Half-through arch bridge variable-width section construction method
The invention discloses a half-through arch bridge variable-width section construction method. The method comprises the steps of: hoisting a prefabricated cast-in-place hanging bracket through hoisting equipment to make the top surface of the cast-in-place hanging bracket flush with the bottom surface of a cast section; connecting the two sides of the cast-in-place hanging bracket to two sides ofan arch rib through a hanging tool system correspondingly; laying a template system used for casting a variable-width section on the top face of the cast-in-place hanging bracket, and casting concreteafter steel bars are bound to form the variable-width section; and after the concrete reaches a designed strength, dismounting the hanging tool system, and hoisting the cast-in-place hanging bracketaway through the hoisting equipment. According to the construction method, the cast-in-place hanging bracket is hoisted through hoisting equipment and connected to the cast section, then the cast-in-place hanging bracket and the arch rib are fixedly connected through the hanging tool system, therefore construction of the variable-width section is conducted on the cast-in-place hanging bracket. According to the method, the construction risk in the construction process of the variable-width section is reduced, the operation process is simplified, the construction period is shortened, and the maximization of economy, safety and practicability is realized.
本发明公开了一种中承式拱桥变宽段施工方法，其通过起吊设备起吊预制好的现浇吊架，使现浇吊架的顶面与已浇段的底面齐平；使用吊具系统将现浇吊架的两侧分别连接至拱肋的两侧；在现浇吊架的顶面上铺设用于浇筑变宽段的模板系统，绑扎钢筋后浇筑混凝土以形成变宽段；混凝土达到设计强度后，拆除吊具系统，通过起吊设备吊走现浇吊架。本发明通过起吊设备将现浇吊架吊起并与已浇段相接，再使用吊具系统固定连接现浇吊架与拱肋，从而在现浇吊架上进行变宽段的施工。本发明减小了变宽段施工过程中的施工风险，简化操作流程且缩短施工周期，实现了经济性、安全性和实用性的最大化。
