Construction method of variable-width and variable-height steel box girder support system in complex navigable water area
The invention discloses a construction method of a variable-width and variable-height steel box girder support system in a complex navigable water area, and relates to the technical field of bridge engineering construction. The construction method comprises the steps of construction preparation, surveying and setting out, steel pipe pile construction, steel trestle construction, foundation treatment, pushing temporary support construction, jig frame support assembly construction, warning navigation anti-collision pile arrangement and support removal. According to the steel box girder support system, the pushing temporary pier structures and the assembly jig frame structure supports are all connected through flange plate bolts by adopting steel pipe piles and steel pipe stand columns, supporting system components which can be turned over and reused are formed, the construction speed is high, the operation feasibility is high, and the construction method is suitable for construction of the variable-width and variable-height steel box girder support system in the complex navigable water area; the temporary buttress and the treated road surface are fixed through the embedded screw, the embedded screw is connected with the embedded steel plate in a welded mode, the construction speed is increased, the construction efficiency is improved, and compared with a traditional construction method, the construction cost is comprehensively saved by about 13%.
本发明公开一种复杂通航水域变宽变高钢箱梁支架体系施工方法，涉及桥梁工程施工技术领域。本发明的施工方法包括施工准备、测量放线、钢管桩施工、钢栈桥施工、基础处理、顶推临时支架施工、拼装胎架支架施工、警示导航防撞桩设置、支架拆除。本发明的钢箱梁支架体系，顶推临时墩结构、拼装胎架结构支架均采用钢管桩，钢管立柱采用法兰盘螺栓连接，构成可周转并重复利用的支撑体系构件，施工速度快，操作可行性高，适用于复杂通航水域变宽变高钢箱梁支架体系的施工；临时支墩与处理后路面采用预埋螺杆固定，预埋螺杆与预埋钢板焊接连接，加快了施工速度，提高了施工效率，与传统施工方法相比综合节约造价13％左右。
