Definitions

  • the invention relates to a vibrator arrangement for producing stuffing columns and a method for operating such a vibrator arrangement.
  • Stuffing pillars are material pillars that are placed in the ground and used in construction to improve the soil properties for subsequent development.
  • vibrator arrangements can be used which, with the help of vibrations, partially penetrate the ground and create a borehole in the ground. Then material such as dry concrete, recycled concrete, rubble, sand, gravel or a mixture thereof is fed into the borehole via the vibrator arrangement and the material is then compacted. By repeating this process several times, the stuffing column made of material is filled piece by piece up to the surface of the ground.
  • the time required for the production of stuffing columns is largely determined by the time needed to load the vibrator arrangement and to fill the stuffing columns.
  • the object on which the invention is based can thus be seen in creating an improved vibrator arrangement which allows more material to be directed into the borehole per unit of time.
  • An exemplary vibrator arrangement has a silo tube with a longitudinal axis and a first end and a second end.
  • the vibrator arrangement can have a vibrator unit which is mechanically coupled to the silo tube, as well as a filling arrangement which opens into the silo tube at the first end.

  • the filling arrangement 150 has two chambers 151 and 152.
  • the number of chambers can be selected depending on the number of channels in the silo tube 110.

  • the channels 123 and 124 are separated from one another in a gas-tight manner and can each be supplied with compressed air by a separate compressor and independently of one another. This ensures that both channels 123 and 124 can be supplied with the same pressure and the same volume flow of compressed air. A clogging of an individual channel can thus be reliably prevented.
  • the pressure and the volume flow of the compressed air can be in both channels 123 and 124 be different.

  • a valve can be used that distributes the pressure and the volume flow of the compressed air to both channels, in particular evenly. It should be prevented that significantly more compressed air escapes through one of the two channels 123 or 124 than through the other channel 123 or 124.
  • the vibrator arrangement described can be used for the production of stuffing columns.
  • the vibrator arrangement with the filling arrangement 150 can be suspended from a crane or other lifting device (not shown).
  • the vibrator arrangement can then be moved to the desired position on the stuffing column by crane.
  • the vibrator unit 140 can be switched on and the second end 112 of the silo tube 110 can be brought into contact with the ground. Under the influence of the weight of the vibrator arrangement and the vibrations generated by the vibrator unit 140, the silo tube 110 of the vibrator arrangement penetrates into the ground to a predefined depth and thereby creates a borehole (not shown).
  • water can be blown out at the second end 112 of the silo pipe 110. This measure cools the second end 112 of the silo tube 110 and keeps the borehole free.
  • the water can also flow off between the silo pipe 110 and the ground and from the second end 112 of the silo pipe 110 in the direction of the earth's surface. As a result, the friction between the silo pipe 110 and the ground can be reduced.

  • Dilatancy is understood to mean an increase in volume and thus an increase in the viscosity of a granulate such as a material.
  • the dilatancy occurs in densely packed granular material on which large shear forces act. This is the case insofar as the material is only blown out of the channels 121 and 122 via the upper compressed air supply. The result is a blockage of the channels 121 and 122 in the area of the second end 112 of the silo tube 110.
  • the additional use of the injection line ensures that the material can be discharged unhindered from the channels 121 and 122 into the borehole.

  • the silo tube 810 is constantly moved up and down via the rope 811, while the supply unit 820 can be moved independently of this via the rope 821 relative to the silo tube 810.
  • the supply unit 820 is lowered in the direction of the subsurface 800. Once the supply unit 820 has reached the ground 800, the movement of the rope 821 is stopped and the supply unit 820 stands on the ground 800 solely by its own weight. The supply unit 820 can be filled with new material.

This can be understood to mean that the ropes 821 are pulled up in the direction of the support frame 830 while the silo tube 810 moves in the direction of the subsurface 800. The same also applies vice versa. If the silo tube 810 moves out of the borehole 801, the cables 821 are unrolled from the support frame in the direction of the ground. In this state, the cable winch on the crane or excavator always moves the cable 811 against the direction of movement of the cable 821.

  • the supply unit 820 has arrived at its predefined filling position on the silo tube 810 or on the filling arrangement attached to it.
  • the movement of the rope 821 is stopped and the supply unit 820 then moves synchronously with the silo tube 810. This results in synchronism between the silo tube 810 and the supply unit 820, which allows the material from the supply unit 820 to be poured into the silo tube 810 in a process-reliable manner.
  • the silo tube 810 is also moved up and down in the borehole during the transfer.
