METHOD AND APPARATUS FOR LIFTING AND SECURING A CONCRETE PANEL IN PLACE ABOVE A ROAD BED

摘要

An apparatus to be embedded within a precast concrete panel or slab to enable the panel to be lifted, moved to a road bed, and secured in place above the road bed. A lifting apparatus is embedded at each corner of the panel. Each apparatus has a hollow threaded sleeve extending through the panel to receive a removable threaded lifting bolt by which to establish a lifting point at which a lifting force is applied to lift and position the panel on support blocks seated on the road bed. When the threaded lifting bolt is removed from each hollow threaded sleeve, grout is pumped through the panel by way of the hollow sleeve to fill the space established by the support blocks between the panel and the road bed. The method and apparatus have particular application during construction or repair of a roadway.

1. A method for lifting and transporting a concrete panel to a surface and retaining the panel in place above the surface, said method comprising the steps of:
embedding within the concrete panel at least one hollow sleeve that runs through said panel; coupling a lifting bolt to said hollow sleeve; applying a lifting force to said lifting bolt by which the concrete panel is lifted and transported to the surface; uncoupling said lifting bolt from said hollow sleeve after the concrete panel has been transported to the surface; and pumping a curable filler material through said hollow sleeve for receipt below the concrete panel.
