Key Technologies for the Construction of Metal Structure Sound Barriers in Composite Roadbeds of Highways
In order to reduce noise on both sides of the highway and improve the quality of life of the surrounding residents.The design and construction of sound barriers have always been a key research direction in the field of architecture.In the past,China mainly used fiberglass sound barriers to isolate noise on highways.However,due to the insufficient acoustic,mechanical,and aging resistance of this sound barrier,it has become difficult to meet the urgent needs of the times.In this era,metal structure sound barriers have attracted widespread attention due to their good noise reduction effect,durability,and easy installation.In view of this,this article will rely on the Sichuan Tianfu New Area to Qionglai Expressway Greening Project to conduct research on the installation of composite sound barriers.That is,an open white leaf hole aluminum alloy sound-absorbing plate is inserted between the noise source and the sound receiving point,so that the sound wave is significantly attenuated due to the influence of obstacles during propagation.The aim is to reduce the noise impact of nearby residents in a certain area,hoping to provide some reference.
