Sound barrier applied to existing railway line and mounting method thereof

Abstract

The invention relates to the technical field of building materials, and provides a sound barrier applied to an existing railway line and a mounting method thereof. The sound barrier comprises sound barrier stand columns, sound barrier back plates, sound absorbing plates, a ground foundation and transparent plates. The ground foundation is provided with cup opening parts, and the sound barrier stand columns are inserted into the cup opening parts. The sound barrier stand columns are provided with strip-shaped mounting grooves, each sound barrier back plate comprises a back plate body, and the sound absorbing plates are embedded into the back plate bodies; the sound barrier back plates are embedded into the mounting grooves of the corresponding two adjacent sound barrier stand columns; and each transparent plate is arranged between every two adjacent back plate bodies and connected with the corresponding mounting grooves and the corresponding upper and lower back plate bodies. The soundbarrier has the advantages of being firm in connection, light, high in intensity, long in service life, good in sound isolation effect and the like. The mounting method comprises the steps of sequentially mounting the ground foundation, the sound barrier stand columns, the back plate bodies provided with the sound absorbing plates, the transparent plates and other back plate bodies provided with the sound absorbing plates. The mounting method is scientific and reasonable in design, easy and convenient to operate and capable of firmly mounting the sound barrier.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a sound barrier applied to existing railway lines and an installation method thereof. Background technique [0002] With the rapid development of my country's transportation industry, the problem of traffic noise pollution is becoming more and more serious. According to the estimates of the World Health Organization, the annual losses caused by work-related accidents, non-working and low efficiency in the United States due to the impact of noise are nearly $4 billion. With the acceleration of high-speed rail construction in my country, noise disturbance incidents continue to occur. Reducing the disturbance of noise to residents on both sides of the railway has become an important task in the construction of high-speed railways in my country. Although China's high-speed railway occupies less land, consumes less energy, and emits less air pollutants, the noi...
