DRAWING WORK OF REINFORCING PILE WITH CUT IN SHEATHING WALL

摘要

PURPOSE: To raise the efficiency of construction by a method in which an impact is applied to the top of a reinforcing pile exposed to release the close adhesion with the sheathing wall, and the reinforcing pile is drawn out. ;CONSTITUTION: In pulling out a reinforcing pile 1 having a cut in its intermediate part corresponding to a removing length, the sheathing wall 31 around the pile 1 is chipped to form a recessed part 5 around the pile 1. An impact such as striking and vibration is applied to the top of the pile 1 by an impacting means 8 to release close adhesion between the pile 1 and the wall 31. The reinforcing pile above the cut portion is drawn out by using a drawing machine, and the hole formed after drawing is packed with sand and soil and tamped. The reinforcing pile can thus be quickly, simply, and safely drawn out at low cost while preventing damage such as bending to the reinforcing part.;COPYRIGHT: (C)1993,JPO&Japio
