Definitions

  • the present application relates to a method for producing a tunnel in a ground using a tunnel boring device.
  • “soil” is understood to mean both soil and stony subsoil, for example rock.
  • the ground within the meaning of the present application can also end flush with an adjoining top edge of the terrain.
  • the tunnel boring device is guided directly from a height level of the upper edge of the terrain into an elevation, for example a mountain.
  • the “advance drive” refers to that drive which is suitable for advancing the tunnel boring device in the ground.
  • the feed drive includes a hydraulic unit, by means of which a feed press can be driven. This feed press can act either indirectly or directly on the tunnel boring device and thereby advance it in the ground in such a way that the tunnel boring device moves along a longitudinal axis of the tunnel under construction.
  • the tunnel boring device as such comprises at least one excavation tool with which the respective soil can be removed in such a way that the tunnel is produced.
  • the excavation tool can in particular be formed by a cutting wheel, which is driven in rotation about an axis of rotation parallel to a longitudinal axis of the tunnel, with cutting cassettes arranged on the cutting wheel engaging with the material of the soil and thereby gradually removing it. It goes without saying that within the meaning of the present application, all excavation tools that are suitable for excavating soil are meant in principle.
  • the "tool drive” in the sense of the present application designates a drive by means of which the removal tool can be driven.
  • the tool drive is also usually formed by a hydraulic unit that is operatively connected to a motor of the mining tool by means of hydraulic lines.
  • a “container” is understood to mean a structural unit which closes off an interior space from the outside by means of space delimiting elements, in particular by means of walls, a ceiling and a floor.
  • such containers can be formed by sea containers that can be particularly easily transported by truck on the road. With such an embodiment, the operating equipment as such can be transported particularly easily between different installation sites.
  • the tool drive can be removed from the container.
  • the operating device has a second fluid tank, with one of the fluid tanks being dedicated to the feed drive and the other fluid tank being dedicated to the tool drive.
  • the fluid tank assigned to the tool drive then forms, together with the tool drive, a tool drive module that can be removed as a whole from the container. In this way, the tool drive can be operated independently both inside and outside 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 fluid tank assigned to it is maintained throughout.
  • This operative connection consists in particular in hydraulic lines which allow an exchange of a drive fluid, in particular an oil, between the tool drive and the fluid tank.
  • a drive fluid in particular an oil
  • such an embodiment is to be preferred in which the tool drive and the fluid tank do not change their relative positions to one another in the course of the removal of the tool drive module.
  • the operating facility according to the invention has many advantages. Compared to the prior art, it allows above all that the operator of the operating facility can decide freely depending on the tunnel to be created in each case whether he Tool drive operates within the container or removes it from the same and leads analogously to a tunnel unit within the tunnel behind the dismantling tool. In this way, it is not necessary for the operator to keep a large number of different operating facilities available, for example both a compact container and a press container as well as a separate tunnel unit, of which individual operating facilities then lie idle at least temporarily because they cannot be used for a particular construction project or are not available . are suitable. In other words, the invention helps to significantly reduce the investment costs in necessary working materials, which are required to be able to offer tunneling services.
  • a further advantage of the operating device according to the invention is the second fluid tank, which is basically used to operate the tool drive, ie even when the tool drive or the tool drive module is arranged inside the container.
  • This condition most closely resembles the compact container described above, in which both the feed drive and the tool drive are permanently arranged inside the container.
  • the operating facility according to the invention permanently has separate fluid tanks for the feed drive and the tool drive, while both drives in the compact container share a common fluid tank.
  • the latter is disadvantageous insofar as the respective drive fluid, which is stored in the common fluid tank, has to be completely replaced every time it is dirty.
  • the fluid tank of the feed drive is now isolated from the fluid tank of the tool drive, even when the tool drive module is operated inside the container. This ultimately has the consequence that an exchange of drive fluid must take place in the course of heavy soiling of the same exclusively for the tool drive, while the drive fluid of the feed drive can remain in its fluid tank. This allows the costs for new drive fluid and the ecological impact of replacing the drive fluid are significantly reduced. Furthermore, wear and tear on the feed drive as a result of contaminated drive fluid can be significantly reduced. In the separate design of the fluid tanks, the drive fluid of the feed drive is also not affected in the known manner by the temperature input, which is mainly due to the mining tool.
  • the tool drive module can be removed from the container in such a way that during the removal at least the tool drive and the fluid tank assigned to it do not change their positions relative to one another.
