<p>The present document shows a culvert system for laying of social infrastructure below ground level. The culvert system comprises a channel module (10, 10a, 10b, 10c), which defines an elongate space for laying of a plurality of conduits (31, 32, 33, 34, 35, 36) so that these extend in the longitudinal direction of the channel module, and a coupling chamber (20, 20', 20"), which defines a coupling space for joining of and/or connection to/from said conduits. A [ratio] between a density of the coupling chamber (20, 20', 20") and a density of the channel module (10, 10a, 10b, 10c) is greater than 1, preferably greater than 10, or greater than 100.</p> |
