Maintenance
In order to ensure the safety of customers continue to fabricated steel use, southern steel company to provide maintenance service to customers regularly reminded, and according to the customer in the prefabricated bridge in practical use, corrosion, deformation degree, to provide maintenance services and maintenance.
- The South Bailey bridge maintenance program:
- Prefabricated bridge when in use, should be erected at both ends of bridge load rating, mark card, to prevent overload operation, and often sent to check, check the contents:
- 1, to observe all kinds of pin, bolt, beam clamp and wind pull rod is fully equipped, has no damage, there is no loose, to ensure safe passage.
- 2, check the bridge foundation there is no uniform settlement, if that should be addressed in a timely manner.
- 3, in a peripheral grease, to prevent rainwater from entering the pin hole slot, screw all bolts exposed to grease to prevent rust.
- The mid span deflection
- 4, often measuring bridge, to see whether the increased, deflection increases speed and pin and pin hole wear is this.
- 5, check the bridge panel whether rupture, deformation or have no uneven phenomenon, replace if necessary.
- The South Bailey bridge maintenance requirements:
- Steel structure fabricated steel structure, is easy to rust products, especially in the coastal regions, prefabricated bridge more easy to rust, so often on fabricated steel bridge for maintenance in order to avoid fabricated steel rust, once fabricated steel corrosion will reduce the bearing capacity and service life of bridge, so regular derusting brush the paint maintenance is a key link to guarantee the assembled steel bridge life, must not be ignored.
- The southern steel in strict accordance with the "Ministry of defense transportation reserve equipment management regulations" stipulated: all southern steel bridge three years a comprehensive maintenance.
- In order to prevent the fabricated steel corrosion, in the prefabricated bridge maintenance, engineers carefully check all parts of members have no peeling paint, rust and parts deformation etc.. The corrosion of parts, the strict requirements of workers first dirt, oil, rust and dirt to clean up, and then spray paint, paint, paint flat uniform, no leakage and blowout. If there is a component deformation, should be replaced. In order to ensure the continued safe use of prefabricated bridge.
