Definitions

  • the invention relates to a method according to the preamble of claim 1 and a device for carrying it out.
  • gaps can occur between the successive wall sections or tracks, the presence of which is not ascertained or only after completion of the narrow wall due to the leakage of water or other liquids can.
  • US-A-4249936 already shows a device of this type, in which an elongated vibrating bar with a double-T cross-section and a plurality of mortar supply nozzles attached to it has a rib projecting to the rear which, when the vibrating bar is lowered again into the ground, in each case in the at first pulling out the vibrating beam immerses the manufactured part of the narrow wall and is to guarantee a seamless connection of the successively manufactured sections of the narrow wall.
  • the entire vibrating bar can only be set into a uniform vibrating motion with great effort.
  • the invention is intended to provide a method and a device by which a tight mutual connection of the successively manufactured sections of a narrow wall or a thicker diaphragm wall and between the individual tracks of each wall section is reliably ensured.
  • the vibrating movement of this rearmost vibrating tube only takes place as long as it does not leave the borehole laterally a very low resistance.
  • This low resistance to the vibrating movement corresponds to a relatively small current consumption of the associated vibrating motor.
  • the current intensity of the current absorbed by the vibrating motor increases suddenly.
  • the current consumption is then brought back to a minimum value, which ensures that a tight connection of the wall section produced by the two front vibrating tubes and the guide swords is achieved on the previously produced wall section.
  • the seamless connection of the individual sheets also ensures tightness within each section.
  • the method according to the invention can already be carried out with only two vibrating tubes carried by a leader.
  • the use of three vibrating tubes is preferred, but the invention is not restricted to this, but can also use more parallel vibrating tubes on a common leader without significant disadvantages for the simultaneous creation of longer narrow or diaphragm wall sections.
  • Maintaining the current consumption at a minimum value can be done either by visually monitoring a current measuring device at the driver's seat of the vehicle carrying the leader or crane and triggering mechanical correction devices, or according to claim 2 by automatic monitoring by means of control devices which are known per se to the person skilled in the art, e.g. B. a device according to claim 7, are made.
  • the discharge of injection material from the rearmost vibrating tube when pulling is usually regulated automatically by the prevailing pressure conditions.
  • the outlet of injection material can also be blocked at least temporarily, for example towards the upper end of the drawing process.
  • the monitoring of the current consumption on the motor of the rearmost vibrating tube can also be carried out by registration using a recorder, e.g. of an ampere depth recorder.
  • a ram with at least two, preferably three vibrating tubes is proposed according to claim 6, with guide swords which are expediently provided only in the spaces between two vibrating tubes with their lateral ends
  • Recording of the differential vibration of the vibrators are connected either by a flexible rubber-metal sleeve or by loose interlocking, and the rearmost vibrating tube in the direction of creation of the narrow or diaphragm wall is provided with a measuring device for the current consumption of the associated vibrating motor.
  • the rearmost vibrating tube in the direction of creation of the narrow or diaphragm wall is provided with a measuring device for the current consumption of the associated vibrating motor.
  • the front vibrating tube has only one backwards sword and the rear one only has a guide sword pointing forwards.
  • the overlap ensures that the pressed injection materials are closed without gaps.
  • the lateral ends or edges can interlock according to claim 8 with a type of tongue and groove, so that the vibrating tubes are always held approximately in one plane.
  • the interlocking guide swords can also be welded to one another, so that the direction of the ram has to be corrected always be transferred equally to all parts of the same.
  • the guide swords While it is sufficient for certain types of soil if the guide swords create cavities which are then also filled by the injection material emerging from the vibrating pipes, in special cases the guide swords can also be connected to the feed devices for the injection material and have nozzles for introducing the injection material .
  • the overall effect of the vibrating hammer can be significantly improved when carrying out the method according to the invention if the diameter of a vibrating tube is in the range of approximately 200-250 mm, preferably 230 mm, the vibrating amplitude is in the range of approximately 7-8 mm and the vibrating frequency is kept in the range of about 3600 - 4000 U / min.
  • the ram generally designated 10, is carried by a leader 12, which in a manner not shown hangs on a cross mast 14 of a crane 16 with a cab 18.
  • the crane 16 moves forward on the surface 20 of the soil 22 step by step in the working direction 24.
  • the ram 10 has a frame 26 which can be displaced in the vertical direction on the leader 12 and which carries three parallel vibrating tubes I, II, III.
  • Each vibrating tube has feed devices for injection material, which are known per se, and vibrating motors with their electrical feed lines.
  • the lower ends of the vibrating tubes I, II, III are conical in a manner known per se.
  • the middle vibrating tube II has a forward and rearward facing guide sword 28 near its lower end, while the front vibrating tube III carries only a rearward facing guide blade 30 and the rear vibrating tube I carries only a forward facing guide sword 32.
  • the lateral ends 34 of the guide swords 30 and 32 engage in corresponding grooves 36 of the guide swords 28 and are welded to them or loosely led the same.
  • the time of the method recorded in FIG. 1 shows the ram 10 during the penetration phase in the direction of the arrow 38.
  • the three paths indicated by 40 of the narrow wall previously created, generally designated 42 were drilled and through the three vibrating tubes About supply lines and nozzles, not shown, near the lower ends of the vibrating tubes I, II, III and guide swords 28, 30 32 with injection material backfilled, while two intermediate tracks 44 were drilled by guide swords 28, 30, 32 and filled with injection material.
  • the crane 16 was moved so far forward in the working direction 24 that the rearmost ram I is above the foremost track 40. Then the penetration movement of the ram 10 begins in the direction of arrow 38.
  • the front vibrating tubes II and III penetrate into the soil 22 with their guide swords, while the rearmost vibrating tube I is lowered into the foremost path of the still soft injection material.
  • the associated guiding sword 32 also partially penetrates into soil 22.
  • the current consumption at the associated vibrating motor is low. However, it immediately rises sharply when the vibrating tube I moves out of the web 40 of the still soft injection material and gets into dense soil 22.
  • the direction of the ram 10 is immediately corrected so that the rearmost vibrating tube I is lowered again into soft injection material. In this way, a perfect overlap of the adjacent sections of the narrow wall 42 can always be guaranteed.
