The invention relates to a ground processing tool and a method for creating a borehole in the ground, wherein ground material is removed by the ground processing tool and blended with a fluid in the created borehole to form a suspension, which is suctioned away via at least one opening in the at least one mixing blade and via the conducting channel in the central shaft.

Ground processing tool and a method for creating a borehole in the ground

An underwater drilling arrangement for marking a bore in a bed of a lake, sea or river with a service platform which can be lowered for placing on the lake, sea or river bed, a drill drive which is mounted so that it is axially displaceable on the service platform, and a drill rod with drill head which can be driven in rotation via the drill drive. A conveying channel is formed in the drill rod, through which a conveying fluid together with excavated drill cuttings can be conveyed upwards, and a discharge opening for the conveying fluid together with the excavated drill cuttings is provided, via which the conveying fluid can be discharged underwater together with the excavated drill cuttings above the drill drive.

Underwater drilling arrangement and method for making a bore

The invention relates to an underwater drilling arrangement and a method for making a bore in a bed of a lake, sea or river, having a service platform which can be lowered for positioning on the lake, sea or river bed, a guide tube which is mounted so that it can be rotated, axially moved as well as fixed on the service platform, a drill rod with drill head which is arranged in the guide tube and can be driven via a drill drive, and a guide tube drive which is arranged on the service platform for incorporation of the guide tube in the lake, sea or river bed. In order to reduce the friction which arises upon incorporation of the guide tube between the outer shell surface of the guide tube and the earth material of the lake, sea or river bed, the guide tube has a sliding support means.

Underwater drilling arrangement and method for making a bore in a bed of a water body

The invention relates to an underwater drilling arrangement for making a bore in the bed of a lake, sea or river with a platform which can be lowered for positioning on the bed of the lake, sea or river, a drill drive which is arranged on the service platform and a drill rod with drill head which can be driven in rotation via the drill drive. It is provided that the service platform comprises a guide tube, on the inner side of which at least one linear guide is arranged, along which at least one part of the drill drive is guided axially displaceably and the guide tube is held so that it can be adjusted and fixed in a mount of the service platform. The invention further relates to a method for creating a bore in the bed of a lake, sea or river.

A method and an apparatus for producing a support element in the ground are described, a hole being sunk through non-stable ground at least down to the load bearing soil. As a result of a wedge-shaped construction of the drill bit the loosened soil is displaced into the adjacent region of the hole and consequently the area round the hole is compacted. The drill has a circular cylindrical core, which is provided with an outlet opening in the vicinity of the drill bit. Preferably tampable material is filled through the core tube, accompanied by the retraction of the drill. The material is simultaneously tamped with the aid of the drill. The invention has the particular advantage that, in cost effective manner, it is possible to use tampable material from the area immediately surrounding the building site and there is no need for expensive, classified filling material. Tubing of the hole is unnecessary through the use of the core tube.
