METHOD FOR ERECTING COLUMN FOR GUARD FENCE AND COLUMN
PROBLEM TO BE SOLVED: To provide a technique for erecting a column for guard fence which can erect a column simply without boring by using a down-the-hole hammer and which can greatly reduce cost for erecting a column.SOLUTION: In a method for erecting a column for guard fence, a consolidation jig 80 which can be internally inserted in a column comprising a hollow pipe body with open upper and lower ends and which can be struck is used, and by striking the consolidation jig 80, a part of an external pipe 30 composing the column with the consolidation jig 80 is penetrated into the ground and is erected, and sediment taken in the external pipe 30 is consolidated by the consolidation jig 80 so that a consolidated soil mass Gis formed. A consolidation material is packed in the whole area of the inside of the external pipe 30 blocked by the consolidated soil mass G, and the consolidated soil mass Gand the consolidation material are integrated by the external pipe 30.SELECTED DRAWING: Figure 8A
【課題】ダウンザホールハンマを用いた削孔をせずに支柱を簡易に立設できて、支柱の立設コストの大幅削減が可能な防護柵用支柱の立設技術を提供する。【解決手段】上下端を開口した中空構造の管体からなる支柱に内挿して打撃可能な圧密治具８０を使用し、圧密治具８０を打撃して圧密治具８０とともに支柱を構成する外装管３０の一部を地中に貫入して建て込み、外装管３０内に取り込んだ土砂を圧密治具８０で圧密して圧密土塊Ｇ１を形成し、圧密土塊Ｇ１で閉鎖した外装管３０の内部全域に固結材を充填し、外装管３０を介して圧密土塊Ｇ１と固結材とを一体化する。【選択図】図８Ａ
