Patent number: 4768897Abstract: A multilayer plate for use in covering waste depositories comprises at least one drainage layer and a filter stabilization layer, the drainage layer serving to facilitate or enable the removal of water seeping downwardly from the surface of the depository covering or gases rising from the depository body. The filter stabilization layer comprises a fabric web, while the drainage layer includes a plastic grid. The plate is prefabricated and is of sufficient flexibility to be wound upon a roll for transport to a depository site. In one form, the prefabricated plate also includes a synthetic resin barrier layer which, upon installation of the plate, blocks the passage of water from above and the passage of gases from below.Type: GrantFiled: December 6, 1985Date of Patent: September 6, 1988Assignee: Ed.

Patent number: 4697953Abstract: A method and apparatus for the subsequent underground sealing of an area, preferably of dumps. With the method, it is possible to seal dumps underground. Working pipes are introduced from a region outside a dump body. The region of soil between the working pipes is loosened, and sealing material is then introduced into this region, which solidifies to become a sheet-like sealing compound. With this method, in particular existing dump bodies can be sealed subsequently underground, without having to drill through the dump body. The apparatus for carrying out the method has a loosening device, and a feed device for the sealing material. The two devices are able to move in the region between two adjacent working pipes.Type: GrantFiled: February 28, 1985Date of Patent: October 6, 1987Assignee: Ed. Zublin AktiengesellschaftInventors: Manfred Nussbaumer, Eberhard Glaser, Eberhard Beitinger, Hartmann Eckardt

Patent number: 4690590Abstract: To reduce the shearing resistance at the surfaces of the diaphragm, and to decrease the buoyancy force, both of which greatly hamper the positioning of diaphragms or thin sheets in slotted wall suspensions, air bubbles are introduced at the bottom end of the diaphragm during the positioning process. These air bubbles ascend along the vertical surfaces of the diaphragm.Type: GrantFiled: August 22, 1985Date of Patent: September 1, 1987Assignee: Ed. Zublin AktiengesellschaftInventors: Manfred Nussbaumer, Eberhard Glaser, Eberhard Beitinger

Patent number: 4679965Abstract: For installing panels consisting of diaphragm portions and reinforcements into recesses in the ground a deflection body is provided which is movable along the opening of the ground recess, the upper surface of the deflection body being curved so that the panels can be inserted into a suspension in the ground recess via the deflection body without discontinuities and without bending the panels over a deflection radius smaller than the smallest possible bending radius of the panels. Welding machines are disposed on the deflection body for joining the panel sections transversely and longitudinally to form a web having a length which corresponds to the depth of the suspension filled recess in the ground.Type: GrantFiled: December 6, 1985Date of Patent: July 14, 1987Assignee: Ed. Zublin AktiengesellschaftInventors: Eberhard Glaser, Eberhard Beitinger

Patent number: 4678771Abstract: An adsorption layer for retaining liquid or gaseous organic hydrocarbons prior to such matter reaching a sealing sheet of synthetic material. The adsorption layer includes activated carbon that is incorporated loosely or is bonded to the sealing sheet. Retention of the organic hydrocarbons in the adsorption layer prevents possible diffusion of this matter through the plastic sealing sheet.Type: GrantFiled: February 13, 1986Date of Patent: July 7, 1987Assignee: Ed. Zublin AktiengesellschaftInventors: Eberhard Beitinger, Eberhard Glaser

Patent number: 4673316Abstract: A method for installing thin-walled sealing elements in the fabrication of slotted walls in the soil. The thin-walled sealing elements are plastic foils with vertical connecting elements at the vertical edges. A connecting slot is flushed out between a newly made slotted-wall section and the interior of the adjacent slotted connecting tube of the previously installed sealing element. The slot and the interior of the connecting tube are filled with a support suspension. Then a new sealing element is threaded through the filled connecting slot into the previously installed connecting tube.Type: GrantFiled: December 6, 1985Date of Patent: June 16, 1987Assignee: Ed. Zublin AktiengesellschaftInventors: Manfred Nussbaumer, Eberhard Glaser, Eberhard Beitinger

Patent number: 4671705Abstract: A pair of webs each extending over a large area and disposed in a vertical orientation in a suspension are interconnected by a pair of telescoping tubes attached to juxtaposed edges of the respective barrier webs. Material of the suspension is removed from the space within the inner tube to provide a hydraulic trap for liquid entering the connection or coupling between the two tubes. A device is provided for inspecting the level of the liquid collected in the hydraulic trap or for removing the collected liquid. The barrier webs are advantageously made of synthetic resin material such as high-density polyethylene.Type: GrantFiled: October 4, 1985Date of Patent: June 9, 1987Assignee: Ed. Zublin AktiengesellschaftInventors: Manfred Nussbaumer, Eberhard Glaser, Eberhard Beitinger

Patent number: 4647256Abstract: A method of producing underground pipes, with pipe sections being pressed ahead into the ground. For each pipe section, at least two partial pipe shells are used which are separated from one another in the longitudinal direction, and are joined about supply lines which are guided through the pipe. The joining process is effected before the pipe section is pressed into the ground. With this method, the supply lines do not have to be interrupted when a new pipe section is introduced. The apparatus for carrying out the method is provided with at least one joining station for joining the partial pipe shells in a precisely fitting manner, and a combining station for interconnecting the partial pipe shells.Type: GrantFiled: February 28, 1985Date of Patent: March 3, 1987Assignee: Ed. Zublin AktiengesellschaftInventors: Volker Hahn, Eberhard Beitinger

Patent number: 4513504Abstract: A method and apparatus for determining the position of a pressed-ahead hollow-section line, especially with any desired three dimensional curvature, and having measuring points permanently and securely arranged in the hollow-section line. The three dimensional position of the measuring points, e.g. signal emitters, is detected by automatic sensing devices e.g. cameras, having remote control or long-distance transmission, and being arranged in the hollow-section line.Type: GrantFiled: May 20, 1982Date of Patent: April 30, 1985Assignee: Ed. Zublin AktiengesellschaftInventors: Manfred Nussbaumer, Eberhard Beitinger, Wolfgang Mohlenbrink

Patent number: 4501446Abstract: A method for removing fine-grained sediments from flowing or standing bodies of water. The sediment is dredged from the bottom of the body of water. The dredged sediment is dewatered and classified in a sieve plant. At least a fine-grained admixture material such as fly ash or refined clay is admixed to the dewatered sediment material. The admixture is granulated and the resulting granulate is dried and fired under swelling. The swelled, fired granulate is cooled and further processed. The light weight granulate is admixed to concrete or used in the production of building materials such as sinter blocks and bricks. The noxious materials and heavy metals contained in the sediment are substantially sealed into the granules produced by sintering. The resulting waste waters can be cleared such that they are suitable for feeding back into the bodies of water. The residues of the waste water treatment can also be employed as admixture component in the granulate production.Type: GrantFiled: September 24, 1982Date of Patent: February 26, 1985Assignee: Ed.
