The invention discloses a bridge section splicing joint structure and a construction method thereof, and relates to the technical field of bridge construction. The problems that a splicing seam of an existing prefabricated segment beam is prone to cracking, shearing force transmission of structural loads between the prefabricated segment beams is affected, and then the overall safety performance of a bridge is badly affected are solved. A convex shear key group is arranged on the end face of one side of each prefabricated segmental beam, a concave shear key group matched with the convex shear key group is arranged on the end face of the other side of each prefabricated segmental beam, every two adjacent prefabricated segmental beams are spliced in a butt joint mode through the convex shear key groups and the concave shear key groups, a binding agent is injected into a splicing seam for reinforcement, each convex shear key group is composed of a plurality of convex shear keys, and each convex shear key group is composed of a plurality of concave shear keys. The concave shear key group is composed of a plurality of concave shear keys, and main bodies of the convex shear keys and the concave shear keys are made of nodular cast iron materials.
本发明的一种桥梁节段拼装接头结构及其施工方法，涉及桥梁施工技术领域。针对现有预制节段梁拼接接缝处容易产生开裂，影响预制节段梁之间结构荷载的剪力传递，进而对桥梁整体的安全性能产生不良影响的问题。每个预制节段梁的一侧端面设有凸剪力键群，其另一侧端面设有与凸剪力键群相匹配的凹剪力键群，相邻两个预制节段梁通过凸剪力键群和凹剪力键群实现对接拼装，且拼装接缝处注入粘结剂进行加固，凸剪力键群由多个凸剪力键组成，凹剪力键群由多个凹剪力键组成，凸剪力键和凹剪力键的主体由球墨铸铁材料制成。
