The invention relates to methods for determining a soil class, in which an earth borehole is introduced into the ground by means of a ground drilling device with a drill head, wherein a parameter of the ground drilling device and/or an operational parameter of the ground drilling device is assessed during the determination of which soil class is involved.

Method and system for determining a soil class and use during determination of a soil class

A method for determining the wear on a linkage of a ground drilling device includes detecting a bending load of the linkage. The bending load is used to carry out a service life calculation.

Method for determining wear on a linkage of a ground drilling device

A ground drilling device having a drilling carriage, which defines a drill string axis, a rod magazine for a plurality of different rod sections and a transfer device for the transfer of a rod section between the rod magazine and the drill string axis, wherein the rod magazine is adapted for a horizontal arrangement of the rod sections in adjacent compartments for access by means of the transfer device from above, wherein a control unit of the transfer device is designed to select a particular rod section in the rod magazine depending on at least one borehole parameter and/or at least one rod section parameter.

Ground drilling device, transfer device of a ground drilling device, control of a transfer device of a ground drilling device and method for control of a ground drilling device

A ground drilling device has a drilling carriage which defines a drill string axis, a drill rod magazine for a plurality of rod sections, and a transfer device for the transfer of a rod section between the drill rod magazine and a position of the rod section in the direction of the drill string axis. The ground drilling device also has a guide on a top of the drill rod magazine that is configured to guide movement of the transfer device.

Ground drilling device and use of a ground drilling device

A ground drilling device having a drilling carriage, which defines a drill string axis, a first drill rod magazine for a plurality of rod sections and a transfer device for the transfer of a rod section between the first drill rod magazine and a position of the rod section along the drill string axis, wherein at least a first connection element is arranged at the first rod magazine and/or at the drilling carriage for the connecting of the first rod magazine to a second rod magazine such that the second rod magazine is arranged next to the first rod magazine.

Ground drilling device, system comprising a ground drilling device, method for earth drilling and use of a ground drilling device

The invention relates to a device for locating a drill head of a ground drilling device, comprising a wireless probe, the probe being arranged on or in a flying object.

Locating a drill head of a ground drilling device

It is described how to provide a drilling fluid for earth drilling, wherein the drilling fluid comprises a liquid and at least one mineral. A recycling device preconditions supplied drilling fluid. At least one drilling fluid analyzer is provided for determining the state of drilling fluid that comes out of the borehole. There is also a mixing device for mixing drilling fluid reconditioned by the recycling device with liquid and/or mineral, wherein the mixing device is coupled to the drilling fluid analyzer in order to perform mixing according to the state of the drilling fluid.

System and method for providing drilling fluid for earth drilling

A top surface drilling device has a core bit and a drill head disposed in the core bit. The drill head has a smaller diameter than that of the core bit, and the core bit and the drill head can be driven at different angular speeds.

Top surface drilling device and methods for drilling a core in a top surface

A drive of a slide which can move back and forth of an earth drilling device to move a drill string, wherein a rod, which can move relative to a cylinder, and tension transmitting means are provided in a frame and act on the slide, wherein the rod is connected to the frame, and deflection rollers are provided for the tension transmitting means on the frame and on the cylinder.

Drive of an earth drilling device, earth drilling device, and a method for driving an earth drilling device

The invention relates to a drive of a slide of an earth drilling device having a rotary drive and a pinion that is driven by the rotary drive and can be engaged with a rack, wherein the rotary drive is engaged with another pinion which can be engaged with the rack.

A drill string section includes at least one plug-and-rotate seat (bayonet seat) for interacting with a (bayonet) catch, wherein the seat allows an additional plug-in step for fixing the catch in a connection secure against rotation in both directions of rotation about the longitudinal axis of the drill string section.

Drill string, connection system, earth drilling device and method to connect a drill string section

A method for producing a horizontally drilled bore hole in the ground includes the steps of producing a pit having a circular cross-section; lowering a horizontal drilling device into the pit, the horizontal drilling device having a circular cross-section in at least part of the section in which it is positioned once it is lowered into the pit; and producing a horizontally drilled bore hole using the horizontal drilling device.

Method for producing a horizontal bore in the ground and horizontal drilling device

A horizontal drilling device according to the invention includes a linear drive, a rotary drive that can be displaced by means of the linear drive, a drill rod assembly and a rod assembly pipe receiver, the drill rod assembly being hollow and the rod assembly receiver being designed as a receiving mandrel, which allows the drill rod assembly to be placed on the receiving mandrel.

Horizontal drilling device

A dual pipe rod assembly section includes an inner rod section and an outer rod section, with a probe which is arranged in the dual pipe rod assembly section, a horizontal drilling device and a probe housing. The probe is arranged in the inner rod section and rotationally coupled to the outer rod section.

Dual pipe rod assembly section, horizontal drilling device and probe housing

A plug connection for connecting two pipe sections of a drill pipe has a connecting plug on one end of a first of the pipe sections and a connecting bushing on one end of the second pipe section. The connecting plug and the connecting bushing have helical meshing guide projections and/or guide grooves. A pipe section for a drill pipe has on one of its ends a corresponding connecting plug and on the other end a corresponding connecting bushing.
