Abstract
Disclosed is a two-part caisson-clamp, wherein each half of the caisson-clamp contains only one jaw face. The two half caisson-clamps together pinch the top of a pile between them. The jaw faces may have a concave curve to secure the pile between them. The pile extends up between the two caisson-clamps to contact the caisson-beam. Horizontal forces on the two caisson-clamps, which would otherwise drive the two caisson-clamps apart, are resisted by mechanical stop(s). A mandril may be inserted into the pile to reinforce the top of the pile relative to the forces applied and transferred by the half-caisson clamps.
