Definitions
- the invention relates to an apparatus and a method for the controlled manufacture of piles or Pile walls in the floor.
- augers in the ground be screwed in.
- the auger has one with a helical helical tube and they is screwed into the ground like a corkscrew.
- a liquid curable mass e.g. a cement suspension or concrete
- the auger is under continuous rotation pulled out of the borehole while the hardenable mass at the front auger end emerges and fills the borehole. It will Drill hole completely drilled out, i.e. that in the borehole existing soil material is brought to light and must removed or leveled at the construction site.
- the invention has for its object a device and to provide a method of making piles or Pile walls checked using the drilled To produce drilling material.
- the auger tube has a separate inner tube. Auger and inner tube are operated by separate rotary drives, which are separately controllable, driven the inner tube moves axially relative to the auger can be.
- the inner tube carries on its front End a mixing organ.
- the device can be operated in such a way that the inner tube is rotated with the mixing element is going while the auger is moving soil material towards promotes on the mixing organ. This makes it possible to the mixing element when concreting the borehole on the one hand curable liquid mass and on the other hand Feed soil material. These two components will be mixed by the mixing element, so that the soil material is used as an aggregate for the concrete.
- Auger screw While in the known worm drilling device Auger screw after screwing into the ground while maintaining the direction of rotation continuously rotated and is pulled out of the ground, it is with the invention Device possible after the auger promote screwing into the ground in the opposite direction let the soil material towards the To advance the bottom of the borehole. This is possible retraction when the bottom of the borehole is reached the auger is rotating while the Mixing element stops. This will make drilling hard the auger prevents.
- the Auger controls soil material towards Borehole bottom while being withdrawn at the same time becomes. During the withdrawal, the liquid mass pressed into the borehole. The one coming from below Liquid and the soil material coming from above are mixed by the rotating mixing element.
- the mixing element is preferably opposite to that Auger or at a different rotational speed than the auger driven.
- the mixing element is preferably combined with a drill head, who carries chisel elements. This enables to grind stones lying in the drilling path. It is also possible on the rear end of the inner tube Impact device to put over the inner tube To transfer blows to the drill head, making it rocky Obstacles can be smashed.
- the device according to the invention can be used with a single Auger and the associated inner tube be. But it is also possible to use several augers, each with an inner tube, parallel to each other operate together to pile wall elements in one to produce a single operation.
- the method according to the invention provides that the auger screwed into the ground in a first direction of rotation will that the inner tube after reaching the drilling depth with the mixing element relative to the auger is advanced, and then the auger rotated in the opposite direction and withdrawn at the same time becomes liquid while in the inner tube curable mass is introduced, which by the mixing element is mixed with the soil material.
- the drilling device shown has an elongated Mount 10 on a vehicle, e.g. a caterpillar vehicle is attached.
- the carriage 10 consists of a guide bar with one end can be supported on the floor 11 and vertically or rises from the floor 11 at a predetermined angle.
- a carriage 12 can be moved along the carriage 10.
- the carriage 12 is by a chain or Cable operated. It carries a first rotary drive 13 and a second rotary drive 14, which on the Carriage 12 are arranged one behind the other.
- the first rotary drive 13 serves to drive one Auger 15, which has an elongated tube 16, which is formed by a helical spiral 17 is surrounded.
- the helix 17 extends over the entire Length of the tube 16.
- the auger 15 is on an output flange 18 of the rotary drive 13 attached.
- the rotary drive 13 has a controllable hydraulic motor on to the auger 15 with adjustable rotational speed and selectable direction of rotation.
- An inner tube runs through the tube 16 of the auger 15 20, whose channel 21 extends over the entire pipe length extends.
- the inner tube 21 leads through the rotary drive 13 through to the rotary drive 14, of which it rotates is driven.
- the rotary drive 14 also contains a hydraulic motor that regulates the inner tube Drive speed and selectable direction of rotation can.
- a positioning device is located behind the rotary drive 14 22 attached, here from a hydraulic Shift cylinder exists. With the positioning device 22 can the inner tube 21 in the auger 15 axially.
- Fig. 1 is the Positioning device in the state in which the inner tube 20 is withdrawn so that part 20a of the Inner tube by a distance a of e.g. 30 cm from the protrudes rear end of the positioning device 22.
- a Turret 23 connected with a feed device 24 is connected for liquid concrete mass.
- a drill head 27 is attached, the chisel elements 28 wearing.
- the inner tube Outlet openings 29 are on the drill head 27. Further outlet openings are also provided on the drill head 27.
- the rotary drives 13, 14 drive the auger and that The inner tube does not just turn on, it also has an effect also by moving along the carriage 10 the feed.
- the rotary drives 13, 14 have a fixed mutual distance, the displacement of the inner tube 20 by the positioning device 22 takes place.
- Alternative is it is also possible to set the mutual distance between the rotary drives 13, 14 by a positioning device, e.g. to change a hydraulic cylinder.
- Fig. 2 shows that three augers 15 in a common Level are arranged side by side, whereby each auger has an inner tube with a mixing element.
- Each of the three augers are two rotary drives 13.14 assigned and the rotary drives of all Augers are on a common slide 12 arranged. All three augers are in sync with each other controlled.
- the auger 15 is shown in FIG. 1 Condition has been screwed into the floor. It is assumed that the helix 17 is a right-handed helix. In this case, screwing into the ground takes place in Clockwise rotation, the rotary drive 13 the auger 15 only rotates and the carriage 12 tracked becomes. It needs a substantial feed force the slide 12 does not exercise here.
- the inner tube 20 is in the retracted state, as in FIG. 1, where the right-handed snail part 26 of the mixing element 25 continues the helix 17.
- Fig. 3 is reaching the target depth of the borehole 30 shown.
- the inner tube 20 rotating from the front end of the tube 16 of the auger, what in Fig. 3 is shown.
- the positioning device 22 actuated while the rotary drive 14 continues to run, the rotary drive 13 is inactive.
- the mixing element 25 is located at a distance a from the front end of the auger 15, which corresponds to the stroke a of the positioning device 22.
- there is the option of the auger 15 by turning in the opposite direction (left turn) retract a bit while the inner tube 20 stops.
- the drill head 27 is permeable, e.g. star-shaped. While the auger 15 pulled back under rotation, it conveys soil material towards the bottom of the borehole 31. This Soil material mixes at the level of the mixing element 25 with the curable mass.
- the inner tube 20 with the Mixing element 25 is opposite to the auger 15 driven.
- the mixing element to which the snail part 26 and the head 27 belong, causes a thorough Mixing of mass and soil material, so that a Concrete pile 33 of high homogeneity and cylindrical The outer contour is created.
