Ecological combined sound insulation and noise reduction system for road
The invention discloses a highway ecological combined sound insulation and noise reduction system, and belongs to the technical field of highway noise reduction. The device comprises a base, a supporting frame is fixedly connected to the top of the base, a plurality of through holes are formed in the right side of the supporting frame, a noise reduction structure is arranged in the supporting frame, a sound insulation layer located on the left side of the noise reduction structure is arranged in the supporting frame, and a guide structure located on the right side of the supporting frame is arranged at the top of the base. Noise generated when a vehicle runs is guided and preliminarily absorbed through the guiding structure at the top of the base, the remaining noise enters the supporting frame, the noise reduction structure can refract and weaken the noise, and the sound insulation layer on the left side of the noise reduction structure can shield and eliminate the noise scattered in the reflection process; therefore, the effect of weakening the noise multiple times is achieved, and the problems that an existing noise reduction structure is single and is generally composed of a single-layer noise reduction structure, various noise reduction treatment cannot be conducted on the noise, and the environmental protection effect of the surrounding environment is seriously affected are solved.
本发明公开了一种公路生态组合式隔声降噪系统，属于公路降噪技术领域。本发明包括底座，底座的顶部固定连接有支撑框，支撑框的右侧开设有若干个通孔，支撑框的内部设置有降噪结构，支撑框的内部设置有位于降噪结构左侧的隔音层，底座的顶部设置有位于支撑框右侧的引导结构。本发明通过底座顶部的引导结构对车辆行驶时产生的噪音进行引导并对噪音进行初步吸收，剩余噪音进入支撑框，降噪结构能够对噪音进行折射削弱，降噪结构左侧的隔音层能够对反射过程中溢散的噪音进行遮挡消除，从而达到对噪音进行多次削弱的效果，解决了现有降噪结构较为单一，一般为单层降噪结构组成，无法对噪音进行多种降噪处理，严重影响了周围环境的环保效果的问题。
