Abstract

PURPOSE: To easily draw out steel materials from hardened soil concrete by a method in which a master pile consisting of combined two steel materials is erected in a soil concrete pillar not hardened and then an expansion pressure by a blasting chemical is applied to the outside of the steel materials.
CONSTITUTION: A pit is excavated under the ground 1 to a given depth by an auger, a row of soil concrete pillars 2 are constructed, and then before the soil concrete is hardened, a master pile 5a consisting of combined steel materials 3 with a hollow 4 is erected in the soil concrete. A vertical hole 6 is formed in the soil concrete 2 throughout the vertical whole length of the steel materials 3 in contact with their outside, and then after the soil concrete 2 is hardened, or the completion of underground work, a blasting chemical 7 is enclosed in the hole 6 and fired. Whereupon, a temporary stopper means 12 between the steel materials 3 is broken by an expansion pressure produced by the abrupt combustion of the blasting chemical 7 and thereby the steel materials 3 are moved to the hollow, thus permitting the steel materials 3 to be easily drawn out of the soil concrete.
