- Bridge Building Techniques Used by Construction Companies
October 11, 2018
With the growth in technology, bridge construction and design has also evolved. There are new bridge building techniques being developed that make the construction of bridges a faster and more efficient process. A lot of bridge building companies and construction companies use their technology to construct durable and long-lasting structures in a timely manner.
Factors Involved in Bridge Building
There are many factors that need to be taken into consideration by construction companies when it comes to bridge building. Companies need to confirm the scale of the bridge along with the time allotted to them for the construction. They need to check the obstacles that are being crossed with the building. The local weather and nature of the soil are different environmental factors that affect the construction of a bridge. Additionally, the local cost of the materials that need to be sourced and the local labour market available for hire are also crucial factors. Last, but not the least, the site’s accessibility is vital for bridge building companies to make a bridge.
Bridge Building Techniques
There are a lot of different methods and techniques involved in constructing a bridge. The cast-in-situ technique is used to construct complex and unusual geometric shapes. It is used when there is difficulty in transporting goods. The cantilever method of construction is used to construct long-span and cable-stayed bridges. The precast technique uses precast concrete elements in building bridges. There are different methods available for the prefabrication of the concrete elements used.
The incremental launching method makes the bridge decks in sections. This is mainly used in the construction of steel girder bridges or continuous concrete bridges. Cable-stayed bridges use cables to carry the bridge deck from the tower. The arch technique is the most economical bridge building technique when it comes to constructing a bridge over inaccessible landscapes. It uses the slip forming technique for construction.
Equipment Used in Bridge Construction
Building with slip-form construction provides the quickest and most economical results. It is also a very safe method of construction. It does not require any dismantling and reassembling using heavy pieces of equipment. The slip-form method uses hydraulic jacks that allow the whole construction formwork to be raised continuously at a height.
Transportation of heavy structures like prefabricated elements that are involved in bridge building can be a costly affair for construction companies. Ensuring efficient and safe transfer of goods is a priority. A combination method of hydraulic jack and slip technology for lifting and transporting heavyweights has been a successful and economical method of conveyance.
Heavy Lifting Equipment
Controlled handling of heavy material that is used in building bridges requires trustworthy heavy lifting equipment. Rod climbers and strand climbers are relied upon at construction sites because of their adaptability when it comes to the heavy objects that need to be carried safely. They can be used to install formwork structures, complete bridge sections, and for repair work
These were some of the important bridge building techniques as well as the factors and equipment involved in the process. It is essential that bridge building companies and construction companies maintain the highest standards of safety while carrying out their bridge building techniques.
