Insbesondere betrifft die vorliegende Anmeldung Betriebseinrichtungen für die Herstellung sogenannter "Utility Tunnels", deren Innendurchmesser typischerweise im Bereich zwischen 0,2 m und 5,0 m liegt.The present application relates to an operating device for operating a tunnel boring device for introducing a tunnel into a ground, comprising

• a feed drive by means of which the tunnel boring device can be advanced in the ground,
• a tool drive, by means of which a removal tool of the tunnel boring device can be driven such that a successive removal of the soil is possible,
• at least one fluid tank for providing a drive fluid,
• at least one filtration device for the filtration of drive fluid,
• at least one cooling device for cooling drive fluid, and
• at least one control device, by means of which the feed drive and / or the tool drive is or can be controlled,

wherein at least the feed drive and the tool drive can be arranged or arranged together in a container. In particular, the present application relates to operating facilities for the production of so-called "utility tunnels" whose inside diameter is typically in the range between 0.2 m and 5.0 m.

Furthermore, the present application relates to a method for producing a tunnel in a ground by means of a tunnel boring device.

For the purposes of the present application, "soil" is understood as meaning both a soil and rocky ground, for example rock. In the area of geodesic elevations, the floor in the context of the present application can also be flush with a subsequent top surface. In such tunnels, the tunnel boring device is guided directly from a height level of the ground level into an elevation, for example a mountain.

For the purposes of the present application, the "feed drive" designates that drive which is suitable for advancing the tunnel boring device in the ground. In usually the feed drive comprises a hydraulic unit, by means of which a feed press can be driven. This feed press may either act directly or indirectly on the tunnel boring device and thereby continue to drive it in the ground such that the tunnel boring device travels along a longitudinal axis of the tunnel under construction.

As such, the tunnel boring device comprises at least one removal tool with which the respective ground can be removed such that the tunnel is produced. In particular, the removal tool may be formed by a cutting wheel which is rotationally driven about an axis of rotation parallel to a longitudinal axis of the tunnel, wherein cutting cassettes arranged on the cutting wheel engage with the material of the soil and thereby remove it successively. It is understood that for the purposes of the present application, all mining tools are meant in principle, which are suitable for removing soil.

Analogous to the feed drive referred to the "tool drive" in the sense of the present application, a drive by means of which the removal tool is driven. The tool drive is usually formed by a hydraulic unit, which is in operative connection by means of hydraulic lines with a motor of the mining tool.

For the purposes of the present application, a "container" is understood to be a structural unit which closes off an interior space to the outside by means of space-limiting elements, in particular by means of walls, a ceiling and a floor in relation to the environment. In particular, such containers can be formed by sea containers, which can be easily transported by truck on the road. In such an embodiment, the operating device can be transported as such very easy between different installation locations.

State of the art

Operating equipment of the type described above are already known in the art. They can be referred to as so-called "compact container", wherein such a "compact container" stored the operating equipment of the type described above as a whole within a single container and the compact container is placed on the site. The respective tunnel boring device, with which a respective tunnel is to be produced, is then connected by means of hydraulic lines to the compact container, so that a respective excavation tool of the tunnel boring device is fluidically connected to the tool drive. By means of operation of the tool drive, the removal tool can then be driven. Parallel to this a respective feed press is operated by means of the feed drive, so that the tunnel boring device as a whole is moved in the ground in the direction of a desired tunnel axis.

The operation of the tool drive within the container becomes problematic as soon as the tunnel to be created exceeds a certain limit length. It is understood that the hydraulic lines, by means of which the removal tool is connected to the tool drive, must be carried out in the same way very long or win with progressive propulsion of the tunnel boring in the ground analog to length, since the distance between the compact container and the Tunnel boring machine grows. Finally, as the length of the tunnel increases, the problem arises that the friction losses occurring within the hydraulic lines become such that the fluid pressure of the drive fluid effectively arriving at the excavation tool is insufficient to drive the engine of the excavation tool in the desired manner.