  • a distance between the tool drive and the associated fluid tank does not change when the tool drive module is removed from the container.
  • an associated cooling device, a filtering device, a control unit and the like can be present in addition to the tool drive and the associated fluid tank. This is dealt with separately below.
  • the tool drive module comprises a support unit on which at least the tool drive and the fluid tank assigned to it are arranged.
  • the fluid tank is used directly as a carrying unit and thus fulfills a dual function, namely storing the drive fluid and “carrying” components of the tool drive module. If the carrying unit is formed by the fluid tank, the fluid tank is “arranged on the carrying unit” within the meaning of the present application.
  • All components of the tool drive module are advantageously arranged on the support unit.
  • This has the particular advantage that, in order to remove the tool drive module from the container, only the carrying unit as such has to be detached and can then be removed from the container as a whole.
  • the tool drive module can be detached from the container by releasing one or more central connecting means, so that the tool drive module can be removed as a whole.
  • a solution of individual connecting means, which interact directly with individual components of the tool drive module, is therefore not necessary.
  • the Carrying unit is introduced together with the rest of the tool drive module in the container and optionally fixed there by means of fasteners.
  • the components of the tool drive module arranged on the support unit continuously maintain their relative orientation to one another.
  • the tool drive module together with its support unit should be designed in such a way that no dismantling of individual components of the tool drive module is necessary to remove the tool drive module, but the same can be done solely by dismantling the superordinate support unit on which the components of the tool drive module are arranged .
  • the container has a mount for the tool drive module that is matched to the support unit, so that the same can be mounted in or on the mount without modification and, conversely, can be removed from the mount without modification is.
  • mountable without modification or “dismountable without modification” is understood to mean that the tool drive module as such does not have to be changed in order to be able to be removed from the container or, conversely, reinserted into it. Consequently, those designs in which, for example, the tool drive or the fluid tank or one or more other components must be separately dismantled and then reassembled after removal for the removal of the tool drive module, are to be regarded as disadvantageous.
  • the interaction between the container and the tool drive module should be as simple as possible using as few connecting means or connection points as possible, so that the tool drive module can be installed and removed quickly and easily.
  • the same has a control unit, which is assigned to the tool drive and which has a connection to the control device, which can in particular be arranged permanently in the container.
  • the control unit interacts with the tool drive in such a way that it processes control signals received from the control device and can 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 is 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 dismantled state, guided behind the dismantling tool, has only a very small number of connecting lines to the container or the control device installed there.
  • control unit allows a particularly simple external operation of the tool drive module outside the container.
  • the control unit interacts with a maximum of three input lines that 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 electrical line that supplies the control unit with electrical current. In this case, it can be advantageous if the control unit also includes a further electrical line, with the two electrical lines each providing electrical current at different voltage levels, in particular at 400 V and at 960 V.
  • input lines are to be understood as meaning only those lines which are actively connected to the control unit. Consequently, lines that are not decisive for the operation and mode of operation of the control unit or remain ineffective in this regard, but are nonetheless connected to the control unit, even if only structurally, are not input lines within the meaning of the present application.
  • this includes a second cooling device assigned to the tool drive.
  • This is preferably also designed as a component of the tool drive module and also arranged on a common support unit with the other components of the tool drive module.
  • the second cooling device offers the advantage that the drive fluid of the tool drive can be cooled directly at the tool drive module. In particular, it is not necessary to return it to the container in order to use the cooling device installed there.
  • the manner in which the second cooling device is designed is fundamentally of secondary importance for the success according to the invention.
  • This can in particular be multi-stage, with direct cooling of the drive fluid being carried out, for example, by means of a liquid-liquid heat exchanger, by means of which the thermal energy of the drive fluid is transferred to a coolant, for example glycol.
  • a coolant for example glycol.
  • This coolant can then in a second Level are also cooled by means of a liquid-liquid heat exchanger, in particular a transfer of thermal energy to water is conceivable.
  • feed water that is used to operate the tunnel boring device in the area of the excavation tool is particularly useful here. In a secondary function, this feed water can then at least indirectly dissipate the thermal energy of the drive fluid.
  • the coolant is cooled by means of an air-liquid heat exchanger. It goes without saying that a large number of other variants are also conceivable, for example direct cooling of the drive fluid by means of an air-liquid heat exchanger or direct cooling of the drive fluid by means of the feed water mentioned.
