[0002] A sound-absorbing barrier is a soundproofing device inserted between the source and the receiver to block direct sound. This creates a significant additional attenuation of sound waves, thereby reducing the noise impact within the receiver's area. Sound-absorbing barriers are categorized as metal, non-metal, or composite. The ground portion of the barrier consists of three main components: the sound-absorbing screen, columns, and fastening devices. Traditional sound-absorbing screens vary in form due to their material, but their sound absorption function is generally achieved through fiber-based sound-absorbing materials.

Although the sound-absorbing and insulating barriers can be effectively installed, a wrench is required to repeatedly tighten the bolts during the installation process, and the screws have been lost, which is not efficient and convenient for installation. In addition, the bolts need to be installed one by one during the installation process, which takes a long time to install a large number of sound-absorbing and insulating barriers on the road, making the installation efficiency of the sound-absorbing and insulating barriers relatively low. Therefore, a sound-absorbing and insulating barrier that is easy to install is needed to solve the above problems. Utility Model Content
