Reinforcing method for assembly type web arch ring of two-way curved arch bridge
The invention discloses a reinforcement method for an assembly type web arch ring of a two-way curved arch bridge. The reinforcement method comprises the following steps that the damage of the assembly type web arch ring is repaired; a reinforced concrete lattice is arranged on the bottom face of the assembly type web arch ring and comprises longitudinal ribs and transverse ribs which are distributed in a criss-cross mode. And after the construction of the reinforced concrete lattice on the bottom surface of the web arch ring is completed, carrying out surface sealing treatment on the exposed crack. The longitudinal ribs and the transverse ribs are combined in a staggered mode to form reinforced concrete lattices, the web arch ring stress shed frame is jointly formed, the bearing capacity of the web arch ring is effectively improved to meet the road network traffic requirement, meanwhile, the sparse transverse ribs do not completely limit the displacement coordination function of the web arch ring, and the functional characteristics of the web arch ring are well reserved; in the construction process of the reinforced concrete lattice reinforced assembly type web arch ring, bridge deck traffic can not be closed, the using amount of concrete is small, the reinforcing and modifying workload is small, the functional requirement for improving the bearing capacity of the web arch ring is met, and the obvious economic advantage of saving the manufacturing cost is achieved.
本发明公开了一种双曲拱桥装配式腹拱圈的加固方法，包括以下步骤：修补装配式腹拱圈病害；在装配式腹拱圈底面设置钢筋混凝土格构，钢筋混凝土格构包括纵横交错分布的纵肋和横肋；腹拱圈底面钢筋混凝土格构施工完成之后，对外露裂缝进行表面封闭处理。纵、横肋交错组合形成钢筋混凝土格构，共同构成腹拱圈受力棚架，有效提高腹拱圈承载能力以满足路网交通需求，同时稀疏设置的横肋并未完全限制腹拱圈承上启下的位移协调功能，很好地保留了腹拱圈的功能特性；本发明钢筋混凝土格构加固装配式腹拱圈施工过程中可不封闭桥面交通，混凝土用量小，加固改造工作量小，既满足提高腹拱圈承载力的功能需求，又具有明显的节约造价经济优势。
