Concrete hollow slab beam shear-resistant reinforcing method without interrupting traffic
The invention discloses a concrete hollow slab girder shear-resistant reinforcement method without interrupting traffic, and relates to the technical field of bridge reinforcement. Comprising the following steps that 1, reinforcing areas are divided, specifically, the hollow slab girder is divided into a plurality of reinforcing areas according to the number of lanes on a bridge floor, 2, trepanning is conducted, specifically, a plugging formwork inserting hole, a pouring hole and a vibrating hole are formed in the top of the hollow slab girder in the first reinforcing area in the length direction of the hollow slab girder; thirdly, a plugging formwork is installed, and the plugging formwork is inserted into the inner cavity of the hollow slab beam through the plugging formwork insertion hole; fourthly, reinforcing materials are poured, specifically, the reinforcing materials are poured into an inner cavity of the hollow slab beam; fifthly, the plugging formwork is dismantled; sixthly, plugging formwork insertion holes are repaired; and the traffic of the first reinforcing area is recovered, the second reinforcing area is closed, and the work from the second step to the sixth step is repeated. According to the reinforcing method, the shear resistance of the hollow slab bridge can be improved, smooth traffic can be kept, and normal passing of vehicles and pedestrians is not affected.
本发明公开了一种不中断交通的混凝土空心板梁抗剪加固方法，涉及桥梁加固技术领域。包括以下步骤：步骤一、划分加固区，根据桥面车道数，将空心板梁划分为多个加固区，步骤二、开孔，在第一个加固区的空心板梁顶部沿其长度方向分别开凿封堵模板插入孔、灌注孔和振捣孔；步骤三、安装封堵模板，将封堵模板通过封堵模板插入孔插入空心板梁内部空腔；步骤四、灌注加固材料，向空心板梁内部空腔灌注加固材料；步骤五、拆除封堵模板，步骤六、修复封堵模板插入孔；恢复第一个加固区的交通，封闭第二个加固区，重复步骤二至步骤六的工作。本发明提供的加固方法，既可以提升空心板桥的抗剪性能，也能保持交通流畅，不影响车辆与行人的正常通行。
