Definitions

  • the invention relates to a device for producing Pillars of material in the ground, in particular stuffing columns or Dräns, according to the preamble of claim 1.
  • a comparable device is basically from DE 22 60 473 C2 became known. It has a lifting device like a mobile crane.
  • the lifting device is used to manipulate a conveyor system to build Material columns, which consist of a deep vibrator or a different type of jacking head and a material feed pipe consists. With the help of the head, a hole is first made brought down and then filled with material.
  • the structure can be designed differently be. For the production of drains, the material is filled in loosely, so that comparatively large pore spaces between the Material grains remain. On the other hand, a strong one compacted structure can be achieved in which the material is heavily stuffed with lateral compression.
  • the filling material is fed from above over the material delivery pipe fed, the conveyor system as a whole, i.e. H. including the material feed pipe, under positive pressure can be set to prevent water from entering or floor material in the by the sinking unit, consisting from the material feed pipe and the deep vibrator To prevent cavity, and on the other hand leakage of Ensure underground material.
  • the filling material is batched using a container Conveyor system fed by adding at the top of the material feed pipe.
  • a cable winch is provided, which in a conventional manner a cantilever of the lifting device is attached. So that is it is possible to put the container on the ground on the one hand, in order to fill it with ready material. On the other hand it can reach the upper end of the material feed pipe be raised in order to load this with filling material.
  • the above described device is a so-called instead of the crane Leader provided. It is a vertical one Mast on which a slide can be moved on rails is stored. The sledge is used for manipulation of the conveyor system according to the above specification.
  • the leader continues to carry one at the top a winch provided cantilever for manipulating the Container. Leader and cantilevers thus form a constructive Unit.
  • the invention was therefore based on the problem of a device to improve the type mentioned in such a way that the Disadvantages described above no longer occur. Especially should be achieved the loading process too optimize to minimize unwanted downtime to keep as possible.
  • the invention is based on the idea of moving the container with that of the conveyor system at least for the duration of the To synchronize the loading process. This is it possible to close the container without stopping the vibrator empty. Downtimes due to the loading process no longer occur, so that the effectiveness in manufacturing the material columns can increase significantly.
  • the cable winch is preferably designed so that it is force-free or can be switched almost power-free as long as the Container is placed on the floor. This operating state enables the container to be filled without removing it Uncoupling the rope. The rope hangs during this time loose or with little pretensioning force on the container, even if the carriage is moved up.
  • the cable winch is back engaged and lifts the container.
  • the container is preferably guided on the leader, for example about rollers that run on rails. Unintentional Pendulum movements of the container are therefore reliable avoided.
  • synchronization can be according to another preferred one
  • Variant can be achieved in that on the carriage or a stop is attached to the conveyor system against which the container is driven after filling with material and there is held for the duration of the feeding of the conveyor system.
  • the cable winch is equipped with a limitation device the tensile force, for example in the form of a slip clutch Mistake.
  • the tractive force is chosen so that it on the one hand container filled with material The up and down movement of the Carriage or the conveyor system still possible.
  • This solution represents an inexpensive variant with which the leader described at the beginning with a fixed cantilever can be converted.
  • this one Solution ensures that the rope when docked to the conveyor system Container is always kept under tension.
  • Another alternative is fixed Cable winch to provide a control device based on this acts and the synchronization of the container with the carriage or the conveyor system.
  • the container filled with material is raised and during the Duration of loading moved up and down synchronously with the conveyor system.
  • Care must be taken to ensure that the rules regulate the Compliance with the relative position of the container and conveyor system or Adheres to the carriage within a certain tolerance range, which essentially by the design of the container in Area of the chute and the corresponding intake opening of the conveyor system is specified and between 0.1m and 0.3m lies.
  • This alternative is also special as a retrofit option for existing systems with a fixed leader and on it attached cantilever beam.
  • a loading lock arranged, which allows the conveyor system even then to be loaded without downtime if the above described Process with overpressure in the range of Material outlet works on the vibrator tip, practiced becomes.
  • the loading lock ensures that the below in Conveying pipe prevailing overpressure does not have to be reduced to Refill material. Rather, the feed lock for the duration of the loading process in relation to the conveyor pipe sealed pressure-tight. Once the container is complete is emptied, the loading lock is opposite the The environment is sealed pressure-tight and the transition to the delivery pipe can be opened. Depending on the remaining Air volume in the feed lock occurs when the Transition to the delivery pipe only a small pressure drop on, thanks to the compressed air supply to the delivery pipe can be caught.
  • one is from Pressure chamber or delivery pipe independent compressed air supply for the loading lock is provided. So that before opening the transition to the conveyor pipe in the feed lock Overpressure can be built up in accordance with the prevailing pressure in the pressure space below. Consequently the pressure built up in the delivery pipe remains at the desired level Level.
  • the loading lock is preferably designed as a tank, its capacity at least the volume of the container corresponds. This makes it possible to fill in the container one pass. It can be particularly advantageous if the tank has a capacity that can accommodate multiple batches. It can be used as a buffer serve for the filling material, whereby the loading process practically completely from the shaking process decouples. Downtimes are also certain then to avoid if the supply of filler material over the Containers should experience an unforeseen disturbance.
  • a device 1 is shown, the is placed on the floor 100 and one not closer here shown material column, for example in the form of a Darning column or a drain.
  • the device 1 has a mobile device carrier 10 which takes up all components.
  • a leader 12 attached on the equipment rack 10 .
  • the leader has not shown here Guide rails for a carriage 14, which with respect to the leader 12 can be moved along its entire extent is led.
  • the carriage 14 takes a known sinking unit with deep vibrator 16 and material feed pipe 17 and serves to manipulate them.
  • a bellows 20 is attached to the upper end of the slide 14, which carries a winch 22 at the end. With the help of A winch 22 is manipulated by a container 26 Rope 24 is held. Alternatively, the cable winch 22 can also be used in the Container 26 may be integrated.
  • Another special feature of the invention lies in the implementation the double-acting feed lock 18, which then is used when the structure of the material column under Overpressure occurs.
  • the deep vibrator 16 continuously, even during material injection, at the Tip of the material feed pipe 17 overpressure, which by a Compressed air supply, not shown here, built is maintained.
  • the feed lock 18 is designed so that it on the one hand opposite the material feed pipe 17 with a lock door 21 and on the other hand in relation to the surrounding area a loading opening 19 can be closed in a pressure-tight manner can.
  • the lock door 21 is sealed, so that the structure of the material column while maintaining the desired overpressure can expire.
  • the loading opening 19 is closed in a pressure-tight manner and then the lock door 21 to the deep vibrator 16 opened so that the material can pass through.
  • the material is maintained while maintaining the Pressure levels in the material delivery tube 17 passed through, one Interruption of operations or a mix-up of that Material delivery pipe 17 penetrates soil with gravel not instead.
  • An additional compressed air supply, not shown here for the feed lock 18 allows one of the deep vibrators 16 independent pressure build-up, so that the transition between Feeding lock 18 and deep vibrator 16 without pressure difference can be opened. The otherwise occurring also does not apply short-term pressure drop caused by pressure equalization occurs with the feed chamber 18.
  • the capacity of the feed lock can be increased 18 larger than the funding volume of the container 26, so that a kind of intermediate storage tank is created, which further decouples material supply and Column structure enables.
  • Loading lock 18 saves about 3 to 5 minutes per column of material. This corresponds to a relative one Time savings of approx. 10%.
