Zusammenfassung: | A PHC pile having a leading end reinforcement shoe is provided to minimize the influence of slime, to decrease the degree of subsidence by driving into a stable bearing layer, and to increase the bearing capacity for a leading end by increasing the area of a leading end. A PHC pile having a leading end reinforcement shoe comprises a PHC(pre-tensioned spun high strength concrete) pile(10) formed in the shape of an empty cylinder and having a leading end surrounded by a reinforcing band(11), and a reinforcement shoe(20) having the top welded to the leading end of the PHC pile and the bottom formed in the shape of a triangular pyramid projected downward to expand the diameter of the PHC pile and to penetrate easily, wherein the reinforcement shoe comprises a cylinder pipe(21) inserted with the leading end of the PHC pile and welded with the PHC pile, a hollow reinforcement plate(22) coupled to the bottom of the cylinder pipe and having the larger outside diameter than the outside diameter of the PHC pile to increase the bearing capacity of the leading end of the PHC pile, and an excavation reinforcement plate(23) composed of a first excavation reinforcement plate coupled perpendicularly to the bottom of the hollow reinforcement plate and having the shape of an isosceles triangle and a pair of second excavation reinforcement plates coupled perpendicularly to the bottom of the hollow reinforcement plate and having the shape of a right-angled isosceles triangle to penetrate easily when driving. |
