What measures are needed for the maintenance of Bailey panels?

Bailey panelDetection of Bailey panels is crucial for the safety of the project. When inspecting the Bailey panels, it is necessary to check not only the panels themselves but also the testing frame. The testing frame is used to test the stiffness and strength of the Bailey panels, so it is required that the stiffness and strength of the testing frame can meet the measurement requirements when the Bailey panels bear external loads exceeding the yield stress.

Therefore, it is necessary to determine the ultimate load of the testing frame. Under a pressure of 750 kN, both the strength and stiffness of the testing frame can meet engineering requirements. To determine the ultimate load of the testing frame, the approximate principle can be used to gradually increase the external load until its strength approaches the yield limit.

1. ObservationBailey panelCheck whether various pins, bolts, beam clamps, and wind-resistant tie rods are assembled completely, and whether there is any human damage or looseness to ensure safe passage.

2. Periodically check whether the Bailey steel bridge's infrastructure has any uneven settlement, and if found, it should be dealt with in a timely manner.

3. Apply grease around the pins to prevent rainwater from entering the holes, and grease all exposed threads; all exposed threads of bolts should also be greased to prevent rust.

4. Be sure to measure the mid-span deflection of the bridge to see if it increases. The rate of increase in deflection should be consistent with the wear of the pins and pin holes.

5. Check whether the bridge deck has cracks, deformations, or unevenness; if necessary, it should be replaced.

6. During maintenance, engineers should carefully inspect each component of the steel bridge to ensure that there is no paint peeling, rust, or deformation.

For rusty components, workers are required to strictly clean dust, grease, rust spots, and various dirt, then spray paint evenly, ensuring a smooth paint surface without leaks. If there are deformed components, they should be completely replaced to ensure the continued safe use of the steel bridge.

The above is what I shared with everyone regarding the detection methods for Bailey panels. I hope that after reading it, you can have a further understanding of it.
