PURPOSE:To obtain exactly strong frictional bearing capacity by a method in which a pile to be buried whose cross section is increased from the lower end to the upper end is erected into a pile pit and a static load higher than the ultimate load of the upper end of the pile is applied to the pile. CONSTITUTION:A pit 40 is excavated in the ground 4, and a pile 1 is lifted up and down to the center of the pit 40. The pile 1 is then penetrated into the pit 40 under its own weight and the lower end 10 of the pile 1 becomes slightly pressingly penetrated. A load plate 2 is penetrated from above the guide strut 30 of a guider 3 and slowly put on the upper end of the pile 1 to apply static load to the pile 1. Load plates 2 are then increased in order to increase static loads to be applied to the pile 1 stepwise until the total loads exceed the ultiminate load of the pile 1, and thereby the whole length of the pile 1 is buried under the ground. The penetration of the pile 1 into the pit of the ground can thus be made easier, and strong frictional bearing capacity can be surely obtained.
