Railway Bridge, Zurich, Switzerland
Uninterrupted Rail Traffic during Construction
Automatically Moving Formwork Carriage for Composite Bridge
The new 187 m long composite bridge spanning the Zurich main station area replaced a more than 100 year old, two lane steel arched bridge. Thanks to the fanned arrangement of the tracks below, no obstructions were encountered during construction. With the new bridge, the number of trains arriving and leaving the station will be increased.
The steel composite construction consists of three launched box-type steel girders (each 2 m high) and a concrete slab. The client, Swiss National Railways (SBB), requested a formwork solution, which guaranteed an uninterrupted flow of normal rail traffic during the concreting of the slab.
Very soon after receiving the order, PERI delivered an efficient formwork carriage construction, which was designed for casting 10 m long cycles. Without the help of additional lifting equipment, the carriage was moved from cycle to cycle using an electric motor and rollers.
Less than five hours were needed for lowering, moving and positioning the carriage.
