Abstract

The invention relates to a bridge modular expansion joint repairing method. Structural investigation is performed on an expansion joint in advance before construction, and the damage condition of theexpansion joint is determined so as to select a corresponding repairing method. The damage comprises the following conditions: 1, a middle beam is damaged and an expansion box is not damaged; 2, the middle beam is not damaged, and the expansion box is damaged; 3, partial expansion joint is damaged. Aiming at the damage condition, a local repairing method is adopted, the whole expansion joint doesnot need to be replaced, only the damaged part needs to be locally repaired or locally replaced, and on the premise that the integrity and the service life of the expansion joint are guaranteed, the cost is saved, the repairing efficiency is improved, the construction time is saved, and rapid traffic restoration is achieved. During repair construction, only one traffic lane is closed for maintenance, so that the traffic pressure of the bridge floor is relieved, and potential safety hazards are reduced.

Description

technical field

[0001] The invention relates to the technical field of expansion joint maintenance, in particular to a repair method for bridge modular expansion joints. Background technique

[0002] Expansion joints are one of the important components of the bridge structure. It is of great significance to ensure the stability of the bridge structure and ensure the safety of traffic by timely maintenance and repair work during use and maintaining the overall integrity of the expansion joints.

[0003] At present, there are the following disadvantages in the maintenance of expansion joints: 1. Maintenance is difficult. The construction needs to chisel out the concrete on both sides of the expansion joints on the road surface. Before maintenance, it is necessary to open grooves, remove garbage, and then replace and pour concrete. It takes a lot of time and manpower, and the garbage will cause environmental pollution. 2. The entire expansion joint needs to be replaced, which ...
