Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation barriers, in particular to a ventilation sound insulation barrier structure. Background Art

[0002] During the construction process, in order to avoid the impact of construction noise, sound barriers will be installed on both sides of the construction area. The sound barriers can effectively absorb and block the noise generated by the construction, reducing the noise pollution caused by the noise to surrounding residents.

[0003] Among the publicly authorized patents, in the Chinese patent with patent number "CN201921191975.1", a ventilation sound insulation barrier structure is disclosed, which relates to the technical field of sound insulation barriers, and is to solve the problem that the existing ventilation sound insulation barriers have a small sound absorption area, resulting in unsatisfactory sound absorption effect. A roadbed is installed at the lower end of the sound-absorbing column, and one end of the sound-absorbing column is embedded in the inside of the roadbed. A unit ventilation sound insulation barrier is installed between the two sound-absorbing columns, and there are six unit ventilation sound insulation barriers. Vacuum glass is installed inside the unit ventilation sound insulation barrier. A first glass plate is installed at the front end of the vacuum glass, and a second glass plate is installed at the rear end of the vacuum glass, and a vacuum cavity is provided between the second glass plate and the first glass plate. An aluminum alloy frame is installed outside the unit ventilation sound insulation barrier;

[0004] In the above device, by installing the columns on the roadbed, the position of the sound barrier can be limited. However, since the sound barrier is installed in the construction area, there are vehicles running and construction materials placed in the construction area. When the materials fall or the vehicles touch the sound barrier, the sound barrier will be hit and will fall. For this reason, we propose a ventilated sound barrier structure. Utility Model Content
