Hollow slab beam end grouting core filling reinforcing structure and reinforcing method
The invention discloses a hollow slab beam end grouting core filling reinforcing structure and method, the reinforcing structure comprises a hollow slab beam body, closed end plates and a cement-based material, a cavity is formed in the hollow slab beam body, the closed end plates are arranged at the two ends of the hollow slab beam respectively, two blocking parts are arranged in the cavity, and the cement-based material is arranged in the cavity. The two blocking parts are arranged close to the two closed end plates respectively, a filling cavity is formed between each blocking part and the corresponding closed end plate, and the filling cavities are filled with cement-based materials. The reinforcing method comprises the steps that the positions, close to the two closed end plates, in the hollow beam body are each provided with a blocking part, and a core filling cavity is formed between each blocking part and the corresponding closed end plate; and filling a cement-based material into the filling cavity. The hollow slab beam end grouting and core filling reinforcing structure has the advantages of being small in damage, rapid in construction, dense in bonding, efficient, economical and the like, and is particularly suitable for urban bridges which are large in traffic flow and difficult to close traffic to reinforce construction.
本申请公开一种空心板梁端部注浆填心加固结构及加固方法，加固结构包括空心板梁本体、封闭端板和水泥基材料，所述空心板梁本体内部具有空腔，所述空心板梁的两端分别设置封闭端板，所述空腔内设置两个封堵部，两个所述封堵部分别靠近两个所述封闭端板设置，每一所述封堵部与相应的封闭端板之间形成填心腔，所述填心腔内填充有水泥基材料。加固方法包括在空心梁本体内靠近两个封闭端板的位置分别安装一封堵部，每一封堵部分别与相应的封闭端板之间形成填心腔；向所述填心腔内加注水泥基材料。本申请的空心板梁端部注浆填心加固结构具有微损伤、快施工、密粘结、高效经济等优势，尤其适用于交通流量大，难以封闭交通来加固施工的城市桥梁。
