Definitions

  • a so-called trench wall cutter is arranged vertically adjustable on a mast or cantilever arm.
  • the masts or cantilever arms on the carrier devices usually have a height of 15 m to 30 m or more. The height of the mast is largely determined by the height of the trench wall cutter.
  • Such diaphragm wall milling devices are used to create diaphragm or cut-off walls which can reach depths of up to 100 m and more. Such slotted or sealing walls are used for.
  • This trench wall milling device has a rail-guided carriage with a frame and a cantilever arm, which is only insignificant is higher than a vertical length of a trench cutter.
  • a cable drum for a support cable and connecting cable and a hose drum for a supply hose are mounted on the support frame close to the ground.
  • the trench wall cutter is limited to the essential components, such as cutting wheels, drives, pumps, with a guide frame being designed to be small.
  • the height of use is essentially limited by the height of the trench wall milling machine.
  • a trench wall cutter cannot be reduced in size at will, since a certain size is required for the cutting wheels, the drives, the pump and, in particular, for a guide frame.
  • a trench wall cutter is known in which a maintenance time for changing the cutting teeth on the cutting wheels can be reduced. This is achieved by not replacing individual cutting teeth but a cutting head on the milling frame as a whole.
  • the invention is based on the object of specifying a trench wall milling device and a method for milling a trench in the ground, with which efficient milling is made possible even under particularly cramped spatial conditions.
  • a trench wall milling device is provided with a trench wall milling cutter, which is made up of at least two milling cutter modules, and a supporting structure for suspending and moving the trench wall milling cutter in a vertical direction for forming a cut trench in the ground, the supporting structure has a guide device which is designed to feed the separate milling modules to a work area at which the milling slot is to be created.
  • a basic idea of the invention can be seen in dividing the trench wall cutter into at least two cutter modules which are detachably connected to one another. Furthermore, a support structure is provided for suspending and moving the trench wall cutter in a vertical direction to form the cut trench, the support structure additionally having a guide device for feeding the separate cutter modules. According to the invention, it is therefore no longer necessary to transport a ready-to-use trench wall cutter to a work area at which the cut trench is being created. Instead, according to the invention, the trench wall cutter is divided into its milling modules and fed to the work area and only there assembled into the trench wall cutter.
  • the support structure is designed with a corresponding guide or transport device.
  • the supporting structure can preferably have an overall height which is smaller than the height of the ready-to-use trench cutter. The supporting structure only needs to be the same height or higher than the height of the milling module.
  • milling can also be carried out at work sites where only a very low working height is available, which is even lower than the height of the assembled trench cutter.
  • This can be the case in particular if a so-called guide slot, which can have a depth of about 1 m to 4 m, is prefabricated in the work area, so that one or more cutter modules can already be inserted into the guide slot when assembling the trench wall cutter.
  • the trench wall milling device according to the invention cannot only be used in tunnels or in buildings. Due to the very low overall height, which can be less than 5 m and also less than 3 m, the trench wall milling device can be provided or surrounded overall with a privacy, dust protection and/or sound insulation cover. It is even possible to permanently install the entire trench wall milling device in one or two or three standard containers. This can be particularly the case when milling in cities, inhabited areas, airports or other infrastructure projects, buildings or other sensitive construction site areas.
  • a preferred embodiment of the invention consists in that a first milling module with milling wheels and a second milling module with at least one drive unit are provided.
  • the first cutter module can have the lower section of the trench wall cutter with the cutting wheels and the bearings of the cutting wheels on a base support.
  • the second milling module contains at least one drive unit, preferably for a pump device, which is designed in particular for flushing and/or pumping out suspension with the ground material that has been milled off.
  • this or another drive unit can also be for the cutting wheels.
  • guide elements for guiding and adjusting the milling cutter in the milling slot can also be arranged on the second milling module.
  • extendable adjusting elements can be provided, which can be executed by means of adjusting cylinders, in order to adjust the trench wall cutter in relation to the trench walls.
  • the trench wall cutter can be constructed from a large number of other cutter modules, which can have different functions. It is particularly preferred that at least one further milling module is provided, which has a guide frame.
