Existing hollow slab bridge reinforcing system and construction method thereof
The invention discloses an existing hollow slab bridge reinforcing system and a construction method thereof, perforated steel boxes are distributed on the lower side of an existing hollow slab bottom plate along each row of hinge joints and are transversely aligned, and the perforated steel boxes are fixed on the existing hollow slab bottom plate through embedded bolts on the top surface and sticky steel structural adhesive to form hinge joint reinforcing steel members; transverse perforations and longitudinal perforations are distributed in the side surfaces of the perforated steel box; the transverse prestressed steel strands penetrate through the corresponding transverse through holes in the transverse through hole steel boxes in the transverse through hole steel boxes in the transverse through hole steel boxes in the transverse through hole steel boxes in the transverse through hole steel boxes in the longitudinal through hole steel boxes in the longitudinal through hole steel boxes in the longitudinal through hole steel boxes in the longitudinal through hole steel boxes in the longitudinal through hole steel boxes in the longitudinal through hole steel boxes in the longitudinal through hole steel boxes in the longitudinal through hole steel boxes in the longitudinal through hole steel boxes in the longitudinal through hole steel boxes; the post-poured ultra-high performance concrete is located on the lower side of a bottom plate of the existing hollow slab and covers the perforated steel boxes, the transverse prestressed steel strands and the longitudinal prestressed steel strands, and the whole system and the existing hollow slab are connected into a whole to be stressed. The system can repair the existing hollow slab hinge joint and improve the transverse and longitudinal bearing capacity.
本发明公开了一种既有空心板桥加固系统及其施工方法，穿孔钢箱在既有空心板底板下侧沿各列铰缝分布且横向对齐，穿孔钢箱通过顶面的植入螺栓和粘钢结构胶固定在既有空心板底板上形成铰缝加固钢构件，穿孔钢箱侧面分布有横向穿孔和纵向穿孔；横向预应力钢绞线穿过各列横向穿孔钢箱上各列对应的横向穿孔后张拉施加预应力、纵向预应力钢绞线穿过各列纵向穿孔钢箱上各列对应的纵向穿孔后张拉施加预应力，将所有铰缝加固钢构件连成一个整体；后浇超高性能混凝土位于既有空心板底板下侧且覆盖穿孔钢箱、横向预应力钢绞线和纵向预应力钢绞线，将整个系统与既有空心板连接成一个整体受力。该系统能修复既有空心板铰缝并提高横纵向承载能力。
