摘要： PURPOSE: To make the chipping operation of pile head easier as well as reduce the occurrence of noise and vibration by a method in which an aqueous solution of a viscous high molecular compound is added to and mixed with the extra- banking portion of the heat of a concrete pile to lower the setting property of concrete in the extra-banking portion.
CONSTITUTION: Concrete 1 for in-situ pile is placed, and then water mixed with a viscous high molecular compound is injected into the concrete 1. The amount of the high molecular compound to be added is controlled to 0.1W5.0% of the weight of water. When they are mixed while turning a propeller-shaped mixer 2, the concrete 1a of the extra-banking portion becomes of much lower strength. The pile head treating operation is ended by partly using a motor driven pick. The needs for breaker or compressor can thus be eliminated, and the total cost for treating the pile head can be greatly curtailed.
