Method for reinforcing cracked open-web hyperbolic stone arch bridge
The invention discloses a method for reinforcing a cracked open-web hyperbolic stone arch bridge. The method comprises the following steps that 1, arch bridge arch rib clay and a rock block weatheredlayer are cleaned, arch rib cracks are grouted after cleaning is completed, steel bars are planted on arch ribs after grouting is completed, a steel bar net is hung after steel bar planting is completed, reinforced concrete structures are poured on the four sides of an arch rib open-web section for reinforcement, and reinforced concrete structures are poured on the outer side face and the bottom face of an arch rib solid-web section for reinforcement; 2, reinforced concrete transverse partition plates are arranged at the joints of the arch columns on the two sides of the arch bridge and the arch ribs, the reinforced concrete transverse partition plates are connected with the two arch ribs of the arch bridge, and main reinforcements of the reinforced concrete transverse partition plates arewelded to embedded reinforcements of the arch ribs so as to reinforce the arch ribs; 3, a reinforced concrete structure is poured on the periphery of the arch rib arch upper stand column, and a concrete reinforcing layer is supplemented to the web arch ring.
本发明公开了一种有裂缝空腹式双曲石拱桥的加固方法，包括以下步骤，步骤一、清理拱桥拱肋粘土及块石风化层，清理完成后将拱肋裂缝灌浆，罐浆完成后在拱肋上植筋，植筋后挂钢筋网，拱肋空腹段四面浇筑钢筋混凝土结构加固，拱肋实腹段外侧面和底面浇筑钢筋混凝土结构加固；步骤二、拱桥两侧的拱上立柱与拱肋连接处设钢筋混泥土横隔板，所述钢筋混泥土横隔板连接拱桥的两个拱肋，所述钢筋混泥土横隔板的主筋与拱肋的预埋钢筋焊接从而加固拱肋；步骤三、拱肋拱上立柱四周浇筑钢筋混凝土结构，腹拱圈增补混凝土加固层。
