Concrete-filled steel tube composite cable bent tower and construction method thereof
The invention belongs to the technical field of bridge engineering, and particularly relates to a concrete-filled steel tube composite cable bent tower and a construction method thereof. By arranging bent main steel tubes, stay cables, stay cable positioning holes, auxiliary steel tube units for reinforcing, concrete units and anchoring steel plate units on the bearing platform, the purposes that the steel tube concrete composite cable bent tower is high in structural strength and can be used for a long time with high strength are achieved. The concrete-filled steel tube composite cable bent tower has the following advantages that firstly, the cable bent tower of the concrete-filled steel tube composite structure is large in structural strength, high in stability and high in bearing capacity and can be used in a bridge structure for a long time at high strength; secondly, the steel structure main body of the cable bent tower is high in self connection strength and uniform in stress, and the main steel tube and the auxiliary steel tube are not easy to bend; thirdly, concrete can be poured into the main steel tube and the auxiliary steel tube, and what is guaranteed is that the concrete-filled steel tube composite structure has the performance advantages of the main steel tube and the auxiliary steel tube; and fourthly, the whole construction process of the cable bent tower is simple, flexible, stable and safe.
本发明属于桥梁工程技术领域，尤其涉及一种钢管混凝土复合索塔及其施工方法。本发明通过在承台上设置弯曲主钢管、斜拉索、斜拉索定位孔、加强用副钢管单元、混凝土单元以及锚固钢板单元的方式，达到钢管混凝土复合索塔结构强度大，可以长期高强度使用的目的。本发明具有以下优点：第一，钢管混凝土复合结构的索塔，自身结构强度大、稳定性高、承载能力强，可以在桥梁结构中长期高强度使用；第二，索塔的钢结构主体自身连接强度大、受力均匀，主钢管和副钢管都不易弯曲；第三、主钢管和副钢管都可以浇筑混凝土，保证钢管混凝土复合结构可以兼具两者的性能优点；第四，索塔的整个施工过程简单灵活，稳定安全。
