Flange type steel box arch foot consolidation structure and construction method
The invention discloses a flange type steel box arch foot consolidation structure which comprises an arch ring foundation and an arch ring head arch section, arch support reinforced concrete is arranged between the arch ring foundation and the arch ring head arch section, and a lower flange plate is arranged in the arch support reinforced concrete; an upper flange plate is fixedly arranged at the bottom of the arch ring head arch section, and the upper flange plate is embedded in the top of the arch support reinforced concrete; an arch hinge structure is arranged between the upper flange plate and the lower flange plate, and the upper flange plate and the lower flange plate are correspondingly and evenly provided with a plurality of bolt holes and connected with high-strength bolt assemblies. The invention further discloses a construction method of the consolidation structure. By means of the structure, the problems that according to an existing arch ring welding extension consolidation scheme, welding operation is difficult, welding deformation is too large, welding residual stress is uncontrollable, arch seat concrete is prone to being burnt, and then durability is affected can be effectively solved, only part of high-strength bolt assemblies are additionally arranged, and other structural materials are not added, and the lower seat plate and the arch ring of the arch hinge structure can be consolidated.
本发明公开了一种法兰式钢箱拱脚固结结构，包括拱圈基础和拱圈首拱段，所述拱圈基础和拱圈首拱段之间设置有拱座钢筋混凝土，该拱座钢筋混凝土内设置有下法兰板；所述拱圈首拱段的底部固定设置有上法兰板，该上法兰板镶嵌设置于拱座钢筋混凝土的顶部；所述上法兰板和下法兰板之间设置有拱铰结构，两者还分别相对应均匀开设若干螺栓孔并连接有高强螺栓组件。本发明还公开了该固结结构的施工方法。应用本发明可有效解决现有拱圈焊接延长固结方案易带来的施焊作业困难、焊接变形过大、焊接残余应力不可控以及易灼烧拱座混凝土进而影响耐久性等问题，仅增设部分高强螺栓组件，不增加其它结构材料，即可实现拱铰结构下座板固结和拱圈固结。
