Summary: | The invention relates to the technical field of bridge reinforcement, in particular to a hollow slab girder bridge shear reinforcement method without interrupting traffic, which comprises the following steps: S1, detecting and marking the position of a steel bar at the bottom of a hollow slab girder; s2, probing the current condition of the inner cavity of the hollow slab; a strip-shaped notch is formed in the bottom of the hollow slab beam, a partition structure is constructed in the inner cavity of the hollow slab through the strip-shaped notch, the partition structure divides the inner cavity of the hollow slab into a vacant area and two grouting areas, the vacant area is defined by the two partition structures, and the grouting areas are arranged close to the supporting beam pier; a grouting hole is formed in the hollow slab beam bottom, and a grouting filling material is input into the grouting area through the grouting hole till the grouting area is filled with the grouting filling material; s5, groove |
