Vertical rotation structure system of V-shaped main tower of extradosed hybrid beam cable-stayed bridge and construction method of vertical rotation structure system
The invention discloses an extradosed hybrid beam cable-stayed bridge V-shaped main tower vertical rotation structure system and a construction method thereof, and relates to the technical field of bridge construction, the extradosed hybrid beam cable-stayed bridge V-shaped main tower vertical rotation structure system comprises an opposite-pulling system and a supporting system, and further comprises a main cross beam, two cable-stayed bridge body assemblies are arranged at the top of the main cross beam, and each cable-stayed bridge body assembly comprises a tower beam combination section and a main beam combination section; a rotating hinge is arranged at the end part of the tower beam combination section, and the tower beam combination section is arranged on the main cross beam; the column foot is connected with the rotating hinge; the cross beams are arranged on the column feet, and the supporting system is used for supporting the cross beams and the column feet. Through work of the opposite-pull oil cylinders, lifting and vertical rotation of the cross beams and the column feet can be achieved in cooperation with the opposite-pull steel strands and the opposite-pull hinges, then construction of the V-shaped main tower is completed, and the purposes of reducing the use amount of large hoisting equipment, being good in economical efficiency, rapid in construction progress and the like are achieved.
本发明公开了一种矮塔混合梁斜拉桥V型主塔竖转结构体系及其施工方法，涉及桥梁施工技术领域，包括对拉系统和支撑体系，还包括主横梁，所述主横梁顶部设置有两个斜拉桥本体组件，所述斜拉桥本体组件包括：塔梁结合段，所述塔梁结合段端部设置有转动铰，所述塔梁结合段设置在主横梁上；柱脚，所述柱脚和转动铰连接；横梁，所述横梁设置在柱脚上，且支撑体系用于支撑横梁和柱脚。本发明能够通过对拉油缸的工作，配合对拉钢绞线和对拉铰实现横梁和柱脚的提升竖转，进而完成V型主塔的施工，达到减少大型吊装设备使用量，经济性好，施工进度快等目的。
