Steel-concrete hybrid beam continuous rigid frame bridge suspension casting and hoisting construction method
The invention discloses a steel-concrete hybrid beam continuous rigid frame bridge suspension casting and hoisting construction method which comprises the steps that a sliding way is built on the top face of a T-shaped beam foundation section, and a formwork system of integrated equipment is suspended on the side portion of the T-shaped beam foundation section through a suspension hoisting system; a formwork system is in place on the side portion of the foundation section of the T-shaped structure beam, section beam steel bars are bound, and concrete is poured; the main truss slides forwards by the length of one section and is in place; the follow-up section beam is circularly constructed to the previous section of the rigid-concrete combined section; the steel structure of the steel-concrete combined section is transported to a bridge through water, and then the steel structure of the steel-concrete combined section is lifted to the designed elevation and positioned through a hoisting system of the integrated equipment; a formwork system is in place at the position of the steel-concrete combined section, and concrete is poured; and the integrated equipment is moved to the lifting position of the mid-span steel beam, the mid-span steel beam is lifted to the designed elevation and positioned through the hoisting systems of the two sets of integrated equipment, and full-span closure is achieved. Therefore, construction cost is reduced and construction efficiency is improved.
本发明公开了一种钢混混合梁连续刚构桥悬浇吊装施工方法，其包括在T构梁基础段顶面搭建滑道，一体化设备的模板系统通过悬挂起升系统悬吊于T构梁基础段侧部；模板系统在T构梁基础段侧部就位，绑扎节段梁钢筋并浇筑混凝土；主桁架向前滑移一个节段长度并就位；循环施工后续节段梁至刚混结合段的前一个节段；钢混结合段的钢结构通过水运至桥处，然后通过一体化设备的吊装系统将钢混结合段的钢结构起升至设计标高并定位；模板系统在钢混结合段位置就位并浇筑混凝土；将一体化装备移动至中跨钢梁起升位置，通过两组一体化装备的吊装系统共同将中跨钢梁起升至设计标高并定位，实现全跨合龙。从而减少施工成本和提高施工效率。