In order to counteract this problem, operating devices are furthermore known in the state of the art in which the tool drive, together with components assigned to it, is guided inside the tunnel behind the removal tool. In other words, the tool drive as such is moved in the same way within the tunnel in which the tunnel boring device is also moved. In this way, the hydraulic lines, by means of which the tool drive is connected to the removal tool, regardless of the length of the tunnel to be created permanently be kept to a small length. Such external drives for the mining tool, which can be performed within the tunnel, can also be referred to as so-called "tunneling units". It is understood that for the operation of the respective tunnel boring (actually) no compact container is necessary, since the arranged in the compact container tool drive is not suitable to drive the removal tool over the entire length of the respective tunnel away. Accordingly, so-called "press containers" are used regularly, which merely comprise the feed drive and associated components in order to be able to operate the respective feed press.

As an alternative solution, it is also common in practice to provide a compact container for creating a long tunnel, which is used exclusively for driving a feed drive for operating the feed press, while the tool drive located in the compact container is broke. The latter is by means of a provided additional tunnel aggregate, which is guided behind the removal tool ago.

Overall, it follows that in the prior art, depending on each individually created tunnels a variety of different facilities or parts of the same must be kept, in many cases even to create a single tunnel is to provide an excess of drives, of which then at least one tool drive remains completely unused and thus ultimately produces significant disadvantages in terms of cost-effectiveness.

task

It is therefore the object of the present invention to provide an operating device and a method for producing a tunnel, by means of which a more efficient creation of tunnels than the prior art is possible.

solution

The underlying object is achieved in that the tool drive can be removed from the container. For this purpose, it is essential to the invention that the operating device has a second fluid tank, wherein one of the fluid tanks dedicated to the feed drive and the other fluid tank dedicated to the tool drive are assigned. The fluid tank associated with the tool drive then forms, together with the tool drive, a tool drive module which can be removed as a whole from the container. In this way, the tool drive can be operated independently both inside and outside of the container.

The removal of the tool drive module from the container is preferably possible in such a way that an operative connection between the tool drive and the associated fluid tank remains continuously. This operative connection exists in particular in hydraulic lines which permit an exchange of a drive fluid, in particular of an oil, between the tool drive and the fluid tank. In particular, such an embodiment is to be preferred in which the tool drive and the fluid tank do not change their relative positions relative to each other during the removal of the tool drive module.

The operating device according to the invention has many advantages. Compared to the prior art, it allows, above all, that the operator of the operating device can freely decide depending on the particular tunnel to be created whether he is the Tool drive operates within the container or removes selbigem and leads analogous to a tunneling unit inside the tunnel behind the mining tool ago. In this way it is not necessary for the operator to provide a plurality of different operating devices, for example both a compact container and a press container as well as a separate tunnel unit, of which then at least temporarily individual operating equipment lying idle, as they are not suitable for a respective construction project or . are suitable. In other words, the invention helps to significantly reduce the investment costs in necessary working material, which is required in order to offer services in the field of tunneling.

Another advantage of the operating device according to the invention consists in the second fluid tank, which is used in principle for the operation of the tool drive, that is, even if the tool drive or the tool drive module is disposed within the container. This condition most closely resembles the compact container described above in which both the feed drive and the tool drive are permanently located within the container. In contrast to the compact container, however, the operating device according to the invention permanently has separate fluid tanks for the feed drive and the tool drive, while the two drives share a common fluid tank in the compact container. The latter is disadvantageous insofar as the respective drive fluid, which is held in the common fluid tank, has to be completely replaced every time it is dirty. Such contaminants occur primarily at the entrance of the nascent tunnel, since the hydraulic lines, which are led from the tool drive to the mining tool, must be separated every time a further tube segment of the tunnel is inserted and then reconnected. This regularly leads to an increased entry of dirt in the hydraulic lines, which eventually ends up in the common fluid tank. As a result, in the prior art, the common drive fluid of the feed drive and the tool drive as a whole must be changed as a whole, although the feed drive per se hardly contributes to contamination of the drive fluid in the common fluid tank.

