RELIABLE FOUNDATIONS FOR RAILWAY BRIDGES WITH DRILLED STEEL PIPE PILES

Railroad traffic sets specific requirements for the construction of railroad bridges. Bridges are typically constructed during short traffic interruptions on operating railroad lines. In addition to driven steel pipe piles, drilled steel piles have also been used. As an alternative to traditional drilled piles, high capacity drilled steel pipe piles based on a thick walled permanent casing tube have been developed. The main advantage of the pile type is reliability in technical, economic and schedule terms.
