What are the characteristics of a high-speed sound barrier?


The characteristics of a high-speed sound barrier are high sound insulation, high sound absorption coefficient, vibration isolation, fire prevention, water resistance, dust prevention, corrosion resistance, beautiful and durable, and good sealing performance. The construction of high-speed sound barriers should pay attention to the underground part of the foundation and the ground beam. We will introduce the relevant content in detail below.


The function of a high-speed sound barrier is to block the propagation of direct sound, isolate the propagation of sound, and allow sufficient attenuation of diffracted sound. When sound waves strike the wall of a high-speed sound barrier, diffraction occurs at the edge of the barrier, forming a "sound shadow zone" behind the barrier. The expected noise reduction effect of the highway sound barrier is within the "sound shadow zone". The wavelength of sound waves is much longer than that of light waves, so the boundary of this "sound shadow zone" is not obvious. Sound waves emitted from the source can directly reach this range by passing over the edge of the barrier, which is called the "bright zone". There is also a small "transition zone" between the light and sound shadows. The noise level in the "sound shadow zone" is lower than the noise level without a sound barrier, which is the basic principle of noise reduction of high-speed sound barriers.


As a form of construction, high-speed sound barriers will inevitably have an impact on the surrounding environment. A well-designed high-speed sound barrier, in addition to having a significant noise reduction effect, should also be able to blend with the surrounding environment. The design principles are as follows: environmental integration will not destroy the original landscape, but will also add new highlights to the environment; three-dimensional greening: using sound barriers for three-dimensional greening; open vision: after setting up sound barriers on both sides of the road, the vision inside the road will become narrower, especially in some scenic areas, which will affect the appreciation of nature by riders. To solve this problem, transparent panels can be used as sound insulation materials.


Installation method of high-speed sound barrier: After the high-speed sound barrier construction personnel Enter the site, they should be trained and educated on the relevant regulations and rules of safety production before construction can begin. Assign specialized safety personnel to conduct safety inspections at any time during the construction process. Timely identify and correct any unsafe conditions or safety hazards for construction personnel, establish safety production reward standards, reward individuals or groups who have outstanding performance in safety production, and severely criticize or punish those who do not attach importance to safety production, have paralyzed thinking, and violate safety production rules and regulations during construction. Reward and punishment guidelines can urge construction personnel to abide by the guidelines and prevent unnecessary losses. By doing the above three points, the quality of the highway sound barrier project and the safety of the construction personnel can be guaranteed. So-called top-level safety means not being careless.
