Vortex vibration suppression mechanism for box girder bridge
A box girder bridge vortex-induced vibration suppression mechanism is used for a box girder bridge formed by connecting a plurality of hollow box girders, the box girder bridge vortex-induced vibration suppression mechanism comprises a pump station, a vortex-induced vibration detection device arranged on the box girder bridge and a pouring water tank, the pump station takes water from a river channel below the box girder bridge, the pouring water tank is arranged in an inner cavity of the box girder, and the pump station is connected with the box girder. A water inlet and a water outlet are formed in the filling water tank, the water inlet of the filling water tank is connected with a water outlet pipeline of the pump station, the water outlet is formed in the bottom of the filling water tank and provided with a drainage pipeline leading to the outside of the box girder, and an electric drainage valve is arranged on the drainage pipeline; and the pump station, the vortex vibration detection device and the electric drainage valve are all electrically connected with the central controller. The invention provides a box girder bridge vortex-induced vibration suppression mechanism which can dynamically adjust the natural vortex-induced vibration frequency of a bridge and prevent vortex-induced vibration.
一种箱梁桥涡振抑制机构，用于由多节中空的箱梁连接而成的箱梁桥，该箱梁桥涡振抑制机构包括泵站、设置在箱梁桥上的涡振检测装置以及灌注水箱，所述泵站从箱梁桥下方的河道取水，所述灌注水箱设置在箱梁的内部空腔中，灌注水箱上设置有进水口及出水口，灌注水箱的进水口与泵站的出水管道连接，出水口设置在灌注水箱底部，出水口设置有通往箱梁外部的排水管道，排水管道上设置有电动排水阀；所述泵站、涡振检测装置以及电动排水阀均与中央控制器电性连接。本发明提供了一种箱梁桥涡振抑制机构，可以动态调整桥梁的固有涡振频率，防止涡振的发生。
