<p>A method and an apparatus are developed for continuous forming of a concrete construction (2,3,18), such as lining for a tunnel or a subpassage (2,3), or a stand-alone concrete wall (18) by means of a concrete mixture and a slip form (6) with ancillary formwork trolley (5). The slip form (6) with ancillary formwork trolley (5) is arranged for guided movement along the tunnel; and end seal (12) which is fixedly anchored to the tunnel is established; at least one concrete extruder (16) is attached to the slip form (6) with ancillary formwork trolley (5); a preferably flexible sheet (10) is arranged, which substantially covers the surface (11) of the slip form (6), so that the slip form (6) may slide in relation to the sheet (10), and where the sheet (10) is adapted for removal after hardening of the concrete (27); and the formwork trolley (5) is moved forwardly while the concrete extruder (16) is operated and fills the formwork cross section (13) by supply near the forward end (14) of the slip form (6).</p> |
