Definitions

  • the invention relates to a method and a device for precisely maintaining the vertical direction of excavation of a diaphragm wall using a hydraulic diaphragm wall gripper that interacts with an excavator and has an outer guide body and an inner body that receives the gripper device.
  • Diaphragm and sealing walls have become an important part of the basic structure.
  • a diaphragm wall is usually produced in individual segments. Their depth is not strictly limited in principle, but at greater depths there is a risk of “running” of diaphragm wall elements, wherein as a result of a deviation from the vertical target position in the lower wall area there are gap openings between the segments which impair the stability of the wall to be created.
  • diaphragm walls over 40 m deep requires special experience and measures during excavation, such as extensive measurements on the open slots. These are excavated without removal and therefore tend to deviate from the specified vertical direction in the case of inhomogeneous soil material.
  • the usual width dimensions of a diaphragm wall are 600-800 mm, but there are also widths of 400-1500 mm, depending on the depth and purpose of the diaphragm wall, during construction.
  • this process is time consuming and increases the construction costs, which is why the construction supervision strives to To keep diaphragm wall excavation as exactly as possible in the given direction.
  • the invention is based on the object of specifying a method and a device for precisely maintaining the vertical direction of excavation of a diaphragm wall with a diaphragm wall grab, which make it possible primarily to immediately detect a deviation from the predetermined direction of excavation, to display this at the control center of the diaphragm wall grab operation and secondly by means of a To compensate for the change in direction of the gripper.
  • One embodiment provides that a case-by-case angular deviation from the vertical is combined with a depth measuring device assigned to the diaphragm wall gripper, an assignment of the deviation and depth of the diaphragm wall is calculated therefrom and this is signaled to the control center of the diaphragm wall gripper operation.
  • a depth measuring device is assigned to the diaphragm wall gripper and means are provided with which the display of the position detector and the display of the depth measuring device can be assigned to one another.
  • the excavator operator operating the diaphragm wall grab can recognize at any time whether the diaphragm wall in the excavation is within the specified positional tolerances at the depth reached, and whether and which corrections are necessary.
  • a further embodiment provides that the swiveling device and the control device controlling it are assigned means for a higher-level manual control intervention from the excavator control center, with the aid of which a directional correction of the gripper is possible in accordance with the display of the detector.
  • a hydraulic piston / cylinder unit is articulated, which is also pivotally mounted on the frame lever assembly is in operative connection with a cam which can be moved back and forth, which engages in a U-shaped guide of the inner body and pivots this according to the position of the cam relative to the guide body from the orthogonal position into a different pivot position according to a correction angle.
  • the diaphragm wall gripper shown in FIG. 1 has a guide body 11 formed by an outer frame 12. An inner body 10 with gripper blades 1 and hydraulic actuating device 2 articulated thereon is arranged in this.
  • the inner body 10 is pivotally articulated in the guide body 11 by means of horizontal bearing pins 20 arranged in the direction of the diaphragm wall 40 transversely to the vertical course of the diaphragm wall 40.
  • Hydraulic pivoting means 30 are provided between the guide body 11 and the inner body 10.
  • detectors 25 for monitoring the vertical position of these bodies are arranged on the inner body 10 and / or on the guide body 11.
  • the detector (s) 25 are in constant operation via a signal line with a control device controlled by them for actuating the pivoting means 30.
  • a depth measuring device can be assigned to the diaphragm wall gripper (not shown), means being provided with which the display of the position detector 25 and the display of the depth measuring device can be assigned to one another. Furthermore, use can be made very advantageously of the measure that the means 30 for pivoting the inner body 10 or the control device which controls them are assigned further means for a higher-level manual control intervention from the excavator control station (not shown), with the aid of which a position correction of the inner body is associated 10 relative to the guide body 11 is possible in accordance with the position indicator of the position detector 25.
  • a piston / cylinder unit 30 is articulated, which has a lever joint arrangement 32 which is also pivotably mounted on the frame 12 and which has reciprocating pivoting movements thereon removable cams 33 is in operative connection.
  • This engages in a U-shaped guide 34 of the inner body 10 and pivots this in accordance with the position of the cam 33 relative to the guide body 11 from the orthogonal position shown in FIGS. 2 and 6 into a different pivot position corresponding to the correction angle ⁇ in the figures 3 and 4.
  • the diaphragm wall gripper hangs with its guide body 11 in a rope suspension 3.
  • the gripper according to FIG. 5 is a comparatively heavier version with a reinforced frame 12 of the outer guide body 11.
  • the inner body 10 is pivotally mounted therein in the bearing pin 20 transversely to the slot direction.
  • the hydraulic cylinders 30 are arranged differently from the hanging arrangement according to FIGS. 1-4. It is a purely manual measure at the designer's discretion. Otherwise, the two designs according to FIG. 1 and FIG. 5 are functionally the same.
  • the gripper inner body 10 is preferably formed with the angle measuring device 25 and the display of the deviation can be combined with a depth measuring device, so that the deviation can also be assigned to the corresponding slot depth and displayed on the control center.
  • the adjustment via the lever system 32 is extremely uncomplicated, requires hardly any maintenance in practice and works with great accuracy.
  • the adjusting members 30 can consist of a cylinder body with a central cylinder base, from which two piston rods can be extended independently of one another, one of which is articulated on the outer body 11 of the gripper and the other on the inner body 10 of the gripper. As FIGS. 3 and 4 show, when the piston rods are extended on both sides according to FIG. 3, they can be pivoted in one direction up to the angle ⁇ and when the piston rods are retracted on both sides, they can be pivoted in the opposite direction up to the angle ⁇ .
  • the hydraulic control of the adjusting cylinders can be designed in such a way that both an infinitely variable adjustment in both directions and a defined middle position or neutral position can be controlled as desired by the operator.
  • the hydraulic diaphragm wall gripper With its articulated arrangement, the hydraulic diaphragm wall gripper according to the invention is a very uncomplicated and robust device and enables the direction of advance of the gripper blades to be corrected either fully automatically or manually.
  • the invention ideally fulfills the task set out above.
