A rock-piercing flexible rock drilling robot and a rock breaking method therefor are disclosed. The robot includes a control system, a head, and at least one tail. The head includes a head housing, a propulsion turntable, a drilling mechanism, a hydraulic propulsion system, a first driving mechanism, and a second driving mechanism. The propulsion turntable includes a drill bit located at a center thereof and a cutting turntable arranged around the drill bit. The first driving mechanism is connected to the drill bit, and the second driving mechanism is connected to the cutting turntable. The tail includes a tail housing, an advancing and retreating power system, and a fixed support system. The head and the tail are connected through a flexible component, and the tails are connected through flexible components.

The present invention relates to a device for laying pipes (1) in the ground, the device comprising a ploughshare (2) with a ploughshare shoe (3), wherein the ploughshare shoe (3) has at least one displacement element (5) protruding in a laying direction (4), a drill (6), which drill (6) is connected to the ploughshare (2) and comprises at least one drill head (7) arranged in a drill head housing section (7a) of a drill housing and a conveyor device (8) arranged in a conveyor housing section (8a) of the drill housing for removing drilled material, and a connection device (9) for connecting a pipe (1) to be laid to the drill (6), wherein the ploughshare (2) is arranged behind the drill (6) when viewed in the laying direction (4).

A kinetic penetrator includes a tubular body having a first end and a second end, a nose coupled to the first end of the tubular body, the nose configured to penetrate a ground surface and subsurface materials of a subterranean ground volume, a retrieval system including a tether, a collector coupled to at least one of the nose and the tubular body, and a sample compartment configured to interface with the collector. The sample compartment is releasably coupled to at least one of the tubular body, the nose, and the collector, and the tether is coupled to the sample compartment and is configured to facilitate removal thereof from the subterranean ground volume.

A drilling bucket for drilling a bore hole in the ground including a hollow cylindrical body and at least one cutting tool arranged at a lower side of the hollow cylindrical body for cutting soil material. The hollow cylindrical body has a lower opening for receiving soil material cut by the at least one cutting tool. For guiding the hollow cylindrical body in the bore hole an upper guiding device is provided which is arranged above the hollow cylindrical body and fixed to the hollow cylindrical body. The upper guiding device is configured to abut on a side wall of the bore hole.

A retrievable kinetic penetrator includes a tubular body having a first end and a second end, a nose coupled to the first end of the tubular body, and a retrieval system. The nose is configured to penetrate a ground surface and subsurface materials of a subterranean ground volume. The retrieval system includes a tether coupled to the tubular body and is configured to facilitate recovery of the tubular body from the subterranean ground volume.
