    摘要： A foundation (1) for a structure such as an off-shore wind turbine. The foundation (1) comprises a body (4) having a lateral surface (8,9) and a distal end (5) for insertion into a soil (2). At least a region of the lateral surface (8,9) forms a first electrode. A second electrode (7) is provided on the lateral surface (8,9) of the body (4) and is electrically insulated from the first electrode. The body (4) further comprises a spacing formation (6) for forming a gap (11) between the second electrode (7) and the soil (2) when the body (4) is inserted into the soil (2). In use, an electric potential may be established between the electrodes to induce electro-osmosis in the soil for allowing the foundation to be installed more easily. The polarity of the electric potential may also be reversed for stabilising the foundation.

    摘要： Method for forming at least one foundation pile or deep wall in the ground, comprising the step of sinking one or more hollow foundation elements (1) into the ground with a substantially vertical orientation. The sinking of the foundation element (1) into the ground takes place during driving of a removable drilling head (3), which drilling head (3), during the sinking of the foundation element (1), extends at least partially below a bottom part of the foundation element (1), by means of excavating members, which can rotate with respect to the foundation element (1) and have radial dimensions which in particular are greater than or equal to external dimensions of the foundation element (1), in which the excavation members, at the same time as the foundation element (1) is being sunk, drills out earth beneath the said bottom part of the foundation element (1), and in which at least the drilling head (3), after the foundation element (1) has been sunk, is removed again from the ground.

    摘要： The actuator 20 may be used for pile driving. An arrangement 30 can clamp the actuator to a pile or other item to be driven. A vibrator is provided at 32. A carriage 36 is for mounting the actuator 20 on a support structure such as a tracked rig (not shown). A suspension arrangement 38 supports the clamp 30 on the carriage 36 and isolates the carriage 36 from vibration created by the vibrator 32. Crowd can be conveyed from the carriage 36 to the attachment arrangement 30, through the suspension arrangement 38. Accordingly, vibration and crowd forces can be applied to the item clamped at 30, but the carriage 36 (and thus the supporting rig) is isolated from the vibration by the suspension arrangement 38.
