Buckling cable vibration suppression device of cable-stayed buckling system and construction method of buckling cable vibration suppression device
The invention discloses a cable-stayed buckling system buckle cable vibration suppression device and a construction method thereof, the device comprises a set of fastening rings and a set of vibration suppression ropes, the fastening rings are arranged on a buckle cable, the fastening rings are provided with a set of groove holes for a set of steel twisted ropes of the buckle cable to penetrate through, and the vibration suppression ropes are connected between the fastening rings and an arch bridge structure. The device further comprises a traction rope, one end of the traction rope is fixed to the arch bridge structure, the other end of the traction rope is fixed to the buckling tower, and the set of fastening rings are connected with the traction rope. The restraining rope is arranged in the middle of the buckle cable, the span of the buckle cable is reduced, the rigidity of the buckle cable is improved, the fastening rings are arranged on the buckle cable at equal intervals, the integrity of the buckle cable steel strands is improved, the amplitude and vibration frequency of the buckle cable can be effectively reduced, and therefore the problem that the buckle cable steel strands beat one another is effectively solved; rapid installation of the fastening ring and the vibration suppression rope can be achieved.
本发明公开了一种斜拉扣挂系统扣索抑振装置及其施工方法，其装置包括一组紧固环和一组抑振绳，所述紧固环设在扣索上，紧固环上设有用于扣索的一组钢绞绳穿过的一组槽孔，抑振绳连在紧固环和拱桥结构之间。还包括牵引绳，所述牵引绳的一端固定在拱桥结构上，牵引绳的另一端固定在扣塔上，一组紧固环均与牵引绳相连。本发明在扣索中间位置设置抑制绳，减少扣索跨径，提高扣索刚度，以及在扣索等间距设置紧固环，提高扣索钢绞线整体性，能有效减少扣索振幅和振动频率，从而有效避免扣索钢绞线互相拍打问题，并在紧固环之间设置牵引绳，其可实现紧固环和抑振绳快速安装。
