Definitions
- the invention relates to a tunnel boring machine according to the preamble of claim 1.
- Such a tunnel boring machine is known from CN 107 607 082 A.
- This known tunnel boring machine has a shield jacket extending in a longitudinal direction and a sensor unit equipped with distance sensors for detecting convergences.
- the distance sensors work to carry out a continuous measuring process with a continuous spring force and are in constant contact with the pending rock during the advance.
- a sensor unit in the form of a hydraulic cylinder is provided, which is installed near the cutting wheel in the ridge area on the shield jacket. With this hydraulic cylinder, the thickness of the annular gap at the tunnel crown can be measured in order to detect convergences. From CN 207879337 U a tunnel boring machine with a shield jacket extending in a longitudinal direction and with a sensor unit having a number of laser rangefinders, which are in the longitudinal direction and in
- the invention is based on the object of specifying a tunnel boring machine of the type mentioned at the beginning, which is characterized by a reliable measurement of an annular gap present between the shield jacket and the rock.
- this object is achieved according to the invention with the characterizing features of claim 1.
- the location accuracy in the position of the distance sensors is very reliable and easy to measure, and it also ensures that the distance sensors are not damaged in the extremely harsh environment during the driving phases.
- the sensor unit in the tunnel boring machine has at least two, expediently more than two, hydraulic distance sensors with an extendable probe head with extension path measurement, which are arranged in the longitudinal direction at at least one measuring distance and with more than two distance sensors expediently also in the circumferential direction, As the advance progresses, convergences in the area of the shield jacket can be determined in changing distance values and evaluated by means of the central unit. Further expedient refinements of the invention are the subject matter of the subclaims.
- FIG. 1 in a side view
- Fig. 3 shows in a block diagram an exemplary embodiment of a sensor unit and a central unit with others
- FIGS. 4 to 7 show a further sectional views
- FIG. 1 shows a sectional side view of an embodiment of a tunnel boring machine for driving a tunnel in a rock 103 in the area of a shield jacket 106.
- a number of feed presses 109 are attached to the shield jacket 106, which act in a longitudinal direction of the shield jacket 106 and are driven in advance on tubbings 112 of a ring structure for lining a tunnel.
- tubbings 112 On the front end face of the tubbings 112 opposite in the direction of advance
- a cutting wheel not shown in FIG. 1, with which a tunnel cavity can be introduced into the rock 103.
- the tunnel cavity created by the degradation effect of the cutting wheel has a larger diameter than the diameter of the shield jacket 106, so that an annular gap 115 is formed between the rock 103 and the outside of the shield jacket 106.
- the annular gap 115 is usually at least partially filled with liquid and solid, granular components from the mining operation.
- convergences of the mountain range 103 usually lead to the annular gap 115 tapering in the longitudinal direction of the shield jacket 106 pointing away from the cutting wheel in the direction of the segments 112. If the convergence is too great and the rock 103 comes into contact with the shield jacket 106, there is therefore the risk that the
- Tunnel boring machine is jammed.
- each distance sensor 121 has a probe head 124 which enters the annular gap 115 in the radial direction can be advanced and is set up as a distance value within the scope of an extension path measurement for measuring the distance between the shield jacket 106 in the area of the relevant distance sensor 121 and the mountain 103.
- FIG. 2 shows, in a cross section in the exemplary embodiment according to FIG. 1, the shield jacket 106 in the ridge area. From FIG. 2 it can be seen that, in addition to distance sensors 121 arranged at a measuring distance in the longitudinal direction of the shield jacket 106, the sensor unit 118 also has distance sensors 121 that are arranged along the circumference of the shield jacket 106. In the arrangement according to FIG. 2, the distance sensors 121 arranged along the circumference of the shield jacket 106 are positioned essentially symmetrically to a central vertical axis 203. The angle of the distance sensors 121 to the central vertical axis 203 is expediently between approximately 15 degrees and approximately 45 degrees, preferably in the range of approximately 30 degrees.
- distance sensors 121 are also arranged in the middle of the ridge area on the central vertical axis 203.
- FIG. 3 shows, in a block diagram, the sensor unit 118 with the distance sensors 121, which are connected to a measurement data memory 303 for storing the distance values obtained via the distance sensors 121.
- a timer 306 and a position encoder 309 are also connected to the Measurement data memory 303.
- time data can be generated which can be linked in the measurement data memory 303 with the distance values obtained at the relevant time.
- position data of the shield jacket 106 can be generated, which can also be linked to the distance values obtained for certain positions of the shield jacket 106.
- the distance values of the various distance sensors 121 are available in a time profile and in a location profile.
- the measurement data memory 303 is connected to a central unit 312 with which the distance values with the linked time data and position data can be evaluated to the effect that convergences of the mountain range 103 can be evaluated, in particular, to determine whether certain minimum distance values between the mountain range 103 and the shield jacket 106 are observed. Furthermore, based on the temporally and spatially resolved distance values, the central unit 312 can generate a prognosis of expected convergences, especially in the area facing away from the cutting wheel and adjacent to the segments 112, in order to ensure as far as possible that the tunnel boring machine is not jammed .
- a signal transmitter 315 and a display 318 are expediently connected to the central unit 312.
- the signal transmitter 315 is set up to output a warning, for example in the form of a signal tone or an optical warning signal, when critical distance values are reached between the rock 103 and the shield jacket 106.
- the display 318 is set up to graphically display the temporal and spatial progression of the distance values recorded by the distance sensors 121 as well as of the predicted distance values.
- the central unit 312 has drive data representing the trajectory of the tunnel boring machine, which can be taken into account when evaluating the convergences with regard to critical values so that an annular gap 115 that is reduced in certain areas due to cornering does not lead to false alarms.
- FIGS. 4 to 7 show, in a sectional side view corresponding to FIG. 1, a further exemplary embodiment of a tunnel boring machine in the area of a shield jacket 106 in different phases of the advance.
- FIG. 4 shows the arrangement corresponding to FIG. 1 after the completion of a ring on segments 112 with a ring width B with retracted feed presses 109 and retracted probe heads 124 from here two distance sensors 121 in the longitudinal direction.
- the distance sensors 121 are arranged at a measuring distance D. Based on the arrangement according to FIG. 4, a propulsion cycle begins, which begins with the construction of a next
- FIG. 5 shows the arrangement according to FIG. 4 with fully extended feed presses 109 shortly before the lining of segments 112.
- the advance is interrupted so that, as shown in FIG Displacement of pieces of rock, extended and resting on the mountain 103. The to this
- Fig. 6 shows the after the shoring of the next
- FIG. 7 shows the feed presses 109 again in a maximally extended position with the probe heads 124 of the distance sensors 121 extended again to obtain distance values.
- the measurement distance D between the two distance sensors 121 here corresponds to the ring width B of the segments 112. This ensures that each measuring point on the rock 103 is detected twice or, if a number of more than two distance sensors 121 are provided, each time at a corresponding measuring distance D, the distance to the shield jacket 106 is detected several times.
- the convergences can be determined very precisely and, moreover, reliable forecasts can be generated for the region of the shield jacket 106 on the rear in the advance direction.
