Artworks by type

Evolution per year of the number of civil engineering structures managed by Infrabel, by type and area since 2012.Civil engineering structures : Civil engineering structures belonging to the domain of civil engineering (bridge, retaining wall or protective structure) necessary for the construction of tracks and their bedding or made necessary by their constructionType of civil engineering structures and description :UnderbridgeCivil construction with an opening greater than or equal to 2 m provided for the crossing of one or more railway lines and for which the crossing traffic is at a lower level than the railway line.OverbridgeCivil construction intended for vehicular or rail traffic with a length less than 100 m and for which the crossing traffic is at a higher level than the railway line.Passage under tracksUnderbridge exclusively reserved for non-motorised users.FootbridgeConstruction exclusively reserved for non-motorised users.CulvertSmall structure whose opening is greater than or equal to 60 cm and less than 2 m.PassageSmall structure whose opening is greater than or equal to 30 cm and less than 60 cm.TunnelBridge whose length is greater than or equal to 100 m.Retaining wallWall, screen or wall with a supporting function, i.e. the ground level is different on both sides of the wall. Anchored slopes also belong to this type.Rock wallGeological formation whose nature allows a much steeper slope than a normal slope in open ground. Therefore, the rock wall is prone to subsidence with the risk of falling stones on the railway platform. A rock wall may or may not be reinforced. It is referred to as a reinforced rock face if works have been carried out to ensure the stability of the rock face.Noise wallWall, screen or wall along the railway tracks that only has an acoustic function to reduce noise pollution due to train traffic.Buffer basinAvailable volume to store water with the aim of avoiding flooding of the protected infrastructure in case of storm or flood.
