Abstract
PURPOSE: To effectively eliminate negative friction imposing on a support pile by providing a rib on the periphery of the pile and also covering the peripheral surface of the area between the ribs with a synthetic resin sheet.
CONSTITUTION: A support pile 1 is provided with ribs 3 fixed at the upper end, lower end, and intermediate portions of its peripheral surface, and a synthetic resin sheet 2 is covered and fixed on the peripheral surfaces of the areas between the ribs 3 by means of a fixing band 4. When the support pile 1 is erected under the ground, negative friction encountered just after being driven is eliminated by an aperture 6 formed between the ground and the peripheral surface of the pile by virtue of the ribs 3. After the pile is driven, the ground around the pile is consolidated, whereupon, even if negative friction exerts on the pile body, the negative friction is also eliminated by means of the tensile strength and elongation of the synthetic resin sheet 2 covering the peripheral surface of the pile body. Thus, no negative friction occurs on the pile body.
