摘要 <p>A template levelling system includes a pile receptacle carried within the template receptacle mounted to the template. The pile receptacle has a lower flange that extends outwardly from and below the template receptacle. Slips are located in the pile receptacle for gripping the pile to prevent downward movement of the template. A hydraulic jack will grip the pile receptacle and pull the pile receptacle upwardly, causing the flange to contact the lower side of the template to lift the template. The pile receptacle is laterally movable in the template receptacle. A release sleeve can selectively release the slips to allow the pile receptacle to be lowered on the pile.</p>
