Abstract

The invention relates to the technical field of bridge repair, in particular to a treatment method for an expansion joint of a bridge. The method comprises the following steps of inspecting the expansion joint of the bridge at a preset time period; positioning a damaged part in an expansion structure; lifting a support beam, and replacing the damaged part. According to the treatment method for the expansion joint of the bridge, the expansion joint of the bridge is periodically inspected, and whether a part in the expansion structure in the expansion joint of the bridge is damaged or not is timely discovered; a complete set of expansion joint is not required to be integrally dug out to cause damage to a concrete structure at the expansion joint of the bridge, so that the expansion joint is not required to be integrally replaced, the bridge of which the complete set of expansion joint is to be replaced is not required to be controlled for 30 to 45 days, the maintenance cost is reduced, the bridge can be maintained within a short time (about 2 to 3 days), and the traffic safety and smoothness of the bridge are ensured.

Description

technical field [0001] The invention relates to the technical field of bridge repairs, in particular to a treatment method for bridge expansion joints. Background technique [0002] Expansion joint refers to a structural joint set along the appropriate part of the construction joint direction of the building or structure to prevent the structural cracks or damage of the building components due to climate temperature changes (heat expansion, cold contraction). [0003] Bridge expansion joints refer to expansion joints between specific beam sections, between beam sections and abutments, or at hinged positions of bridges in order to meet the requirements of bridge deformation, and expansion joints are provided with expansion joints. The expansion joints are required to be free to expand and contract in two directions parallel to and perpendicular to the bridge axis, firm and reliable, and the vehicles should run smoothly without sudden jumps and noises. [0004] The telescopic...
