PURPOSE:To raise the accuracy of erecting a pile as well as eliminate the need for correcting the pile by a method in which a structural center pillar and a follower pillar are integrally connected while adjusting their vertical accuracies and the pillars are erected by hanging down them from the upper part of a structural center pillar-centering tool. CONSTITUTION:A pit 2 for a continuous wall is excavated, an iron bar cage is erected into the pit by a crane, and concrete is placed. Also, a Benoto pit 16 is excavated for correcting the vertical accuracy of the follower pillar 11 and the structural center pillar 10, and both the pillars 11 and 10 are connected by using a follower pillar setting tool 8. Then, both the pillars 11 and 10 are erected into the pit by hanging down them from the upper part of a structural center pillar centering tool 13 set at the top of the continuous wall pit 2. Lastly, after the structural center pillar 10 is stably erected, the centering tool 13 is removed and the pit 2 is back-filled with soil. |
