Definitions

  • the invention relates to tunneling machines for mechanically opening tunnels and sections using the full-cut method, consisting of a machine frame that can be braced in the tunnel or in the section and is gradually moved forward on which the drilling head equipped with tools is rotatably mounted and can be moved relative to the machine frame by a feed path against the face .
  • a practiced solution to the problem consists in excavating large tunnel cross sections in two stages in order to avoid geological difficulties.
  • H First, create a pilot tube from which the surrounding mountains can be consolidated if necessary. This pilot tube is then expanded to the final tunnel diameter in a second pass.
  • Such a method is very time-consuming and costly.
  • the present invention has for its object to provide a tunneling machine of the type described above, with which it is possible to dig large tunnel or route cross sections in one step, even in geologically difficult, for. B. fragile and brittle mountains.
  • the invention proposes that the rotary plane of the drill head is inclined in the direction of advance, the axis of rotation of the drill head making an angle between 20 and 50, preferably 30 and 45 * , in a vertical plane with the longitudinal axis of the tunnel or line.
  • the entire area of the drill head is also conceivable to secure the entire area of the drill head with a full shield.
  • the drives for the drill head are preferably arranged closely behind the drill head, axially parallel to the drill head axis.
  • the proposal of the invention inevitably creates a tunnel or route cross-section which is elliptical in projection, such a cross-section is often desired, especially in the case of large tunnel cross-sections.
  • the opening of traffic tunnels is made easier with a tunnel boring machine of the type proposed here, because two adjacent traffic arteries are generally provided there, that is to say a greater width than the height of the tunnel is to be aimed for.
  • FIG. 1 An embodiment of the invention is shown in the drawing and is described below. It shows a tunneling machine in a shield.
  • the machine essentially consists of the drilling head (2) equipped with tools (1), the gear housing (3) with the drive units (4).
  • the machine frame (5) is pressed with the drill head over the feed cylinder (6).
  • a bracing unit (7) serves as an abutment.
  • the machine can also be supported on the segments by hydraulic cylinders (9).
  • the area up to the face can be secured by a sign (10).
  • This shield (10) can be a rigid full shield. It can also be single shields, e.g. B. be pressed hydraulically.
