桥墩是桥梁的主要承载结构,长期承受桥梁结构自重以及汽车荷载作用,随着超载车辆的日益增加,建成通车的桥梁出现各种损伤或疲劳破坏,为确保桥梁结构安全,需要采取措施对损伤的桥墩进行处理,同时,需对桥跨结构进行临时支撑和保护。本文重点研究了在桥墩处治工程中梁板的顶升技术,仔细分析和设计了顶升支架以及置换装置,避免了顶升千斤顶长时间工作,为处治工程创造安全施工环境,同时避免因顶升作业对桥跨结构带来损伤,对类似工程具有一定的参考应用价值。
Bridge pier is the main bearing structure of the bridge, long-term bear the weight of the bridge structure and the role of car load, with the increasing overload vehicles, the bridge opened to traffic caused by various damage or fatigue damage, in order to ensure the safety of the bridge structure, the need to take measures to damage Bridge pier for processing, at the same time, the need for temporary support and protection of the bridge structure. This paper focuses on the lifting technology of the beam plate in the pier treatment project, carefully analyzes and designs the jacking bracket and the replacement device, avoids the jack jack working for a long time, creates a safe construction environment for the treatment project, Work on the bridge structure damage, for a similar project has a certain reference value.
