    摘要： A tunnel reinforcement system having a plurality of structural supports positioned at spaced intervals along the length of a tunnel. Each structural support has a plurality of structural segments connected in an end to end relationship. Each structural segment has a plurality of bars connected to a first end and a second end, in which the first end comprises a first butt plate having one or more apertures, and the second end comprises a second butt plate having one or more apertures. The one or more apertures of the first butt plate or the second butt plate of a structural segment are coaxially aligned with the one or more apertures of the first butt plate or the second butt plate of another structural segment in an end to end relationship. The first butt plate or the second butt plate of a structural segment is attachable to the first butt plate or the second butt plate of another structural segment in an end to end relationship. Each structural support defines a geometric supporting framework.

    摘要： The invention relates to a tunnel lining segment of reinforced concrete, wherein the tunnel lining segment has a load transfer area for a longitudinal joint, with at least one steel bar with an end face being installed in the tunnel lining segment, the steel bar being arranged in the tunnel lining segment in such a way that a tangent to a centroidal axis of the steel bar encloses an angle of between 0° and 45° in the end face with a normal to the load transfer area, and wherein the end face is arranged at a distance (a) from the load transfer area which is between 0 mm and 50 mm, preferably between 0 mm and 10 mm.

    摘要： Described herein are apparatus, systems and methods useful in forming underground vertical structures. Methods are described for constructing an underground vertical structure, comprising the steps of excavating soil to a sufficient depth to create a circular void to accommodate a plurality of segments; assembling a ring shaped structure comprising the plurality of segments; connecting the outside surface of the ring shaped structure with the soil in said circular void, thereby securing the ring shaped structure to the soil; excavating earth beneath the ring shaped structure to accommodate a second ring shaped structure; and repeating steps b-d thereby forming one or more additional ring shaped structures downward into the earth below already formed ring shaped structures until a predetermined depth is reached; thereby forming the underground vertical structure. Systems to perform the above methods are also disclosed.

    摘要： A tubbing lining for a tunnel or shaft is formed from tubbing rings having annular end surfaces, with successively tubbing rings are aligned with each other at annular end surfaces forming an annular joint. Each tubbing ring is composed of successive circumferentially arranged tubbing segments which are butt-joined. A deformable flexible element having an outer cross-sectional contour is arranged in at least one butt joint, with the cross-sectional contour parallel to the butt joint matching outer contours of the end faces such that the flexible element completely covers at least one abutting end face. The tubbing segments in conjunction with the flexible element form a prefabricated element formed of a steel reinforcing framework encased in concrete to which the flexible element is connected in a force-locked manner.
