Understanding the Application of Bailey Bridge Panels

The Bailey beam support is a type of material characterized by its simple structure, convenient transportation, quick assembly, large load capacity, good interchangeability, and strong adaptability. What is the application of the Bailey beam support? Let's find out.

Bailey beam supports can be used for highway bridges, assembled gantry cranes, guide beams, bridge erecting machines, and hanging baskets, etc. They use prefabricated components of highway steel bridges to assemble the gantry frame, and their span and column height can be adjusted to adapt to different work sites, widely used in highway, railway, municipal, construction, and water conservancy projects, lifting and transporting prefabricated components at bridge construction prefabrication yards, and on-site construction operations such as transporting large beams beside piers.

When using the Bailey beam support, signs indicating the load rating should be erected at both ends of the bridge to prevent overload operation, and regular inspections should be conducted. What are the inspection contents for the Bailey beam support? Let's take a look.

1. Observe whether all pins, bolts, crossbeam clamps, and anti-wind tie rods of the Bailey beam support are fully assembled, whether there is any human damage, and whether there is any looseness to ensure safe passage.

2. Regularly check whether the foundation of the Bailey beam support bridge has uneven settlement, and if found, it should be dealt with promptly.

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

4. Always measure the mid-span deflection of the bridge to see if it increases; the rate of deflection increase should equal 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.

According to the actual needs of different spans, Bailey beam supports can be composed of various types of temporary bridges, emergency bridges, and fixed bridges. Bailey beam supports are characterized by fewer components, lightweight, and low cost. Because of these features, Bailey beams have been widely used. Today, let's first discuss the precautions before operating the Bailey beam. This is a very important task that should not be overlooked.

1. Incomplete inspection content, issues found during inspections are not rectified properly, repeated mistakes without truly understanding what safety is and the consequences of ignoring safety, and not taking major issues seriously.

2. The special plan for key process points is not well-prepared, the briefing is superficial, the work guidance is not detailed, training is inadequate, and on-site technical management is weak.

3. Work style is not solid, on-site inspections are superficial, issues found are not addressed in a timely manner, management personnel do not control on-site construction effectively, inspection depth is insufficient, responsibility is weak, and there is a lack of awareness of existing problems and safety hazards on-site.

4. On-site worker training is inadequate, management is lacking, workers have strong randomness in on-site construction, there are no constraints, they do as they please, and how to handle incidents after they occur is not executed according to regulations, which is key to the subsequent social impact.
