  • a support pipe is arranged in the guide device.
  • a drilling rig which is inserted into the support pipe, a bore is created into which the support pipe is lowered.
  • a foundation element can be inserted into the support pipe.
  • the support pipe is then withdrawn, filling any space between the bore wall and the inserted foundation element.
  • a device and method for constructing an underwater foundation are disclosed. This also involves inserting a support pipe into the ground, into which a down-the-hole drilling rig is positioned.
  • the down-the-hole drilling rig removes soil material, allowing the surrounding support pipe to be pushed axially.
  • EP 3 333 324 A1 Another known device and method for constructing a foundation for a structure in water is known from EP 3 333 324 A1 out.
  • the EP 2 562 348 A1 or the EP 2 527 539 A1 disclose the preamble of claim 1.
  • the invention is based on the object of specifying a drilling device and a method with which a cased borehole under water can be created particularly efficiently.
  • the object is achieved, on the one hand, by an underwater drilling device having the features of claim 1 and, on the other hand, by a method having the features of claim 12.
  • Preferred embodiments of the invention are specified in the dependent claims.
  • a first aspect of the invention is to provide at least one pipe drive for rotatingly driving the support pipe on the lowerable platform in an underwater drilling device, wherein the pipe drive is designed to rotately insert the support pipe into the waterbed.
  • the underwater drilling device with the pipe drive is designed such that a down-the-hole drilling rig arranged in the support pipe is clamped to the support pipe when the support pipe is rotated, so that the support pipe rotates with the rotating support pipe.
  • a down-the-hole drilling rig arranged in the support pipe is clamped to the support pipe when the support pipe is rotated, so that the support pipe rotates with the rotating support pipe.
  • either the support pipe or the drill head of the drilling rig can advance. While the drill head is rotating, the drilling rig can be clamped to the stationary support pipe. After a drilling step with the drill head of the drilling rig, the support pipe can be inserted into the ground by a further rotational advance, with the down-the-hole drilling rig remaining connected to the support pipe in a rotationally fixed manner.
  • the drill head can be driven to rotate relative to the device base at the same time, in the same or the opposite direction of rotation as the support pipe.
  • the tubular drive on the lowerable platform can be configured in any suitable manner for rotating the support tube.
  • a preferred embodiment of the invention consists in the fact that, to form the tubular drive on the platform, a collet device for clamping the support tube is arranged on its outer side in a rotatable or pivotable manner and axially movable, wherein a torque of the tubular drive can be transmitted to the support tube.
  • the pipe drive can be designed similarly to a casing rigging device, with a collet chuck allowing a releasable grip on the outside of the support pipe.

Through coordinated, sequential rotation by at least two such arrangements, a continuous or quasi-continuous rotation of the support tube can be achieved.
  • the tube drive is designed to transmit an oscillating rotary movement to the support tube.
  • This oscillating or step-by-step rotary movement can be achieved, in particular, by an arrangement with a single collet device.
  • the down-the-hole drilling rig can be suspended in the support tube via a suspension cable, so that the feed force can be applied solely by the weight of the down-the-hole drilling rig.
  • the down-the-hole drilling rig has an axial feed device with which the drill head can be axially displaced relative to the device base body.
  • the device base body can have a frame structure which can be rotationally fixed in the inner wall of the support tube, preferably via radially extendable hydraulic clamping cylinders.
  • the feed device can have one or more hydraulic actuating cylinders aligned in the axial direction. This allows a rotationally driven drill head to be axially displaced relative to the device base body.
  • the drill drive which can preferably have one or more hydraulic rotary motors, can be axially fixed to the base body, with a drill drive shaft being axially telescopic by means of appropriate spline teeth or another suitable configuration.

  • the feed cylinder can be a single-acting or double-acting actuating cylinder.
  • the platform can be designed as a template for a predetermined arrangement of support tubes in a body of water.
  • a separate down-the-hole drilling rig can be arranged in each support tube.
  • a single down-the-hole drilling rig can be provided. which is initially inserted into a first support tube to create a first borehole. After creating the first borehole, the down-the-hole drilling rig can be released and withdrawn from the first support tube and inserted into a second support tube to create a second cased borehole. This can be repeated as many times as necessary.
  • Pipe drives are preferably arranged on the platform, corresponding to the number of support tubes planned.
  • the down-the-hole drilling rig is connected to a supply unit, in particular a supply vessel, on the water surface via one or more lines, in particular a so-called umbilical.
  • Energy in particular electrical energy and/or hydraulic energy, is transmitted via the one or more lines.
  • the at least one line can be connected to the down-the-hole drilling rig via a corresponding rotary coupling in an upper area of the down-the-hole drilling rig.
  • a so-called rotary union can be provided, in particular, for the passage of hydraulic fluid.
  • a simplified embodiment of the invention for preventing twisting of the at least one cable consists in arranging at least one upper clamping device on the tool base and at least one lower clamping device on the drill head.

  • the at least one lower clamping device on the drill head is radially extended and the drill head is clamped to the support tube, and the at least one upper clamping device on the tool body is radially retracted and released from the support tube.
  • the rotary drive can be decoupled from the drill head, or a freewheel can be selected.
  • the device base body is clamped and fixed to the support tube so that the down-the-hole drilling device is screwed in with the support tube.
  • a further preferred embodiment of the invention consists in that the platform on the waterbed has a supply device which is connected to a surface supply unit via at least one main supply line, and in that the at least one pipe drive and the at least one down-the-hole drilling rig are connected to the supply device of the platform for energy supply, in particular via supply lines.
  • the supply device on the platform can preferably store energy to a certain extent, for example electrical energy through provided accumulators or hydraulic energy through corresponding pressure accumulators.
  • the platform can thus be operated autonomously for a certain period of time, which may be necessary, for example, in harsh weather conditions and the associated disconnection of the main supply line.
