Reinforcing method for hinge joint of hollow slab of bridge
The invention provides a bridge hollow slab hinge joint reinforcing method which comprises the steps that a vertical steel plate is inserted into a hinge joint, meanwhile, a first U-shaped steel plate is hoisted to the top of a hollow slab top plate, a second U-shaped steel plate is hoisted to the bottom of a hollow slab bottom plate, and the top of the vertical steel plate is connected to the first U-shaped steel plate through a bolt; the bottom of the vertical steel plate is connected to the second U-shaped steel plate through a bolt; the second U-shaped steel plate is fixed to the bottom of the hollow slab bottom plate through a plurality of bolts arranged at intervals; a joint filling material is injected between the hinge joint and the vertical steel plate through a grouting hole reserved in the first U-shaped steel plate; a first layer of concrete is poured on the upper surface of the hollow slab top plate through a formwork, and a second layer of concrete is poured on the lower surface of the hollow slab bottom plate through a formwork; and bridge deck pavement is recovered, and overall reinforcement of the hollow slab bridge is completed. The method can improve the overall rigidity of the bridge and has good overall stability.
本申请提供一种桥梁空心板铰缝的加固方法，包括：将竖向钢板插进铰缝中，并同时将第一U型钢板吊装到空心板顶板的顶部上、将第二U型钢板吊装到空心板底板的底部上，并将竖向钢板的顶部通过螺栓连接于第一U型钢板上，将竖向钢板的底部通过螺栓连接于第二U型钢板上；将第二U型钢板通过多个间隔设置的螺栓而固定于空心板底板的底部上；通过第一U型钢板上预留的注浆孔向铰缝与竖向钢板之间注入填缝材料；通过支模板分别在空心板顶板的上表面上浇筑第一层混凝土、在空心板底板的下表面上浇筑第二层混凝土；恢复桥面铺装，完成空心板桥梁的整体加固。该方法可以提高桥梁整体的刚度，具有良好的整体稳定性。
