The invention discloses a road sound insulation windshield which comprises two sound insulation screens and a perspective window located between the two sound insulation screens, each sound insulation screen comprises two reinforcing layers, the opposite sides of the two reinforcing layers are fixedly connected with sound insulation plates, a sound absorption plate is fixedly connected between the two sound insulation plates, a cavity is formed in the sound absorption plate, and the two reinforcing layers are fixedly connected with the perspective window. The cavity is filled with sound-absorbing particles, the strong layer is formed by a frame structure of a steel structure, the inner side of the strong layer is supported and fixed through a plurality of isolation rods, the strength is improved, then the inner sides of grids formed by the isolation rods are filled with sound insulation cotton, the overall structure is reinforced while the sound insulation and noise reduction performance of the foundation is guaranteed, the strength of the foundation is improved, and the service life of the foundation is prolonged. The sound insulation board is a polyester fiber board, the overall sound insulation performance of the sound insulation screen is effectively improved, the sound absorption board is made of expanded pearl wool and composed of countless independent bubbles generated by low-density polyethylene through physical foaming, and noise transmission is reduced.
本发明公开了一种道路隔音挡风屏，包括两个隔音屏和位于两个隔音屏之间的透视窗，所述隔音屏包括两个加强层，两个所述加强层相对的一侧均固定连接有隔音板，两个所述隔音板之间固定连接有吸音板，所述吸音板的内部设置有空腔，所述空腔内部填充有吸音颗粒，强层为钢结构的框体结构构成，其内侧通过多个隔离杆进行支撑固定，提高强度，然后在隔离杆构成的方格内侧再填充隔音棉，在保证基础的隔音降噪性能同时加强整体结构，使其强度提高，延长使用寿命，隔音板为聚酯纤维板，有效提高隔音屏整体隔音性能，吸音板为膨胀珍珠棉，由低密度聚乙烯脂经物理发泡产生无数的独立气泡构成，降低噪音传播。
