Specialized tools called bearing sleeve are vital components involved in the structural safety and integrity of a bridge. You could visualize them like stretched pillows so that the bridge can bend and sway without breaking. The more you know about bridge bearings, the more you will appreciate the functionality of bridges, and the reasoning behind construction.
Bridge bearings primarily serve to carry the entire weight of the bridge and any vehicles passing over it (cars, trucks, bus, etc.). They allow the deck of the bridge to move like butter. This is very vital when the temperature is changing, since that will cause the components of the bridge to expand or shrink. It also perplexes when a heavy load is placed on the bridge, such as when many cars are on it together! The bridge could suffer damage over time if the brige bearings done not do their job properly.
Pot bearings: These unique bearings need to support heavy loads as well and hold the other end of the bridge in place. They have a circular, bowl-like base and a top that slides smoothly — like a bug in a carpet — into the bowl. This design is what prevents the bridge from falling over.
Spherical Bearings: These bearings are used when the bridge is built in a curve. They are aimed to continue the movement in the multiple directions which is imperative in the design of the curved bridges. Such versatility is making the bridge respond to various forces including winds and traffic.
Bridge bearings are not different from any other part of a bridge, requiring periodic inspection and care. This is extremely critical to ensure they are functioning properly to keep travelers safe crossing over the bridge. Improper maintenance of bearings can amplify damage or result in bearing failure, jeopardizing the bridge.
All the elements of the bearings are scrutinized by the engineers during maintenance. They inspect the base, ensuring sufficient lubrication, and observe wear or deformation. They also look for signs of rust that can deteriorate the materials. It is important to repair it because regular maintenance identifies any problems in their initial stages which saves a big amount of time, effort and money in the long run.
The best bearing sleeve types are especially important to keeping the bridge in a state of safety and strength. The image above shows the assembly field so that bridge must support the bearings well; but if the bearings are not good, they may not be supported. Improper bearings selection can easily result in serious issues, including a bridge becoming unstable or even collapsing.
