PURPOSE: A deformed cover forming structure of a pile for a temporary retaining wall with an extension joint and a method for drawing up the pile thereby are provided to cut down the construction cost by easily pulling up the pile without friction resistance with a drawing sheet, and to protect the pile by bending and mounting the synthetic resin sheet around the pile. CONSTITUTION: An upper pile(2) and a lower pile are connected by welded splice plates(1,1'), and drawing sheets(3,3') are formed in the upper part of the splice plates. The drawing sheets are contacted in the outer periphery of the pile, and a deformed cover(4) made of synthetic resin sheet is bent and formed in the entire surface of the pile including the drawing sheets. The bent ends of the deformed cover are opposed to each other, and mounted to each other by an additional tape. The thickness and the width of the drawing sheet are increased to be more than the thickness and the width of the splice plate. The drawing sheet is composed of the extension joint portion, and formed of Styrofoam material. |
