Sutton, J S

A piling-jacket system is described including an elongated, hollow, piling jacket of flexible material having a top end and a bottom end for receiving grout therein and retaining the grout during the curing thereof for forming a concrete column therewith, the piling-jacket system comprising: a filling-port means located on the side of the piling jacket intermediate the top and bottom ends thereof, the filling-port means including an open port in the flexible-material jacket, a flap of flexible material mounted adjacent the open port on an interior surface of the piling jacket, and a flexible flap cord attached to the flap at an outer end portion thereof and extending through a cord hole defined by the flexible piling jacket to the exterior thereof; whereby a concrete-supply hose can be inserted through the open port thereby holding the flap away from the open port through which wet concrete can be pumped into the interior of the piling jacket and thereafter, once a top surface of the wet concrete is above the open port, the flexible concrete-supply hose can be pulled out of the open port so as to allow the flap to close the open port, and the flap cord can be pulled outwardly to positively pull the flap over the open port and thereby preventing wet concrete on the interior of the piling jacket from passing through the open port to the exterior thereof.
