Abstract

PURPOSE:To form a highly compacted layer around a pile buried underground by a method in which an excavating blade is inclined backwards in relation to its rotation direction and the ground around the excavating blade is compacted. CONSTITUTION:When a rotation shaft 6 is turned in the arrow direction and a pile 4 is lowered by its own weight and the loader of an upper device while excavating the ground below the pile 4 by means of a rear plate 8 and an outer edge blade 9, a screw 15 is turned in the direction of holding down excavated soil and sand, the downward pressure of the screw 15 and the descending pressure of the pile 4 act on the excavated soil and sand, and the excavated soil and sand near the outer edge blade 9 becomes triaxially compressed state and pressed in the original ground region. On the other hand, the excavated soil and sand not pressed in the region goes up from the aperture between the surrounding ground of the pile 4 and the screw 15 and the soil and sand coming along the periphery of the pile 4 becomes densed structure and pressed on the periphery of the pile 4.
