Steel truss web totally-closed bridge
The invention discloses a steel truss web totally-closed bridge which comprises bridge piers, a box girder assembly and a sound insulation assembly. The multiple piers are evenly arranged at intervals. The side wall of the box girder assembly is a steel truss web, and the box girder assembly is arranged on a pier; openings located at the two ends and a vehicle channel located in the box girder assembly and communicated with the two openings are formed in the box girder assembly. The sound insulation assembly is detachably connected to the side wall and/or the top wall of the box girder assembly. As the bridge structure designed for the high-speed railway is set to be the totally-enclosed bridge, the box girder assembly is used as a main structure for bridge sound insulation, and the sound insulation assembly is used as an auxiliary structure for bridge sound insulation, when a high-speed train runs to the steel truss web totally-enclosed bridge, noise and pressure waves in the totally-enclosed bridge are reflected for multiple times in the box girder assembly; most noise is absorbed by the box girder assembly and the sound insulation assembly, and the noise generated when the high-speed train passes through the bridge is effectively reduced.
本发明公开了一种钢桁腹全封闭桥，包括桥墩、箱梁组件和隔声组件。多个桥墩均匀且间隔地设置。箱梁组件的侧壁为钢桁腹，箱梁组件设置于桥墩上；箱梁组件形成有位于两端的开口以及，位于内部且与两个开口相通的车辆通道。隔声组件可拆卸连接在箱梁组件的侧壁和/或顶壁上。由于将为高速铁路设计的桥梁结构设置为全封闭桥，箱梁组件作为桥梁隔声的主体结构，隔声组件作为桥梁隔声的辅助结构，在高速列车运行至钢桁腹全封闭桥时，全封闭桥内部噪音及压力波经过在箱梁组件内多次反射，大多被箱梁组件和隔声组件吸收，有效降低了高速列车通过桥梁时的噪声。