In the embodiment of the invention, the fluid tank of the feed drive is now isolated from the fluid tank of the tool drive, even if the tool drive module is operated within the container. This has the consequence that an exchange of drive fluid in the course of a strong pollution thereof must take place exclusively for the tool drive, while the drive fluid of the feed drive can remain in the fluid tank. This allows the cost of new drive fluid and environmental impact in the course of the replacement of the drive fluid can be significantly reduced. Furthermore, wear of the feed drive due to contaminated drive fluid can be significantly reduced. Also, the drive fluid of the feed drive in the separate execution of the fluid tanks is not affected in the known manner by the temperature input, which is mainly due to the mining tool.

In an advantageous embodiment of the operating device according to the invention, the tool drive module can be removed from the container in such a way that at least the tool drive and the fluid tank assigned to it do not change their positions relative to one another in the course of removal. In particular, a distance between the tool drive and the associated fluid tank does not change during the removal of the tool drive module from the container. This advantageously applies to all components of the tool drive module. As such, in addition to the tool drive and the associated fluid tank, for example, an associated cooling device, a filtering device, a control unit and the like may be present. This will be dealt with separately below.

The operating device further ausgestaltend the tool drive module comprises a support unit on which at least the tool drive and the associated fluid tank are arranged. In a particularly advantageous manner, the fluid tank is used directly as a carrying unit and thus fulfills a dual function, namely the storage of the drive fluid and the "carrying" components of the tool drive module. If the carrying unit is formed by the fluid tank, the fluid tank is "arranged on the support unit" in the sense of the present application.

Advantageously, all components of the tool drive module are arranged on the support unit. This has the particular advantage that for removal of the tool drive module from the container, only the support unit must be solved as such and then removed as a whole from the container. In other words, the tool drive module can be detached from the container by releasing one or more central connection means so that the tool drive module as a whole can be removed. A solution of individual connection means, which interact directly with individual components of the tool drive module, thus eliminated.

Conversely, after a removal of the tool drive module a repeated insertion of the same in the container just as easily done by simply the Carrying unit is introduced together with the rest of the tool drive module in the container and optionally there fastened by means of connecting means. It is understood that in a particularly advantageous embodiment, arranged on the support unit components of the tool drive module maintained their relative orientation to each other throughout. In particular, the tool drive module should be configured together with its support unit such that no removal of individual components of the tool drive module is necessary for the removal of the tool drive module, but selbiges solely by disassembly of the extent parent support unit on which the components of the tool drive module are arranged, can take place ,

In addition, using a support unit described above, it is further preferred if the container has a receptacle for the tool drive module, which is tuned to the support unit, so selbige umbaufrei in or on the receptacle mountable and also vice versa umaubaufrei again disassembled from the receptacle is. For the purposes of the present application, the term "assembly-mountable" or "dismantlable dismantling" is understood to mean that the tool drive module as such does not have to be changed in order to be removed from the container or, conversely, to be used again in the same. Consequently, such embodiments in which, for example, for the removal of the tool drive module of the tool drive or the fluid tank or one or more other possible components separately disassembled and then must be remounted after removal, to be considered disadvantageous. Instead, the interaction between the container and the tool drive module should be as simple as possible by means of the least possible connection means or joints, so that a speedy and easier installation and removal of the tool drive module can be done.

