This includes her drill head cutting rollers by loosening the soil a pilot hole on the route profile on the face expand. Generating an overcut by loosening is of earth on the stretch wall with this tunneling machine not possible.
  • the invention provides that when working out the overlap is worked according to the undercut principle. This has so far been used to create an overcut existing problems significantly reduced or eliminated and favorable conditions for the execution of the process as well as the stress on the elements involved.
  • Undercutting is an effective working principle in which mainly only that compared to the compressive strength low tensile strength of the rock can be overcome got to. It is also important that an overcut or another Profile enlargement without conversion work on the drill head, for example Charging devices in this particularly advantageous manner is made possible.
  • the method can still be carried out so that the Working head during the generation of the overcut one Rotation without movement is given in the direction of advance. This can include then come into consideration if only on certain A profile enlargement can be generated should, with the working head separated from the working face can be or also attacks on this.

  • the working head 1 is normally used for working out of a circular cross-section and is for this purpose with center tools 11, with over its end face distributed roller drilling tools 12 and with caliber tools 13 provided. To pick up the loosened pile or small rocks, the working head 1 has a rotating one Loading buckets 14 or the like. on. With the letter U is the outer working contour determined by the caliber tools 13 of the drill head 1, which is equal to Circular contour of the traveled route on the face is (see also Figures 3 to 5). The diameter of this Circular cross section is shown in Figure 2 at the letter D.
  • the working head 1 is on two Places offset by 180 ° with tools 15 provided that retracted from a radially inward Rest position brought into a radially outer working position in which they are intended to attack the mountains Areas of a selectable amount over the working contour U protrude from the drill head. Acting with these tools are undercut cutting rollers or disc rolls.
  • the lower tool 15 in FIG. 2 stands in its radially inner resting position while the upper one Tool 15 assumed a radially outer working position Has.
  • the movement of both tools 15 is like this controlled that it is a dot-dash line designated K1 Work out the indicated contour, the so-called overlap results.
  • the contour K1 falls at the lowest point of the working head 1 with the lowest point of the working face or the working contour U of the drill head together while a difference E1 at the highest point between the two consists. This is the maximum overcut amount.
  • the Control of the movements of the two tools 15 happens continuously in the course of a drill head revolution so that the contour K1 results.
  • the size of the overcut is expediently selectable or adjustable.
  • 2 shows a second overcut contour as an example K2 drawn, with a larger Difference E2 compared to the circular contour U results, for example twice the overcut amount E1 is.
  • Figures 3 to 5 illustrate some statements for the design and arrangement of a profile enlargement tool, each in the form of a holder stored, undercut working disc roll 15.
  • the working head 1 is only largely schematically with its supporting structure 16 and without his tools 11, 12, 13 working the face B. ( Figure 2) reproduced.
  • the cutting rollers 15 are in the Figures 3 to 5 each in a normal working contour U of the drill head 1 moved out position shown.
  • FIG. 3 is a holder 21 for the Cutting roller 15 designed as a double piston 22a, 22b, which is radially displaceable in a cylinder 23. If the upper cylinder chamber 23a If a pressure medium is supplied, the piston moves 22a, 22b with the holder 21 and the cutting roller radially outwards into the position shown. In doing so, the rotation of the working head 1 and a feed movement worked out a profile enlargement, approximately an overlap according to FIG. 2 with the contour K1. In FIG. 3 is illustrated by the dash-dotted contour line, that the cutting roller 15 in the course of a Feed movement of the working head 1 from its retracted Rest position gradually except for the one shown the position corresponding to the contour K1 can be pushed out can. The insertion of the holder 21 with the cutting roller 15 is done by draining the pressure medium from the Cylinder chamber 23a via line 24 and supply of Pressure medium to the cylinder space 23b through the line 25, through which the pressure medium flows in the reverse process could.
