Assembled butt-joint type overpass noise reduction and isolation sound barrier
The invention relates to the technical field of noise reduction barriers, and discloses an assembled butt joint type overpass noise reduction and isolation sound barrier which comprises a base, a barrier body is fixedly connected to the center axis of the top of the base, a plurality of semicircular pipes are fixedly connected to the outer surface of the right side of the barrier body, and a plurality of noise reduction holes are formed in the outer surfaces of the semicircular pipes. According to the assembled butt-joint type overpass noise reduction and isolation sound barrier, when a vehicle runs on the overpass at a high speed, sound can be absorbed through the S-shaped curved elastic plates, part of the sound can be reflected through the shapes of the S-shaped curved elastic plates, then the noise reduction purpose is achieved, meanwhile, due to the fact that the vehicle runs at the high speed, the two sides have strong wind power, and the noise reduction effect is good. And the S-shaped curved elastic plate can be deformed under the action of wind power, so that the S-shaped curved elastic plate can act on the interior of the internal sound absorption cavity under the deformation effect, noise is offset, and the noise reduction effect of the device is further enhanced.
本发明涉及降噪屏障技术领域，且公开了一种组装对接式立交桥降噪隔离声屏障，包括底座，所述底座的顶部中轴处固定连接有屏障本体，所述屏障本体的右侧外表面固定连接有若干半圆管，所述半圆管的外表面开设有若干个降噪孔。该组装对接式立交桥降噪隔离声屏障，当车辆在其立交桥上高速行驶时，声音会通过S型曲形弹性板进行吸收，且由于S型曲形弹性板的形状可以对部分声音进行反射，进而达到降噪的目的，同时，由于车辆的高速行驶会使两侧有较强的风力，进而在风力作用下可以使S型曲形弹性板发生变形，进而在此变形效果下可以作用在内部的吸声腔的内部，进而对噪声进行抵消，进一步的增强该装置的降噪效果。
