<p><P>PROBLEM TO BE SOLVED: To provide a drip receiving device of hydraulic solidifying liquid and a construction method of a column replaced with hydraulic solidifying liquid, which prevent the hydraulic solidifying liquid attached to a drilling auger or remaining in a supply passage of the drilling auger from dripping down to the ground surface during redeployment of a construction apparatus to the next construction position after construction of a replaced column, so that the ground surface is prevented from being stained with the hydraulic solidifying liquid; and which also prevent a viscous dug sediment attached to a drilling claw from falling into a still uncured replaced column to deteriorate quality of the replaced column as a contaminant. <P>SOLUTION: A drip receiving container 12 having an opening on the upper side is detachably suspended through suspension means 13 at a tip of a drilling auger 6. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
