Construction scheme of high speed rail sound barrier

The high-speed rail sound barrier is a barrier built to reduce the impact of noise generated by high-speed trains on the surrounding environment and residents. The following is the general high-speed rail sound barrier construction scheme:

1. Scheme design: Determine the design scheme of the sound barrier according to the specific situation, including the length of the high-speed railway line, the surrounding environment, noise source and other factors. The design of the scheme should consider the noise characteristics of the high-speed train and the law of sound wave propagation, and choose the appropriate material and structural form.

2. Geological investigation: Geological investigation is required before construction to understand the underground situation and ensure the stability and shock resistance of the foundation in order to provide good basic conditions for the construction of the sound barrier.

3. Material selection: Select the appropriate material according to the design scheme of the sound barrier. Common materials include precast concrete, fiberglass, aluminum alloy, etc., which have good sound insulation and corrosion resistance.

4. Construction preparation: It is necessary to carry out construction preparation before construction, including cleaning the construction area, setting up the construction site, preparing construction equipment and materials.

5. Infrastructure construction: According to the design scheme, the foundation construction of the sound barrier is carried out on the foundation, including the excavation and filling of the foundation and the pouring of the foundation concrete.

6. Structure construction: According to the design scheme, the structural form of the sound barrier is generally constructed in the form of prefabricated components, which are assembled and installed.

7. Sound insulation treatment: sound insulation treatment is carried out inside the sound barrier, such as adding sound insulation materials, shock absorption measures, etc., to improve the sound insulation effect of the sound barrier.

8. Surface treatment: The outer surface of the sound barrier is treated, such as spraying, painting anti-corrosion paint, etc., to increase the weather resistance and appearance of the sound barrier.

9. Environmental restoration: After the construction, restore the environment of the construction site, clean up the construction waste, and carry out environmental protection and greening restoration.

The above is a general high-speed rail sound barrier construction scheme, the specific construction scheme should be adjusted and refined according to the specific situation. During the construction process, relevant safety and environmental protection standards should be observed to ensure construction quality and safety.
