Description

Technical Field

[0002] With the rapid development of my country's transportation industry, the traffic volume in cities is increasing day by day. Increasing the traffic capacity of existing bridges is an important and urgent task at present. As a common renovation method, the key problem faced by widening reconstruction is the staggered width connection technology of new and old bridges. The structure of the connection area between the new and old bridges directly affects the durability and safety of the bridge after widening. Under the influence of complex factors such as concrete shrinkage of the new and old beams, creep difference, foundation settlement, and load at the splicing part, inappropriate longitudinal joint structure will lead to cracking, water leakage, fragmentation and other diseases. In the process of bridge widening reconstruction, considering the problems of the river crossing the bridge obliquely or the intersection at the pier, the new bridge and the old bridge are often arranged with staggered holes, and the upper structure is staggered and widened. When the existing wide bridge longitudinal wet joint connection is used, it is generally connected by welding with steel bars, and because this connection method does not have any docking guide structure, it is difficult to accurately dock during welding. For this reason, we propose a longitudinal wet joint connection structure for staggered splicing of wide bridge structures. Utility Model Content
