Foundation element, methods for the construction of prefabricated structures including these elements, particularly prefabricated tunnels, and prefabricated structures made by these methods

摘要

A foundation element comprises a rigid monolithic prefabricated frame (10) which includes at least two opposite containing side walls (12) and cross-members (14) interconnecting the two side walls (12) so as to form a casting through-cavity between these two walls (12). The frame (10) is intended to be located on the ground (G) with the interposition of adjustable support devices (22) and is intended to receive a hardenable fluid binder material (36) poured into its through-cavity and adapted to spread onto the ground (G) between this and the side walls (12) and to fill the cavity, encapsulating the cross-members (14) and the iron rods (34) or other connecting members for connecting a superstructure element (32). The invention also relates to prefabricated structures including prefabricated tunnels, with foundation elements formed by means of the said prefabricated frames (10).
