Prefabricated box girder approach bridge jacking replacement support structure and construction method thereof
The invention relates to a prefabricated box girder approach bridge jacking replacement support structure and a construction method thereof. The method mainly comprises a prefabricated box girder, a self-stabilizing hoop body, a limiting device, a moving trolley, a steel pipe auxiliary supporting hoop jacking platform technology, a fixed cover beam support-free jacking technology, a steel box girder wet joint limiting device, a hanging type construction platform technology and a support moving, falling and replacing technology. The construction method comprises the following main construction steps: limiting the steel box girder; building a construction platform; jacking the steel box girder; and replacing the support. According to the prefabricated box girder approach bridge jacking replacement support structure and the construction method, the approach bridge section box girder jacking technology is provided, the construction procedure is simplified, the labor input is reduced, the bridge replacement support installation efficiency is improved, and the construction difficulty is reduced.
本发明涉及一种预制箱梁引桥顶升更换支座结构及其施工方法，主要包括预制箱梁、自稳抱箍体、限位装置、移动小车、钢管辅助支撑抱箍顶升平台技术、固定于盖梁无支架顶升技术、钢箱梁湿接缝限位装置、吊挂式施工平台技术、支座移动落位更换技术。主要施工步骤包括：钢箱梁限位；施工平台搭设；钢箱梁顶升；支座更换施工。本发明涉及的一种预制箱梁引桥顶升更换支座结构及施工方法，提出了引桥段箱梁顶升技术，简化了施工工序，降低了人工投入，提高了桥梁更换支座安装效率，降低了施工难度。
