Description

Technical Field

[0001] The present invention relates to the technical field of sound barriers, and in particular to a double sound insulation type high-speed rail sound barrier. Background Art

[0002] High-speed rail sound barriers are facilities used to reduce the impact of noise generated by high-speed trains on the surrounding environment and residents. Its main function is to reduce noise transmission through isolation and sound absorption technology, thereby protecting the quality of life of residents along the line.

[0003] As an important tool for high-speed rail noise control, high-speed rail sound barriers not only effectively solve the noise pollution problem of residents along the line, but also improve the overall image of the railway and the travel experience of passengers.

[0004] At present, the existing technology still has the following areas for improvement: the existing high-speed rail sound barriers often adopt a single-layer structure, which leads to limited effect in isolating the various noises generated by the operation of high-speed rail. Single-layer sound insulation materials often cannot fully cover and effectively absorb noises of different frequencies, especially in the complex noise environment generated by high-speed rail. Its sound insulation performance is even more insufficient. In addition, when such sound barriers are exposed to natural environmental factors such as long-term wind, sun, rain erosion, etc., the sound insulation materials are prone to aging, which further reduces the sound insulation effect, so that residents along the line will still be disturbed by the high-speed rail noise, affecting their quality of life.
