Pot Bridge Bearing construction

Construction Process: Preparations Before Pot Beam Installation

Before installing the pot beam, check it. Make sure it is intact and meets design requirements.

At the same time, we must check its foundation to ensure that it is flat, solid, and free from debris and ponding. Before installing, calibrate the position. This ensures accurate installation.

Pot Bridge Bearing construction

Pot beam installation

1. Draw the centerline at the design position of the pot beam, and mark the centerline on the top and bottom plates.

2. Thread the anchor bolt into the anchor bolt hole of the base plate (top plate) and screw it into the bottom column. Place a rubber washer between the base plate and the bottom column. The washer’s diameter should be a bit larger than the bottom column.

3. After placing the pot beam, pour epoxy mortar or high-grade mortar into the anchor bolt hole. Also, fill the base plate cushion. Make sure to center and level it. Take out the cushion block once the mortar is hard. Then, fill the space with epoxy mortar. The workers must pour the epoxy mortar in a thick layer.

4. When welding connects pot-bearing, embed steel plates in the top and bottom plates. Then, use symmetric intermittent square welding after they are in place. During welding, be careful. Too much heat can damage the rubber plate and the polytetrafluoroethylene plate. The team must carry out rust release treatment on the welded parts after welding.

5. If the T-beam is a pot type, construction workers need to install support measures at the beam end. This will stop the T-beam from tilting. Remove the temporary support after welding the transverse diaphragms to the two T-beams.

6. After unpacking, protect the PTFE plate and stainless steel sliding plate. Keep them free from scratches and dirt. Also, check if someone has filled the 5201-2 silicone grease.

7. The pot beam centerline must coincide with or be parallel to the main beam centerline. When installing the pot beam, keep the upper and lower guide blocks parallel. The intersection angle should not exceed 5°. For continuous beam bridges, take thermal insulation steps. This helps protect rubber and polytetrafluoroethylene plates. Do this when using temporary anchorage devices for system changes and cutting.

Pot beam change

After installation, adjust the pot beam. This helps ensure it can handle its load and deformation as required by the design. Use professional tools to measure deformation and bearing capacity during the change. In case of deviation, someone must adjust it on time to ensure its stability and safety.

Technical Points and Precautions:

• Adhere to design requirements during construction.

• This ensures quality and safety.

Someone will watch and manage each step in the construction process. This helps prevent quality issues and safety hazards. Use professional lifting equipment when installing the pot beam. This ensures the installation position is accurate and stable. During installation, pay attention to its levelness and verticality to avoid deviation. Use professional measuring tools to check the point beam’s deformation and bearing capacity. In case of deviation, someone must adjust it timely to ensure its stability and safety. During construction, we must focus on protecting the environment. We should also ensure civilized practices on the site. After they finish construction, they need to clean up the site on time. This will help make sure the area looks neat and nice.

Post-construction acceptance and maintenance

After construction, the team must accept the pot beam. This step confirms it meets design and quality standards. During acceptance, you must inspect its bearing capacity, deformation, and connections. This ensures stable, safe, and reliable performance. After acceptance, conduct regular maintenance on the pot beam. This helps maintain its long-term operation without issues. During maintenance, inspect the connection parts and rubber materials. Identify and resolve any problems without delay. This helps ensure safety and extends service life.
