Abstract

PURPOSE:To raise the operating efficiency for pile head treatment by a method in which before concrete placed into a pit hardens, a high-pressure water jet pipe having a nozzle on its tip is inserted into the concrete in a height regulable manner and high-pressure water is jetted. CONSTITUTION:Before concrete 2 placed into a pile pit 1 hardens, a working bench 4 having a round guide slit 4d on its center is set on the pit 1. A high- pressure water jet pipe 5 having a jet nozzle 5a on its tip is inserted into the extra-banking portion 2a of the concrete 2 through the slit 4d, and high-pressure water is jetted while turning the pipe 5 by operation of a handle 5b. Since the high-pressure water jet can be moved along the slit 4d, high-pressure water can be jetted onto all the extra-banking portion and workability for the pile head treatment can be enhanced.
