Method for quickly dismantling upper structure of truss arch bridge
The invention relates to the technical field of bridge dismantling construction, in particular to a method for quickly dismantling a superstructure of a truss arch bridge, which comprises the following steps of: (A) dismantling a bridge floor accessory structure including handrails and sidewalk slabs; (B) a temporary supporting system (a) is arranged; (C) removing the bridge deck pavement and the slightly bent plate; (D) dividing the arch pieces, and cutting and separating the arch pieces; and (E) the arch piece is hoisted to a designated position. According to the method, the dismantling construction sequence of a traditional truss arch bridge structure is optimized, by arranging the temporary supporting system (a), the situation that arch pieces possibly overturn in the lateral direction in the dismantling process of the truss arch bridge upper structure is avoided, the stability of the arch pieces in the dismantling process is guaranteed, the safety of the construction process is guaranteed, meanwhile, the construction procedure is optimized, and the construction efficiency is improved. And the construction period is shortened, the construction efficiency is improved, the construction cost is reduced, and the method can be popularized in actual engineering.
本发明涉及桥梁拆除施工技术领域，具体涉及一种快速拆除桁架拱桥上部结构的方法，包括以下步骤：(A)拆除桥面附属结构包括栏杆以及人行道板；(B)设置临时支撑系统(a)；(C)拆除桥面铺装以及微弯板；(D)划分拱片，切割分离各个拱片；(E)吊运拱片至指定处。本发明中，优化了传统桁架拱桥结构的拆除的施工顺序，通过设置临时支撑系统(a)，避免了桁架拱桥上部结构拆除过程中可能出现拱片侧向倾覆的情况，保证了拆除过程中拱片的稳定性，确保了施工过程的安全，同时也优化了施工工序，缩短了施工工期，提高了施工效率，降低了施工成本，可以在实际工程中推广。
