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

(57) A summary foundation element includes an upright prefabricated frame (10), A frame includes the cross member (14) who connects at least two the accommodation side wall (12) and two side walls (12) which counter, and forms the penetration cavity for 鋳込みs between these two side walls (12). A frame (10) is held on the ground (G) through good regulation support equipment (22), And it enables it to accept the hardenability liquefied binder material (36) poured in through the penetration cavity. It can leak and come out through between the ground and side walls (12) on the ground (G), and this binder material fills a cavity, wraps a cross member (14) and an iron rod (34), or other connection components, and enables connection with a superstructure element (32). This structure has the foundation element made by the above-mentioned prefab frame (10) about the prefabricated frame structure object in which the present invention includes a prefab tunnel again.
