Definitions

  • the invention relates to a diaphragm wall device for creating a slit in the ground, with a base frame which extends in a longitudinal direction, at least one soil removal device which is arranged at a lower end region of the base frame, a holding device at an upper end region of the diaphragm wall device, a bracing device with at least two opposing clamping elements which can be moved laterally, transversely to the longitudinal direction, and at least one adjusting element by means of which the clamping elements can be extended laterally in order to brace at least part of the diaphragm wall device in the slit, an intermediate frame which is slidably mounted along the base frame in a lower region of the base frame and on which the bracing device with the at least two clamping elements and the at least one adjusting element is arranged, and a pressure device by means of which a pressure force can be applied to the at least one soil removal device, wherein the pressure device is arranged between the intermediate frame and the base frame, according to the preamble of claim 1.
  • the invention further relates to a method for creating a slit in the ground with such a slit wall device according to the preamble of claim 13.
  • Such diaphragm wall machines are known in particular as so-called diaphragm wall cutters with cutting wheels as soil removal devices. These are usually suspended from a carrier device via a support cable. At the upper end of the base frame is A holding device for a support cable, a support rod or similar is arranged. This means that the maximum pressure force on the ground is limited by the weight of the diaphragm wall device.
  • a trench wall cutter is known in which longitudinally and transversely movable clamping plates are provided on a cutter frame, which together with transversely directed clamping cylinders form a unit.
  • the clamping cylinders are each supported on the opposite clamping plates.
  • the unit formed from clamping plates and clamping cylinders is mounted so that it can move in the transverse direction relative to a base frame of the cutter, so that the unit is overall floatingly mounted.
  • this floating mounting prevents the position of the base frame suspended from a support cable from shifting.
  • an arrangement of vertically directed pressure cylinders is provided below the unit with the clamping plates.
  • the EP 0 593 355 A1 teaches a similar floating support of clamping plates in a transverse direction.
  • the clamping plates are arranged on a common piston and can therefore be moved together in the transverse direction.
  • a trench cutter with a base frame and a lower vertically movable tool carrier part with the cutting wheels is from the EP 0 811 724 B1
  • the base frame which is held by a support cable, can be clamped in the milling slot using transverse clamping elements, while the milling wheels can be moved downwards.
  • a trench wall cutter is known in which transversely directed adjusting elements are also supported on the one hand on a first clamping plate and on the other hand on a second opposite clamping plate.
  • additional clamping cylinders are provided which are directed diagonally downwards and can be used to additionally clamp the individual clamping plates against an intermediate frame.
  • the intermediate frame is guided on a base frame of the cutter so that it can be moved in the direction of advance.
  • a tensile force can be applied to the cutter wheels via upper diagonally directed pressure cylinders to apply an additional propulsive force.
  • a holding device for a support cable is attached to the base frame.
  • the DE 38 05 868 shows a diaphragm wall device according to the preamble of claim 1.
  • This diaphragm wall device has a relatively large and massive "intermediate frame” at the upper end of a "base frame”.
  • This "intermediate frame” with its large mass cannot contribute any (weight) force in the direction of advance when it is braced. This mass is therefore ineffective and inefficient when it is braced.
  • the invention is based on the object of specifying a diaphragm wall device and a method with which a slit in the ground can be efficiently created with a compact design of the diaphragm wall device.
  • the diaphragm wall device according to the invention is characterized in that the intermediate frame is mounted so as to be displaceable along the base frame in a lower area of the base frame and that the holding device is firmly connected to the intermediate frame via one or more longitudinal beams which extend along the base frame.
  • a first aspect of the invention consists in attaching the holding device for holding the diaphragm wall device not directly to the base frame with the soil removal device, but to the intermediate frame with the bracing device.
  • the base frame with the soil removal device is thus displaceable in the advance direction not only relative to the intermediate frame with the bracing device, but also relative to the holding device. This allows the advance of the Soil removal equipment, in particular milling wheels, can be moved on the base frame without the holding device having to be adjusted.
