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 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.
