Totally-closed sound barrier for rail transit and mounting method of totally-closed sound barrier
The invention relates to the field of rail transit, in particular to a fully-closed sound barrier for rail transit, which comprises a first sound barrier and a second sound barrier, a first channel and a second channel are respectively formed on two sides between the first sound barrier and the second sound barrier, and silencing components are arranged in the first channel and the second channel. The silencing assembly is provided with a first sound absorption module and a second sound absorption module, and the first sound absorption module and the second sound absorption module are combined to form a streaming path for air circulation, so that air passes through the streaming path to circulate through the streaming path formed by the first sound absorption module and the second sound absorption module; noise energy is effectively reflected, scattered and absorbed for multiple times in the propagation process, so that the sound wave intensity is effectively attenuated, the noise level is greatly reduced, and the sound wave intensity is gradually weakened. The invention further relates to an installation method of the totally-closed sound barrier for the rail transit.
本发明涉及轨道交通领域，具体是涉及一种用于轨道交通的全封闭声屏障，包括第一声屏障和第二声屏障，第一声屏障和第二声屏障之间的两侧分别形成第一通道和第二通道，第一通道和第二通道中均设有消音组件，消音组件设有第一吸音模块和第二吸音模块，第一吸音模块和第二吸音模块之间组合形成供空气流通的绕流路径，本发明通过第一吸音模块和第二吸音模块所形成的绕流路径，使得空气经过绕流路径流通，有效地使噪声能量在传播过程中发生多次反射、散射和吸收，从而有效衰减声波强度，大幅度降低噪音水平，促使声波强度逐渐减弱。本发明还涉及一种用于轨道交通的全封闭声屏障的安装方法。