The operating device according to the invention further ausgestaltend selbige has a control unit which is associated with the tool drive and having a connection with the control device, which may be arranged in particular fixed in the container. The control unit interacts with the tool drive in such a way that it can process control signals received by the control device and thus electrically control the tool drive or individual components thereof. Such a control unit is preferably designed as a component of the tool drive module and also installed together with the tool drive and the associated fluid tank on a common support unit. The control unit has the particular advantage that the tool drive module in its developed, guided behind the removal tool forth only a very small number of connecting lines with the container or the control device installed there requires. In particular, it is generally sufficient to lead only a single data line from the control device to the control unit and processed via this data line control signals only locally on the tool drive module and split to control the various components of the tool drive module. In this way, the control unit allows a particularly simple external operation of the tool drive module outside of the container.

In a particularly advantageous embodiment, the control unit cooperates with a maximum of three input lines, which connect the control unit to the container. At least one of these input lines is formed by the data line already mentioned above. Furthermore, at least one input line is formed by an electric line which supplies the control unit with electric current. It may be advantageous if the control unit further comprises a further electric line, wherein the two electric lines each electrical current at different voltage levels, in particular to 400 V and 960 V, provide. For the purposes of the present application, "input lines" are to be understood as meaning only those lines which are in operative connection with the control unit. Thus, lines that are not decisive for the operation and the operation of the control unit or remain ineffective in this regard, however, are nevertheless connected to the control unit, and it is only structurally, no input lines in the sense of the present application.

In a further advantageous embodiment of the operating device according to the invention, this comprises a second, the tool drive associated cooling device. This is preferably also formed as a component of the tool drive module and further also arranged on a common support unit with the other components of the tool drive module. The second cooling device has the advantage that the drive fluid of the tool drive can be cooled directly to the tool drive module. In particular, a return to the container for using the cooling device installed there is not required.

For the success of the invention is basically of secondary importance, in which way the second cooling device is formed. This can in particular be designed in multiple stages, wherein a direct cooling of the drive fluid is carried out for example by means of a liquid-liquid heat exchanger, by means of which the heat energy of the drive fluid is transferred to a coolant, for example glycol. This coolant can then in a second Stage are also cooled by means of a liquid-liquid heat exchanger, in particular, a transition from heat energy to water is conceivable. Here, the use of so-called "feed water", which is used to operate the tunnel boring device in the area of the mining tool, is particularly suitable. This feedwater can then at least indirectly dissipate the heat energy of the drive fluid in a secondary function. Alternatively, it is also conceivable for the second stage of the cooling device that the coolant is cooled by means of an air-liquid heat exchanger. It is understood that a plurality of other variants is also conceivable, for example, an immediate cooling of the drive fluid by means of an air-liquid heat exchanger or an immediate cooling of the drive fluid by means of said feedwater.

Furthermore, such an operating device may be of particular advantage, which has a second, the tool drive associated with the filtering device, which is used for filtering the reproached in the second fluid tank drive fluid. For this purpose, the second filtration device is directly fluidically connected to the second fluid tank. It is also understood here that the second filtration device is preferably designed as a component of the tool drive module.

Furthermore, such an operating device may be advantageous, which has at least one transformer which is assigned at least to the tool drive, preferably only to the tool drive. Such a transformer preferably provides an output voltage of 960V. The high voltage level is useful to overcome relatively long distances between the container and the tool drive, as resistance losses would be otherwise unacceptable using a lower voltage level over long lines and correspondingly electric cables with significantly increased cross-section would have to be used. In the prior art, such a transformer in conjunction with compact containers is consequently not required, since the tool drive is arranged in each case directly in the container. Long lines therefore do not fall on. According to the tool drive of the operating device according to the invention, regardless of its place of use, that is, either within the container or outside thereof, supplied with a voltage of 960 V, or is connected to the transformer, which provides 960V connected. In this way, the tool drive module is in any case also suitable for being guided in a tunnel, wherein a distance between the tool drive module and the container can be quite considerable.

