5 key points of bridge bearings maintenance

1. Daily inspection

Bridge bearings need regular inspection to check whether there is deformation, crack, loosening and other conditions, and timely maintenance and replacement. Especially when large vehicles pass over the bridge, special inspections should be carried out on the supports.

2. Cleaning and maintenance
The cleaning and maintenance of the bridge bearings are very important, and it is necessary to regularly clean the bearings, remove dust and debris, and prevent dust and other debris from entering the bearings, affecting the service life and performance of the bearings.

3. lubrication maintenance
The lubrication and maintenance of bridge bearings are also a very important part. Regular lubrication of the support can reduce the friction and wear of the bearings and extend the service life of the bearings. At the same time, lubrication can also reduce noise, reduce vibration, and improve the operating efficiency and safety of the bridge.

4. anti-corrosion maintenance
The bridge bearings are exposed for a long time, which is easy to be corroded by seawater, rain, oxidation and so on. Therefore, it is necessary to carry out anti-corrosion maintenance on the bearings and extend the service life of the bearings. It is recommended to use anti-corrosion paint for treatment, regularly check the condition of the paint, and timely maintenance and replacement.

5. strengthen management
The maintenance of bridge bearings need to strengthen management, establish bridge bearings files, and record the use, maintenance and replacement of the bearings. Check the bearings regularly, find the problem in time and deal with it to ensure the safe operation of the bridge.
