Thread type anchor rod reinforcing method for repairing longitudinal cracking of U-shaped bridge abutment
The invention relates to a thread type anchor rod reinforcing method for repairing longitudinal cracking of a U-shaped bridge abutment. When the thickness of a retaining wall of the bridge abutment is 1950-2350 mm in the cross bridge direction, a bridge abutment short wall, a bridge abutment barricade and a bridge abutment vertical wall of the longitudinally-cracked U-shaped bridge abutment are repaired. Before construction, a mudjacking type anchor rod reinforcing method is used for repairing bridge abutment side walls and filling soil of the bridge abutment so that the U-shaped bridge abutment can be in a safety state. In construction, a column of horizontal anchor rods in the cross bridge direction are driven into the bridge abutment short wall, inclined anchor rods in groups are driven into the bridge abutment vertical wall from the bridge abutment barricade, and reinforced concrete on the two sides of a longitudinal crack are anchored together; broken and weathered concrete is removed from the tail end line of the longitudinal crack, rebars, which are rusted and broken, of an original structure are cut away, rebars of a new structure are welded for repairing, full cement mortar is poured, and the appearance and the using function of the U-shaped bridge abutment can be restored. An operating method for the method is simple, the building cost of a project is low, repairing quality is high, and bridge deck traffic does not need to be interrupted in the whole construction process.