1. a) Ein Werkzeugantriebsmodul, das zumindest einen Werkzeugantrieb sowie einen mit dem Werkzeugantrieb zusammenwirkenden Fluidtank umfasst, wird aus einem Container entnommen, der neben dem Werkzeugantrieb ferner einen Vorschubantrieb beinhaltet, mittels dessen die Tunnelbohrvorrichtung in dem Boden zumindest abschnittsweise vorgeschoben wird.
2. b) Das Werkzeugantriebsmodul wird in den im Entstehen begriffenen Tunnel eingeführt.
3. c) Das Werkzeugantriebsmodul wird während eines Tunnelvortriebs hinter einem Abbauwerkzeug her geführt.

In procedural terms, the underlying object is achieved according to the invention by the following method steps:

1. a) A tool drive module comprising at least one tool drive and a co-operating with the tool drive fluid tank is removed from a container, which further includes a feed drive in addition to the tool drive, by means of which the tunnel boring device is advanced in the ground at least in sections.
2. b) The tool drive module is introduced into the nascent tunnel.
3. c) The tool drive module is guided behind a removal tool during tunneling.

The method according to the invention can be carried out particularly easily by means of the operating device according to the invention. It has the particular advantage that the tool drive module can be used in both "short tunnel" and "long tunnel" modes by either removing the tool drive module from the container or reinserting it into the container. The essential step of the invention thus consists in that the tool drive module is removed from a container. This is just not possible in the prior art when using a conventional compact container and when using a typical tunneling unit.

The method is also particularly advantageous if the tool drive module is inserted into the container again in a period of time after a completion of a respective tunnel and before the creation of another tunnel. In other words, the operator of the respective operating device is free to remove or reinsert the tool drive module from the container. In particular, depending on the construction situation, he can decide how he would like to proceed.

In particular, in the course of the production of a long tunnel in which the tool drive module is removed from the container in the course of the production of the tunnel and then introduced into the tunnel, it may be of particular advantage, the drive fluid of the tool drive during a start-up period by means of a first fixed Cooling device installed in the container and to cool by means of a second cooling device arranged on the tool drive module during a propulsion period located after the start-up period. The "start-up period" describes the period of time within which an initial section of the tunnel to be created is produced. Typically, this initial section connects directly to a launch shaft, from which the respective tunnel is introduced into the ground. In general, the start-up period includes the introduction of the tunnel boring device in the ground and the introduction of a behind tunnel boring device, not permanently remaining in the ground tube. It is understood that in such a state no tunnel section has yet been made into which the tool drive module could be inserted.

The procedure described is particularly advantageous over the prior art. In the prior art - as described above - used to produce a long tunnel, a tunneling unit, which is arranged in any case outside a container. In order to cool such a tunnel aggregate, as a rule, the feed water already described above is used. Here, a feedwater line is connected to the tunneling unit, so that it can cooperate in a cooling manner with the tunneling unit or the drive fluid used there. This procedure is disadvantageous within the described start-up period for several reasons. On the one hand, the coupling of the tunneling unit is comparatively cumbersome, since for this purpose the feedwater line has to be interrupted at the location of the tunneling unit. As soon as the tunneling unit is guided into the tunnel, the feedwater line must be coupled at the location of the tunneling unit. Furthermore, the handling of the feedwater line as such is comparatively expensive, since it is a line with a comparatively large diameter and high rigidity. Especially on small construction sites that need to be operated in a confined space, for example in road construction, it can be a considerable effort to connect a tunneling unit in the feedwater pipe.

By contrast, the method according to the invention provides cooling of the drive fluid of the tool drive by means of the cooling device installed in the container, that is to say by means of the cooling device which is assigned to the feed drive. In other words, the tool drive module can be connected to the cooling device of the container during the start-up period, so that the integration of the tool drive module into the feedwater line, as is typically required in the prior art, can be dispensed with. As a result, the construction process during the startup period of the tunnel to be created is considerably simplified and accelerated.

