Substructure of elongate type intended to be laid in the ground and intended to support, among other things, an essentially vertical load, and comprising support elements 1 of concrete arranged in the longitudinal direction of the substructure, intended to cooperate in order to support a load-transmitting bed 3 intended to be loaded from above. The substructure is characterized especially by support elements in the form of beam sections 1 of concrete which are arranged at a distance from each other, seen in the transverse direction of the substructure, and elongate arch elements 2 of concrete supported by the beam sections and running between these beam sections and intended to support at least a central section of the said bed 3. <IMAGE> |
