Abstract
A rod section of a ground drilling rod configured at its end to form at least one plug connection and having at one end (a) a connecting plug with an outer contour; or (b) a connecting socket with an inner contour, the outer contour or the inner contour being essentially sinusoidal in cross section.
Claims12
A rod section of a ground drilling rod,
- the rod section comprising an end that is configured to form at least one plug connection and
- wherein the end comprises
- (a) a connecting plug having an outer contour;
- or
- (b) a connecting socket having an inner contour;
- wherein the outer contour or the inner contour is essentially sinusoidal in cross section,
- wherein the outer contour and the inner contour have straight lines.

A drive element for impact driving a ground drilling rod into the soil, wherein the drive element engages with a rod section and
- wherein the rod section comprises an end that is configured
- (a) as a connecting plug or
- (b) as a connecting socket;
- wherein the connecting plug has an outer contour in cross section or
- the connecting socket has an inner contour in cross section,
- wherein said outer contour cross section or said inner contour cross section are essentially sinusoidal,
- wherein the outer contour cross section and the inner contour cross section have straight lines.
4 more elements
A rod section system of a ground drilling device, the rod section system comprising
- two or more rod sections,
- wherein at least one of the rod sections has a connecting plug comprising an outer contour in cross section, and
- at least another one of the rod sections has a connecting socket comprising an inner contour in cross section, and
- wherein each one of the outer contour and the inner contour are essentially sinusoidal in cross section and each having straight lines,
- wherein an angle (β) of the straight line of the outer contour to a centerline (X-X) of the cross section is greater than an angle (α) of the straight line of the inner contour to the centerline (X-X) of the cross section.
