Layout modification project of the DN 1,200 mm pipe in the area of the Sagrera station – Barcelona
– The projected work consists of the modification of the 440 m section of the Ø 1,200 elevation 70 main of Barcelona which runs, inside a gallery, under the track yard of the Sagrera railway station.
– As the redevelopment of this railway facility is necessary for the new High-Speed Train station, the installation of the new main, 560 m long, in steel and Ø1,200, is planned under the surface of the tracks of Avenida de Santa Coloma and Calle Ciudad de la Asunción. The crossing over the track yard was carried out by means of a 77.2 m metal bridge, with two similar spans and a box structure 1.9 m high and 3.0 m wide, which will be attached to the existing road bridge.