  • the holding device is intended to be connected in particular to a support cable or a support rod on a carrier device.
  • the soil removal device can thus be moved without a support cable or the support rod having to be adjusted on the carrier device. This simplifies the control of the feed movement and a desired pressure force. This can now be done in particular by controlling the pressure device alone.
  • the intermediate frame with the bracing device is arranged in a lower area of the diaphragm wall device.
  • the diaphragm wall device can be braced to the walls of a previously formed guide slot.
  • the base frame is guided on the intermediate frame in a substantially vertical direction and a desired pressure force can be applied to the soil removal device at an early stage.
  • the holding device is firmly connected to the intermediate frame via one or more longitudinal beams which extend along the base frame.
  • a single longitudinal beam can be sufficient, via which the intermediate frame arranged in a lower area is firmly connected to the holding device in the upper area of the diaphragm wall device.
  • two or more, in particular four, longitudinal beams are preferably arranged, preferably along the outer sides of the base frame.
  • the longitudinal beams can each be designed in particular as double-T beams.
  • corresponding channel-shaped recesses are provided along the base frame for the longitudinal beams, so that they do not protrude beyond the outer dimensions of the base frame.
  • a particularly robust design of the diaphragm wall device is achieved by attaching the holding device to a cross member which is arranged in an upper area of the base frame.
  • the holding device which can be a connecting element or a coupling element for attaching a support cable or support rod, can be arranged centrally and/or along a longitudinal axis of the Diaphragm wall device. With this central arrangement, a good connection to the external longitudinal beams can be made via at least one cross beam.
  • a further preferred embodiment of the invention consists in that the tensioning device has at least two adjusting elements arranged perpendicular to the longitudinal direction, wherein at least one first adjusting element is mounted on the one hand on the intermediate frame and on the other hand on a first clamping element and at least one second adjusting element is mounted on the one hand on the intermediate frame and on the other hand on a second clamping element which is arranged opposite the first clamping element and that the first adjusting elements and the second adjusting elements can be extended perpendicular to the longitudinal direction.
  • Each plate-shaped tensioning element can be assigned at least one individual adjusting element, in particular a tensioning cylinder, which is supported on the one hand on the respective tensioning element and on the other hand on the intermediate frame.
  • the adjusting elements are directed transversely to the longitudinal or advance direction of the diaphragm wall device. This allows the individual tensioning elements to be adjusted individually in relation to the intermediate frame. In addition, a clear separation is achieved between the transverse forces and the longitudinal forces for pressing the diaphragm wall device, which overall contributes to a compact structure and efficient operation.
  • opposing tensioning elements can also be attached to a common holder or adjusting device, with the holder being mounted on the base frame in a floating manner so that it can be moved in a transverse and/or longitudinal direction.
  • a compact structure is further promoted according to a further development of the invention in that the intermediate frame is slidably mounted on the base frame on a bearing section which has a reduced cross-section compared to the base frame, forming at least one free space, and in that at least one receptacle for receiving at least part of the actuating element is formed on the slidable intermediate frame, the receptacle being arranged in the free space formed.
  • actuating elements which are actuators or linear drives, in particular clamping cylinders, preferably hydraulic cylinders.
  • two lateral free spaces are formed on the bearing section and that two receptacles for adjusting elements are formed on the intermediate frame.
  • the adjusting elements for the opposite clamping elements can thus be arranged in the two lateral receptacles. At least one first adjusting element and at least one second adjusting element for the opposite clamping elements are provided in each lateral receptacle.
  • the holder can be open and designed with only one base plate to which the respective adjusting element is attached and supported. Opposite adjusting elements can support each other on the same base plate, whereby the transverse forces on the base plate largely compensate for each other.
  • the at least one holder on the intermediate frame is designed in a box-like manner and has at least one first adjusting element and at least one second adjusting element.
