The distribution shaft (S) is designed so that the shaft wall (W) is composed of shaft wall modules (M1-M10) jointed to each other, with butt joints (F) separating the respective line openings (0) around the lines (T1,T3), laid fixed to the junction point (A). The shaft wall (W) is composed of several round or square rings (E,EE1-E3) with ring axes lying in the shaft axis (X). Each line opening (0) is separated by the butt joints (F) between two of the rings. |
