What Do We Need To Pay Attention To When Maintaining The Steel Bridge

1. Check whether the bridge panel is damaged, defective and deformed, and replace it when necessary.
2. Observe whether the various dowels, bolts, beam fixtures and wind tension rods of Beret pieces are assembled, whether there is artificial damage or loosening to ensure stable passage.

3. Check whether the bridge panel is cracked, deformed or uneven, and it should be replaced when needed.

4. Measure the mid-span deflection of the bridge to see if it will increase, and the speed of the increase in deflection should be the same as the wear of the pins and pin holes.

5. Check whether the Beret steel bridge foundation has uneven settlement, and adjust it in time if found.

6. Grease around the pin to prevent rain from entering the gap in the pin hole, and grease all the exposed threads of bolts to prevent rust. Beret chips are widely used in traffic engineering. Beret plate has the characteristics of simple structure, convenient transportation, large load capacity, good interchangeability and strong adaptability.

7. In the maintenance, the engineer should carefully check the various components of the steel bridge, and there is no paint falling off, rust and deformation in each part. For the rust parts, the workers are strictly required to clean up the dust, oil, rust and various dirty things first, and then spray paint, paint evenly and paint flat. If parts are found to be deformed, they will be replaced to continue the stable use of the steel bridge.
