Folding-line-shaped bridge sound barrier stand column, sound barrier system and construction method
The invention discloses a broken-line-shaped bridge sound barrier stand column, a sound barrier system and a construction method.The sound barrier system comprises a bridge and guardrail side wall steps arranged on the two sides of the bridge in the length direction, and a plurality of broken-line-shaped bridge sound barrier stand columns are sequentially arranged on the tops of the guardrail side wall steps in the length direction; the broken-line-shaped bridge sound barrier stand column comprises a bridge guardrail stand column body and broken-line-shaped sound barrier stand column combination bodies, the bridge guardrail stand column body is located on the inner side of the broken-line-shaped sound barrier stand column combination bodies, and a silencing plate assembly is assembled between every two adjacent broken-line-shaped sound barrier stand column combination bodies in a matched mode. The top ends of the bridge guardrail stand columns are correspondingly and fixedly provided with guardrail stand column connecting plates, and the guardrail stand column connecting plates are connected with the inner sides of the broken line sound barrier stand column assemblies through supporting pull rod assemblies. The bridge sound barrier stand column is convenient to construct and assemble and has the good transverse wind resistance performance, the fold-line-shaped contour with the good aerodynamic performance is adopted, the aerodynamic shape of a bridge is improved, wind-induced vibration is reduced, and driving safety under crosswind is guaranteed.
本发明公开了一种折线形桥梁声屏障立柱及声屏障系统、施工方法，其声屏障系统包括桥梁和设于桥梁长度方向两侧的护栏边墙台阶，护栏边墙台阶顶部沿长度方向依次设有若干个折线形桥梁声屏障立柱，折线形桥梁声屏障立柱包括桥梁护栏立柱和折线声屏障立柱组合体，桥梁护栏立柱位于折线声屏障立柱组合体内侧，相邻两个折线声屏障立柱组合体之间配合装配有消声板组件；桥梁护栏立柱顶端对应固定设有护栏立柱接板，护栏立柱接板与折线声屏障立柱组合体内侧通过支撑拉杆组件连接。本发明提供一种施工组装便利、具有良好横向抗风性能的桥梁声屏障立柱，采用气动性能良好的折线形轮廓，改善桥梁气动外形，减小风致振动，保障了横风下行车安全。
