Definitions
- the invention relates to a device for producing earth bores according to the preamble of patent claim 1.
- a conical displacement head is arranged in front of the tubes to be inserted, the maximum diameter of which is somewhat larger than the diameter of the tube to be drawn in.
- Such a displacement head produces the required borehole on the way of the displacement of the earth. The soil is not cleared, but is pushed radially outwards into the pores of the surrounding substrate.
- a static thrust hydroaulic press or attachment weights
- a dynamic one Ram drilling machine ramming hammer, quick-impact hammer
- a compressed air or oil-powered dynamic ram boring machine whose outer diameter is slightly smaller than the inner diameter of the pipe to be inserted, with the displacement head, which is arranged in front of the pipes to be introduced, has a releasable, non-positive connection. This ensures that the ramming impacts are loss-free and can be implemented in a short distance to earth displacement, thereby creating a borehole into which the pipes can be easily inserted.
- the non-positive connection between the displacement head and the drive unit is released and this is withdrawn within the pipe.
- a dynamic ram boring machine or quick-action hammer this is usually done by switching to reverse.
- Another disadvantage is that the water permeability of the subsoil around the borehole is reduced, particularly in the case of well bores, since the displaced soil closes pores and thus channels through which the water is to flow to the well bore.
- the invention is therefore based on the object of specifying a device of the type mentioned at the outset which, using technically simple means, significantly reduces the displacement or tip resistance during the drilling process.
- a device for the production of earth bores with simultaneous pipe laying comprising an earth boring device with a drive device and a displacement head arranged coaxially to the latter, the outer diameter of which is larger than the outer diameter of the drive device and the tube enveloping it and the non-positive connection to the drive device is releasable, wherein according to the invention at least one liquid jet nozzle is arranged at least approximately symmetrically to the longitudinal axis of the displacement head, which is connectable to a pressure fluid source, pointing approximately in the drilling direction. If there is only one jet nozzle, this means that it is arranged at least approximately at the tip of the displacement head in the longitudinal axis thereof.
- the liquid pressure can vary between approx. 10-300 bar.
- a hydraulic fluid can be used which has thixotropic or lubricant properties.
- additives in the drilling fluid e.g. Polymers that significantly reduce the friction between the pipe to be drawn in and the soil, so that greater lengths or depths are also possible.
- the displacement head has additional liquid jet nozzles which are oriented at least approximately in the opposite direction to the drilling direction, since this loosens up the soil that has already been displaced and improves its water permeability.
- a further improvement of this effect can be achieved in that further liquid jet nozzles are arranged on the displacement head, which are directed outwards perpendicularly to the longitudinal axis of the earth drilling device.
- a directional control of the earth boring device is possible in that the pressure fluid for each fluid jet nozzle is controlled individually with regard to pressure and / or quantity of the pressure fluid.
- the degree of loosening of the soil in a certain angular range around the displacement head of the earth drilling device can be carried out by the selection of the liquid jet nozzles acted upon by hydraulic fluid and / or the choice of pressure in such a way that a large or small change in direction of the earth drilling device can be triggered by this loosening , since in the loosened soil the resistance opposed to the displacement head of the earth drilling rig is reduced and the displacement head of the earth drilling rig inevitably dodges to the side of the lower resistance.
- the same effect can be achieved in that the respective jet angle of the liquid jet nozzles is adjustable.
- the displacement head of the earth drilling device can be designed in a conventional manner.
- the displacement head can be conical in shape and can have grooves distributed symmetrically with respect to the longitudinal axis over the conical surface, in which grooves the liquid jet nozzles are arranged.
- the displacement head can also have a stepped shape and likewise have grooves distributed symmetrically with respect to the longitudinal axis, in which grooves the liquid jet nozzles are in turn arranged. Due to the arrangement of the liquid jet nozzles within the grooves, they are resistant to wear and possible Destruction protected.
- the stepped displacement head has better shattering properties because the stepped surfaces can exert a higher pressure.
- the hydraulic fluid supply to the individual liquid jet nozzles is expediently arranged either in the housing wall of the drive device or between the housing edge and the pipe to be drawn in in parallel to the earth drilling device.
- the ends of the channels for the hydraulic fluid supply, which are remote from the head, are connected to a hydraulic fluid source via flexible lines.
- control valves for controlling the pressure fluid supply to the individual liquid jet nozzles can either be provided in the displacement head itself or on the pressure fluid source.
- the latter embodiment has the advantage that the control lines for controlling the control valves are short and do not have to be pulled along with the earth drilling machine.
- a transmitter can be provided in the displacement head, which emits the desired and suitable position signals.
- Figure 1 is generally designated 10, an earth drilling device, which consists of a quick-action hammer 12 and a displacement head 14, with the help of which a tube or tunnel is to be created in the ground, in which a pipe 16 is drawn in simultaneously with the drilling process.
- the displacement head 14 shown in FIG. 1 has a plurality of liquid jet nozzles 18 which are oriented approximately in the drilling direction and which serve to loosen the soil located in front of the displacement head 14.
- the displacement head 14 shown in FIG. 1 has additional liquid jet nozzles 20 and further liquid jet nozzles 22 which are at least approximately opposite to the drilling direction or perpendicular to the longitudinal axis of the earth drilling machine 10 are directed outwards.
- a plurality of channels 26 are arranged axially parallel to the longitudinal axis of the earth boring machine 10 between the housing of the quick-action hammer 12 and the inner wall of the drawn tube 16. These channels 26 are connected at the far end to the head via flexible lines with the pressure fluid source, not shown.
- control valves 28 which are indicated schematically in FIG. With these control valves 28, the amount and / or the pressure of the individual liquid jet nozzles 18, 20 and 22 supplied hydraulic fluid can be adjusted individually so as to ensure the above-described directional control of the earth boring device 10.
- the compressed air supply for the quick-action hammer 12 takes place via the hose 30.
- Figure 2 shows a stepped displacement head 14, which has better shattering properties for use in hard and stony soil.
- This displacement head 14 has grooves 24 arranged symmetrically to its longitudinal axis, in which here two liquid jet nozzles 18 are arranged one behind the other as an example, the radiation angle of which can be selected to be the same or different, so as to increase the possibility of control.
- the liquid jet nozzles 18 can be connected in a groove 24 to a common or else to separate hydraulic fluid lines.
- FIGS. 3 and 4 each show a liquid jet nozzle 18 which is designed in the form of a slotted screw which can be screwed into the respective nozzle opening and through which a nozzle channel 32 runs.
- the nozzle channel 32 is axially directed, whereas in the embodiment according to FIG. 4 the nozzle channel 32 forms an angle with the screw axis.
- the jet angle of the liquid jet nozzles 18 can be adjusted by screwing in liquid jet nozzles 18 with a differently designed nozzle channel 32. In the case of an obliquely directed nozzle channel 32, the jet direction can also be changed by rotating the liquid jet nozzle 18.
- a ram boring machine has been described as an embodiment. Both the loosening of the soil and the control with the help of liquid jet nozzles arranged on the displacement head of a ram boring machine and through the hydraulic fluid escaping as a result can also be done with a static earth boring machine be used.
- This earth drilling machine is driven not by the ramming impacts of a high-speed hammer, but by the feed pressure introduced via a linkage. Otherwise, however, the statements made regarding the ram boring machine described above also apply in the same way to a static earth boring machine.
- a transmitter 34 shown schematically in FIG. 1, can be arranged in the displacement head 14 of the earth drilling device 10, which enables the earth drilling device 10 to be correctly positioned.
