Scope of application of expressway sound barriers
The construction and operation of expressways have promoted regional economic development, but have also added noise pollution to sensitive areas along the way, such as residential areas, colleges, and schools. Expressway sound barriers are widely used in expressways due to their small space occupancy and significant noise reduction. However, most design schemes are unscientific, and the design scheme, model selection, and material structure selection of sound barriers are relatively free and active.
Based on the absorption of the achievements of discussions from countries around the world and the summarization of the foundation of current expressway environmental protection theories, this article, through extensive research and discussion, has conducted a detailed classification and summary of the methods, materials, structures, and locations of expressway sound barriers, and provided examples of sound barrier structures, drawing sound barrier framework diagrams to provide a practical database for sound barrier design in China; comprehensively summarizing the experiences of sound barrier model selection and design schemes from countries around the world, this article derives expert evaluation retrieval strategies, specifications, standards, and methods for sound barriers, and discusses and develops a selection and evaluation system for sound barriers, making the design of sound barriers more standardized and reasonable, and maximizing the technical efficiency of sound barrier customization.
Based on the sound wave frequency pressure formula and transmission theory, this article deduces the diffraction loss theory of expressway sound barriers, deduces the calculation formula for finite-length sound barriers, and realizes programmatic calculation. A comparison is made with standardized optimization algorithms. Although the two are similar, the formula conversion is more convenient. The rationality of the expressway sound barrier selection calculation method is verified through the actual test certificate of the sound barrier on one side of the Hexu Expressway dam base. Based on this article, an engineering project case is used to illustrate the practical significance of the design scheme of domestic expressway sound barriers.
What issues should be considered when purchasing expressways?
When customers choose sound barriers, they should first understand the sound insulation effect of the sound barrier. The number of decibels reduced is a concern for users. The sound insulation barrier of Riffa sound barrier reduces 18-25 decibels. Another factor is safety hazards. For example, if it is more than 7 meters or more than 10 meters tall, what about safety? In any work, we don't do anything we're not sure about; safety is the priority, and we will design effectively. Price is also a factor for customers. Affordable prices will be recognized by many customers. Our company is a direct manufacturer of sound barriers, and the Price will definitely not be high. Finally, the service life should be considered. The sound barrier posts are treated with hot-dip galvanizing, and their service life is 50 years or more. The sound insulation materials are sprayed with high-temperature paint, and their service life is more than 20 years.