  • the guide frame can be purely passive as a scaffold-like frame with contact elements for positioning and guiding along the milled trench walls. Preferably, these plate-shaped elements can also be raised in order to bring about a relative change in position in the milled slot.
  • a plurality of such milling modules with guide frames can be arranged, the guiding accuracy and guiding stability of the trench wall cutter in the cut trench being increased with an increasing height of the guide frame. In this way, cut trenches with great depths of up to 100 m and more can be created with good guiding accuracy, even with limited construction heights.
  • a support device is arranged on at least one, preferably the uppermost cutter module, with which the trench wall cutter is held on the support structure via a support cable or a rod-shaped support device.
  • the support structure has at least one guide rail along which the individual cutter modules are mounted so that they can be displaced transversely to the cut trench.
  • the support structure therefore not only allows the trench wall cutter to be displaced vertically in a driving direction, but also a displacement of the individual cutting modules transversely to this driving direction. This allows efficient feeding and removal of the individual milling modules and expedient assembly and disassembly.
  • a displacement device in principle, can be done by hand with suitable bearings.
  • a displacement drive for displacing the milling module.
  • This can be a motor with a pinion, for example, which causes a movement along a rack, for example.
  • a cable mechanism with a cable winch or a linear actuating cylinder or any other suitable drive device can also be provided.
  • the drive can preferably be operated electrically or hydraulically.
  • the milling modules can be connected in any suitable manner that enables the quickest possible detachment and connection.
  • the cutter modules have connecting surfaces which are directed transversely and/or longitudinally to a longitudinal or cutting direction of the trench wall cutter. As a result, connecting surfaces are created that are as large as possible, which allow a particularly stable connection between the individual milling modules.
  • connection devices are both mechanical connection devices in order to couple the milling modules to one another in a stable and firm manner.
  • the connecting devices can also include devices for connecting supply hoses and lines, for example for electrical energy and for data transmission.
  • quick-connect devices can also be provided. These can be operated manually or at least partially by means of appropriately driven actuators, such as actuating cylinders.
  • the lines between supply units are preferred and tiller modules are not separated and therefore no longer have to be connected when installing the tiller.
  • each milling module can be assigned its own supply unit with a direct line connection.
  • the supporting structure can be built up compactly from steel girders, with the supporting structure being arranged exclusively at the work area.
  • a particularly efficient mode of operation of the trench wall milling device can be achieved in that the supporting structure extends along a working area in which adjacent milled slots are made.
  • the trench cutter can be moved along the supporting structure by dismantling the individual cutter modules and reassembled to form a cut trench in order to create a second or further cut in the work area. In this way, a continuous milled slot can be created in an efficient manner, such as is desired for a diaphragm or cut-off wall.
  • the support structure can be constructed individually from support elements.
  • An advantageous embodiment variant of the trench wall milling device according to the invention can be seen in the fact that the supporting structure can be moved or moved.
  • the support structure can be moved in whole or in part by means of a hoist or by means of a traversing device, such as a walking mechanism, which can also be part of the support structure.
  • Longer milled slots can also be produced with such a mobile support structure, which are produced from a large number of individual slots lying next to one another.
  • a further preferred embodiment of the invention consists in that at least one lifting unit for vertically moving the trench wall cutter is arranged on the supporting structure.
  • the lifting unit is preferably designed as a winch arrangement with a carrying cable or as a telescoping linkage.
  • the lifting unit has a corresponding lifting drive, such as a rotary drive. This can be operated electrically or hydraulically.
  • the lifting unit itself can be mounted in modular form as an easily detachable and adjustable module on the supporting structure.
  • At least one corresponding deflection roller can, for example a carrying cable from the winch arrangement of the lifting unit along an upper area of the supporting structure to the trench wall cutter and be releasably connected thereto.
  • the at least one deflection roller can be rotatably mounted on a roller carriage, which is movably mounted on the supporting structure.
  • At least one supply unit with at least one hose and/or cable reel is arranged on the supporting structure.
  • the one or more supply units can also be mounted on the supporting structure as easily detachable and displaceable modules.
  • the hoses can be designed for supplying and removing suspension or hydraulic fluid to the trench wall cutter.