Preferably, the drive fluid of the tool drive during the Anfahrzeitraums at least indirectly by means of an air-liquid heat exchanger and cooled during the propulsion period by means of a working fluid of the tunnel boring device. The "working fluid" may be, in particular, the feed water described above, which is used for the purpose of discharging material to the mining tool. Preferably, the drive fluid of the tool drive is cooled during the Anfahrzeitraums directly by means of the air-liquid heat exchanger, namely by means of the permanently installed in the container cooling device. In this case, despite the otherwise complete separation of the circuits of the drive fluids to a slight mixing of the drive fluids of the feed drive and the tool drive can come.

The cooling of the drive fluid of the tool drive during the propulsion period is preferably carried out only indirectly by means of an intermediate cooling stage. This is due to the fact that the cooling by means of the working fluid of the tunnel boring device is subject to a realistic risk of damage, which is due to the high loading of the working fluid with abrasive components. The latter can be formed in particular by degradation products during the construction of the tunnel. These abrasive components can "sweep" a line of the working fluid over time. Since it is customary to circumscribe said line of the working fluid directly with the respective coolant to be cooled, the described looping through the line of the working fluid would result in an immediate entry of the coolant with the working fluid of the tunnel boring device. An immediate cooling of the drive fluid in this context would mean that selbiges is entered in the course of damage to the line of the working fluid in the working fluid. Such an entry has the potential to cause severe damage to the environment. Conversely, components of the working fluid can enter the drive fluid, which can lead to irreparable damage to the tool drive.

Therefore, it is advantageous to provide a secondary cooling circuit, which is equipped with a comparatively harmless coolant, such as glycol. In such a constellation, heat energy of the drive fluid of the tool drive is first transferred by means of a liquid-liquid heat exchanger to the respective coolant and then the latter is cooled by means of the working fluid. A possibly impending entry of the harmless coolant into the working fluid and thus into the environment is then comparatively uncritical.

In a further advantageous embodiment of the method according to the invention, the tool drive module is re-inserted into the container after completion of a respective tunnel construction site, which may well include the creation of several individual tunnels. In this way, the tool drive module can be particularly simple be removed within the container of the tunnel construction site, for example, the next tunnel construction site or the construction of the respective executing company.

Furthermore, the present invention provides a method for producing a tunnel, in which the operating device according to the invention is used, wherein the tool drive module is operated within the container. This mode of operation is in principle to be compared with that of a compact container, but the latter does not use the operating device according to the invention with two fluid tanks.

The operating device according to the invention and the method according to the invention are explained in more detail below with reference to an exemplary embodiment, which is illustrated in the figures. It shows:

A perspective view of a tool drive module.

The present invention, which is incorporated in the FIGS. 1 to 3 1, as well as a tunnel boring device 2 for creating a tunnel 3 in a floor 4. The tunnel 3 to be created here has an internal diameter of 1.4 m. The operating device 1 comprises a container 12, which is designed here in the form of a sea container. Within the container 12 , a feed drive 5 is arranged, which is adapted to drive a feed press, not shown in the figures. The latter is adapted to be used in a launch shaft 23 and there by means of cooperation with a respective, the feed press facing pipe segment 22 of the tunnel 3 to accomplish the propulsion of the tunnel boring device 2 within the bottom 4 . By means of successive introduction of further pipe segments 22 into the tunnel 3 , a finished tunnel 3 thus finally results , which is completely formed with pipe segments 22 from the beginning to the end.

Within the container 12 of the operating device 1 are permanently, that is permanently installed, a fluid tank 8 for providing a drive fluid, a filter 9 for Filtration of the drive fluid and a cooling device 10 is provided for cooling the drive fluid. The feed device 5 is formed in the example shown by a hydraulic unit, which is operated with oil as drive fluid. The cooling device 10 is designed here in the form of an air-liquid heat exchanger. Furthermore, the operating device 1 within the container 12 has a control device 11 which is responsible for the control of both the feed drive 5 and the tool drive 6 , the latter in the example shown only indirectly, which will be discussed separately below.

