Abstract
A method of lining a tunnel comprises providing a plurality of injectors (7) on an apparatus, the injectors being positioned adjacent an internal tunnel surface (6) or (41) and using the injectors to place and compress and, if required, crush the solid particles of, and dewater the lining material (5) to form a structural tunnel lining. The apparatus is moved forward by the pressure exerted by the injectors (7) as they discharge the lining material. Articulated shuttering for the tunnel lining is provided on a trailing side of the apparatus. The injectors (7) can be arranged on an apparatus having a cross-section corresponding to a cross-section of a tunnel to be lined.
Claims18
A method of lining a tunnel, comprising providing a plurality of injectors on an apparatus, the injectors being positioned adjacent an internal tunnel surface facing away from the direction of travel parallel to, or at an angle to, a centreline of the tunnel, using the injectors to place, and compress tunnel lining material to form a structural tunnel lining, and moving the apparatus forwards by the pressure exerted by the injectors as the tunnel lining material is discharged, articulated shuttering for the tunnel lining being provided on a trailing side of the apparatus.
An apparatus for lining a tunnel, comprising a plurality of injectors for placing and compressing lining material on an internal tunnel surface, to form a structural tunnel lining, and for moving the apparatus forwards by the pressure exerted by the injectors as the lining material is discharged, the injectors being oriented with respect to the apparatus to face away from the direction of travel parallel to, or at an angle to, a centreline of the tunnel, and articulated shuttering for the tunnel lining, provided on a trailing side of the apparatus, the shuttering comprising mutually articulated rings of plates, and rods extending through apertures in the rings to constrain the degree of relative displacement of the rings.
