Definitions

  • the invention relates to a method for compacting soils by means of a deep vibrator, that of a circulating about a vertical longitudinal axis imbalance mass energized lowered into the ground and pulled out of this again.
  • deep vibrator for carrying out the method are with an elongated bomb-shaped housing with a longitudinal axis and a coaxially mounted in the housing motor-driven Rotary axis and equipped with the rotation axis circulating imbalance mass.
  • the compacting of rolling soil (gravels and sands) by means of deep vibrators in large Depths and in any thickness is tested.
  • the application of the procedure to depths of 50 meters is already running. Depths of 70 meters are desired.
  • the vibrator work is done by driving an imbalance mass in vertically suspended Vibrator housing by an electric or hydraulic motor located above is driven.
  • the deep vibrator is by screwing a pipe string, in which the supply lines run (electricity, water, hydraulic oil), for the desired depth prepared.
  • the aggregate thus formed is on an excavator or a special carrying device with a vertical broker held by a steel cable and guided.
  • the swinging and rotating suspension point is located at the top End of the tubing.
  • the deep vibrator At the lower end of the tubing is the deep vibrator means articulated a joint coupling.
  • the deep vibrator should be at the point of articulation stay calm and with the bottom Haittlerspitze a circular oscillation exercise.
  • the movement of the vibrator is thus of a cone with overhead Lace shrouded.
  • the movement of the vibrator is determined by the orbital frequency and the size of the unbalanced mass determines and does not necessarily correspond to the aforementioned ideal case.
  • Due to the rotation of the imbalance mass it comes to a reverse rotational moment on the vibrator housing, resulting in a twist the vibrator and the pipe string and thus leads to the leader.
  • twist the supply lines, which are thereby disconnected can or can tear out of their fittings.
  • This phenomenon is so far by attaching longitudinal external swords to the housing of the deep vibrator or at least by longitudinally guided outside piping only insufficiently counteracted. Incidentally, such agents increase the penetration resistance of the deep vibrator disadvantageously.
  • the compaction of the soil takes place from bottom to top. After lowering the deep vibrator on the intended final depth, he is either continuously upward pulled or in stages in increments of 20 to 100 cm, taking on each Step for a while from 20 to 60 seconds.
  • the compaction of the soil is naturally associated with a volume reduction, which is due to a funnel formation and concentric risers around the funnel on the terrain surface and at an inclination of the terrain surface further towards the funnel points.
  • it is customary with a set rotational frequency to work and control the power absorbed by the vibrator motor. This is to be avoided on the one hand unacceptable burdens, on the other Compaction steps are interrupted with only low power consumption and the deep vibrator pulled to the next level.
  • DE 26 29 485 A1, DE 29 48 403 A1 and DE 32 05 099 A1 are deep vibrators in which there are agents with which the effective imbalance mass be changed by changing the direction of rotation of the imbalance mass can.
  • the present invention has for its object to provide a method with which the mentioned malfunctions prevented and the penetration of the deep vibrator can be improved.
  • the solution to this consists in a method according to which the imbalance mass with alternating direction of rotation is driven, the direction of rotation depending is changed by the rotation of the deep vibrator against the broker.
  • the corresponding rotation can be detected with suitable contactless sensors become.
  • a suitable deep vibrator for carrying out the method is characterized in that that he a housing of purely rotationally symmetrical outer shape and a rotationally switchable drive for the imbalance mass has. With this purely rotationally symmetric Outside shape of the deep vibrator receives an improved penetration.
  • monitoring means for the twist angle of the deep vibrator opposite the broker are provided and a preferably automated reversal the damage-free Operation secures. Changes with the change of the direction of rotation of the imbalance mass the direction of rotation of the return torque, so that the twist occurred is canceled again and the then entering twist in the opposite direction in itself repeatedly controlled and limited.
  • the effective imbalance mass remains unchanged.
  • FIG. 1 shows a torpedo-shaped deep vibrator 11 whose cross-section is pure is circular cylindrical and which reveals a conical tip 12. At the upper end a movable coupling 13 is provided, to which a linkage section 14 followed.
  • FIG. 2 a deep vibrator 21 according to the prior art is shown in comparison to FIG. in addition to the matching features of a conical tip 22, a coupling 23 and a linkage section 24, lateral cable guides 25, 26 and overlying radially projecting swords 27, 28 can be seen, the Counteract a twisting of the vibrator in the ground.
  • the swords 27, 28 have the shape of radially projecting fins.
