Definitions
- the invention relates to devices for driving sections, tunnels or the like of the type corresponding to the preamble of claims 1 or 2.
- Such devices are known for example from DE 195 34 814 AI and are generally referred to as "tunnel boring machines”. They have a shield arrangement that protects the machine area against a radial collapse or collapse of rock or soil up to the start of the rock protection, which is indicated, for example, by a
- these tunnel boring machines comprise a working head which can be driven in rotation and which serves to loosen the soil material present at the face.
- a working head which can be driven in rotation and which serves to loosen the soil material present at the face.
- it carries, on its side facing the working face, distributed first cutting rollers distributed within the outer circumference of its front surface and radially projecting second cutting rollers over its outer circumference, also called “caliber cutting rollers”.
- the latter serve to advance an overlap which extends over the outer circumference of the working head and is required to advance the shield arrangement in the bore.
- the radial protrusion of the caliber cutting rollers over the outer circumference of the working head, which at least in size and regularly also otherwise otherwise correspond to the first cutting rollers, is accomplished with the aid of holding devices which extend almost to the outer periphery of the shield arrangement, each of which has at least one caliber cutting roller in one with its cutting edge Take up the position inclined towards the bore wall - up to an angle of 90 ° to the direction of advance.
- a holding device which allows the respective cutting rollers to be assembled or disassembled from the side of the working head facing away from the face of the tunnel bore is known, for example, from EP 0 072 503 B1.
- this holding device extends almost to the outer circumference of the shield arrangement, the latter is at a minimum distance from the face of the holding device, depending on the dimensions of the holding device, in which the tunnel wall is unprotected from radial collapse or collapse of rock or soil. Furthermore, because the risk of the bore wall collapsing in the unprotected area increases disproportionately with increasing distance between the end of the shield arrangement and the face, there is an effort to keep this area as small as possible.
- the second cutting rollers - the so-called caliber cutting rollers - have a larger outer diameter than the first cutting rollers.
- the holding devices of the caliber cutting rollers can be dimensioned to project less radially beyond the outer circumference of the working head, so that - in extreme cases - the shield arrangement with its front edge almost up to the
- Cutting the caliber cutting rolls can be relocated. Since the size of the caliber cutting rollers increases their inclination with respect to the direction of advance toward the outside while achieving the same overcut radius, the radius of curvature of the edge area of the face can also be increased, whereby the shield arrangement can be moved closer to the face face and thus the length of the unprotected area the tunnel wall is reduced again.
- the brackets for the second cutting rollers means which allow them to be optionally mounted in different positions projecting radially beyond the outer circumference of the working head, without the entire bracket being extended further from the outer circumference of the working head.
- This measure enables the end of the shield arrangement facing the working head to be moved closer to the working face compared to conventional tunnel boring machines.
- the lateral surface delimiting the outer circumference of the working head and its end face are therefore preferably provided with a high-strength wear plate.
- the interchangeability of the second cutting rollers is considerably simplified if they can be assembled and disassembled from the side of the working head facing away from the working face.
- second cutting rollers of different outside diameters which can be optionally mounted on the working head. This measure allows the size of the overcut to be adapted to the respective conditions in a simple manner by using second cutting rollers of suitable diameter. This is particularly advantageous if the bore to be driven extends to changing rock types that collapse to different extents in the unprotected area.
- the first and / or the second cutting rollers are usually designed as cutting disks having a radial cutting edge.
- the working head is intended for drilling into hard rock, it may be advisable to use one or more of the cutting disks - both the first and the second cutting rollers - as so-called
- wart disks that have at least one radial extension protruding from the circumference on their cutting edge.
- the shield arrangement has a recess extending from its edge facing the working face, since this measure makes those second cutting rollers located in the region of the recess more accessible.
- the shield arrangement In order to avoid that wall material that collapses from above or overburden that accumulates at the bottom of the tunnel can penetrate the recess, it extends over the smallest possible angular range, preferably about 10 °, and is below the center of the tunnel cross-section, preferably the highest Place of the shield arrangement cross-section, as seen approximately in the angular range from 130 to 140 ° - ie in a "four o'clock or eight o'clock position".
