The invention discloses a noise reduction barrier for municipal road and bridge construction. The noise reduction barrier comprises a body. Multiple connecting grooves are formed on one side of the body, and the other side of the body is connected with connecting blocks matched with the connecting grooves. Connecting plates are arranged in the middles of the connecting grooves and are fixedly connected with the inner walls of the connecting grooves, and connecting concave grooves are formed in the upper surfaces and the lower surfaces of the connecting plates. One end of each connecting blockis fixedly connected with the body, a first concave groove is formed in the other end of each connecting block, lifting blocks which are matched with the connecting concave grooves and are in invertedright trapezoid shapes are arranged in the first concave grooves, first springs are fixedly connected between the top ends of the lifting blocks and the first concave grooves, and the side faces, away from the body, of the lifting blocks are inclined faces in inverted right trapezoid shapes. According to the noise reduction barrier, a lightgage steel joist is adopted as a support, a calcium silicate composite sound absorption plate and sound absorption cotton are used for sound absorption, then a sound insulation board and sound insulation felt are used for sound insulation and noise reduction, and therefore noise generated during construction can be greatly lowered.
本发明公开了一种市政道路桥梁施工用降噪屏障，包括本体，所述的本体一侧开设有若干连接槽，另一侧连接有和连接槽相匹配的连接块；所述的连接槽中部设置有连接板，连接板和连接槽内壁固定连接，连接板的上下表面开设有连接凹槽；所述的连接块的一端和本体固定连接，另一端开设有第一凹槽，第一凹槽内设置有和连接凹槽相匹配的倒直角梯形状的升降块，升降块的顶端和第一凹槽之间固定连接有第一弹簧，所述的升降块远离本体的侧面为倒直角梯形的斜面；本发明通过轻钢龙骨作为支撑，通过硅酸钙复合吸音板和吸音棉进行吸音，然后通过隔音板和隔音毡进行隔音降噪，从而能够大大降低施工时产生的噪音。
