METHOD FOR CONSTRUCTING HYDRAULIC SOLIDIFICATION MATERIAL LIQUID SUBSTITUTION COLUMN, AND CLOSING BODY FOR CONSTRUCTING HYDRAULIC SOLIDIFICATION MATERIAL LIQUID SUBSTITUTION COLUMN
PROBLEM TO BE SOLVED: To provide a hydraulic solidification material liquid substitution column having a diameter (cross section), strength, and quality as planned, which is obtained by preventing an internal diameter of a drilled hole from being reduced or deformed, by preventing liquid level rising or overflow of hydraulic solidification material liquid by tightly closing the inside of the drilled hole before solidification of the hydraulic solidification material liquid after constructing the hydraulic solidification material liquid substitution column.SOLUTION: Before hydraulic solidification material liquid has solidified in a drilled hole after constructing a hydraulic solidification material liquid substitution column, a closing body 1 for tightly closing the inside of part of the drilled hole above a predetermined upper end level of the hydraulic solidification material liquid is loaded inside the part of the drilled hole.
【課題】水硬性固化材液置換コラム築造後の削孔内の水硬性固化材液がまだ固まらないうちに、削孔内を密閉して水硬性固化材液の液面上昇や溢れ出しを防止することにより削孔内径の縮小や変形することを防止して、計画設計通りの径（断面積）および強度、品質の水硬性固化材液置換コラムを提供する。【解決手段】水硬性固化材液置換コラム築造後の削孔内の水硬性固化材液がまだ固まらないうちに、該水硬性固化材液の所定の上端レベルの上方の削孔内に、該削孔内を密閉する閉塞体１を装填する。【選択図】図１