  • the box-like holder has side walls which face the respective plate-shaped clamping elements, whereby the side walls each have at least one passage for at least one of the adjusting elements and at least one support area for attaching the adjusting element facing the opposite clamping element.
  • first adjusting elements and several second adjusting elements are arranged in a receptacle of the intermediate frame.
  • two first adjusting elements and two second adjusting elements are arranged in each receptacle, which are each directed in opposite directions transverse to the longitudinal direction.
  • a control is provided by which the first actuating elements and the second actuating elements can be extended in a defined manner.
  • the actuating elements can be extended evenly so that the individual clamping elements come to rest on the surrounding walls of the slot as simultaneously as possible, so that no change in the position of the base frame of the slot wall device is caused in the slot.
  • control is designed to initially extend the at least one first actuating element and the at least one second actuating element with a first low pressure force until the clamping elements rest against the surrounding floor, and then to apply a high pressure force for clamping.
  • the high clamping force required for clamping is only initiated by the control device in particular when no further extension movement is detected on the actuating elements when the first adjustment force is applied. This can be interpreted as an indication that the respective clamping elements have come into a clamping position to rest against the respective adjacent wall when they are extended.
  • control device is connected to sensors by which a pressing force and/or an extended position of the actuating elements can be detected.
  • the pressing force can be detected at the individual actuating elements or centrally for groups of actuating elements or for all actuating elements as a whole.
  • a further preferred embodiment of the invention is that the pressure device is arranged above the bracing device and has at least one, preferably several pressure cylinders.
  • the bracing device can be arranged very close to the soil removal device. This allows the diaphragm wall device to be braced very early in the slot formed, so that additional pressure forces can be applied to the soil removal device at an early stage of a foundation process.
  • the pressure cylinder(s) are designed in such a way that they exert a tensile force on the base frame in order to apply the pressure force. By contracting the at least one pressure cylinder, the base frame and thus the soil removal device can be pulled downwards with a desired force.
  • each pressure cylinder is attached to the base frame on the one hand and to the intermediate frame or a clamping element on the other. This allows a direct flow of force when pressing between the longitudinal movable base frame and the fixed intermediate frame or the respective clamping element.
  • the at least one pressure cylinder can be arranged parallel to the longitudinal direction of the diaphragm wall device.
  • a particularly compact arrangement is obtained according to an embodiment of the invention in that the pressure cylinders are arranged inclined to the vertical, whereby the base frame with the soil removal device can be pressed downwards relative to the braced intermediate frame by actuating the pressure cylinders.
  • the diaphragm wall device is designed as a diaphragm wall cutter, wherein the soil removal device has at least one cutting wheel.
  • the soil removal device has at least one cutting wheel.
  • two pairs of driven cutting wheels with mutually parallel cutting wheel axes are arranged at the lower end of the base frame as a soil removal device.
  • An alternative embodiment of the invention is a diaphragm wall device which is designed as a diaphragm wall grab, wherein the soil removal device has grab blades.
  • a particularly high removal rate can be achieved by the bracing device designed according to the invention, particularly when inserting and closing the grab blades in the soil.
  • the invention further comprises a method for creating a slot in the ground using the previously described diaphragm wall device according to the invention, the method being characterized in that the diaphragm wall device is held at an upper end region by means of a holding device, that soil is removed by means of at least one soil removal device, which is arranged at a lower end region of the base frame, to form the slot, that at least two opposing clamping elements are extended laterally by means of a bracing device by at least two adjusting elements directed perpendicular to the longitudinal direction, wherein at least a part of the diaphragm wall device is braced in the slot, that a pressing force is applied to the at least one soil removal device by means of a pressing device, that the clamping device with the at least two clamping elements and the adjusting elements is arranged on an intermediate frame to which the holding device is attached and the The base frame is mounted so as to be displaceable relative to the intermediate frame and the holding device, the intermediate frame is braced and fixed relative to the ground by the brac
