Reinforced concrete V-shaped pier steel frame bridge micro-bending plate bridge surface reinforcing method
The invention relates to the technical field of steel frame bridge structures, in particular to a reinforced concrete V-shaped pier steel frame bridge micro-bending plate bridge surface reinforcing method. The method comprises the following steps of dismantling a current bridge deck slab, arranging a plurality of I-beams, mounting a suspended formwork, pouring a first layer of steel fiber concreteand pouring a surface layer of steel fiber concrete. According to the reinforcing method, the micro-bending plate bridge surface structure of the reinforced concrete V-shaped pier steel frame bridgecan be repaired, the safety of the steel frame bridge is improved, and the service life is prolonged; the first layer of steel fiber concrete and the surface layer of steel fiber concrete are prefabricated in an integral cast-in-place mode instead of a striding and blocking mode, and the problem that cracks are generated due to the fact that boundary conditions of a prefabricated micro-bending plate are prone to changing is solved from the structure source; segmented drilling is combined with a cutting machine and a long-arm crane for bridge deck dismantling, the load in the construction period is reduced, and damage to a bridge main body structure is reduced to the maximum extent.
本发明涉及钢架桥结构技术领域，尤其是一种钢筋混凝土V形墩钢架桥微弯板桥面加固方法。本发明包括拆除现状桥面板、设置多道工字钢、吊模安装、浇筑第一层钢纤维砼和浇筑面层钢纤维砼几个步骤。本发明的加固方法能够修复钢筋混凝土V形墩钢架桥微弯板桥面结构，提高钢架桥安全性和使用寿命；第一层钢纤维砼和面层钢纤维砼采用整体现浇替换分跨分块预制，从结构源头上解决了预制微弯板的边界条件的容易变化，进而产生裂缝的问题；桥面拆除采用分段钻孔结合切割机与长臂起重机，减小了施工期的荷载，最大程度降低对桥梁主体结构的损伤。
