摘要

PURPOSE:To raise the bearing capacity of the pile foundation by a method in which a cylindrical casing designed to close the aperture between the tip portion and a hollow pile on the upper periphery of the pile is driven into the ground, and concrete is placed into the upper space of the pile and the casing or the footing. CONSTITUTION:A cylindrical casing 4 provided with a partial bottom 3 to close the aperture between the tip portion and a hollow pile 1 erected into the ground on the upper periphery of the pile 1 is erected into the ground.
