Abstract (en)

[origin: WO9603552A1] An underground passage including footings (3) supporting prefabricated elements (5) such as shell halves for erecting an arch, said elements (5) being joined together at the keystone by means of a cast concrete tie beam. The length of the projections (11) integral with the elements (5) is such that the ends of said projections (11) are far enough apart in the assembled position to avoid ever touching one another when the shape of the shell halves (5) is changed during backfilling.
