How to maintain high-speed sound barriers
High-speed highway sound barriers require maintaining a clean foundation surface, promptly removing debris and accumulated water. The shape of the highway sound barrier is determined by calculating the "equivalent height" of each sound barrier and the vertical sound barrier. We will detail the relevant content below.
Maintaining the high-speed sound barrier requires keeping the foundation surface clean and promptly removing debris and accumulated water. Check the ground drainage near the foundation to ensure smooth drainage and no water accumulation near the foundation. At the same time, repair and seal any cracks in the foundation and nearby pavement to prevent a large amount of surface water from seeping into the foundation, causing foundation settlement. Measures should be taken to maintain the stability of the foundation or the slope near the foundation. It is forbidden for any individual or unit to dig pits, remove soil, dump waste, conduct blasting operations, or engage in other activities that endanger the sound barrier around the foundation. Any actions that may damage the sound barrier should be stopped immediately. For problems such as erosion and peeling, honeycomb pockmarks, cracks, and exposed reinforcement on the foundation surface, repair should be done using cement mortar. If repair with cement mortar is difficult due to vehicle vibration, consider using epoxy resin or other polymer concrete for repair. For concrete voids, honeycombs, potholes, surface weathering, and peeling on the foundation, the loose parts should be removed first, and then repaired with high-strength concrete, cement mortar, or other materials. The new concrete should be dense, firmly bonded to the original structure, and have a smooth surface. The new concrete must be in place.
The choice of shape for high-speed sound barriers includes upright, folding, arc, and T-shaped arc-top types. For folding and curved types, the "equivalent height" of each baffle relative to the upright baffle should be calculated. In engineering, the equivalent elevation method is used to estimate the insertion loss of folding sound barriers. The equivalent height apex of the folding plate is the extension point of the height from the sound source to the apex of the folding plate and the vertical intersection point of the folding plate.
If height restrictions are reached or the noise reduction target value is high, the top structure of the high-speed highway sound barrier developed this year can be used. Currently, due to the different top structure forms, the additional noise values are also different, so it is difficult to determine the equivalent height. High-speed highway sound barriers also have a certain impact on passengers, such as blue and green, making people feel refreshed. The color selection of high-speed highway sound barriers should be integrated with the surrounding landscape environment, such as green blending with high-speed green belts, therefore, this should be considered when building high-speed highway sound barriers. At the same time, visual fatigue is also a factor to consider; usually, neutral gray can reduce the abruptness of the sound barrier. When coloring, choose neutral and gentle colors.
For residents close to the high-speed sound barrier, all colors of the high-speed sound barrier should be based on reducing feelings of oppression and blend into the surrounding scene as much as possible. It can also be combined with the local residents' cultural customs or local construction characteristics, using the high-speed sound barrier to achieve harmony with the surrounding scene and environment.
