Patent number: 8820015Abstract: 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.Type: GrantFiled: April 3, 2013Date of Patent: September 2, 2014Assignee: Bauer Spezialtiefbau GmbHInventors: Marcus Daubner, Ralf Meyer, Andreas Ackermann, Christoph Schroeppel

Patent number: 6223837Abstract: The invention relates to a drilling implement for drilling holes in the soil. In known drilling implements, drilling tools, such as drill tubes or drill rods, are stored and handled via magazines and magazine forms which require a considerable outlay on sensors and control engineering in order to position the drilling tools. In the drilling implement according to the invention, there is provision for stops to be provided as mechanical travel-limiting mechanisms when the drill tubes are being positioned in respective functional positions. This obviates the need for sensor and control devices which are expensive and susceptible to faults.Type: GrantFiled: June 23, 1999Date of Patent: May 1, 2001Assignee: Bauer Spezialtiefbau GmbHInventor: Martin Lanzl

Patent number: 6199442Abstract: A slewing ring brake for use in heavy machinery including earthworking machinery. The slewing ring brake includes a slewing ring with a tooth system and a support member which is mounted in a manner to allow rotary movement of the support member relative to the slewing ring. The slewing ring brake also includes a brake block displaceably mounted on the support member, the brake block being displaceable between a braking position and a freewheeling position. In the braking position, the brake block engages with the tooth system thereby preventing rotary movement of the support member relative to the slewing ring.Type: GrantFiled: March 26, 1999Date of Patent: March 13, 2001Assignee: Bauer Spezialtiefbau GmbHInventors: Sebastian Bauer, Werner Harthauser

Patent number: 5931235Abstract: A cutter head for retrieving earth samples, in particular for taking underwater samples, has, because of frustum-shaped cutting wheels, an approximately round bore cross section. In an associated boring jig, a tube with a cross section corresponding approximately to the bore cross section is placed above the cutter head. With a regrasping system, the tube can be moved vertically relative to a work table lying on the bore surface. The boring jig may be lowered from a ship to the sea bottom to conduct the boring process.Type: GrantFiled: July 16, 1997Date of Patent: August 3, 1999Assignee: Bauer Spezialtiefbau GmbHInventor: Leonhard Weixler

Patent number: 5924222Abstract: The invention relates to a trench wall cutter with a cutting frame and a gear shield attached thereto. There is at least one cutting wheel positioned to turn on the opposite shield sides, and on it roller-shaped excavation tools distributed over the periphery are pivotally mounted. When the cutting wheel is rotating the tools form a cutting wheel cutting surface which runs essentially axially parallel to the axis of rotation of the cutting wheel. To accommodate horizontal forces, at least one additional roller is pivotally mounted on each cutting wheel, the axis of the additional roller being directed substantially radially with respect to the axis of rotation of the cutting wheel. One jacket surface of the roller on the radial face side of the cutting wheel away from the gear shield projects in the direction of the axis of rotation of the-cutting wheel.Type: GrantFiled: November 13, 1997Date of Patent: July 20, 1999Assignee: Bauer Spezialtiefbau GmbHInventor: Erwin Stoetzer

Patent number: 5267902Abstract: A rotation elastic damped cutting device of a slitting cutter with at least one cutting wheel and a driven shaft for driving the cutting wheel, allows absorption of an abrupt, shockproducing blocking force. A rotation elastic dampener is provided in a radial space between the driven shaft and the cutting wheel as a cylindrical bushing. The cutting wheel and the driven shaft are connected by at least one wall, respectively, and the elastomer is vulcanized on one of these walls. A circumferentially fixed metal sleeve is inserted between the elastomer and the other wall for causing a radial pressure on the elastomer, effecting a good friction grip between the elastomer and the metal sleeve.Type: GrantFiled: April 12, 1990Date of Patent: December 7, 1993Assignee: Bauer Spezialtiefbau GmbHInventors: Maximilian Arzberger, Johann Haberer
