A soundproof wall, also known as a noise barrier, is installed to reduce the noise generated during the operation of high-speed vehicles and prevent surrounding noise. With recent advancements in high-speed transportation, railway companies are actively transitioning to new types of soundproof walls that offer improved noise reduction capabilities.

• Anchor bolts and the fastening points of the soundproof panels.
• Areas subjected to repeated exposure to strong wind pressure.
• Areas subjected to repetitive vibrations.
• Areas where concerns arise regarding loosening of screws due to natural wind loads or earthquakes.

• Reduced the work load by extending the cycle of maintenance because it was performed at night.
• Maintenance costs have also been greatly reduced.
