Patent number: 5076730Abstract: A method of and an apparatus for relieving ground pressure surrounding pvc vent pipes which have been displaced from their T-fitting traps in sewer systems. The round tubular nature of a semi-rigid pipe is changed to an elliptical or oval shape with initial insertion and rotation of a special tool.

Patent number: 5011331Abstract: A method for constructing underground garage parking units comprises a step of excavating two parallel trenches into which are subsequently sunk preformed reinforced concrete frames each composed of two vertical pillars with an "H"-shaped cross-section and upper and lower horizontal connecting beams disposed between them. The vertical grooves forming the "H" sections being opposed and constituting a guide for the insertion of a plurality of sheet piles so as to form continuous retaining walls in said trenches. The lower of the plurality of sheet piles being subsequently removable with a sideways movement, after excavation of a corridor by removal of the earth between said two walls, for insertion of prefabricated garages at an oblique or right angle into the vertical portions of earth thus uncovered.Type: GrantFiled: November 20, 1989Date of Patent: April 30, 1991Assignees: Armedio Clavarino, Ferruccio Clavarino, Lueca Clavarino, Massino Medri, Umberto CapelliInventor: Amedeo Clavarino

Patent number: 5002437Abstract: A method for aligning a series of posts begins with providing a first alignment apparatus adjacent a first hole. A first post is attached to one end of the alignment apparatus and hung at the desired elevation in the post hole. A second alignment apparatus is then provided and one end is connected to the first post such that the alignment apparatus may be swung about the post like a door. Once the second alignment apparatus is positioned in the desired orientation, support members are lowered to support the frame. A second post is then provided and hung on the opposite end of the second alignment apparatus at the desired elevation within a second post hole. The second post is plumed and aligned with respect to the first post upon attachment to the second alignment apparatus. Subsequent alignment apparatus and posts may be attached in a similar fashion to form a series of aligned posts.Type: GrantFiled: October 24, 1989Date of Patent: March 26, 1991Inventor: D. William Giroux

Patent number: 5002438Abstract: A method for lining or relining a sewer manhole, apparatus comprising an improved leak resistant manhole, and a cementitious mixture for lining/relining manholes. A homogeneous, monolithic, cementitious liner is spray applied in place within a concrete or brick-and-mortar manhole infrastructure without forms, webbing, or re-bar. A manhole to be serviced is first located and spray cleaned with water. Loose concrete and mortar fragments of the original structure are forcibly removed. A cementitious mixture is spray-applied to the interior surfaces of the manhole to create a continuous, monolithic interior liner. This lining is configured substantially identically to the internal shape and geometry of the manhole. When the liner sets after installation, a substantially impervious water and chemical resistant barrier prevents manhole ingress/egress by ground water.Type: GrantFiled: January 3, 1990Date of Patent: March 26, 1991Inventor: William A. Strong

Patent number: 4998849Abstract: A Kelly bar adapter for use with earth anchor driving machinery is disclosed. The adapter allows for pivotal connection of an earth anchor or earth anchor extension rod thereto. Thus, a vertically hanging Kelly rod may be attached to an earth anchor or its associated extension rod while the same is diagonally extending out of the ground. A tool for removing earth anchors having an integral eyelet or an eyelet which is threaded onto an earth anchor is also disclosed.Type: GrantFiled: September 12, 1990Date of Patent: March 12, 1991Inventor: Eugene R. Summers

Patent number: 4995761Abstract: An apparatus and method are disclosed for repairing ruptures in underground conduits. An inflatable bladder and a flexible sleeve that is wrapped about at least a portion of the bladder are introduced into a conduit proximate a rupture therein. The bladder is inflated to urge the sleeve into engagement with the conduit such that the sleeve covers the rupture. The sleeve includes an adhesive bonding substance that adheres the sleeve to the conduit and is hardenable to bond the sleeve to the conduit.Type: GrantFiled: August 23, 1989Date of Patent: February 26, 1991Inventor: Kenneth S. Barton

Patent number: 4995764Abstract: A foundation watering system includes a ground motion sensor which detects relative movement between a building and a stable soil zone beneath the building. The ground motion sensor includes a hole dug in the earth to a depth below a zone of shrinking and swelling a a rigid element embedded in the stable soil zone and extending upwardly to cooperate with a mechanism on the building. When the sensor detects significant downward movement of the periphery of the building, a valve is actuated to deliver water to the shrinking and swelling zone.Type: GrantFiled: April 13, 1989Date of Patent: February 26, 1991Inventors: Daniel P. Connery, D. Dexter Bacon, Stacy K. Blair

Patent number: 4988237Abstract: A system for extracting radon and other gases from a subterranean cavity beneath a floor slab and venting of collected gases to the atmosphere is provided which conducts cool, naturally occuring radon and other gases under high vacuum across a vacuum pump motor for cooling the motor. A vacuum pump is disposed within a housing chamber under vacuum. Cool gases within the housing chamber thereby conduct heat generated by the pump motor to the atmosphere.Type: GrantFiled: September 29, 1989Date of Patent: January 29, 1991Inventor: Geoffrey K. Crawshaw

Patent number: 4983077Abstract: A method of producing structural supports for use particularly in mining applications includes the use of a relatively rigid and cylindrical shell casing. The shell casing is separable along the plane parallel to its axis, has open ends and is closed about a fabric tube which is axially supported therein. The fabric tube is filled with pressurized liquid building materials such as concrete. Once filled within the casing, the pressure of the building material forces the liquid component thereof out of the tube laterally and through perforations provided in the shell casing to drain the liquid away from the building material in the tube. The casing and tube are of size such that the remaining building material, which will constitute a pillar, extends completely between the surfaces it is to separate and support.Type: GrantFiled: January 7, 1988Date of Patent: January 8, 1991Assignee: Gebhardt & Koenig-Gesteins- und Tiefbau GmbHInventors: Werner Sorge, Klaus Konieczny

Patent number: 4979489Abstract: A method is characterized by clamping a pile above and below a break-off line with simultaneous undercutting of the pile along the break-off line.An apparatus for carrying out the method has an upper power frame (1) and a lower power frame (3) positioned one above the other and connected to each other by means of hydraulic breaking cylinders (2). The power frames (1, 3) are made up of blocks (6, 11) defining a closed figure and pivotally connected to one another by means of hydraulic clamping cylinders (7, 13). The axes of the hydraulic cylinders (7, 13) run perpendicularly with respect to the longitudinal axis of the pile.Type: GrantFiled: August 2, 1989Date of Patent: December 25, 1990Inventors: Pulat A.

Patent number: 4978250Abstract: The faces (33) of the plate into which the gully is cast, are extended all around by lattices (40) of glass fiber. These form a compound with the subsequently poured plaster floor so that a tension-proof connection is ensured when the tiles are fastened by an adhesive or mortar. According to a preferred embodiment, the plate may additionally be anchored in the plaster floor by reinforcement wire meshes (41) cast into said plate.Type: GrantFiled: August 15, 1989Date of Patent: December 18, 1990Assignee: Firma Dallmer GmbH & Co.Inventor: Johannes Dallmer
