[0002] Urban roads are roads that reach various regions of the city, are used for urban internal transportation and pedestrians, facilitate residents' lives, work and cultural and entertainment activities, and are connected to roads outside the city to bear external traffic. The construction of urban roads is usually carried out without affecting the normal passage of pedestrians or vehicles. During the road construction process, it is generally necessary to set up fences around the construction site for enclosure. On the one hand, it can prevent idle people from entering the construction site randomly, and on the other hand, it can ensure the safe progress of the construction site and the process. However, due to the lack of protection mechanisms in the existing fences, when an external vehicle hits the fence, it is easy to cause damage to the fence. Therefore, we propose a noise reduction and isolation device for road construction. Content of the Utility Model
