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 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

An apparatus for mixing a powdery medium with a fluid includes a mixing vessel which can be filled with the fluid and which has a feed for the fluid, an inlet for the powdery medium and an outlet for the fluid mixed with the powdery medium, and at least one mixing screw arranged inside the mixing vessel and driven by a rotary drive.

Apparatus for mixing a powdery medium with a fluid

The application relates to a metering apparatus for introducing a powdery medium into a fluid, comprising a guide device for guiding the fluid and a metering device, said metering device being arranged above the guide device such that the powdery medium released by the metering unit is scattered onto the surface of the fluid.

Metering apparatus and method for introducing a powdery medium into a fluid

A metering apparatus for introducing a powdery medium into a fluid includes a mixing vessel that can be filled with a fluid and a metering unit for the powdery medium. The metering unit has an inlet for the powdery medium, an inlet for a compressed gas and an outlet extending towards the mixing vessel, through which the powdery medium and the compressed gas can be discharged into the mixing vessel.

An apparatus for mixing a powdery medium with a fluid includes a mixing vessel which can be filled with the fluid and which has a feed for the fluid, an inlet for the powdery medium and an outlet for the fluid mixed with the powdery medium, and at least one mixing screen which divides the mixing vessel into a first section which includes the feed and a second section which includes the inlet.
