Highways are often accompanied by soundproofing walls on both sides, especially in urban areas. With the increase in vehicle traffic and the resulting noise pollution, installing sound barriers has become essential. These barriers help reduce noise levels significantly, making the environment more pleasant for nearby residents. Below is a detailed explanation of the installation process for highway sound barriers:
First, prepare the construction site by thoroughly cleaning any debris from the surface of the concrete collision barrier. Inspect and trim all high-strength chemical anchor bolts attached to the concrete barrier, ensuring they are corrosion-resistant. This step ensures the stability and longevity of the structure.
Next, determine the exact location for installing the highway sound barrier. After marking the position of the upright poles, construct the base at the top of the collision barrier. This base serves as the foundation for the entire sound barrier system, similar to how a building needs a solid foundation.
The third step involves installing the upright poles. Combine H-shaped steel poles with their respective bases, reinforcing plates, and anchor them securely into the concrete using high-strength chemical anchors. Adjust the poles to ensure they are perfectly vertical, spaced correctly, and secured tightly with M20 nuts. This guarantees that the poles remain upright and stable throughout the construction process.
Following this, the actual installation of the sound barrier panels begins. Lift the panels slightly off the ground using cranes or scaffolding, then use an auxiliary safety suspension system to lower them gently. Align the panels within the grooves of the H-shaped steel poles and raise them to the desired height. Once aligned, remove the auxiliary suspension and secure the panels to their final position. Ensure proper welding of the poles to the base and fine-tune the panels for optimal alignment and stability.
Finally, inspect the entire sound barrier system upon completion. Look for any gaps or potential issues and address them immediately. Safety should always be a priority, especially when working at heights. After thorough checks, install additional components like sound-absorbing boards and insulation panels to enhance the barrier's effectiveness. Remember, maintaining safety standards throughout the process is crucial to ensure both worker safety and the quality of the finished project.
