Stay cable structure of cable-stayed bridge
The invention provides a stay cable structure of a cable-stayed bridge. The stay cable structure comprises a stay cable body and an anchoring device, the two ends of the stay cable body are provided with PE sheath stripping sections exposed out of stay cable steel wires, the stay cable body is fixed to the anchoring device through the stay cable steel wires of the PE sheath stripping sections, and a sleeve is arranged between the anchoring device and a PE sheath and used for protecting exposed stay cable steel wires; an air supply ring is arranged on the section of the PE sheath of the stay cable body and is arranged in the circumferential direction of the stay cable body, and a plurality of air supply pipes are arranged between the air supply ring and the anchoring device, so that dry air can enter the stay cable body from the air supply pipes. According to the stay cable structure, dry air is conveyed into the stay cable body through the multiple air supply pipes, the corrosion humidity of the stay cable body is greatly reduced, the multiple air supply pipes are arranged to reduce the risk that the air supply pipes are blocked, and therefore the stay cable structure is good in dehumidification effect, long in service life and low in maintenance cost.
本发明公开了一种斜拉桥梁的斜拉索结构，包括斜拉索本体和锚紧装置，斜拉索本体的两端具有裸露出拉索钢丝的PE护套剥离段，斜拉索本体借助PE护套剥离段的拉索钢丝固定于锚紧装置上，锚紧装置与PE护套之间设置有套管，用于保护裸露的拉索钢丝；斜拉索本体的PE护套断面上设置有送气环，送气环沿斜拉索本体的周向方向设置，送气环与锚紧装置之间布置有多根送气管，使得干空气能够从送气管进入到拉索本体内。本发明通过多根送气管将干空气输送进入斜拉索本体内，大大降低拉索本体的腐蚀湿度，并且通过设置多根送气管，降低送气管堵塞的风险，使得本发明的斜拉索结构除湿效果较佳，使用寿命长，维修成本低。