In an in FIG. 1 illustrated state of the operating device 1 is a tool drive module 14, which includes a tool drive 6 , disposed within the tunnel 3 behind a mining tool 7 of the tunnel boring device 2 . The tool drive module 14, which, in particular, with reference to the view according FIG. 3 results in addition to the tool drive 6 as such further includes a tool drive 6 associated fluid tank 13, a cooling device 17 and a filter 18. Thus, the tool drive 6 has its own fluid tank 13 which is completely independent of the fluid tank 8 of the feed drive 5 is formed. The feed drive 5 and the tool drive 6 therefore have completely decoupled drive fluid circuits. The tool drive 6, the fluid tank 13, the cooling device 17 and the filtration device 18 are all formed as components of the tool drive module 14 in the example shown. The latter further comprises a support unit 15, which is formed in a particular manner of the fluid tank 13 in the example shown. In the example shown, consequently, the structure of the fluid tank 13 simultaneously acts as a support unit 15 and vice versa, the support unit 15 simultaneously as a fluid tank 13. The support unit 15 is equipped with a plurality of support hooks 19 , a particularly simple transport of the entire tool drive module 14, for example by means of a Allow cranes. The components of the tool drive module 14 are mounted on the support unit 15 in a force-transmitting manner.

Furthermore, the tool drive module 14 comprises a control unit 16, which is suitable for the direct control of the individual components of the tool drive module 14 . In other words, the control unit 16 forms a kind of subdistribution to the control device 11, so that operation of the tool drive module 14 is also possible outside of the container 12 , without a vast number of individual control lines directly from the controller 11 to the respective individual components of the tool drive module 14, the are to be driven lead to have to. The control unit 16 is similarly provided as a component of the tool drive module 14 and mounted on the support unit 15th

In the FIG. 1 shown operating situation of the operating device 1 is provided in particular for the creation of long tunnel 3 , whose length exceeds a certain limit, which no longer allows driving of the mining tool 7 from the container 12 out. Accordingly, the tool drive module 14 as such according to the invention is removed from the container 12 and inserted into the tunnel 3 , so that it can be performed directly behind the mining tool 7 ago. This has the advantage that hydraulic lines 25, which connect the tool drive 6 with the removal tool 7 , regardless of the length of the tunnel 3 in each case can be made short. Friction losses within the hydraulic lines 25 can thus be reduced to a minimum.

The tool drive module 14 is designed in the example shown in such a way that in the course of its "tunneling operation" ( FIG. FIG. 1 ), in the course of which it is located within the tunnel 3 to be created, can be cooled by means of a working fluid of the tunnel boring device 2 . This relates to the cooling of the drive fluid of the tool drive 6. For this purpose, the tool drive module 14 has a feedwater line 20 and a cooperating with this liquid-liquid heat exchanger, which is not shown in the figures. The feedwater line 20 is guided in the longitudinal direction of the tool drive module 14 through the same. The so-called "feed water" forms here the working fluid of the tunnel boring device 2. The cooling of the drive fluid takes place in the example shown by means of a two-stage cooling. In this first the drive fluid is cooled by means of the cooling device 17 , which is formed here in the form of a liquid-liquid heat exchanger. By means of the cooling device 17 , heat energy of the drive fluid is transferred starting from selbigem to a coolant, which is formed here by a water-glycol mixture. Said coolant is circulated by means of a coolant pump 21 and, starting from the cooling device 17, is brought into direct contact with an outer jacket surface of the feedwater line 20 . Since the temperature of the feedwater is comparatively low, it comes by means of the feedwater line 20 to a heat transfer from the coolant via the feedwater line 20 to the feedwater, which ultimately dissipates the heat energy from the tool drive module 14 . The cooled coolant is then again able to absorb heat energy from the drive fluid of the tool drive 6 in the cooling device 17 .

