Abstract

The subject of this invention is a method and means for making a tunnel comprising preventive consolidation prior to excavation, in the form of a facing 10 obtained in an associated slot 1 pre-cut from the demolition face 11. The method comprises the tight application in the orifice 4 of natural formwork formed by the opposing surfaces 12, 13 of the slot 1 and by its bottom, of successive pairs of pneumatic plugging elements 2, by means of their inflation in contact with the top free end of the elements 2 of the previously installed pair, starting from the bottom end of the orifice 4. The application of each pair of elements 2 follows the deposit of a casting of a cement mixture 6 until the facing vault 10 is obtained. When the casting has set, the pair of elements 2 are disengaged by deflation, starting from their first bottom pair, and then the tunnel inside the facing vault obtained in this way is excavated to a shorter depth than the depth of the vault itself.