  • the lines on the cable drums can be designed to transmit electrical energy, hydraulic fluid or as data lines.
  • the lifting unit and the supply unit can also be formed together on one module or one unit.
  • the support structure can be of any design. It is preferred that the support structure has vertical supports on which the at least one guide rail is held at a distance from the floor. In this way, the milling modules can be reliably slid along the support structure along one or more parallel guide rails and assembled at the work site.
  • the individual milling modules can have attachment points for attaching the lifting unit, in particular a support cable, so that the individual milling modules can be lifted into a guide slot or out of the milled slot and then moved along the supporting structure.
  • the invention also relates to a trench wall cutter, which is characterized in that it is made up of at least two cutter modules which have essentially the same height.
  • This trench wall cutter can preferably be used with the trench wall cutter device described above.
  • the trench wall cutter can also be used independently of this, in particular of the support structure described above and can also be used, for example, on conventional carrier devices.
  • the design of the individual milling modules with the same height and with a fundamental the same cross-section allows good and uniform transportability of the individual modules.
  • the height of the milling modules is not higher than twice the diameter of the milling wheels.
  • the diameter of the cutter wheels is typically between 0.5 m and 2.5 m. Accordingly, the possible height of the cutter modules is between 0.5 m and 5 m. The difference in the heights of the individual cutter modules is no more than 20%, especially not more than 10%.
  • the height of the milling module is not higher than 3 m.
  • the milling modules can thus be accommodated in a standard container or at least in a so-called high-cube container for transport purposes, which is readily suitable for road transport.
  • the compact height of the milling module according to the invention allows it to be used in tunnels, cellars or other cramped spaces.
  • one or more standard or high-cube containers can be provided as an enclosure or housing for use with the trench cutter.
  • a trench wall cutter which is characterized in that it is made up of at least two cutter modules which are mechanically detachably connected to one another, with a first cutter module with the cutter wheels being connected directly to a first supply unit independently of the second cutter module power supply is connected.
  • This trench wall cutter according to the invention can also be provided in combination with the previously described trench wall milling device or as a further development of the aforementioned trench wall cutter with essentially the same height of the cutter modules.
  • this trench cutter according to the invention is preferably independent of this.
  • An essential advantage of the trench wall cutter according to the invention is that the at least two cutter modules only have to be assembled mechanically, without a line connection between the at least two cutter modules having to be closed.
  • the first milling module with the milling wheels is directly connected to a first supply unit via a supply line, which directly from the first supply unit leads to the first milling module.
  • the at least one further milling module can be free of an energy supply.
  • the further milling module serves as a passive guide frame.
  • a preferred development of the trench wall cutter according to the invention is that the at least one second cutter module is also connected to an independent supply unit. This can be provided, for example, for actuating control elements for controlling the trench wall cutter in the trench.
  • a respective supply line from a first supply unit to a first cutter module and from a second supply unit to a second cutter module can be arranged on the opposite narrow sides of the trench wall cutter.
  • a method for cutting a cut trench in the ground with the above-described trench wall cutting device or one of the trench wall cutters is provided, in particular in which a supporting structure is arranged with a guide device, and a trench wall cutter is arranged on the supporting structure and lowered into the ground in a vertical direction ground material is milled off in a working area and the cut trench is thus formed, with the trench wall cutter being constructed from at least two cutter modules which are fed separately from one another by means of the guide device to the working area and are connected to one another at the working area to form the trench wall cutter.
  • This method can also be used to mine mineral resources that are located below a so-called micro tunnel created for this purpose.
  • a particularly advantageous method variant of the invention can be seen in the fact that at least two adjacent milled trenches are created, after the creation of a first milled trench, the trench wall cutter is withdrawn from the first milled trench, separating the cutter modules, and that to form a further cut trench, the cutter modules are moved along the guide device and reconnected to the trench wall cutter, which is then lowered into the ground while soil material is cut away.
  • this method several milled slots can be efficiently produced with good milling guidance and with relatively large milling depths, even in confined spaces.
  • the adjacent milled slots do not have to be directly adjacent to one another.
  • the at least one cut trench is filled with a settable suspension, which hardens to form the diaphragm wall.
