Case of closed sound barrier

Engineering Introduction:
In the urban area, it is necessary to pay special attention to the high-rise buildings on both sides of the urban traffic road, which will form the "Canyon" effect of the city. The research shows that the sound pressure level of the area is raised by the parallel "Canyon". At this time, it is very difficult to control the radiation from traffic noise to sensitive points by means of general sound barrier. The "fully enclosed sound barrier" is a typical way to solve these problems. In Japan and Canada, the "fully enclosed road sound barrier" means that a tunnel type sound insulation structure is installed on a road section. The vehicle and road are completely isolated in the sound barrier, and the noise generated by the vehicle and the reflection of the road are also reflected. Noise isolation in the sound barrier greatly improves the sound insulation effect of the sound barrier. It is suitable for road absorption, sound insulation and noise reduction of near sensitive impact sensitive targets, such as residential buildings close to roads.
Product features:
The full enclosed sound barrier consists of steel structures such as steel beams and other steel structures and the sound insulation material pervious to the panel. The top of the full enclosed sound barrier is designed to be arched, and the two sides are designed as erect. At the same time, the factors such as landscape effect, structural safety (anti wind load, snow load, etc.), and drainage of rainwater are also taken into account. After the complete closed sound barrier was completed, the impact of the sensitive point traffic noise on the residential buildings on both sides of the road was less than 70dB (A) in the day and lower than 55dB (A) at night, which reached the relevant national environmental standards.
