Abstract (en)
[origin: EP2325436A2] The tubing segment is designed adjacent to a transverse gallery for on-directional drilling of drilling rods, and has an inverse cassette in which an inner panel (2) is arranged. The inner panel is arranged at stiffening sheets (3) inside a tunnel. An outer panel is provided for replacement of a tubing element. The inverse cassette is designed to be larger than the adjacent normal cassettes. The tubing segment is made of steel.
