Method of constructing a tunnel lined with a tubing element
An articulated drilling tool (7) and a draw cable (6) is brought from ditch (3) to ditch and the tunnel opening (9) to be lined is formed in the ground (2) between the ditches. In one ditch a rotating tunnel boring machine (12) is fixed to the draw cable and with the aid of a tractive machine (20) in another ditch the tunnel boring machine is drawn from the first to the second ditch. At least three ditches are made and the draw cable is fed from one ditch over a second to a third. The ditch in which the tractive machine (20) is located, at least on the sides where a tunnel (1) is to be formed, is clad with a wall (4), which is interrupted at the position of the mouth of the tunnel and on it the tractive machine during drawing is supported.
