Pillar building fundamental construction manner

摘要

PURPOSE:To permit columns to be constructed strongly on soft ground by a method in which a consolidated foundation if formed at a given depth, a consolidated column area is formed above the foundation, and the column area is excavated to form column pits. CONSTITUTION:A soft ground is excavated to a given depth by a small-diameter earth auger at first, and a consolidating material is forcibly sent from the tip of the auger into the pit and strongly consolidated to a consolidated foundation 10. The upper area of the foundation 10 is excavated by a large-diameter earth auger with the same diameter and consolidated to form a consolidated column area 12. The area 12 is further excavated to the top of the foundation 10 by the small-diameter earth auger to form a column-constructing pit 13. A pole 3 is erected in the pit 13.