In the course of operation of the tool drive module 14 within the container 12 , it is particularly easy to carry out the cooling of the drive fluid of the tool drive 6 by means of the built-in cooling device 10 in the container 12 . For this purpose, it is only necessary to connect coolant lines of the cooling device 10, for example, to the cooling device 17 of the tool drive module 14 , in particular by means of quick-release couplings, which can be connected to a designated port 26 . An excess of heat energy of the coolant of the tool drive module 14 can then be removed by means of the cooling device 10 designed as an air-liquid heat exchanger in the example shown.

A connection of the tool drive module 14 to the container 12 takes place in the example shown according to FIG. 1 only by means of a wiring harness 24. In this case, this comprises, in particular, a data line, by means of which control signals of the control device 11 can be transferred to the control unit 16 , as well as two electrical lines. The former is used to supply the control unit 16 with electric current, wherein the control unit 16, a voltage of 400 V is provided. The third line is used to supply the tool drive 6 with electric current, which is due to the relatively high power required by the tool drive 6 and its electric motor, to avoid power losses, a higher voltage level of 960 V here is used. A corresponding transformer 27, which transforms the externally provided input voltage of 400 V to said level of 960 V, is permanently installed in this container 12 .

Alternatively, it is also conceivable to form a transformer as part of the tool drive module 14 , which transformer would be suitable for transforming a high voltage level, for example one of 960 V, to a lower voltage level, in particular 400 V. The supply of the control unit 16 could thus take place directly on the tool drive module 14 , so that overall the tool drive module 14 would only need a single electrical line for supplying the same with electric current.

The tool drive module 14, in particular its support unit 15, is designed in such a way that the tool drive module 14 can be inserted into or removed from the container 12 in its entirety and without any conversion. For this purpose, the container 12 preferably has a corresponding receptacle. A condition in which the tool drive module 14 is located within the container 12 ("container operation") is particularly FIG. 2 refer to. Since all components of the tool drive module 14 in the example shown each provided for them Positions are arranged on the support unit 15 , it follows that the individual components in the course of insertion or removal of the tool drive module 14 in or out of the container 12 do not change their relative positions to each other. In any case, the tool drive module 14 is designed such that an operative connection can at least remain between the tool drive 6 and the associated fluid tank 13 continuously.

An operation of the operating device 1 according to the invention in the in FIG. 2 shown, in which the tool drive module 14 is disposed continuously within the container 12 , in particular in the course of the production of short tunnel 3 can be applied. Such tunnels are so short that a maximum necessary length of hydraulic lines 25, which connect the tool drive 6 with the removal tool 7 of the associated tunnel boring device 2 , do not exceed a respective limit which would lead to excessive friction losses within the hydraulic lines 25 . Thus, in such situations insertion of the tool drive module 14 into the tunnel 3 in the in FIG. 1 shown way not required.

The operating device 1 according to the invention can therefore be used both in a "container operation" ( US Pat. FIG. 2 ) as well as in a "tunnel operation" ( FIG. 1 ) , wherein a change between these two modes due to the uniform design of the tool drive module 14 with its support unit 15 and the vote of the design of the tool drive module 14 and a complementary receptacle in the container 12 is particularly easy and fast possible. Provision of a known tunneling unit for the creation of long tunnels is therefore no longer required by means of the operating device 1 according to the invention. When creating a short tunnel, it is also not necessary to store a respective separate tunneling unit, as is known in the art, outside of a protective shell, such as a container, and to suspend the respective weather conditions and pollution loads of a typical construction site. Furthermore, additional costs can be avoided, which are usually borne by the typically public clients and thus ultimately by the general public. Instead, the tool drive module 14 of the operating device 1 according to the invention can be readily inserted into the container 12 and is thus protected from external influences.

It is understood that the features described above in connection with the exemplary embodiment can in principle act independently of one another and thus do not necessarily depend on the feature combination set out in the exemplary embodiment.
