On highways, particularly in urban areas, you’ll notice soundproofing walls lining both sides. These barriers are essential due to the significant noise generated by the constant flow of vehicles. As traffic grows more intense, the need for effective noise reduction becomes even more critical. Here’s a detailed look at how these highway sound barriers are installed:
First, the construction area needs thorough preparation. Any debris on the concrete collision wall must be removed completely. The high-strength chemical anchor bolts already fixed into the wall should be inspected carefully and any necessary adjustments made. Corrosion-resistant treatments should also be applied to ensure durability.
Next, the exact location for the sound barrier installation must be determined. Once the upright poles of the sound barrier are precisely positioned, a solid base is built atop the collision wall. This base serves as the foundation for the entire structure, much like the groundwork for any building project.
The third step involves the actual installation of the upright poles. These are typically H-shaped steel poles, which are welded together with flange base plates, internal and external reinforcement plates. They are then secured using high-strength chemical anchors. It’s crucial to align the poles correctly, ensuring they remain vertical and spaced appropriately. Tightening them securely with M20 nuts ensures stability post-construction.
Following this, the installation of the actual sound barrier panels begins. Using cranes or scaffolding, the panels are lifted slightly off the ground and held in place with auxiliary safety suspenders. The panels, whether acoustic or transparent, are slowly lowered into the grooves of the H-shaped poles. They are adjusted to the right height and then fully secured. Afterward, the panels are welded to the base, ensuring they adhere to the necessary standards. Any adjustments to the panels’ alignment and tension of the springs are made to guarantee stability and prevent gaps.
Finally, after the installation is complete, a comprehensive inspection is conducted to ensure everything is secure and functioning properly. Safety is paramount throughout the process, especially when working at heights. Any final touches, such as installing additional sound-absorbing or insulating components, are completed before the project is considered finished. Sound barriers not only reduce noise pollution but also enhance the overall safety and comfort of urban environments.