  • an operating device can be of particular advantage, which has a second filtering device assigned to the tool drive, which can be used to filter the drive fluid held in the second fluid tank.
  • the second filtering device is directly fluidically connected to the second fluid tank. It is also understood here that the second filtering device is preferably designed as a component of the tool drive module.
  • Such an operating device can be advantageous that has at least one transformer that is assigned at least to the tool drive, preferably only to the tool drive.
  • a transformer preferably provides an output voltage of 960 V.
  • the high voltage level makes sense in order to cover comparatively long distances between the container and the tool drive, since resistance losses would otherwise be unacceptable when using a lower voltage level over long cable distances and electrical cables with a significantly larger cross-section would have to be used accordingly.
  • such a transformer is consequently not required in connection with compact containers, since the tool drive is arranged directly in the container in any case. Long line distances are therefore not necessary.
  • the tool drive of the operating facility according to the invention is supplied with a voltage of 960 V or is connected to the transformer, which provides 960 V, regardless of where it is used, ie either inside or outside the container.
  • the tool drive module is in any case also suitable for being guided in a tunnel, in which case the distance between the tool drive module and the container can be considerable.
  • the method according to the invention can be carried out particularly easily using the operating device according to the invention. It offers the particular advantage that the tool drive module can be used both in an operating mode for “short tunnels” and for “long tunnels” by the tool drive module being either removed from the container or reinserted into the container.
  • the essential method step according to the invention is therefore that the tool drive module is removed from a container. Such is not possible in the prior art when using a conventional compact container or when using a typical tunnel unit.
  • the method is particularly advantageous when the tool drive module is reinserted into the container in a period of time after the completion of a respective tunnel and before the construction of a further tunnel.
  • the operator of the respective operating facility is free to remove the tool drive module from the container or reinsert it.
  • he can decide how he wants to proceed.
  • start-up period describes the period within which an initial section of the tunnel to be built is produced. Typically, this initial section is directly connected to a launch shaft from which the respective tunnel is introduced into the ground.
  • the start-up period includes the introduction of the tunnel boring device into the ground and the introduction of a tube that follows behind the tunnel boring device and does not remain permanently in the ground. It goes without saying that in such a state no tunnel section has yet been produced into which the tool drive module could be introduced.
  • a tunnel unit is used to produce a long tunnel, which is always arranged outside of a container.
  • the feed water already described above is generally used.
  • a feed water line is connected to the tunnel unit so that it can interact with the tunnel unit or the drive fluid used there in a cooling manner.
  • This procedure is disadvantageous for several reasons within the described start-up period.
  • the coupling of the tunnel unit is comparatively cumbersome since the feed water line has to be interrupted at the point of the tunnel unit. As soon as the tunnel aggregate is then guided into the tunnel, the feed water line must be coupled at the point of the tunnel aggregate.
  • the handling of the feed water line as such is comparatively complex, since it is a line with a comparatively large diameter and high rigidity.
  • it can mean considerable effort to connect a tunnel unit to the feed water line.
  • the procedure according to the invention provides for cooling of the drive fluid of the tool drive by means of the cooling device installed in the container, ie by means of the cooling device which is assigned to the feed drive.
  • 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 feed water line, as is typically required in the prior art, can be omitted. This significantly simplifies and accelerates the construction process during the start-up period of the tunnel to be built.
  • the drive fluid of the tool drive is preferably cooled at least indirectly by means of an air-liquid heat exchanger during the start-up period and by means of a working fluid of the tunnel boring device during the advance period.
  • the "working fluid" can in particular be the feed water described above, which is used for the purpose of material discharge at the mining tool.
  • the drive fluid of the tool drive is preferably cooled directly during the start-up period by means of the air-liquid heat exchanger, namely by means of the cooling device permanently installed in the container. Despite the otherwise complete separation of the circuits of the drive fluids, there may be a slight mixing of the drive fluids of the feed drive and the tool drive.
  • the cooling of the drive fluid of the tool drive during the propulsion period preferably takes place only indirectly by means of an intermediate cooling stage.
  • the latter can be formed in particular from degradation products during the construction of the tunnel.
  • These abrasive components can "grind through" a line of the working fluid over time. Since it is customary for the coolant to be cooled to flow directly around said line of the working fluid, the described looping through of the line of the working fluid would result in a direct entry of the coolant with the working fluid of the tunnel boring device.
