Sound insulation and noise reduction wall structure
The invention belongs to the technical field of sound insulation and noise reduction, and particularly relates to a sound insulation and noise reduction wall structure. In view of the problem that thehighway noise processing effect is poor, the following scheme is presented. The wall structure comprises a first wall body and a second wall body. A noise reduction plate is arranged on one side of the first wall body, and rock wool is used as a main material of the noise reduction plate. A sound insulation layer is arranged on one side of the noise reduction plate, and the thickness of the soundinsulation layer is 3cm. Sound absorption foam is arranged on one side of the sound insulation layer. Sound absorption cotton is arranged on one side of the sound absorption foam. A first rubber buffer layer is arranged on one side of the sound absorption cotton, hollow glass is arranged on one side of the first rubber buffer layer, and a second rubber layer is arranged on one side of the hollowglass. The sound absorption foam and the sound absorption cotton are arranged, the sound absorption foam plastic is provided with holes and soft, low in hardness and resilience and good in sound absorption effect, the sound absorption cotton is made of polyester fibers and is easy to process and low in cost, the sound absorption foam and the sound absorption cotton are used in a combined mode, andthe diffusion capacity of noise is greatly reduced.
本发明属于隔音降噪技术领域，尤其是一种隔音降噪墙体结构，针对高速公路噪声处理效果差问题，现提出以下方案，包括第一墙体和第二墙体，所述第一墙体的一侧设置有降噪板，且降噪板采用岩棉作为主材，所述降噪板的一侧设置有隔音层，且隔音层的厚度为三厘米，所述隔音层的一侧设置有吸音泡沫，所述吸音泡沫的一侧设置有吸音棉，所述吸音棉的一侧设置有第一橡胶缓冲层，且第一橡胶缓冲层的一侧设置有中空玻璃，中空玻璃的一侧设置有第二橡胶层。本发明通过设置的吸音泡沫和吸音棉，吸音泡沫塑料开孔软泡，低硬度，低回弹，具有良好吸声作用，吸音棉是采用聚酯纤维，易加工且成本低，两者结合使用，大大减小了噪音的扩散能力。
