The invention relates to a trench cutter for producing a cut trench in the soil with a cutter frame, at least one pair of cutting wheels which are supported and driven in a rotatable manner on a lower end of the cutter frame, wherein each cutting wheel has a plurality of cutting teeth along its external circumference, and a discharge means with at least one discharge pump for discharging a cutting fluid from the cut trench in the region of the cutting wheels. According to the invention a switchover means is provided which is designed for switching the discharge means over to a flushing operation, in which a fluid flow generated by at least one discharge pump of the discharge means is generated onto at least one cutting wheel for flushing out the cutting wheel.

The invention relates to a drilling bucket and a method for producing a bore with a drilling bucket, wherein the drilling bucket is driven in a rotating manner and introduced into the ground, wherein ground material is removed and received in an internal space of a tubular base body of the drilling bucket, and for emptying the drilling bucket is withdrawn from the bore and a bottom on the tubular base body is folded open. According to the invention the drilling bucket is rotated in a reversing manner during emptying, wherein ground material received in the drilling bucket is pressed against at least one impact wall and, in doing so, the ground material is specifically compacted and deformed for easier loosening from the internal space.

The invention relates to a method for ground-working at a bottom of a body of water and a cleaning device for cleaning an underwater ground-working apparatus. The cleaning device has an enclosing body which extends substantially from a bottom of a body of water to above the water surface and enclosing an inner space, along which the ground-working apparatus can be moved, and a separating device, through which in the enclosing body an upper portion of the inner space can be separated off to form a cleaning area, in which the ground-working apparatus can be received and soil and contamination cleaned from it.

Cleaning device for cleaning an underwater ground-working apparatus and method

The invention relates to a cleaning device for cleaning a bottom of a borehole in the ground and also to a method for creating a bored pile in a borehole. The cleaning device has a pumping means, through which sedimented ground material in the region of the bottom of the borehole can be sucked away via a suction opening and can be discharged from the borehole via a suction line. At least one flushing nozzle is provided, through which a flushing jet can be produced, which exits the cleaning device and flushes sedimented ground material from the bottom of the borehole. A bored pile can then be produced in a thus cleaned borehole.

The invention relates to a maritime supply line with at least two line elements which respectively comprise a jacket pipe, at least two inner lines which are arranged in the jacket pipe and a connecting element arranged at least at one end of the line element for the formation of a watertight connection to a line element to be connected. It is provided according to the invention that the connecting element comprises a connecting flange with a radially projecting collar, on which a radially projecting collar of a connecting flange of the line element to be connected can be placed. For the formation of the watertight connection the two radially projecting collars are incorporated by at least one tensioning clamp and are axially tensioned against each other.

Maritime supply line

A drilling device and method with a drill rod which can be driven in a rotating manner and has an internal line, a support rope, a rotary joint between the drill rod and the support rope and has a holding member which is in connection with the support rope and a rotary member which is in connection with the rotatable drill rod, a line and a rotary feed-through which is designed for the passage of fluid and/or data between the line and the internal line of the drill rod, wherein the rotary feed-through has a rotor connected to the drill rod and a non-rotating stator, to which the line is attached. Provision is made for the support rope to be designed in a torsion-proof manner and for a rigid connecting element to be arranged as a torque support between the stator of the rotary feed-through and the torsion-proof support rope.

Drilling device and drilling method

A device for introducing a filling material into a hole in the ground, with a channel-like filling section which can be introduced into the hole and has an upper feed opening for feeding in the filling material and a lower discharge opening for discharging the filling material in a lower area of the hole. The filling section includes an upper feed section and a flexible hose section arranged below. During the filling of the hole with the filling material the flexible hose section can be moved upwards along the feed section. During upward movement of the flexible hose section a severing device severs an upper area of the hose section in a longitudinal direction. Furthermore, the invention relates to a method for introducing a filling material into a hole.

Device and method for introducing a filling material

The invention relates to an underwater work assembly and to a method for anchoring the underwater work assembly in a bed of a lake, sea or river. The work assembly comprises a service platform which can be lowered and a plurality of supporting feet which are mounted so that they can be adjusted on the service platform for positioning on the lake, sea or river bed and can be moved in and out relative to the service platform by means of an actuating cylinder. In order to improve anchoring it is provided that at least one supporting foot is mounted rotationally relative to the service platform and that a rotary drive facing the supporting foot is provided, with which the supporting foot is driven in rotation for screwing into the lake, sea or river bed.

Underwater work assembly and method for anchoring thereof

A method for producing an underwater foundation element in a bed of a body of water, in which a working platform for guiding a drilling tool is lowered to the bed of a body of water, so that a drill-hole is introduced into the bed of a body of water and a pile-shaped underwater foundation element is arranged in the drill-hole and anchored therein. A precise alignment is achieved in that on the pile-shaped underwater foundation element a measuring unit is fixed, through which positional data of the pile-shaped underwater foundation element are determined and in that depending on the determined positional data the position of the underwater foundation element is set by at least one positioning means on the working platform prior to anchoring. The measuring unit is arranged on an adjustment head.
