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.
