[0003] Most of the existing noise barriers are pre-installed with multiple columns on the elevated crash pier, and a single or multiple sound insulation panels are installed between the two columns. For example, the Chinese utility model patent disclosed by publication number CN219793703U: a noise barrier assembly structure, the application provides a mounting seat on the lower side of the U-shaped bracket for installing the noise barrier body, the U-shaped bracket is connected to the base through the mounting seat, the mounting seat is fixed by bolts, and then the two adjacent U-shaped brackets are fixed by the connecting assembly, so that the noise barrier body can be quickly installed to form a row of integral structures, without the need to pre-install auxiliary components such as connecting columns during installation, thereby improving the installation efficiency. However, when assembling the sound barrier body and the U-shaped bracket in the application, firstly, the overall structural dimensions of the sound barrier body and the U-shaped bracket are large, which is not convenient for storage and transportation. At the same time, during installation, due to the large overall structural dimensions, the weight will also increase, so it is necessary to use external lifting equipment for coordinated installation, which fails to improve the installation convenience of the partition barrier body. In addition, when the sound barrier body in the application is connected, a limit plate is installed on the screw rods on the front sides of two adjacent U-shaped brackets, and a nut is also required to be set on the screw rod located above the limit plate, which further increases the installation time of the sound barrier body.
