Abstract

A pile jacking sleeve includes a structural sleeve having a bottom section, an intermediate section and a top section. A stationary plate partitions the bottom section from the top section. A floating plate separates the intermediate section from the top section. A hinged door at the top section allows lateral entry of a piling into the top section when the door is open. An aperture allows insertion and removal of at least one jack into the intermediate section. Actuation of the jack urges the floating plate away from the stationary plate, controllably imparting a load to installed piling. A plurality of bolt holes are also provided in the sleeve to secure piling thereto. The sleeve may be jacketed for additional protection. A plurality of grout windows are also provided in the sleeve to enable filling the structure with a solidifying filler.

Dependent claims

A unitary pile jacking sleeve comprised of:

a bottom sleeve section, an intermediate sleeve section and a top sleeve section, said bottom sleeve section, intermediate sleeve section and top sleeve section being adapted to structurally support a design load;
said bottom sleeve section having an open bottom end and a top end attached to said intermediate section, and said bottom section being adapted to receive through said open bottom end of said bottom section the top end of a bottom pile that has a bottom end secured in a ground;
said top sleeve section having an open top end and a bottom end attached to said intermediate section, and said top section being adapted to receive the bottom end of a top pile that extends from the open top end to a supported structure, and said design load being greater than the weight of the top pile;
and
said intermediate sleeve section being disposed between and adjoining said top sleeve section and said bottom sleeve section;
and
further comprising a floating plate separating the intermediate sleeve section from the top sleeve section.
