Patent number: 6854536Abstract: The present application relates to a tool having a cutting apparatus for enlarging a portion of an underground pile shaft. The tool is provided with a collecting device which is disposed below the cutting means in order that spoil generated when performing a cutting action on ground material surrounding the pile shaft can be collected. The size of the collecting device is adjustable thereby allowing the volume of spoil which may be accommodated by the collecting means to be varied. A compacting mechanism for compressing the spoil collected in the collecting device may also be provided for reducing the volume of the spoil.Type: GrantFiled: January 14, 2002Date of Patent: February 15, 2005Assignee: Cementation Foundations Skanska LimitedInventors: Melvin Gerrard England, Ronald Peter Payne

Patent number: 6739805Abstract: A waterstop, 10 or 11, for restricting or preventing the flow of water across the joints of foundation elements 8, such as between or along individual diaphragm wall panels or between or along individual secant wall piles. The present invention also relates to a method of installing a waterstop at or near the joints between adjacent foundation elements. The waterstop consists of one or more longitudinal strips, 1 or 2, of hydrophilic material, wherein the or each hydrophilic strip extends vertically along the interface between adjacent foundation elements, from a position at or near the top of the foundation elements, to a position at or near the base of the elements.Type: GrantFiled: January 15, 2002Date of Patent: May 25, 2004Assignee: Cementation Foundations Skanska LimitedInventor: Peter Gilbert Shotton

Patent number: 6641333Abstract: The present application relates to a method of installing a pre-cast pile in the ground which involves applying an enlarged head forming tool to the ground until a volume of soil has been displaced or removed so as to form a void at the surface of the ground. The pre-cast pile is then driven into the ground to a predetermined depth below the void and the void is then filled with concrete or grout to form a cast-in-situ pile head. The diameter of the pile head is greater than the diameter of the pile shaft.Type: GrantFiled: August 8, 2002Date of Patent: November 4, 2003Assignee: Cementation Foundations Skanska LimitedInventors: Graham Bartlett, Melvin Gerrard England

Patent number: 6394703Abstract: A method and apparatus for forming a capping beam across two or more cast-in-situ piles (11), wherein a precast or preformed guide wall structure (1) having holes (5) for receiving and guiding a piling auger is placed into an excavation, forming a number of cast-in-situ piles (11) by applying a piling auger to the ground through the holes (5) in the guide wall structure (1), removing the guide wall structure (1) and filling the excavation with concrete so as to form a capping beam. This results in much improved construction times, since it is not necessary to remove excess hardened concrete before forming the capping beam, and also results in less waste, since the guide wall structure can be reused.Type: GrantFiled: January 25, 2001Date of Patent: May 28, 2002Assignee: Cementations Foundations Skanska LimitedInventor: Peter David Renouf

Publication number: 20020056590Abstract: The present application relates to a safety apparatus which is intended to aid the balance of an individual working on an elevated surface such as a horizontal mast 1. The apparatus, which consists of a support member 5 that projects up from the elevated surface, may also arrest the fall of an individual from an elevated surface by defining a support barrier in front or behind or either side of the individual. The support member may be adapted to be mounted within tool tracks already provided on a mast, and is designed to move along the tracks so as to balance the individual as he moves along the elevated surface. Alternatively, the elevated surface is provided with additional purpose-built guides or tracks designed to cooperate with the support member.Type: ApplicationFiled: November 14, 2001Publication date: May 16, 2002Applicant: CEMENTATION FOUNDATIONS SKANSKA LIMITED Rickmansworth, United KingdomInventors: James Donald Goldie, David Buxton, Michael Holland
