Abstract

An apparatus for excavating a tunnel includes a cutting wheel equipped with measuring modules of sensor means on its cutting wheel face in order to directly sample the consistency of the material present between the cutting wheel face and a tunnel face by recording different types of measured values characteristic of this.

First claim

a discharge unit ( 127 , 136 ), with which material present in the excavation chamber ( 121 ) can be removed, and
at least two measuring modules ( 151 , 154 , 157 , 160 , 163 , 503 ) arranged on the cutting wheel face ( 112 ) and configured to record measured values characteristic of the consistency of material excavated at the tunnel face ( 118 ) and in that measuring modules ( 151 , 154 , 157 , 160 , 163 , 503 ) arranged on the cutting wheel face ( 112 ) are configured to record different types of measured values for conditioning the material between the cutting wheel face ( 112 ) and the tunnel face ( 118 ) accordingly.

2. The apparatus according to claim 1 , wherein the measuring modules arranged on the cutting wheel face ( 112 ) have, in pairs, a multi-measuring module ( 151 ), a spindle measuring module ( 154 ), a ram measuring module ( 157 ), an earth pressure measuring module ( 160 ), a temperature measuring module ( 163 ), and a moisture measuring module ( 503 ), or combinations with three or more measuring modules ( 151 , 154 , 157 , 160 , 163 , 503 ).

3. The apparatus according to claim 1 , wherein the measuring modules ( 151 , 154 , 157 , 160 , 163 , 503 ) are configured to record different types of measured values for the consistency of material in the excavation chamber ( 121 ).

4. The apparatus according to claim 1 , wherein the the measuring modules are connected to an operating data acquisition module ( 169 ).

5. The apparatus according to claim 4 , wherein there is an image acquisition module ( 166 ) connected to the operating data acquisition module ( 169 ), with which image acquisition module material removed from the excavation chamber ( 121 ) can be recorded in images.

6. The apparatus according to claim 4 , wherein there is a control circuit comprising the operating data acquisition module ( 169 ), with which control circuit the consistencies of the material between the cutting wheel face ( 112 ) and the tunnel face ( 118 ), on the one hand, and in the excavation chamber ( 121 ), on the other hand, is adjustable via the conditioning elements, based on the types of measured values.

7. The apparatus according to claim 1 , wherein at least one of the measuring modules extends through the cutting wheel.

8. The apparatus according to claim 1 , wherein at least one of the measuring modules is exposed through the cutting wheel in the excavation direction.

9. The apparatus according to claim 1 , wherein at least one of the measuring modules is downstream of the excavation chamber.

10. The apparatus according to claim 1 , further comprising conditioning elements arranged between the cutting wheel face ( 112 ) and the tunnel face ( 118 ) for producing specific consistencies in the material between the cutting wheel face ( 112 ) and the tunnel face ( 118 ).

11. The apparatus according to claim 1 , further comprising conditioning elements arranged between the cutting wheel face ( 112 ) and the tunnel face ( 118 ) for producing at least two zones of different consistencies in the material between the cutting wheel face ( 112 ) and the tunnel face ( 118 ).

12. A method for excavating a tunnel comprising:
providing an apparatus comprising:
a rotatable cutting wheel ( 109 ), with which an existing geology can be excavated in an excavation direction at the front on a tunnel face ( 118 ),
excavation tools ( 115 ) arranged on a cutting wheel face ( 112 ),

an excavation chamber ( 121 ) arranged on the back of the cutting wheel face ( 112 ) in the excavation direction, into which excavation chamber material excavated at the tunnel face ( 118 ) can be conveyed,
a discharge unit ( 127 , 136 ), with which material present in the excavation chamber ( 121 ) can be removed, and
at least two measuring modules ( 151 , 154 , 157 , 160 , 163 , 503 ) arranged on the cutting wheel face ( 112 ) and configured to record measured values characteristic of the consistency of material excavated at the tunnel face ( 118 ) and in that measuring modules ( 151 , 154 , 157 , 160 , 163 , 503 ) arranged on the cutting wheel face ( 112 ) are configured to record different types of measured values,

recording of the measured values by the at least two measuring modules ( 151 , 154 , 157 , 160 , 163 , 503 ) arranged on the cutting wheel face ( 112 ), and
conditioning the material present between the cutting wheel face ( 112 ) and the tunnel face ( 118 ) based on different types of measured values.

13. The method according to claim 12 , wherein conditioning elements arranged in the region between the cutting wheel face ( 112 ) and the tunnel face ( 118 ) are configured to produce at least two zones of different consistencies through the appropriate addition of conditioning means, and in that these zones are each sampled with at least one measuring module ( 151 , 154 , 157 , 160 , 163 , 503 ).

14. The method according to claim 12 , wherein measured values are recorded by measuring modules ( 151 , 154 , 157 , 160 , 163 , 503 ) arranged in the excavation chamber ( 121 ) and in that conditioning means are added for adjusting the consistencies of the material present between the cutting wheel face ( 112 ) and the tunnel face ( 118 ), on the one hand, and in the excavation chamber ( 121 ), on the other.
