Definitions

  • the object of the invention is to provide a drilling auger and a method for creating a foundation element in the ground with a auger, which allow the production of particularly high quality foundation columns in a particularly reliable and robust design of the auger.
  • a first aspect of the invention can be used in a locking device be seen with the one in an unlocked state the locking device largely unhindered possible Material flow in Wendelgang purposefully blocked, i. largely can be prevented or at least disabled.
  • a material transport along the Bohrschnecke selectively influenced in various stages of the process become. This additional option of process control allows the production of high quality high quality foundation elements.
  • the at least one helix is suitable according to the invention helically formed. Under the helical turn can according to the invention the space to be understood, that between the at least a helix, the drill pipe and a cylindrical enveloping the at least one helix is formed.
  • a structurally particularly simple locking device created. If a locking device with at least a closure element is used, may alternatively or additionally an adjusting mechanism may be provided which the displacement of the pipe parts against each other in an adjusting movement of the closure element from the opening position in the lock position and vice versa converted.
  • the locking device so is formed that the helical gear when pushed together Pipe parts is locked and when pushed apart pipe parts is unlocked.
  • the pipe parts shifted depending on the load against each other are, i. that the pipe parts when advancing the drill pipe in the soil due to the axial force acting on the drill pipe be pushed together.
  • a return device for example a return spring, be provided, which the pipe parts at decreasing Overload or axial force again shifts apart.
  • a sliding frame drive be provided.
  • the Wendelgang when pulling the Bohrschnecke the Wendelgang is unlocked and the auger in particular, further rotated in the downward conveying direction becomes.
  • unlocking the soil supplement material can now conveyed along the entire spiral path to the drill tip be filled, and there fill a cavity, which when pulling the Drill pipe is created.
  • the soil additive material only due to the effect of gravity at rotational moderate standstill of the auger in the To promote cavity.
  • the auger also turned in the downward direction when pulling becomes.
  • a erfindungseffleßes drill has an inventive Bohrschnecke on, as well as a rotary drive for rotating the auger, at least in the downward conveying direction and a feed drive for axially advancing the drill pipe into the ground.
  • the drill can in particular for carrying out the invention Serve the method.
  • the first part helix protrudes 51 in the helical turn 6 of the second sub-coil 52 into it.
