CAISSON TYPE PILE METHOD

摘要

PURPOSE: A caisson method is provided to improve resistance on earth pressure by the formation of a corrugated steel soil pipe having the shape of a strip along the outer surface. CONSTITUTION: A caisson method comprises following steps. In a construction position measuring step(S101), the position of a caisson type pile is measured for the construction of a concrete foundation. In a construction position excavation step(S102), a vertical shaft is firstly dug out vertically from the ground of the measured construction position. In a steel soil pipe installation step(S103), a steel soil pipe is formed to pour concrete inside the vertical shaft. In a concrete pouring step(S104), upper guide concrete is poured to support and fix the steel soil pipe inside the vertical shaft. In a second vertical shaft excavation step(S105), digging is performed from the bottom of the vertical shaft to the final depth.
