NEW TYPE OF PREFABRICATED BRIDGE

NUEVO TIPO DE PUENTE PREFABRICADO

Details are given of a type of prefabricated bridge for spanning railway lines. Thanks to prefabrication and maximum lightness, installation is reduced to the simple in-situ excavation of the foundations and erection of the precast units. The project described consists of three semi-continuous spans (elimination of transverse joints) 7.70, 12.60 and 7.70 m respectively. The structure comprises three components: pier, box girder and deck slab. The flexibility of the system facilitates the construction of a wide variety of spans and the erection of one-, two- or three-lane structures. The erection process, equipment needed and calculation assumptions are described. /TRRL/
