Abstract

The invention provides a circular totally-closed sound barrier for a high-speed rail, which comprises a sound barrier foundation, a frame constructed on the sound barrier foundation to form opposite side closing and sound barrier assemblies formed in the frame, and is characterized in that the frame is a steel structure frame with an arc-shaped cross section, and two arc-shaped ends of the steel structure frame are arranged on the sound barrier foundation; the sound barrier assemblies are symmetrically located on the two sides of the circular totally-closed sound barrier for the high-speed rail, and the sound barrier assemblies located on the two sides are each sequentially provided with a lower arc-shaped metal sound barrier plate set, an arc-shaped transparent sound barrier plate set andan upper arc-shaped metal sound barrier plate set from bottom to top; and the arc-shaped metal sound barrier plate set comprises one or more arc-shaped metal sound barrier plates, the arc-shaped transparent sound barrier plate set comprises one or more arc-shaped transparent sound barrier plates, and every two adjacent barrier plates are connected through a connecting piece.

Description

technical field [0001] The invention relates to the technical field of sound barriers, in particular to a fully enclosed sound barrier for high-speed rail. Background technique [0002] With the rapid development of my country's economy and society and the continuous improvement of people's living standards, the means of transportation and travel methods are developing rapidly. As a mode of transportation that can quickly transport passengers and goods, high-speed rail is increasingly playing an important role. High-speed rail usually passes through rural villages, urban suburbs and urban areas. During the operation of high-speed rail, major noise sources such as wheel-rail noise and aerodynamic noise will be generated, which will bring great impact to the life, work and study of residents on both sides of the train. influences. [0003] At present, the main noise reduction measures for high-speed rail are vertical sound barriers. The mechanical properties of high-speed rai...
