Publication number: 20090232607Abstract: A soil raining system combining flat sheet pile wails in an open cell configuration includes integral soil anchors providing an improved earth retaining system. Another aspect of the invention is a method of designing and installing a soil retaining system with an open sheet pile cell structure having integral soil anchors. The method includes, inter alia, calculating soil forces by taking into account material strength of sheet pile, soil friction against the sheet pile in combination with the strength of the integral soil anchor, selecting sheet pile size and length based on soil forces calculation; and installation of sheet pile to form a soil retaining system. The integral soil anchors serve to provide higher load resistance to the improved earth retaining system.Type: ApplicationFiled: January 5, 2009Publication date: September 17, 2009Applicant: Peratrovich, Nottingham & Drage, Inc.Inventor: William Dennis Nottingham

Patent number: 6530101Abstract: A multiple-use, cable-supported bridge in which the primary lateral and vertical deck-stiffening elements are prestressed cables, or strands, extending along one or both sides of the bridge, and methods of fabricating such bridges, are shown and described. One embodiment of the strand bridge of the present invention is designed to span from a first location to a second location. A first anchor member is fixed near the first location and an opposing second anchor member is fixed near the second location. A number of tensioned cables extend between the first and second anchor members. At least one post is attached to the cables at a point between the first and second anchor members. A cross member is attached to the post and projects from the post in a direction transverse to the lengths of the cables. Decking material extends from the first location to the second location, and can be coupled to the cross member.Type: GrantFiled: July 28, 2000Date of Patent: March 11, 2003Assignee: Peratrovich, Nottingham & Drage, Inc.Inventor: William Dennis Nottingham

Patent number: 5102261Abstract: A floating containment boom for containment and isolation of waterborne pollutants, such as oil, silt, medical waste, bacteria, debris, and suspended particulates. The containment boom is comprised of a floatation unit, a ballast, a continuous curtain of at least one sheet of a flexible geosynthetic fabric, and at least two tow cords. The curtain has an upper sleeve containing the flotation unit and may have a lower sleeve containing the ballast. The geosynthetic fabric is water-pervious and may be oil-absorbing. The fabric allows water to pass through while containing the waterborne pollutants. The boom of the invention may also be used as a seining device, to define a swim area, and as a littoral flow trap.Type: GrantFiled: January 16, 1990Date of Patent: April 7, 1992Assignee: Peratrovich, Nottingham & Drage, Inc.Inventor: William F.
