Definitions

  • the invention relates to a trench cutter according to the preamble of claim 1 and a method for milling a trench wall according to the preamble of claim 10.
  • a milling frame with cutting wheels is lowered onto the floor on a carrying device.
  • the rotary movement of the milling wheels removes the soil below the milling frame and creates a diaphragm wall by repeating this process in horizontally spaced positions.
  • the milling direction of the milling frame is determined vertically downwards by its own weight. As a result, only vertical diaphragm walls can be produced with the known trench wall cutter.
  • the milling direction also points away from the vertical if the distribution of the rock layers in the soil is not homogeneous. If the milling frame encounters thicker rock layers on one side, it will usually move to the other side.
  • FR-A 25 73 475 describes a trench wall cutter for the extraction of uranium ore, which is used in excavation tunnels above an ore deposit and mines the ore vertically downwards.
  • the trench wall cutter has a rectangular milling frame and guide plates in the area of the vertical walls, which are to serve as control elements for the most exact excavation possible and for efficient mining of the ore deposit.
  • each guide plate can be adjusted outwards parallel to the vertical wall. The inclination of the milling frame and the diaphragm wall is not measured or checked.
  • the invention has for its object to provide a trench cutter and a method for milling a trench wall, which enable a controllable and controllable production of trench walls with an exactly predetermined direction.
  • control elements are preferably designed as control flaps which are arranged on the vertical side walls of the milling frame.
  • the control flaps can be operated via a hydraulic system with a hydraulic cylinder which is arranged between the milling frame and the control flap.
  • the control flaps are elongated and arranged vertically on the sides of the milling frame running parallel to the direction of advance.
  • a control flap is arranged on the broad sides of the milling frame in the corner regions thereof. Due to the vertical alignment of the control flaps, these can be pretensioned against the diaphragm wall either at the lower end or at the upper end, as a result of which a torque is generated in the predetermined direction on the milling frame.
  • the hydraulic cylinders for driving the control flaps are provided with a displacement sensor and a pressure switch, the displacement sensor on the one hand showing how far the control flap protrudes from the outer contour of the milling frame, which in turn allows conclusions to be drawn about the inclination of the milling frame and the diaphragm wall.
  • the measured values are fed to a control device, which in turn controls the drives for the control flaps of the milling frame.
  • An inclinometer is arranged in the milling frame, the output signal of which is evaluated for direction correction. The evaluation in turn takes place in the control device and is used to control the drives for the control flaps.
  • Directional corrections when milling the diaphragm wall can be carried out in a simple manner if the milling frame is clamped into place by lowering the slot by actuating the control elements.
  • the inclination of the milling frame is then measured with the inclinometer on the milling frame. This process is repeated at different depths with a distance of at least 1 m. The inclination of the slot can be calculated from these measured values.
  • the control device can determine the data for the actuation of the control flaps to determine the further milling direction from the calculated inclination value.
  • the further milling process is thus carried out with a changed milling direction, which is obtained in that the control elements clamp the milling frame in the slot in a certain direction.
  • the hydraulic cylinders or pistons for actuating the control flaps are each attached to the milling frame or the control flap via eyes.
  • the hydraulic cylinder is also mounted in a plastic sleeve, which means that the hydraulic system only absorbs forces in the axial direction and is relieved of transverse forces.
  • the trench wall cutter 10 consists of a rail-guided carriage 12 with an extension arm 14, on which a milling frame 18 is suspended via a supporting cable 16. On the milling frame 18 there are two pairs of milling wheels 20 which are driven by two hydraulic motors 22. Lateral control of the Milling frame 18 in the slot 24 is realized by elongated control flaps 26, 28 which are arranged on the vertical broad or narrow sides of the milling frame 18.
  • the control flaps 26, 28 are actuated via two hydraulic lines 30 and a valve arrangement arranged in the milling frame.
  • FIG. 2 shows a partially cut section of the milling frame 18 from FIG. 1. Identical parts are provided with identical reference numbers.
  • the control flap 26 is in a first non-extended position within the outer contour 32 of the milling frame 18. At its upper and lower ends, the control flap 26 is fastened to the milling frame 18 with a hydraulic cylinder 34, 36 in each case.
  • the control flap 26 is articulated to the hydraulic cylinders 34, 36 via eyes 38. As a result, no bending forces act on the hydraulic cylinders if only the lower or upper end of the control flap 26 is extended by corresponding actuation of the respective hydraulic cylinder 34, 36.
  • both hydraulic cylinders 34, 36 are extended, the control flap 26 can be moved outward parallel to the outer contour 32 of the milling frame 18 and thus clamp the milling frame 18 in the diaphragm wall 24 over a large area.
  • the actuation of the hydraulic cylinders 34, 36 is monitored via displacement transducers 40, which emit an output signal that provides information about how far the hydraulic cylinders 34, 36 have been extended.
  • pressure switches (not shown) are also arranged, which respond when the control flap 26 abuts the diaphragm wall.
  • the inclination of the diaphragm wall and / or the inclination of the milling frame can be determined and used to control the further advance.
  • the milling frame 18 is preferably fixed in the slot 24 by extending the control flaps 26, 28 and the inclination is measured. This process is repeated at different depths of the slot, with a distance of at least 1 m between the measuring points.
  • the inclination of the slot is calculated from the measured values of the inclinometer and / or the displacement transducers 40 thus obtained.
  • the direction correction is carried out either manually or automatically by extending the corresponding control flaps or the corresponding control flap.
  • the extension of the control flap can be varied by extending only the upper end or only the lower end or the entire control flap.
  • control flaps 26 are provided for jamming the milling frame 18 transversely to the plane of the diaphragm wall 24, while the control flaps 28 are provided for fixing to an end wall, that is to say in the plane of the diaphragm wall. These control flaps 28 are therefore primarily relevant when the milling frame is lowered into the ground for the first time. The control flaps 26, 28 can thus be used to correct the direction of the milling frame in the entire horizontal plane.
