Description
Technical Field
[0001] This utility model relates to the field of sound barrier technology, and in particular to a single-screen limiting device for the top of an arc-shaped sound barrier and an arc-shaped sound barrier. Background Technology
[0002] The construction of numerous highways and the opening of urban light rail have greatly facilitated people's travel, but at the same time, residents living near these highways and light rail lines suffer from traffic noise. To improve the living environment of citizens, noise barriers are usually installed on both sides of the roads and around the light rail lines.
[0003] Curved sound barriers are commonly used in projects such as viaducts, railways, and subways, as they are aesthetically pleasing and offer good sound insulation.
[0004] The existing curved sound barrier is composed of a large number of individual panels spliced on a steel arch frame. During installation, the individual panels are installed sequentially from bottom to top on both sides of the steel arch frame. Theoretically, there is an installation gap of about 5mm between any two adjacent individual panels. However, after the multiple individual panels are actually installed, the actual cumulative installation gap of the installed individual panels makes it difficult to control the installation error of the top individual panel. This causes the actual position of the top individual panel to be lower or higher than the design position, making it difficult for the top individual panel to match the preset limiting structure.
[0005] The conventional solution is to enlarge or reduce the size of the top single screen to match the preset limiting structure. However, this makes it inconvenient to mass-produce and install the top single screen in a standardized manner, reducing the efficiency of production and installation. Utility Model Content
