Types of Bridges Constructed by Bridge Building Companies
Bygging-Uddemann’s expertise and equipment can assist bridge building projects in several ways. We can design the slipform for bridge pylons, towers and columns, lifting systems for handling the falsework for sectional casting of the bridge span, and we can launch pre-constructed steel bridges.
Bridges are considered to be an important part of the infrastructure industry. Irrespective of the size, shape, and length, the effort that goes in while constructing a bridge is humongous.
When construction companies receive a project of building bridges, they have to consider various factors. Factors like location, usability, type of technology to be used and more. Along with that, they also have to decide and choose from various types of bridge building techniques including precast, cast-in-situ, incremental and more.
The different types of bridges that bridge building companies design are as follows.
Truss Bridge Construction
Truss bridges construction involves detailed soil analysis. The reason being, it is constructed depending on the suitability of the bridge and traffic loads. This type of bridge is ideal when a combination of multiple pressure and compression forces are going to be applied. A truss bridge typically provides a built-in support system which comprises of squares and triangular pieces which are used to balances forces and provide support to loads. This type of bridge is designed either with the road being at the truss bottom or with the road being at the truss top. Typically, the types of truss bridges include:
- Howe Truss
- Lenticular Truss
Beam Bridge Construction
When there is a need to create a construction to cover a road, water body or even a valley, beam bridge construction is used. This is known to be the most common type of bridge building. Its is used for shot spanning distances and perfect to carry light loads. Beam bridges can be as simple as they can get and make of even wood beams. Besides wood beams, these bridges are also fabricated of concrete beams. This bridge type consists of a beam that is laid across the piers and support which handle the pressure put on it.
Cantilever Bridge Construction
Cantilever bridge construction involves this type of bridge having support on one or both ends. The basic aim of this type of bridge is to attach the segments in an alternate manner at opposite ends of cantilevers supported by piers. Bridge launching is easily adaptable due to this type of bridge especially for irregular and long span lengths, congested project sites, rough and water terrain, rail crossings, and environmentally sensitive areas. Cantilever bridges are quite rigid in nature because of which they are able to carry heavy loads without the fear of breaking down.
Cable Bridge Construction
Cable bridge construction is the most common type of bridge option when it comes to bridge building. This type can be built either using concrete or steel, but more often than not, the combination of both these materials is used. Since the construction of this bridge is sturdy, it is strong enough to hold horizontal platforms which acts as the main surface for construction. Many of the famous bridges in the world are built using this type.
