NON-STRUCK PILE HAVING LARGE TOP EDGE SUPPORTING YIELD STRENGTH AND PILE CONSTRUCTION METHOD AND DEVICE THEREFOR

摘要

PURPOSE:To construct a non-struck pile having a large top edge supporting yield strength by a small thrust by constructing a pile body on a rod-shaped collected body consisting of rigid pieces which is buried into a supporting ground. CONSTITUTION:After a pile hole 8 is excavated on a ground 1, a rigid body holding part 10 which holds a collected body consisting of rigid body pieces 3a is suspended by a crane, etc. Then, a reaction force is received by a reaction force receiving part 12 position-fixed by a spread reaction force plate 1, and the rigid body pieces 3a are buried into a supporting ground by a hydraulic jack 11. Then, a buried pile or a placing concrete pile is constructed on the collected body 3 consisting of rigid body pieces 3a.
