3 ways to help solve the gap problem after the installation of the road noise barrier

Road noise barriers are used on both sides of the highway to reduce vehicle noise. There are more and more vehicles on the highway, which generates a lot of noise. Therefore, in order not to affect people's lives in the neighborhood, a road noise barrier was installed.

However, after some road noise barriers are installed, there will be gaps. In order not to affect the sound insulation effect of the products, we can adjust the gaps of road noise barriers, or use plastic strips or decorative strips for repairs.

1) The gap between the bridge saddle and the top of the collision pier is filled with cement slurry.

2) After the barrier is installed, use a 1:3 cement mortar to fill the gap between the lower acoustic panel and the base cap except for the area of ​​the drain hole of the H-shaped steel screen body support plate.

3) The front of the screen body As the blind rivet on the bead is higher than the surface of the bead, there is a certain gap between the contact surface of the H-pillar column building and the rubber seal can be used for sealing treatment, so that the effect is better.

Road sound barriers have large sound insulation: the average sound insulation is 37dB. Sound absorption coefficient is high: The average sound absorption coefficient is 0.84. High-speed sound insulation wall weather durability: The product has water resistance, heat resistance, anti-ultraviolet radiation, will not be caused by rainwater temperature changes to reduce performance or abnormal quality. The length of the sound barrier can be processed and produced as required. The sound barrier is beautiful: a variety of colors and shapes can be combined to coordinate with the surrounding environment to form a beautiful landscape.

The road sound barrier is characterized in that it includes a quadrilateral structure with a groove, a sound-absorbing plate, a protective panel with a sound-transmitting hole, a protection plate, and a damping plate. The sound-absorbing plate is inserted into a groove of a structure and is sound-absorbed. The inner device of the panel has a protective panel with a sound transmission hole, a damping plate is arranged on the outer side of the sound absorbing panel, a protective plate is arranged on the outer side of the damping panel, and the damping panel is a fire prevention panel. Because the device is in the open air, the sound-absorbing panel uses materials that are not afraid of water showers, such as polyurethane foam. The sound barrier uses fiberboards coated on both sides with a fireproof paint layer. The damping plate has a thickness of 4-8 mm. The sound absorbing plate has a thickness of 80-120 mm. The perforated protective panel is a perforated galvanized sheet with a thickness of 0.6-0.8 mm. The protective plate is a steel plate with a thickness of 1-2 mm. The grooved quadrilateral structure is limited by a steel plate having a thickness of 1 to 1.5 mm.

However, when road noise barriers are exposed to corrosive substances such as acid rain, they must be promptly dealt with, such as flushing with clean water. Reduce the impact of objects with large impact, so as to avoid distortion affecting the appearance and service life.
