A foundation element in the form of a rigid monolithic prefabricated frame which includes at least two opposite containing side walls and cross-members interconnecting the two side walls so as to form a casting through-cavity between these two walls. The frame is intended to be located on the ground with the interposition of adjustable support devices and is intended to receive a hardenable fluid binder material poured into its through-cavity and adapted to spread onto the ground between this and the side walls and to fill the cavity, encapsulating the cross-members and the iron rods or other connecting members for connecting a superstructure element. Also provided are prefabricated structures including prefabricated tunnels, with foundation elements formed by means of the said prefabricated frames.

1. A foundation element for supporting a superstructure element on substantially flat ground, said foundation element comprising a rigid, prefabricated, monolithic frame, including at least two opposite, containing side walls and cross-members interconnecting the two side walls to form a casting through-cavity between the two side walls, wherein said frame comprises a prefabricated element of reinforced conglomerate, and wherein the side walls and the cross-members are formed integrally with the side walls, said frame further comprising at least two transverse iron bars spaced from and parallel to each other and the cross-members, the ends of which bars are anchored in the side walls, said frame having adjustable support devices associated with each of the side walls for adjusting the walls at a height above the ground, whereby said monolithic frame may be placed on the ground supported on the adjustable support devices for receiving a hardenable fluid binder material in its through-cavity, whereupon binder material is able to spill out onto the ground between the ground and the side walls and to fill the cavity so as to encapsulate the cross-members and any connector members supported on and projecting from said cross-members for connection to the superstructure element, which, after hardening forms, with said monolithic frame, a monolithic mass which connects the foundation element and the superstructure element permanently to the ground.