  • direct cooling of the drive fluid would mean that the same would be introduced into the working fluid in the course of damage to the working fluid line. Such an entry has the potential to severely damage the environment. Conversely, components of the working fluid can get into the drive fluid, which can lead to irreparable damage to the tool drive.
  • the tool drive module is reinserted into the container after completion of a respective tunnel construction site, which can certainly also include the construction of several individual tunnels.
  • the tool drive module can be removed particularly easily from the tunnel construction site within the container, for example to the next tunnel construction site or to the building yard of the company carrying out the work.
  • the present invention provides a method for manufacturing a tunnel according to claim 15.
  • the operating device according to the invention is used, with the tool drive module being operated inside the container.
  • This mode of operation is basically the same as that To compare compact containers, but the latter just does not use the operating facility according to the invention here with two fluid tanks.
  • the present invention disclosed in Figures 1 to 3 comprises an operating facility 1 according to the invention and a tunnel boring device 2 for creating a tunnel 3 in a ground 4.
  • the tunnel 3 to be created has an inside diameter of 1.4 m here.
  • the operating facility 1 includes a container 12, which is designed here in the form of a sea container. Inside the container 12 , a feed drive 5 is arranged, which is suitable for driving a feed press, not shown in the figures. The latter is suitable for being inserted into a starting shaft 23 and for driving the tunnel boring device 2 inside the ground 4 there by interacting with a respective pipe segment 22 of the tunnel 3 facing the feed jack. By means of the successive introduction of further pipe segments 22 into the tunnel 3, a finished tunnel 3 finally results, which is completely formed with pipe segments 22 from the beginning to the end.
  • a fluid tank 8 for storing a drive fluid, a filter device 9 for filtering the drive fluid and a cooling device 10 for cooling the drive fluid are permanently, ie permanently installed, inside the container 12 of the operating device 1 .

  • the tool drive module 14, which is particularly based on the representation according to figure 3 comprises, in addition to the tool drive 6 as such, a fluid tank 13 assigned to the tool drive 6 , a cooling device 17 and a filtering device 18.
  • the tool drive 6 therefore has its own fluid tank 13, which is designed completely independently of the fluid tank 8 of the feed drive 5 .
  • 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 filtering device 18 are all designed as components of the tool drive module 14 in the example shown.
  • the latter also includes a carrying unit 15 which is formed in a special way by the fluid tank 13 in the example shown.

  • the carrying unit 15 is equipped with a plurality of carrying hooks 19 , which make it particularly easy to transport the entire tool drive module 14 , for example by means of a allow cranes.
  • the components of the tool drive module 14 are power-transmittingly mounted on the support unit 15 .
  • the tool drive module 14 includes a control unit 16 which is suitable for directly controlling the individual components of the tool drive module 14 .
  • the control unit 16 forms a kind of sub-distribution to the control device 11, so that the tool drive module 14 can also be operated outside of the container 12 without an unmanageable large number of individual control lines directly from the control device 11 to the respective individual components of the tool drive module 14 are to be controlled, to have to lead.
  • the control unit 16 is likewise equipped as a component of the tool drive module 14 and mounted on the support unit 15 .
  • the operating situation of the operating facility 1 shown is intended in particular for the creation of long tunnels 3 , the length of which exceeds a certain limit value which no longer allows the excavation tool 7 to be driven out of the container 12 .
  • the tool drive module 14 as such according to the invention is removed from the container 12 and introduced into the tunnel 3 , so that it can be performed immediately behind the dismantling tool 7 .
  • This has the advantage that hydraulic lines 25, which connect the tool drive 6 to the mining tool 7 , can always be made short, regardless of the length of the tunnel 3 . Frictional losses within the hydraulic lines 25 can thus be reduced to a minimum.
  • the tool drive module 14 is designed in such a way that during its “tunnel operation” ( figure 1 ), In the course of which it is located within the tunnel 3 to be created, by means of a working fluid of the tunnel boring device 2 can be cooled.
  • This relates to the cooling of the drive fluid of the tool drive 6.

  • Said coolant is circulated by means of a coolant pump 21 and, starting from the cooling device 17 , is directed into direct contact with an outer lateral surface of the feed water line 20 . Since the temperature of the feed water is comparatively low, the feed water line 20 causes heat to be transferred from the coolant via the feed water line 20 to the feed water, which ultimately removes the thermal energy from the tool drive module 14 .
  • the cooled coolant is then again able to absorb thermal energy from the drive fluid of the tool drive 6 in the cooling device 17 .
