20160083927 | CLEANING DEVICE FOR CLEANING A BOTTOM OF A BOREHOLE AND METHOD FOR CREATING A FOUNDATION ELEMENT - 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. | 03-24-2016 |
20150008040 | DRILLING DEVICE AND DRILLING METHOD - 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. | 01-08-2015 |
20140238749 | DRILLING TOOL AND METHOD FOR EARTH DRILLING - The invention relates to a drilling tool for earth drilling with a drill rod element which can be connected to a rotary drive and can be driven in a rotating manner about a drilling axis, a frame-like housing and at least one removal tooth which is supported in a radially adjustable manner in the housing between a retracted position in the housing and an operating position, in which the at least one removal tooth projects radially from the housing. | 08-28-2014 |
20140041447 | METHOD AND DEVICE FOR PRODUCING AND MEASURING A BOREHOLE - The invention relates to a method and a device for producing and measuring a borehole in the ground. As far as the method is concerned, provision is made in that the borehole is produced through drilling, that between a carrier unit above a ground surface and a measuring body a measuring rope is tensioned, that the measuring body is inserted so as to fit into the borehole in the ground and lowered, that by means of angle and distance measurements the positions of at least two vertically spaced rope points of the tensioned measuring rope are ascertained and in that on the basis of the ascertained positions of the rope points the position of the measuring body in the borehole is determined as a measure for the location of the borehole. | 02-13-2014 |
20140034385 | DRILLING BUCKET AND METHOD FOR DRILLING A BORE HOLE - 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. | 02-06-2014 |
20130255180 | SHUTTERING ELEMENT FOR A TRENCH WALL AND METHOD FOR PRODUCING THE TRENCH WALL - The invention relates to a shuttering element for a trench wall and to a method for producing the trench wall. To form the trench wall in the ground a first trench is produced initially, which is filled with a hardenable mass for forming a first trench wall segment. After the production of the first trench and before a hardening of an infilled mass into the first trench wall segment a shuttering element is arranged on at least one front face of the first trench. The shuttering element has a board-shaped base body comprising a first shuttering surface and a second shuttering surface, between which a receiving bead is arranged which is recessed with respect to the two shuttering surfaces. In the receiving bead a sealing tape is arranged which extends along the base body. The receiving bead is covered by a cover element, wherein a receiving space is enclosed in which the sealing tape is arranged. | 10-03-2013 |
20130227862 | TRENCH WALL CUTTER AND METHOD FOR PRODUCING A TRENCH IN THE GROUND - The invention relates to a trench wall cutter for producing a trench in the ground having a cutter frame and at least one cutting wheel which is supported in a rotatable manner about an axis of rotation on the cutter frame and has at its outer circumference a plurality of ground working tools for removing ground material. The ground working tools are arranged along an annular path around the axis of rotation. Provision is made for the annular path to run asymmetrically to the axis of rotation of the cutting wheel, wherein the annular path has at least one first circumferential section with a larger distance from the axis of rotation and at least one second circumferential section with a smaller distance from the axis of rotation. The invention furthermore relates to a method for producing a trench in the ground. | 09-05-2013 |
20130223939 | METHOD AND ARRANGEMENT FOR PRODUCING A TRENCH WALL ELEMENT - The invention relates to a method for producing a trench wall element in the ground, in which a trench is produced in the ground through removal of ground material by means of a removal device and a hardening medium is introduced into the trench in order to form the trench wall element. Provision is made in that between the removal device and a carrier device at least two ropes are tensioned, for which the respective positions of at least two vertically spaced rope points of a rope are ascertained through angle and distance measurements by means of a measuring device, and in that the ascertained positions of the rope points are used to determine a location of the removal device in the ground. The invention furthermore relates to an arrangement for producing a trench wall element. | 08-29-2013 |
20120315097 | METHOD FOR PRODUCING AN UNDERWATER FOUNDATION ELEMENT, ADJUSTMENT HEAD FOR AN UNDERWATER FOUNDATION ELEMENT AND UNDERWATER WORKING ARRANGEMENT - The invention relates to 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, with the drilling tool 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 means of at least one positioning means on the working platform prior to anchoring. In accordance with the invention the measuring unit is arranged on an adjustment head. | 12-13-2012 |
