amplitude of the sound insulation barrier.

Description

technical field [0001] The invention relates to the field of sound insulation barriers, in particular to a temperature-varying sound insulation barrier for roads. Background technique [0002] With the development of my country's economy, the number of domestic automobiles continues to rise, and the construction of urban roads, expressways, intercity light rails, and high-speed rails has also entered a period of rapid development. However, while providing convenient transportation, the traffic noise generated by it also has a negative impact on the health and life of surrounding residents. Therefore, effective prevention and control of road noise pollution is not only an important environmental issue, but also a social issue that has attracted public attention. Therefore, it has become a trend to continue to develop anti-dry, sound-proof and environmentally friendly products, and to isolate and eliminate noise from the source and transmission of noise. [0003] Most of the...

Problems solved by technology

[0004] At present, fully enclosed sound barriers have begun to appear. The existing fully enclosed sound barriers are usually added with top sound insulation screens on the top of the upright sound barriers on both sides, which reduces the transmission of noise, but the light transmittance is poor, and the personnel in the barrier cannot be easily Good observation of the environment outside the barrier, so that the personnel inside the barrier cannot judge the surrounding road conditions outside the barrier, which may easily cause traffic accidents
