Drum tubes

The Wizard system’s Drum Tubes target category belongs under the Equipment dataset of the Equipment Register. The target class of drum tubes was in the road register as TL 509 drum tubes. Drum pipes are drainage structures designed to lead surface waters of open ditches and waterways under a road, street, bridge or water embankment. All drums with a diameter of less than 2 000 mm are counted as drums. Larger than this are bridge drums and are not controlled by the wizard. If there are two drums (double drums) next to each other, both are their own object in the Wizard. Tievelho manages the structural and functional characteristics of drums, as well as related fitness, operation and administrative data. The descriptions of the characteristics of the wizard’s data can be found here: https://ohje.velho.vaylapilvi.fi/tietokuvaus/#Ominaisuustietokuvaukset The data covers the road network maintained by the Finnish Transport Infrastructure Agency.
